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
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:
If you use it please read carefully all instructions.
