Eeprom emulation cannot find ERASED_PAGE when all pages are full

Hi,I'm porting "eeprom emulation" into STM32L476RG. It is based on "en.x-cube-eeprom".I set GUARD_PAGES_NUMBER 4When all eeprom pages are full, then it can't go forward.EE_WriteVariable32bits() -> WriteVariable() -> EE_PAGE_FULL -> PagesTransfer() ->...

How much is the minimum number of pages used with EEPROM emulation(AN4894) techniques?

I'm implementing eeprom emulation with the STM32G0 series microprocessor. I am using the AN4894 Application note and the X-CUBE-EEPROM(4.0.0) software, but I have encountered a problem.Let me explain how I use it first. I'm recording 128 values that ...
