Dear All,

I'm interested to know if anyone knows a way of writing to CPU registers using MACROs in IAR EW C-Spy Debugger and ST-LINK.

I've read the documentation and searched around for an answer. Seems such a simple task.

Thanks,

Kirem

Presumably something like R1=0x11223344; doesn't work?

Hi Clive,

I was looking for a way to change the program counter in the execUserReset() {} macro.

There are the obvious memory read and write macros but I can't see anything for registers. I don't know if this is a limitation of the st-link API. There are some additional macros for the j-link interface that aren't supported on the st-link.

Thanks, Kirem

Hi Clive,

Just to add that memory accesses are through inbuilt macros. I will check if your suggestion works.

Thanks, Kirem
