Flash Write and Read on MPC5777c

[Shreyas_SK]

Is it possible to read and write to specific blocks of the internal flash memory of MPC5777c(i.e., blocks from 0x00840000 to 0x00FFFFFF)?

If yes can you please share the commands for the same?

I am currently using JTAG to flash and debug the same microcontroller

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:

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.
