Hi there,
I am trying to blow the JTAG security fuse on an MSP430G2553 using an MSP-FET as the hardware and Elpotronics FET-Pro430 as the software. I understand that the 2xx series requires the TEST/VPP line to be connected as per the image below for SBW. However, once I connect that line I cannot seem to establish JTAG communication with the FET-Pro software or even Code Composer Studio. Disconnecting TEST/VPP allows me to flash the chip without issues. Could this be an MSP-FET hardware malfunction?
Thanks,
Kyle
