AM37x board crashing after a few minutes of video playback

I used the prebuilt Android image for AM37x available here:

http://software-dl.ti.com/dsps/dsps_public_sw/sdo_tii/TI_Android_DevKit/02_00_00/index_FDS.html

Loading an application for local video playback via "adb install xx.apk" and playing the same clip several times causes the board to crash after a while i.e. the picture freezes and "adb logcat" shows no more messages. The only option is to unplug the power supply and reboot.

My booting environment variables are as follows to boot from the SD card:

> setenv bootcmd 'mmc init; fatload mmc 0 0x82000000 uImage; bootm 0x82000000'

> setenv bootargs 'console=ttyS0,115200n8 androidboot.console=ttyS0 mem=256M root=/dev/mmcblk0p2 rw rootfstype=ext3 rootdelay=1 init=/init ip=off mpurate=1000 omap_vout.vid1_static_vrfb_alloc=y'

Booting is somewhat unreliable and does not work when the ethernet cable is not connected. (I do not know the original bootargs or how to restore them to try.)

 

Is there anything I can try or any tool to check what is going on?

(And... Happy New Year!)
