TI ICS android is hanging in AM335X

Hi Anandu,

Can you post the logcat and dmesg output?

Arun

Hi Arun ,

Thanks for the reply...!

Please find the attached pdf for debug messages and logcat messages.  Once the crash happens the root will be accessible through UART . At the same time ADB and none of the peripheral will respond.

Looks like there were some audio errors seen on the logcat. What is the application you are running? Is this hang reproducible always?

Hi Arun, 

  Thanks for the response..

When crash happening I am not running any application on the board. This crash is happening always . It is not happening at regular intervals, its varying, Most of the time it will happen in half an hour. Eventhough we are using a custom board the only major diffrence between  the Sitara EVM and ours is we have removed the Ethernet. When the crash happens sometimes the touch screen responds  other peripherals wont work some times both wont work.

The kernel is responding so is there any way to debug this issue through kernel. I am using the same file system I downloaded for Sitara EVM from TI website. Even I tried a

custom build file system also then also the same issues. Do I have to do something with the hardware? Please help me out in solving this Issue

Hi Anandu,

I went through the debug messages and could not find any error which can cause a hang which you have described.

Can you check "getevent" to see if the touch screen is responding? What is the memory of the custom device? Is the logcat keep running when the hang is occuring?

Regards,

Arun

Hi Arun,

    When the hang happening none of the peripherals(Bluetooth, WiFi, USB ) are working (But sometimes I have seen that touch screen is working but other peripherals wont work ). ADB  is  not responding when hang  happening , So logcat messages are not coming. The memory of the custom board is same as the  sitara Evaluation board memory(256MB).

Hi Anandu,

Can you run "procrank" to see the available free memory on the system?

Dear Arun,

   Please find the result of memory analysis by procrank

As per the result  free memory available it is only 18500K is it OK for the normal working of the android.
