Dear Mr./Mrs,

 

I work on MPC777C. When I have a variable as unsigned int, I can program flash to write this variable into easily. However I would like
to learn whether I can program array flash to write 1000 byte in one time by using flash peripheral hardware or not? I am looking forward your answers.

Best regards.

If you don’t want to use NXP driver (what I would recommend anyway), you may write your own functions as flash simple programming example we have sometimes as following for instance:

https://community.nxp.com/docs/DOC-101849

 

Specifically for MPC5777C we don’t have prepared such one (standard software drivers are recommended) but you may see for instance following where I used simple programming method for injecting of 2b ECC error:

Program data per 64-bit in the loop.
