Hello,

I am curently working on an application generated by the STM32cubeMX software. This application use the folowing HAL library's: tim,adc,dma,uart,gpio... I have to implement an erase and write non volatile memory fonctionality. At first I have used  the HAL_Flash lib but I can write the memory only one time. The application has to write multiple time in the memory with fixed data address.

I have found the AN4061wich is very interesting. I have downloaded the 

STSW-STM32117 exemple but this one doesn't use the HAL library. I can't run both HAL and non-HAL library at the same time.   Is anyone got a solution wich is not to re-code all my application with the non-HAL lib?  Thank's a lot!

    The application has to write multiple time in the memory with fixed data address.

    The EEPROM emulation doesn't make that less of a bad idea. Learn to use and manage the FLASH, it will be far less of a headache. Journal your writes so as to limit the erase cycles.
