Read more about optimize options in this link, Set CONFIG_NO_OPTIMIZATIONS=y to turn of most of the optimizations.

If you have more questions, please open a new case and present your problem there.

Best regards,

Hello,

What does it mean to compile the application without any optimization?How to do that? Even I am getting the hard fault in UART.

I'm sorry for the late reply. Try compiling the application without any optimization (if you aren't doing it already) and see if the call stack is valid then.

Best regards,

Simon

I'm thinking now that the Stack contents listed are not valid, as the SP is at the top of the interrupt stack, and what I am looking at are variables in the data ram.

So there doesn't appear to be any context available for this fault.

I also note that using the debugger, a similar fault sometimes occurs when resetting/restarting.

Also from the SPM zephyr.map file, which is consistent with the Stack Pointers RAM space
