Copy code from Flash to RAM and run s32K342

Hello,

I am currently working with the S32K342 microcontroller and S32DS v3.5 , SDK v4.0.0, and I have a requirement that during startup the complete program should be copied from flash to RAM . so it will execute fully from RAM.

Probably i need to modify some sections on linker script, also modify the startup code, but im not very familair with this device yet. I would appreciate guidance on how to do it.

Best regards.

Hello David,

this is not what im searching for. the example you provided is just for copying 1 function from flash to RAM.

what i want is to copy the complete code during startup from flash and execute it from RAM only.

Best regards.
