How to relocate all code and data for Zephyr NCS nRF5340 project to RAM?

[denis]

I've added:

zephyr_code_relocate(src/main.c SRAM)

and

CONFIG_CODE_DATA_RELOCATION=y

However, this only relocates by main to RAM.  Vectors, kernel, etc, are still going to flash.

How can I relocate all code and data to RAM?

Hi Heidi,

Thanks!  That "trick" hadn't occurred to me.  That approach seems to get everything in RAM (although the segment is still called FLASH).

Would be nice if there was a project configuration option that located everything in the RAM segment for the future...

End Goal: I'm creating code that runs during manufacturing that tests and programs the PCBA.  This code is loaded into RAM via SWD from a custom production test fixture and then RPC over SWD is used to run the code from the text fixture.

Best,

  Denis
