Usually when we'r directly working on device, RAM_CONSOLE is better choice.
To setup this we have a ram_console driver at drivers/staging/android path [enable it] & you just create a platform device entry in BSP code. Once you have any crash/hang happening on your device, for next the reboot try to dump the log from /proc/last_kmsg [where you can get the previous crash log]...debug it Regards, Jagan.
