CCS/PROCESSOR-SDK-AM437X: Exception logging

Part Number: PROCESSOR-SDK-AM437X

Tool/software: Code Composer Studio

Dear support,

Is in sysbios/RTOS any module or functionality which can be used for exception logging. Modul should store exception info. somewhere in RAM. Information should be readable after reboot.

For example:

- application is running (sysbios)...
- Exception occurred.
- Exception text with SP, PC, task handler etc. is stored in ram
- system is reboot
- application is running (sysbios)...
- Exception text can be read and forward with TCP, UDP, serial, etc.

Any idea?

Marko,

TI RTOS does support exception logging and also supports exception hooks to take action when an exception occurs. Currently there is also an built in option to print the exception dump to CCS console so this exception control does reside in RAM. However, we don`t provide any sample code to retain the exception context through reboot so any mechanism to send this over ethernet or to store to Flash needs to be done by application developers.

The full details regarding exception module in TI RTOS for ARM cores can be found here:

Here is additional training that our TI RTOS team has created for exception handling:

Please review the exceptions and the Exception Hook and let us know if this suffices for implementation of the usecase.

Rahul
