Jtag password

[abdelrhman]

Hi all,

I'm wondering how to set a password for the Jtag module of MPC5744p to prevent neither flashing nor reading the flash memory sectors?
secondly,
how to use these configurations to flash a new firmware, knowing that I'm using s32 design studio for power architecture ?

Thanks in advance

Hello,

I'm wondering how to set a password for the Jtag module of MPC5744p to prevent neither flashing nor reading the flash memory sectors?

You can refer for details in reference manual:

56.4.7.1 Securing the microcontroller

I have posted a thread about censorship via JTAG with Lauterbach:

for PE:

The password checking procedure is part of PE Micro eclipse plugin. You can try to ask on PE Micro support.

Best regards,

Peter
