S32K148 EEPROM Programming process

Dear Sir:

We are a third-party programmer manufacturer and want to program S32K148 EEPROM (0x14000000~0x14000FFF).

Can you provide programming documents (including programming steps, processes, commands... and other information) for our reference?

Thanks

Hi @gary_yang,

The main differences between writting to SRAM and FlexRAM (in EEE mode) are:

  • The EEE can be written once EEERDY = 1, which is set either automatically after system reset exit (which inludes the copy-down process) or after the FTFC SetFlexRAM Function command.

  • Any write to EEE clears the FTFC CCIF flag, and any subsequent write can take place only once CCIF is set again.
