Preface
Hi !
In my reading of various threads it's become apparent that there are MANY people who passionately
desire a "real FM radio" app. Not all of us live in data dense areas, or can afford the costs of
streaming audio. And not all of us have given up on RF broadcasts, either due to our tastes,
local available programming, lack of commercials or whatever. And many of us very much desire
the ability to transmit on the FM band for various reasons.
I want this thread to deal with TI FM radios on all devices that contain TI chips. My observation is that
there is a great deal of commonality in the TI chips supporting FM in the last 4-6 years.
I don't generally want to deal with the Broadcom FM chips here, but the audio routing issues will be similar.
I also WOULD like to create a list of devices containing the FM chips they use, so people can more quickly
determine their FM chip type.
To non-devs who want FM yesterday: Yes, I know. No need to post about it. I'll do my best to create some
kind of app ASAP, but first some fundamentals need to be figured out. I'd think and hope that others will also
be able to create FM radio apps from the info here and elsewhere.
This thread is in a developer forum, and as such it would be preferable to limit discussion to technical
aspects, preferrably by those who are developers or thereabouts in terms of technical skills. It's hard
work sometimes to slog through near 100 page threads such as the one for the Nexus One FM radio.
If you have simple questions, comments, requests, corrections or additions to this, please consider
PMing me directly and I'll do my best to incorporate that into the thread, giving acknowledgement
if you so desire.
That said, I've posted FM Receiver and FM Transmitter scripts below. If you feel you have a reasonable
capability to try these scripts on your device, please do, and report here or via PM on success or failure
if you might be among the first few to try these on your device/model.
I will try to keep these first posts updated with the latest information, so hopefully you won't need to post
questions about whether or not your device works by referring to the "Devices" post.
---------------------
Introduction
I've enabled the FM radio functions on my HTC Legend. It is also known to work on HTC Tattoo.
Scouring the web looking for the magic incantations to enable FM audio I'm finding myself overwhelmed with all the things I don't know.
Much of the information needed is kept under wraps by TI and their customers. To get TI's information requires signing an NDA,
and perhaps other legal documents. Signing such an NDA limits how much you can say publicly, and I'd prefer to not be under
such constraints. I'm not even sure if an NDA would be sufficient for a person not employed by TI or a TI customer.
Thus this thread, to share with you the information I've found, and to ask for your help in correcting it or adding to it.
If there is any similar thread on any site, that is TI specific, but not device model specific, please let me know.
I've seen and read through a number of mega-threads here and elsewhere that are device specific, but much of the information
contained therein is useful for all devices with TI FM chips.
The chips in question are usually named: WL1271, WL1273, WL1281 and WL1283. The first two have WF + BT + FM and the latter two add GPS.
TI also calls these WiLink or BlueLink 5.0, 6.0 and 7.0, as well as BRF6300, BRF6350 and BL6450.
TI also sells various evaluation boards carrying these chips, and some TI partners produce modules, sometimes with similar numbers.
AFAICT there is no FM functionality in some of the predecessor chips such as the WiLink 4.0 chips: BRF6100 (WL1251) & BRF6150 (WL1253).
Just so you better know my knowledge level:
- I'm new to Android, smartphones and post 1995 PDAs, although I've read some on these subjects over the years.
I'm diving straight in to learn as much as I can as quickly as I can. I'm not currently employed but hope to
transition myself to what appears to be the rapidly expanding Android world.
- I've worked in software development on "semi-embedded" Linux VOIP and security appliances since 1997, with a good bit
of low level kernel/driver stuff. Not much low level stuff recently, mostly daemons and command line utilities.
At home I've recently worked on a home Asterisk VOIP box and MythTv and XBMC based HTPCs. I also manage the 5 Ubuntu
PCs our family uses, as well as one lonely 5 year old HP WinXp tablet.
- My background in electronics and computing goes back to the mid 1970's with 8080 and SCMP. I designed and built a variety
of computer, electronics and even RF devices in those days, and can still wield a mean soldering pencil when needed.
-----------------------------------------------------------------------------------------------------------------------------------------------------
Here is some information about which chips being discussed here. Note that the terms BlueLink and WiLink can be somewhat confusing as some chips are both.
TI's Wireless Connectivity Solutions page:
http://focus.ti.com/general/docs/wt...lateId=6123&navigationId=12493&contentId=4637
Note at left that GPS (NaviLink), Bluetooth (BlueLink) and Wireless (WiLink) are represented.
FM radio seems to be the neglected "step child" that gets little mention or notice.
It's a small add-on feature that just happens to come along with Bluetooth sometimes, if at all.
Generally, the WiFi, BT, FM and GPS components in these multi-function chips tend to be independent of each other.
They can be powered up or down individually and usually have seperate control paths. They are called "IP"s, eg.
the WiFi IP or BT IP. I haven't yet determined what IP stands for, LOL.
FM is the exception though; it seems to piggyback on the BT IP. To power up FM you must first power up BT
(although some doc implied BT can then be powered down). FM has it's own I2C control path, but that is usually
not used, in favor of sharing the BT HCI interface.
Some docs I've read discourage the use of FM. Perhaps it can cause issues ?
Note that some of these chips may indicate support for Wireless-N, but that doesn't mean the device manufacturer
enabled it in their stack etc. It might be possible to enable N, perhaps with different Wireless firmware or init
scripts. While an interesting prospect, despite the expectation of vastly increased battery consumption, I don't
want to get into the Wireless issues, except as they might impact FM.

Sources
Sources
The source of information I've found include:
- Documents from TI or customers. Usually these contain limited information.
- Source code from TI, TI's customers or other parties, including ROM builders.
- Threads/Posts on forums including this one, as well as TI support forums.
- Miscellaneous random sources such as IRC logs for HTC-Linux.
The most comprehensive and easily useful sources I've found so far are the source codes
for a Linux WL1271 driver being produced by a Nokia employee, and somewhat similar
source codes from TI.
The "Texas Instruments WL1273 FM radio" Linux driver is under development by Matti J. Aaltonen
of Nokia. I believe the Nokia N900 uses a TI chip under Maemo->Meego, and perhaps other Nokia
devices too. Various patches and discussions are underway, and can be googled, and parts of it
are slowly appearing in the latest kernel source. If you want to see the latest, the only easy way
seems to be downloading one of the latest kernels at https://lkml.org/ .
There's an ancient first version from and some discussion from April here:
http://thread.gmane.org/gmane.linux.drivers.video-input-infrastructure/18449
I used http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.37.tar.bz2 and
http://www.kernel.org/pub/linux/kernel/v2.6/patch-2.6.37.bz2 but I see there's a 2.6.38 RC5
there as well.
Finding and downloading TI code has been a pain, but they have a lot there.
TI WL 128x FM V4L2 driver:
There's a git repository for what appears to be an alternate V4L driver at http://dev.omapzoom.org/pub/scm/manju/L24x-btfm.git
Some discussion: http://www.spinics.net/lists/linux-media/msg28310.html
I'm not sure why there appear to be two efforts underway to create FM V4L2 drivers, the one by Nokia and the other by TI.
This appears to be source for TI's fmapp test utility and fm_stack library in a form that can be viewed by browser:
http://git.omapzoom.org/?p=platform...2a9dcca2dced00e724a2eb1dec578152f5beb;hb=HEAD
I managed to download the older 0.12 version of fmapp and fm_stack source code from somewhere, but can't recall where.
The "fmapp" utility has a LOT of functionality for testing just about every exposed FM feature, including RDS.
There is also a recently released "Android Froyo DevKit V2" at:
http://software-dl.ti.com/dsps/dsps_public_sw/sdo_tii/TI_Android_DevKit/02_00_00/index_FDS.html
You have to sign in for that but it should be easy to create an account. I already had one via a previous TI adventure.

Devices
List of devices and FM chips. At this time I'd like to limit this to Android devices, but might consider others.
Would be useful to list limitations here. For example, some Motorola Droid owners were understandably disheartened,
after much work, to find they had no Fm Rx antenna connection, and could not make one without opening up the cans, etc.
on the board. So technically they had Fm Rx, practically, they had none.
Also, some boards may have no Tx antenna, but might possibly work within a few inches of an external FM receiver antenna.

FM Apps and APIs
FM Apps and APIs
Many handset manufacturers provide their own proprietary FM radio apps. Some people have managed to get an
FM radio app meant for another device working on theirs. Most, however, have library or other issues with a foreign app.
AFAICT, Google has not released any sanctioned FM radio API, nor do they intend to. I'd guess FM radio likely
won't bring much revenue to Google or the carriers.
In an ideal world, Android apps would use the same API as on Linux: the "Video For Linux version Two" aka V4L2.
This API makes use of a /dev/radioX device. This is somewhat similar to the /dev/videoX devices that some devices
appear to support for cameras.
If the V4L2 API was available on Android, Android FM radio apps could then be ported more easily from Linux.
Alas, there are relatively few Linux radio apps. GnomeRadio hasn't been touched in over 2 years and Gnome
doesn't run on Android anyway of course. Some command line apps could be ported, but that doesn't make for
an Android app.
So thus far, the defacto "API" for FM radio on Android has been vendor specific commands over HCI, the
Bluetooth interface. This is more or less similar to the way it can be done via I2C, but apparently
most FM chips are not wired via 12C; they use the existing HCI UART. Once again, FM radio is the
poor neglected "step-child".
One advantage of using HCI is that no new kernel drivers are needed. A disadvantage is that some mediation
driver would be required to use bluetooth and FM at the same time; the only alternative being drivers for
both smashed together, but that would be an Android specific hack and is not a good idea.
I've noted that one individual created an API spec and an app for Windows devices a few years back.
I believe it was called GFMRadio and XFMRadio or similar. That project was apparently abandoned.
MIUI released a GPL licensed FM app for some phones based on broadcom chips; HTC Desire and Nexus One.
The source code contains the string "/dev/radio", but AFAICT it doesn't appear to actually use V4L API.
It speaks directly to the broadcom FM chip via HCI.
Since MIUI source is GPL and available it could be used as a base for a TI, or TI and broadcom specific app.
In theory patches could be submitted to MIUI but I'm not sure they are open to that and the language barrier
from English to Chinese and back may be difficult.
Some interesting posts on MIUI here: http://forum.xda-developers.com/showthread.php?t=837691
http://www.miui.com/thread-1687-1-1.html
Using hcitool commands, or similar, one could write a radio app in bash or Perl etc. LOL.
TI has an "fmapp" command line testing utility that relies on libfm_stack.so .
This app won't run on my Legend because it depends on snd_ctl_* APIs in libaudio.
"strings libfm_stack.so" produces lots of interesting detail and embedded BTS scripts.
The source code I've found for TI fmapp, and it's FM stack library does not seem to have all
the functionality I've seen in the binary fmapp I found. So they may have stripped much code
for the publicly released source code.
Audio routing
Audio routing
On HTC phones, FM analog audio routing can be achieved by:
# Default
adb shell 'echo "disable" > /sys/class/htc_accessory/fm/flag'
# Headset
adb shell 'echo "fm_headset" > /sys/class/htc_accessory/fm/flag'
# Speaker
adb shell 'echo "fm_speaker" > /sys/class/htc_accessory/fm/flag'
# View
adb shell cat /sys/class/htc_accessory/fm/flag

Firmware, TI BTS file, HCI and I2S/I2C issues, tools etc.
The Nokia V4L driver loads radio-wl1273-fw.bin, although the code does indicate it may not be necessary.
I can't find this firmware file anywhere. As with many other firmwares, it may simply be a known firmware
file renamed. This has been noted with other firmware files for the TI radio.
Information on firmware for these TI chips seems scattered and incomplete. Same with the BTS Bluetooth script files
which are usually important for accessing the FM functionality.
I think one of the reasons for this lack of information is that most parties do not want us messing with the available functionality.
- Device manufacturers do not want their devices used in violation of FCC or other regulatory body rules.
For example, FM transmission at higher power levels or improper frequencies. Also RDS transmissions with bogus data.
- Device manufacturers and carriers want us to buy newer or more expensive products for additional functionality.
They also would rather we use voice minutes instead of FM "walkie talkies".
- Google and carriers want us to stream music via data rather than pick it up for free from over the air.

I think you are doing an awsome job and I really hope that you'll succeded. But the reason why I'm writing this post is to get this thread on the first page again for a while, so maybe more developers will see it, and can contribute !
Good luck!
EDIT: Perhaps it just needs more outstandig title, maybe Unviersal FM radio for android devices with TI WL chips, or something that would get people to read it.

It's already off the first page, LOL.
My plan has been to post a link to this thread in the various existing threads for different devices using the TI FM chips. I'm sure that will get this thread some notice. I think a lot of devs and dev types stick to the forums for their devices and don't look at this general section.
At least there are so many potentially matching keywords in the first 10 posts that google searches on the subject are likely to link here.
I agonized over the thread title name for some time and "TI FM Radio" is best description I could think of, technically at least. I don't know if I can rename the thread, but it might help to put the names of popular devices with TI chips in the title.
As I posted on the Legend thread, I now have an App Inventor app up and running with functionality to tune, scan, change volume and see signal strength. The audio routing is the last major piece of the puzzle, but it may be different on different devices.
I'll spend a few more days at most to try and get audio routing working, and then, whether working or not, I'll post in a few threads looking for further info and people who want to try the app I'm building.
Would be nice to see the RDS and transmitter working soon too.
Regarding merging the bluetooth and FM drivers, TI's solution appears to be what they call a shared transport line discipline driver. The way this should work, each driver has what appears to it to be dedicated access to it's respective core, and the line discipline driver takes care of any queueing or delaying of commands & such that has to happen to keep them from stepping on each others toes.
Oh, and "IP" is "Intellectual Property" in this case. So the core, generally you'd say the WL127x has a wifi core, bluetooth core, etc. and 128x has a gps core as well. An IP core uses a description language (it used to be VHDL) to describe the layout of the core, so for instance if a company wants to build wifi onto their own chip, they can buy use of the IP core from TI instead of having to buy a phyiscal chip and interface to it.
I've got a debian install wedged onto my Droid 2 Global, I'm going to look into the "ti-st" V4L2 FM drivers, and see if I can get a module that will insert. The kernel can't be replaced on D2G yet, but as far as I know if I get a 2.6.32.9 kernel tree, and get ti-st driver to compile under it, I don't see why it shouldn't insert as a module just fine. Also, I'll look REAL closely to see if I can discern how it gets audio out, so I might have an hcitool command or two to add if that pans out.

Thanks for the info hwertz .
OK I understand "IP" now; never heard it used in that way to designate blocks on a chip.
Yes I read something about the line discipline. Some block diagrams: http://omappedia.org/wiki/Wilink_ST
If you know of any HCI commands dealing with audio routing, please post or pm whatever info you can share.
So I'd guess your opinion is that the v4l2 api is the best route to support FM radios on Android ? That was among my first thoughts until I saw that there is currently virtually no such support on any Android ROM I've heard of. HCI seems to work fine, but it requires chip specific commands of course.
Clearly though, at least Nokia and TI both are working on efforts to bring V4L2 apis for the TI chip in the embedded linux or Android environments.
I'm not sure how audio routing would be configured on Android when using v4l2 apis. The PC environment requires moving digital data from source to destination. But SOC devices often can move digital or analog data directly and without software support.
FM Transmitting Radius
So I hope this question is not too basic for this forum, but I'm new to it and wonder how large the FM transmitting radius of such a chip might be. I basically just need to get an idea, but of course I'd also be thankful if you can refer me to all sorts of literature, specs, overviews, etc.
Thanks!

This thread is over 2 years old now. The original purpose was to try and find others interested in sharing the undocumented secrets of TI's FM chip.
But after my info dump, nobody showed up to share with me, and likely nobody will, so I will close it after this post.
Any further discussion about FM can move to the Spirit FM thread in my sig.
These chips put out tiny amounts of power in transmit mode, maybe 10-30 milliwatts or so. The only phones I have that transmit have to have their headset cable antenna wrapped around the receiver antenna to get anything resembling decent quality.
So I'd call the transmit radius a few centimetres at most. Little wonder then, perhaps, why so few Android devices support transmit.
Hi,
I'm trying to use an Arduino Mega ADK to connect to Android devices using the Android Open Accessory Protocol.
When I connect the Arduino to an Onda tablet using an OTG cable, it detects the Arduino and asks to install the app.
If however, I connect it to a Samsung S3, Galaxy Note II or Galaxy Note 8 nothing happens.
To make sure it wasn't just an issue with the Arduino side, I also implemented it using C# on a .NET MF chip instead of Arduino.
The results are the same, the Onda tablet detects the device, the Samsung devices do not.
Does anybody know if this is a restriction imposed by Samsung for some reason (sounds silly) and is
there a way around it?
Just as a reference, the code I'm using on the Arduino board is just a sample from a wrox book:
Code:
#include <AndroidAccessory.h>
#include <ch9.h>
#include <Max3421e.h>
#include <Max3421e_constants.h>
#include <UsbHost.h>
char application [] = "wrox_temperature_sensor";
char accessory [] = "wrox_temperature_sensor";
char company [] = "Wiley";
char versionNbr[] = "1.0";
char serialNbr[] = "1";
char url[] = "the url to the apk here but I cannot post links in the forum"
int sensorPin = 0;
long timer = millis();
AndroidAccessory usb(company, application, accessory, versionNbr, url,serialNbr);
void setup()
{
usb.begin();
}
void loop()
{
if (usb.isConnected())
{
if( millis() - timer > 10 )
{
int val = analogRead( sensorPin );
float voltage = (val * 5.0) / 1024.0;
float tempCelcius = voltage * 100;
float tempKelvin = tempCelcius + 273.15;
byte * b = (byte *) &tempKelvin;
usb.write(b, 4);
timer = millis();
}
}
}
I should also note the Samsung devices to have a file '/etc/permissions/android.hardware.usb.accessory.xml'
to indicate the device supports Accessory mode:
Code:
<permissions>
<feature name="android.hardware.usb.accessory" />
<library name="com.android.future.usb.accessory"
file="/system/framework/com.android.future.usb.accessory.jar" />
</permissions>

same behaviour of Galaxy Note 3
I observe a similar behaviour for Samsung Galaxy Note 3 (Android v4.3) when I try to use it with a custom accessory based on an Arduino DUE.
Then GN3 responds to the initial AOA negotiation messages sent by the sketch running on the Arduino but at last it sistematically fails to switch to the accessory mode; Android asks the user to give the permission to launch the App associated to the accessory but, when launched, it works only in write mode (that is The App sends correctly messages to the accessory) but not in read mode (it doesn't receive notifications of available messages from the accessory.
Of course I verified that the same application do it work correctly on other Android devices, also on a Galaxy S2 with Android v4.1.2 (all devices are not rooted).
I am looking for a solution but the debug process is a bit difficult for me.
I Hope someone can give some hint to solve this problem.
Hi every one,
I am working with Android Open Accessory V1.0 with several Samsung devices and it works perfectly ( S3, S2, NOTE 2, etc.)
I have other technical problems with USB communication and especially with ParcelFileDescriptor becoming NULL when restarting the MainActivity
can any one help me with this issue ?
Reverse VNC Server
VNC server which is aimed to reverse connection (however it supports direct connections too).
Reverse connection means that server connects to client. I.e. VNC viewer should be run in listen mode. This is usefull when device, which screen you are going to send someone, has no public IP address.
For correct work device should be ROOTed
Main reuqirements were:
- reverse connection stability (ability to reconnect at connection lost, none of free VNC servers can do this)
- support most devices (it uses frame buffer as screen get method; input events implemented via input tool execution, so it should work everywhere)
Installation:
- install apk file from attachment. E.g.
adb install ReverseVNCServer.apk
Execution:
You can start VNC server via GUI or via command line.
Starting from command line:
Command line parameters (optional):
-c Reverse connection host and port
-t tries : Number of tries for reverse connection
-r : reconnect on reverse connections lost
-p localport : Local port for incoming connections. Default if 5901
-h : print this help
-v : view only
-s scale : scale percent (default is 100)
-d framebuffer device (default is /dev/graphics/fb0)
-z zoom : specify zoom of cursor coordinates in precents
E.g.
adb shell /data/data/org.arcsinx.reversevncserver/lib/libreversevncserver.so -c 192.168.1.34:5500 -r -p 5901
Hotkeys from VNC viewer:
- left => left
- right => right
- down => down
- up => up
- backspace => back
- ESC => back
- Home => Home
- PgUp => Menu
- F3 => Search
- F10 => Power
- F11 => Disconnect
- F12 => Shutdown application
Sources:
- Location
github.com/ArcsinX/ReverseVNCServer
- How to build
1) run ndk-build in top directory of checked out sources.
2) run update_libs.sh script
3) Import top of sources directory as android application project in Eclipse
4) Run from Eclipse to create apk file in bin directory
TODO:
- VNC password protection
- GUI improve (needed to make it not so ugly)

Thanks for reply.
I have changed a bit frame buffer device initialization and added more info ouput before mmap() call.
Could you try to run it one more time and one more time provide output before mmap failure?
Application updated:
- Added scaling
- Added view only mode
- Built-in NoVNC (for connections via browser)
- Some GUI improvements: landscape view, connection strings

I reproduced this problem: set fb_size to yours and try mmap with it. It seems mmap fails for thus big values (in case of high resolution).
So I replaced mmap call with malloc + read. Now it should work. Updated version attached in the first post.

This is very strange, that "No such device" error appears at try to read framebuffer device (not at opening it).
You can try command
adb pull /dev/graphics/fb0
This command should create local file fb0. If this command fails then something wrong with framebuffer device:
- maybe on Note 3 framebuffer devices do not work
- maybe some other device should be used. You can list all you graphics devices with command adb shell ls /dev/graphics/
On my device I have two framebuffer devices: fb0 (for touchscreen) and fb1 (for HDMI connected displays)
If you able to find framebuffer device for which adb pull will not fail then you can try to start VNC server with this device passing extra -d option.
E.g. adb shell /data/data/org.arcsinx.reversevncserver/lib/libreversevncserver.so -c 192.168.1.34:5500 -r -p 5901 -d /dev/graphics/fb1
Anyway I am going to implement one more screen capture mode (Surface Flinger). Maybe then It will work on your device too.

I doubt reading the framebuffer works on stock 4.4 Samsung Galaxy Note 3 ROM. Tried all of the devices and did some google research without any positive result.
Anyway. keep up the great work as a reliable RVNC Service was just missing on Android! :good:

Hi. Can you say what exact message appears? I mean that perror() call prints out error description.
Also can you provide output of the following command on your device?
Code:
ls /dev/graphics/
E.g. on your pc to which your device connected
Code:
adb shell ls /dev/graphics/
P.S.
Btw, I have not update apk for sometime (I am going to update APK today.)
Update:
I have updated APK in the first post, try it first.

Hi there, I know this is an old thread but I am just discovering it now. I tried to look up the github link but it doesn't appear that it's available anymore. Do you know if the source code is published anywhere right now? Thank you!
Backstory: I have an old (2008?) vizio VA22L FHDTV10T. 1920x1080 60hz panel. I want to connect it to my pc, but if I use anything other than the VGA port (eg HDMI) it overscans and applies all this crap to the image. It's clear and crisp and beautiful if I use VGA (tested with old VGA gpu), but alas, my pc doesn't have a VGA output. (Yes I tried all the settings, no they don't fix it. Yes, I tried adjusting the graphics driver settings, no they haven't fixed it without being a PITA every time I turn the tv off.)
On to the important stuff: I can access the tv with a serial connection via "Service port" and can see a Das U-boot boot sequence and issue commands. I just don't know linux and can't get anywhere past the help menus. If someone could guide me on modifying this thing I'd be rather grateful!
For starters, here's the output when I first turn it on whilst pc is plugged in via VGA, wait for it to finish booting, and press enter.

Mmm, so right after posting, I figured out that I had to change directory to one of the commands listed in the first help in order to issue commands from the sub-help of each one instead of using them as arguments. EG: cd pmx [enter] pattern 1 [enter] would turn on the test pattern instead of pmx pattern or pmx pattern 1 or pmx -p and other such variants. There's probably a guide for this out there somewhere but most of my searches just turned up historical info on German submarines... Oh, and this thread which is kinda along the same lines: https://forum.xda-developers.com/android/software/rooting-mediatek-based-linux-smart-tv-t3150281
I guess now I just have to find which setting(s) fix my apparent problem, then I'll need to append the firmware, assuming I can't do it from the serial console. And that'll be the part I definitely need help with.
Maybe I can just use commands to do this, but I don't know what most of this is, and my searches aren't yielding much... That said, I can run the commands and post back the results since I don't expect anyone to have this same model.

Wake times are also over 10 seconds, and the bright blue when there's no signal is rather jarring, so I suppose I'll need to extract and modify the firmware. Can anybody help with this?
Bump I s'pose. Still stuck, so for now I'm working on other things till I find someone who can help with this. I'd rather not drop $25 on a chinese basic mainboard for the panel or whatever I can get away with paying for a dubious identical-looking universal mainboard.
So I'm at it again trying to make this work. Glad I posted everything I did since I totally forgot how to work this thing... Still need help. I'm trying to dump the firmware with u boot so I can try to modify and reupload it with my custom values.
I also have this TV and would like to disable overscan. How should I connect my PC to one of its service ports? It has two service ports: a type A USB port and some port that I think is called 'ISP' or something like that. For what it's worth, I already have several USB to RS232 adapters (male USB type A on one end of the cable, male RS232 on the other end of the cable), but this TV doesn't have an RS232 port. I've already downloaded a third-party PuTTy app ("PuTTy (Unofficial)", if I recall correctly, from the Microsoft Store).
Edit: Made a correction.
I also have an adapter that is USB type B on both ends. It is called "SharkPort", IIRC. It was designed for connecting a PC to a PlayStation 2 to transfer PS2 game save files. It *might* be a USB host-to-host adapter. It is probably USB 1.0 or 1.1.
Big love for this thread even though I'm probably useless at the moment.
I'm ambitiously following some of your footsteps to tinker with my all-but-entirely defunct Vizio E3D420VX.
Curious how this story played out though; it looks like it relies more on TV knowledge than Linux-- these settings are pretty dense.
