During under voltage and Network sleep conditions, we are writing the Data flash data(1Kb) , this makes the ECU Data flash corruption and reflash is required to work ECU normally.

 

I am using Controller MPC5604S and clock frequency 32 Mhz and 

EEPROM Emulation Software Driver EEE_Driver_v1.3.0, for C55/C90FL/C90LC Flash Modules from NXP.

 

 

Is the corruption caused by write incomplete in under voltage ?

what is the timing requirement for this driver to write on low voltage?

Is it advisable to update NVM during shutdown with this EEE_driver?
