how to decode debug dump under TI-RTOS

Hi Sergio,

The exception dump that you see on the console is a dump of the general purpose registers (r0-r14), program counter and various fault status registers that encode the type of the exception and in some cases the address of the instruction causing the exception.

The SYS/BIOS (TI-RTOS kernel) exception handler decodes some of the fault status registers for you and prints the type of exception. In your case, the exception handler determined the cause was an Immediate bus fault accessing address 0x6820219e and the instruction that caused the exception was at 0x0001a7cc (PC).

The PC, LR and SP register values in the exception dump can be used to get the callstack at the time the exception occurred and should be very helpful in debugging the problem. Checkout the below wiki page for more info on how to do this:

Coming to the question about the module and task instance names, the module and instance names are not shown in the exception dump because some of the strings are not being loaded to the target. This is usually recommended to save space. You probably have the below code somewhere in your application's *.cfg file. Please change it as suggested below:

var Text = xdc.useModule('xdc.runtime.Text');

/* 
 * Uncomment this line to keep Error, Assert, and Log strings from being
 * loaded on the target.  These strings are placed in the .const section.
 * Setting this parameter to false will save space in the .const section.
 * Error, Assert and Log message will print raw ids and args instead of
 * a formatted message.
 */
Text.isLoaded = false; <-------------- Comment this out or change to true

Hope this helps.

Best,

Ashish
