MPC5744P Censorship

Dear Sir,


I have modified the MPC5744P DCF to make the MCU in censored mode.

See attached picture for the dump of UTest Flash memory.

I changed the password to be 66666666 33333333.

And change the censorship control word from 55AA to 55BB.

Do you see any problem here?


After reset (sys.up in Lauterbach), the MCU JTAG is locked.

I tried to access with "sys.option keycode 0x6666666633333333"

or "sys.option keycode 0x3333333366666666"

But still not able to access the MCU.

Do you have any suggestions?
