MPC555 CENSOR Bits problem

[Mr32Bit]

Hi, I'm new to this forum e to PowerPC so I'm here to ask help to some MPC Guru.

My problem is that making some test on my board with MPC555 I have put CENSOR == 0b00, and now with my BDM P&E Micro I'm not more able to erase or program the internal flash, if I try to read the flash all is 0x3FFFFFFF. How can I put CENSOR = 0b01 or 0b10 ? I think this will resolve my problem. If I read the register at address 0x2FC800 and 0x2FC840 the value is 0x80FF00FF.so CENSOR is really 0b00.

Someone has a compatible BDM file for P&E Micro Multilink BDM that can change CENSOR?

Best regards to everyone

Gian

These drivers contain ChangeCensor function:

The function can be executed from RAM.
