NVM/FEE data not latest

Hi,

If I am writing and reading data to nvm. So as per autosar, when write operation is successful then, FEE should provide latest data while reading 

But in case if writing of data is successful but there is failure in read operation (maybe CRC fail) then data being read is a previous valid data and not the current one. Then how will I know if data being read is latest or previous valid data?

Hello @Sjoshi11,

Normally, to know if data being read is latest or previous valid data, you can dump Flash memory to check data of block status equal to FEE_BLOCK_VALID.

Best regards,

Dan
