Hello,The chip that I use is MPC5566. For this chip, how to set the encryption mechanism, prevent piracy from accessing the flash from the JTAG debug interface, read the software code? I Query manual does not find related encryption methods.Thank you very much.
Respectly
Hi,
There’s no encryption on this device, there’s only censhorship feature which prevents unauthorized access via JTAG.
You can take a look at this application note:
https://www.nxp.com/docs/en/application-note/AN3787.pdf
https://www.nxp.com/docs/en/application-note-software/AN3787SW.zip
And then at this SW example:
https://community.nxp.com/t5/MPC5xxx-Knowledge-Base/Example-MPC5644A-Censorship-CW210/ta-p/1105016
It was written for MPC5644A but it’s pretty much the same for MPC5566 in terms of censhorship.
Regards,
Lukas
