S12VR64 write flash

Hello there. I use S12VR64 chip, I need to store a lot of data, eeprom is not enough to use. I want to store data in flash. I used the official NXP library to write to the flash address 0x30000, but in fact the corresponding address does not show the value I wrote.

Hi,

I recommend you look at the AN4448 SW. There is a flash demo example code for the S12VR64:

I hope it helps you.

Best regards,

Diana
