MSP430F5638: Boundary Scan BSDL file

Thanks for the response, I have some follow up questions.

Is there any advantage to using boundary scan for the other parts on the PCB: GPS module, WiFi module, accelerometer / gyroscope, magnetometer, switches, op-amps, onboard headers, LCD? Would this require a separate JTAG boundary scan header?

Do the MCU's not support boundary scan because they have a huge range of internal peripherals which have to be setup, tested, & used via internal hardware & software?

Based on MSP430 Programming with the JTAG Interface (SLAU320), you should be able to use the MSP430 in BYPASS mode. That will output data received on TDI to TDO with a 1 cycle delay.

I can't speculate on exactly why the MSP430 and MSP432 were not designed to support boundary scan, but it's true that many of the more advanced peripherals would probably be painful to use/test in this configuration.
