Eeprom initialization

972276616 — Wed, 02 Dec 2020 09:54:27 GMT

Hello!
Initialization sometimes failed when I used EEPROM of S32K116, but after investigating and testing, I found that in debug mode, initialization could be successfully initialized if the break point stuck in the call initialization function.However, running directly to the end of initialization sometimes returns a failure.Please help me with this problem.
EEPROM initialization code is attached.
Thank you. Best wishes

Hello,

Please make sure the function that launches the FTFC Program partition command is in SRAM.

See the below threads.

Hi,Daniel

Thank you very much for your help.Per your instructions, let me just put my EEPROM initialization function in RAM and execute it, as shown in the picture, shall I prefix the function with ___ (section(".code_ram"))?

Hi,Daniel Thank you for your answer. I have one more question to ask you. When initialized in RAM, an EEPROM erases all Flash data. Regards, Zhengyu
