MPC5566 Calibration Flash

Contributor I

Good morning

I need your support in order to help a costumer programming his board.


They want to program a MPC5566 and they sent us a firmware that cover the address from 0x100_0000 to 0x1FF_FFFF.

I’ve read the datasheet and I have seen that that region is called “Calibration Flash” and refers to the internal flash but adding a delay to the access.


I have tried to modify our code and I have written to the your Driver as start address 0x100_0000 but the erase and the flash programming return the error code 0x400.


Is that area programmable or only readable?


If it is programmable, can you tell me which parameters give to the driver?

Best Regards and thank you all

yes, it is read only access. Program/erase operation needs to be addresses over direct non-mirrored addresses.
