MPC5604B Censorship password via JTAG

Hello NXP Community,

I have a question regarding the censorship mechanism: when NCPWD0 and

NWPVD1 are succesfully programmed, which istruction has to be loaded in

order to enable the Nexus via JTAG?

In the RM it seems that it could be done even via JTAG:

Can i get access to the CENSOR_CTRL register by using the CENSOR_CTRL

instruction (0x7)?

Thanks

Best regards,

Luca

From debugger low level point of view it is shifting the 64-bit password into the CENSOR_CTRL register (via the JTAG port using the JTAG ENABLE_CENSOR_CTRL instruction) while the device is being held in system reset state.

 

From user point of view most debuggers are capable to enter this password. I am attaching procedure explainig how to enable debug over PPCNEXUS or CodeWarrior 10.6 or Lauterbach TRACE32.

 

Here you may find example code showing how to censor/uncensor the device:

Example MPC5604B Censorship CW210

 

If you use it please read carefully all instructions.
