How to remap from flash bank 1 to 2.

[BSout.2]

I'm setting the FM_MODE bit in SYSCFG.MEMRMP and I get a hardware fault indicating attempted switch to invalid state.

Hi, when​ swapping between flash bank, you need to execute from Ram and take care of disabling interrupt before. Otherwise instruction fetching can get in trouble..

Thanks for your reply. The code is executing in RAM and is executing in the reset start-up code so interrupts are disabled.

I finally found example code in AN4767. I will be following this example to update my software.
