Hi,
I'm working MPC5565 Controller.The Censorship Control word at address FFFDEo got erased accidently.
Now the lauterbach controller is not giving me acess to flash/erase my code.Bus error is generated if we try to write to any area in flash using data.set command.Anyone have an idea how to enable the flash again.

It is very inportant that when the shadow block (where the cesorship control word resides) is erased that it be reprogrammed with llegal censorship values before the device gets reset.

once the censorship control word is erased, if the device is reset, then the flash is never accessible again. there is no way to recover the flash.
