How to Disable BDM After First Flashing on MPC PowerPC MCU

[imsujith3]

I am using BDM for flashing my MPC (PowerPC) microcontroller, but I need to disable BDM communication after the first programming to prevent further access. Is there a way to block BDM from the software side, such as modifying security settings or configuring flash protection registers? Any suggestions or best practices would be appreciated.

Hi @imsujith3 

I think this question has been already answered here:

There's no such feature.
