I'm using CCS5.3.00090 installed on Windows 7 x64 sp1 with a MSP-FET430UIF JTAG and yesterday, when I came back from lunch, it stopped being able to load software to my MSP430F5510 dev board. It was working fine before, and when I came back, I've been getting the error "MSP430: Error connecting to the target: Unknown device"
I've gotten this error every time I've tried to connect the JTAG since, and I have another JTAG, I tried that and I'm still getting the same error. the same is true with a different dev board. Am I missing something? Is there a way to troubleshoot this?
