Just looking for input on the fastest ROM out there. I've only tried one myself - MightyROM - and I love it, but I do get a frustrating amount of lag on the phone and tends to use alot of RAM.
What are your lightning fast fav's?
I really liked the bare naked ROM series but that was discontinued, hands down it was the fastest ROM i've ever tried. Right now i honestly cant find any noticable difference between most ROMS anymore in terms of speed. Although I havnt tried grooveROM, I just overclock all my ROMS now and any manila 2.5 ROM is almost always the same speed.
I have used alot of roms but so far the one I have kept the longest is the neodium rom. Get the one that says "Sept 15 Neo-CHT-2018 (SYS 21916)". Manila runs so smooth, it has CHT, & I have never had any lock ups. I haven't soft reset my phone in about 1 month (which is when I got the rom). That says it all to me.
Here is the link at PPCGeeks.
Thanks for the info. I think I'll give that other rom a try. I hadn't considered overclocking but I'll start a seach for that and see how thats done too. Thanks!
Loaded neodium rom last night and so far really like it. It really does seem faster! Have you tried the other versions of it that are available - Plutonium?
Mine is 21057 core WM 6.1 with Sense 2.1919,that is freaking fast enough,and always stay on around 50% RAM,that's why I don't like any WM 6.5 with Sense 2.5 till now
Please people. If you are gonna say that any rom is the "fastest", please post benchmarks to prove it.

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.

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.

Where do I find utilities to dump/decode/encode BTS files ?

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.
In case you need to know how to poll GPIO values from photon, here is a small how-to:
First of all, read THIS:
http://htc-linux.org/wiki/index.php?title=HaRET_Documentation#Polling_GPIOs
To disable automatic launch of Android when you execute HarET, you must rename your file "startup.txt" to "default.txt"
The issue is, when you poll for GPIOs with Haret, you got a numeric value that does not match with GPIOs in Linux (board-photon.h)
To translate "HarET GPIO" to "Linux GPIO", here is a trick:
Haret gives you this line:
009.179 GPIOS 92f00808(117)=300100

Take the number between parenthesis: 117
Divide it by 32:
117/32 = 3, rest = 21
3 is the GPIO bank:
bank0 = 0 to 15
bank1 = 16 to 42
bank2 = 43 to 67
bank3 = 68 to 94
bank4 = 95 to 106
bank5 = 107 to 121
in our example, bank3 starts at value 68, so the Linux GPIO is:
68 + 21(rest of division) = 89
note: if the bank number is higher than 5, it means it is the following bank, or the one after. in this case, remove 6 or 12 to the bank number so you have a value between 0 and 5, and do the normal computation.
I must to say THANK YOU!
hmm I not understand (rest) I got 3,65625 (bank 3, rest 65626)

lol
on my sample, another way to say it:
117/32 = (3 * 32) + 21
or:
117/32 = 3.65625, you take the 3, rest 0.65625 * 32 = 21
in your case:
303/32 = 9.78125, you take the 9, rest 0.78125 * 32 = 25
9 is too big, remove 6 => it's bank3
bank3 = 68+25 = 93
in board-photon.h, it is defined like:
LIBERTY_GPIO_LS_EN 93
in the code (board-photon.c) it seems it's the GPIO for power
thanks, understand now \o/
Hi,
I got slightly different format for GPIOS.
Please refer to here

How to I convert them?
Thanks in advance
I just got the KT747 kernel on CM10 stable. I might want to under volt because battery life is sucky for some reason . I want to know how I can get the best battery life of this phone with this kernel. Any suggestions?
Depends on which cpu pvs you have. There is slow/nominal/fast, fast needs a lot less voltage where slow needs a lot more and thats where the stock kernel voltages default to (slow). Im running these voltages fine and just havent dropped em anymore cause I keep forgetting to, but i plan on dropping much more if I can....
Code:
clock - mv
1512 - 1130
1458 - 1115
1404 - 1115
1350 - 1105
1296 - 1105
1242 - 1080
1188 - 1075
1134 - 1060
1080 - 1055
1026 - 1005
972 - 1000
918 - 980
864 - 980
810 - 945
756 - 945
702 - 900
648 - 895
594 - 875
540 - 870
486 - 850
384 - 820
192 - 810
144 - 800
96 - 775
Keep in mind I have a fast pvs cpu so depending on what you have these may be to low for you.
Per Imoseyon's which would carry over to ktoonsez kernel fine....

The only way I know to check which cpu you have is to flash leankernel and from a terminal do "dmesg | grep ACPU"
When I do dmesg | grep ACPU in terminal emulator it says " Operation not permitted"
EDIT: I tried doing in I superuser mode and it gave nothing. Screenshots are below.
Window 1: http://imgur.com/kYNi9 No super user

Says that its nominal
don't understand the recommended voltages
I see the recommended voltages set by imoseyon but when I only go into SETCPU and go the voltages tab I can only set ONE voltage for each line not a range like in imoseyon's post. Do I set that that one line to the max or min? PLEASE HELP THIS NOOB!
384000,900000 -----------------> This is what I mean. I can click on this line but it only allows me to set it to one number (not a range).

Those arent ranges those are cpu speed and voltages. i.e. 1900000,1300000 is 1.9ghz @ 1300mv
