Program Flash Array MPC5777C

[20Sidar04]

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.

Dear David,

I don't want to use driver of nxp. Beacause of this situation, I ask this question.

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.

You can use SSD driver which can be downloaded from out web

MPC5700 C55FG Flash Standard Software Driver (REV 1.1.0)

or you may find it as a part of S32 Design Studio:
