CC2642R: How to debug FaultISR

Nithin Tom

Part Number: CC2642R

How can we debug FaultISR in cc26xx device family?

I want to learn on this. On what conditions this FaultISR get invoked ?
Is there any particular registers to read for that ?
Is there any materials that explains FaultISR ?

Thanks!

Hi Nithin,

Thank you for reaching us,

The file you are searching concerning faultISR is located on the source code of your sdk : source > ti > device > cc13x2_cc26x2 > startup_files.

However we don't have any documentation for the moment on faultISR, I took the feedback in consideration.

Hope this will help a little,

Regards,

Hi Guillaume,

Can we use spma043.pdf for this purpose?
Or any particular register read that indicate which type of error(e.g., null pointer access) caused this hard fault ?

Thanks!

Hi Nithin,

I don't think both are compatible as spma043 is for Stellaris MCUs.

However you can have a look to the TRM of CC2642, the ISRNUM register is related to bus fault status and maybe will help.
