SETUP: CCS Code Composer Studio + XDX200 USB/JTAG, 2x TMS470MF06607 (PZ) mounted on a single board with 2 separate circuits with individual JTAG connectors.
Hello, we experienced a programming issue with one of the microcontroller recently, CCS prompted "unable to access device register", even though it has been compiling and loading the code prior to this without any problems. We disconnected the JTAG and connected to the other TMS470 / circuit, showing the software / hardware setup was correct and working.
It seems that the microcontroller is now bricked and not running any code. We checked for best practice / guidance on the TI website and all appears to be ok with our setup / methodology.
Is there a way to request TI to inspect / assess this now faulty microcontroller for any root cause / failure analysis?
