Hi, friend

Maybe you are not close interrupt before operate flash.you can try that close interrupt before erase flash section ,and open interrupt in the end.

Hi,

How did you define the .MyRamCode section?

Please try the default ram section using:

__attribute__ ((section(".code_ram")))   // place the function below into .code_ram section
void EraseAndProgram(void);‍‍

Daniel
