Writing to Flash memory kills MCU

sm0khey — Fri, 07 Jun 2024 08:32:55 GMT

Hello! I am trying to save a variable, which a user input, to the flash memory. I am using MC56F82... and the IFsh1 library. I disable the events and then erase the block and then write to the flash, but my MCU keeps dying, i have to restart it and flash it again to get it working. Any ideas on how to do it correctly?

Hi,

This is the flash example code based on CodeWarrior for DSP56800E ver8.x.

Pls refer to it.

Regarding your question, the flash erasing/programming code must be located in flash and copied to p RAM, you have to run the erasing/programming code in RAM to manipulate the flash.

Hope it can help you
