Other Parts Discussed in Thread: MSP-FET
Tool/software: Code Composer Studio
I've designed and fabricated a circuit based on a MSP430F2617 reference design, but I fear I've overly abbreviated the programming circuitry. At the very bottom my KiCAD design is pictured, you can see I've directly wired TCK, TMD, TDI and TDO. I'm programming the board with the new MSP-FET and getting the 'Unknown Device' error in Code Composer Studio.
First off I think my initial mistake was there is no pull-up on pin 1 (TDO), am I right in saying this would completely prevent functionality?
Secondly I've left pin 8 unconnected, which according to this TI reference page on programming circuitry should be connected to a pin on the MSP430 called 'TEST/SBWTCK', which doesn't appear to exist on the core I'm using, therefore what should this pin be connected to instead?
Thirdly there's no resistor linking pin 7 (TCK) and pin 8 (TEST/VPP), does this also prevent functionality?
Hopefully I've covered my mistakes, but if anyone can root out more I'd be really appreciative - I'm dead in the water until I can figure out the root cause of the board's unresponsiveness.
