Trying to write PC(Program Counter ) & SP(Stack Pointer) using SWD

[Nivas Bathirappan]

Hi,

I have developed an SWD working code which read-write the Flash Memory and RAM which is working very good.

Now I have a problem in I need to write start address in PC via SWD.

I need to know what is the address of  Registers for Nordic nrf52832.

I need SP & PC address through which I can read & write.

Hi,

What program are you using for this?

You can do this with nrfjprog --readregs and --run [--pc <pc_addr> --sp <sp_addr>] commands. Can also be done in python, using pynrfjprog.
