Hi,

We are trying to flash an existing TC377 Board. However while these trial we ended up locking the MCU (Debugger continuously shows debug port failed). 

Hence, to understand what exactly happened to the mcu. We probed ESR0 pin, which always shows 0. However during start up it tries to pull itself up (image attached). 

Kindly guide, how it is possible to debug the same and what might be the reason for debug port failure.

Hi @NABICHAN ,

Thank you for your interest in Infineon Semiconductor products and for the opportunity to serve you.
According to your statement, it seems that the essential problem is debugging failure, so I was wondering if you can introduce your platform.

BR,

Hi @Neetigya ,

Actually, this kind of information is not my need, I'd like to know what the developer did to make the platform become 'brick', and @NABICHAN maybe you can try to use the tool to erase the image in the flash to try to restore the MCU.

BR,

Jeremy
