[GUIDE] schematics and troubleshooting guide - Samsung Galaxy SL i9003

Below is the link for i9003 schematics and troubleshooting guide! hope this is helpfull in adding usb otg and tv out feature to i9003.
4shared.com/file/YzPnzZtQ/Samsung_i9003_Schematics__Trou.html
I have searched the pdf but could not find anything related to tv out....only thing I found was on page 11, in u301 ic there was a reference video...and it seems to be not connected
In omap application processor there is supposed to be tvout1 and tvout2 which I cant find in the schematics.
I think this will be much more usefull for otg project...now we will get clue as to which port needs to be activated to get power!

Thanx buddy...i love usb otg feature. But right now CM7 project is more important to all of us. Once we succeed in stable cm7 then we can think about this.

[Q] Android port to Sony Mylo 2

Anyone want to help me port a basic android (1.0 etc.) to the Mylo com-2? I've looked everywhere to see if anyone has completed this yet, but i haven't had any luck. If anyone knows anything about this or wants to help reply please!
I'm also porting it onto MYLO COM-2
To start you gotta find what version is best suited for mylo com-2 to be more exact you need to find a version of android to port that has similar hardware to mylo com-2 and of course edit the drivers,or you can compile it from source but then you will need to add your own drivers for the hardware of the mylo.
I'm working on to it (you gotta port every driver mylo hardware has to a specific version of android and test it) as i did the teardown of the mylo com-2 it will be quite difficult to port the drivers but i have mylo 2 disassembled and listed the hardware as shown below
You can help by compiling drivers for each hardwares using the source code (can be found on Sonys website) and using the mylo 2 table as shown above
Thanks

The chart doesnt seem to be showing on my computer.
I found the Source Codes through sony.
I was working on this as well. I think the big issue is going to getting access to the bootloader. I have been wondering if sony is using a jig stick or diagnostic boot mode for the mylo like the psp has. I have been trying to see if there is a way into some kind of bootloader menu but haven't found anything yet. I have also been looking at reverse engineering the update.bin files but to no avail. I do know quite a bit about the hardware onboard. I know it will support usb host.
Android on Mylo 2?
Hi,
I want to ask at what stage the project is located. I have the Mylo 2 and I am interested in having it on Android or other mobile system. If it is already possible on the Mylo 2 have the android or something else I'll be happy with instructions on how to get there.
Thank you for your reply.
Android on Mylo 2?
Is there anyone who can advise you on the question in the last post?
Zorbon, im not sure of the progress, people say they have hardware info, but i never see any.
Nelson, can i see the info you have on the hardware?
I think we should get this project moving.

[Q] USB Port Access

Hello there dear Android devs!
I have a question about the USB port.
Do any of you have any information whether it's possible to use the USB port manually with an app with Android? I have an idea that needs access to a hardware interface that needs to be connected directly to the Android device..
I might be able to use the bluetooth connection, but that would involve a lot more hardware development, and I'd rather avoid that.
So my question is, do you know any way for an app to use the Mini USB port with an external hardware interface?
Hope you have some good news
//Enslave
Edit: If you have any information if this would be possible on WP7 or iPhone, I'd appreciate hints to that too, but I'd rather use Android to be honest
Sorry to bump this, but surely someone must have some information?
I really wanna get this app off the ground! And it's gonna be something really really cool when it's done.. If it's possible that is ^^

[Q] How to communicate with custom made hw board?

Hi Xda developers,
I might get involved in project during internship, where they want me to find way how to connect android device to custom made proprietary radio transmitter-receiver board without bluetooth or wifi, so it has to be direct wired connection.
This radio transmitter-receiver board has its own microchips and firmware so all low level work and functions will be done in this board alone.
Does anyone has idea how this could be done? is it possible to write some drivers (probably C) to communicate with this board over micro usb port present in all android devices? And than how could be data received over radio used in basic java-android application installed on device? (could this be done with use of a binary/text file as a link between these two programs?)
Thanks in advance
If nobody knows or has time to answer my questions, please give me some tips where to start searching for answers (websites, books, magazines .... )
Is it essential to learn Linux architecture properly before modifying anything in android?

Anyone know about USB Dev?

Hi,
Android Dev Noob and just looking at the SDK I have this question which probably someone will be able to tell be straight away.
I want to relay USB Host port data to a USB accessory port.
I am looking at the USB Host APIs >= Andriod 3.1
What I want to do is be able to relay the keyboard, mouse and touchscreen that I have connected on the host port and relay that to the OTG.
So here is my noob questions before I waste loads of time.
1... Is it possible to create device manifests on the fly.
I was thinking I could just make devices connected on the host appear as if they are on the accessory port.
If not then I guess I could create some default manifests and pick the most relevant.
2... This is hardware related but many tablets and android boxes have separate usb host & otg ports?
It is possible to have a host and accessory going at the same time.
This might makes things a little easier as the rationale is that I have a windows 8 machine and an RK3288 android box and I want to share the keyboard, mouse and touchscreen.
Video is easy as I can just swap the input between pc & hdmi.
I was thinking if I plugged all my devices into android I could just have a hot Key to redirect to windows 8 or don't capture and use devices on android.
I thought it might be a much simpler way without network needs and have read there are gesture problems with KVM products such as Synergy.
What do you think is it possible, does anyone know if this has already been done and there is an app?
Also if you have any better ideas or some pointers where to start all will be welcome.
Many Thanks
Stuart

help with developing small app for usb/serial/relay control

Hello i just signed up to forum so i couldnt put this in the appropriate forum but my question is
I would like to make a small app to control a usb to serial adapter that has 4 relays built in that i would like to switch on and off. i was thinking usb to rs232 adapter i saw ftdi has an android samples and hardware that may be suitable i also saw several usb serial adapters on fleabay i couldnt put links to any of it being new and other places but im not sure what would be best suited for the task. i have eclipse running along with android studio but im no programmer by any stretch of the word im able to mostly edit code or do things along that line. I did use the app inventer tool on mit website to make a concept apk but thats as far as i got so far. anyone offering any info on where to start on the hardware side and also im not sure of what to use as far as a designer/programmer/compiler the only programming i have done has been visually so something along those lines would be great.
the concept app was 4 on off sliders one for each relay
any advice or help appreciated thanks
Ryan
I wanted to add some more info my device is a in the family of AN-21 U 4.2.2 car stereo dvd nav unit devices from china i am not rooted but already have one ftdi usb serial device installed and working(obd interface) so my feeling is im all set with the ftdi drivers.
moderator can this be moved to appropriate forum? or do I need to make 10 posts to be able to make one there myself?
