Hello

I need some help to understand my problem.

I'm using eeprom emulation V3.1.0 MCD from Application Team and that works fine.

When I reboot I get the PGPERR and PGSERR bits set after a while.

I placed breakpoints on all functions that program or erase the flash, so I'm sure they are not reached.

What else can set these bits ?

P.S. I'm working on STM32F407.

Regards

It setted PGPERR and PGSERR bits but did not raised a HardFault ...

Hi,

you mention V3.1.0 for the EEPROM emulation. Is this a new version? I can't find this on the ST website. I still work with 1.0.0 from 2011, for which I needed to integrate the old SPL Flash driver into my Cube HAL based project.

Regards, Ralph

Hi christopher.ralph,

AN3969 with associated firmware (version 1.0.0) has to be used for STM32F40x/41x devices (

).

The version 3.1.0 is the one to be used for STM32101/103 devices (
