I have some projects that were left inadvertently with some function calls that write 0x00 bytes into the data EEPROM. They work properly. I have tested it.I detected the problem on a prototype board with an old sample of STM32L152C6T6 and this made ...

OK. Thanks a lot

Indeed it seems that the "A" parts don't suffer of this problem. But it is not documented in the manual... Can we trust that "A" parts don't show this problem?Thanks

NOT ALL PARTS ARE DOING THE SAME..... FORTUNATELY!!!!I HAVE PRODUCTS SELLING IN THOUSANDS AND "APPARENTLY" RUNNING WELL WITH THIS HIDDEN PROBLEM ON BOARD...

In the following code:void write_stm32_eeprom(dword addr, byte dato) {byte *p; if ((addr < START_EEPROM) || (addr > END_EEPROM)) return; p = (byte *)addr; if ((*p) != dato) { //Enable write access to EEPROM FLASH->PEKEYR = FLASH_PEKEY1; FLASH...

Good morningThank you for replying.This is the page of the RM I’m talking about:The device I’m using is a CAT.1 (STM32L151C6T6 or STM32L152C6T6)
