Determining source of "reset"

Richard Phillips

Hello all,

I have a simple C++ application flashed to my device to operate the UART - every time I send a char from an external source, the device appears to reset - specifically, the disassembly window leaps to 0xfffffffe. The call stack shows - I'm speculating that perhaps I need to be handling an interrupt that isn't currently handled?

How can I trace back to see which (if any) interrupt has fired (and maybe not been handled)?

Regards, Richard.

    @Richard: I'm not very familiar with IAR, I would suggest you to isolate the issue, maybe creating a project to test just the UART module. Note that we provided an example on UART in the SDKv8.x and there is an IAR project for UART that you can test.

    If it doesn't help, I would suggest you to post a case in our support portal (Mypage section in our website), it's private portal where you can send confidential information/code.
