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);

Regards,

Daniel

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.
