CC1312R: Main_excHandler firing but can't determine why.

Hi,

My application is built on Simplelink SDK V5.40 and based on the Collector example.

I am using IAR, but am trying to debug in CCS to see if I'm able to get more information regarding the Main_excHandler() running. I cannot get ROV working as I think it needs rta and uia xml files which don't seem to be produced in my version of SDK as there is no configPkg produced. I think this is fixed for the next SDK V6.20. Correct me if I'm wrong.

Do you know how I can get any more information about why Main_excHandler() is running? 

I've attached a screenshot showing the Main_excHandler() parameters but they only refer to the calling of Main_excHandler() itself rather than a useful RTOS stack dump.

My feeling is that the error is due to SPI activity, but that's just a guess.

Thanks,

Andy

    Hi Andrew,

    As you say there is a known issue when using TI-RTOS7 + ROV which has been fixed in SDK 6.10. It would be very useful to get the HWI exception information from ROV in order to see what's going on with your device.

    You can see some more information in main.c and your TI RTOS cfg file.

    Cheers,
