Hi all,
Goal
I am using the MSP430F2272 with the TI MSP-FET430UIF Debugger. I would like to blow the JTAG fuse. My JTAG connection from FET to MSP is 4-wire SBW; VDD/TEST/RST/GND.
Problem
I cannot get either Code Composer (Target->Make Device Secure) or IAR Kickstart (Emulator->Secure - Blow JTAG Fuse) to blow the fuse. Both give me the message: "failed to make device secure".
Considerations and Thoughts
I have read through both slau320b.pdf and slaa149.pdf. It appears that maybe my MSP and/or FET debugger only supports "Fuse Programming via TDI", section 4.1 of slaa149? I hope this not to be the case as we'll have to change our board layout to add more pin breakouts!!
Question
Why can't I blow my JTAG fuse with my setup in CCS? Do I have to write my own custom JTAG code, or am I doing something wrong?
Thanks!
