I'm currently using the s32k324 board. I want to create a key here on the board and save the log, but I want to use the nvm area. It works well for the ram area, but how do I use the nvm area?
You can use Emulated EEPROM (FEE) for data storage. In the thread S32K3 EEPROM emulation, my coworker has already shared where you can find the relevant examples and documentation.
