Fellow Developers,
We are using a MSP-FET430UIF (debugger) to communicate to a custom board that has a MSP430G2553. We are successful communicating to the device utilizing 2-wire spy-bi-wire and the debugger supplies voltage (i.e. power) to the MSP430G2553. However, we need to use the custom board when it is self-powered (it provided 3.3V regulated to the MSP430G2553). The debugger does not wants to work in such mode. We have verified the pin connections required for operation in such mode and we believe are correct.
In one isolated attempt we changed the voltage level in the debugger settings to 3.3V, and it was able to communicate to the MSP430G2553. We were not able to repeat this, so it is back at not working. I am inserting screen shots of the errors produced by the debugger.
I hope someone can help!
