FAQ

Q: I can't get the backchannel UART to connect. What's wrong?

A: Check the following:

•

Do the baud rate in the host terminal application and the USCI settings match?

•

Are the appropriate jumpers in place, on the isolation jumper block?

•

Probe on RXD and send data from the host. If you don't see data, it might be a problem on the host

side.

•

Probe on TXD while sending data from the MSP. If you don't see data, it might be a configuration

problem with the USCI module.

Q: The device is not answering to any communication, JTAG or UART.

A: If you are experiencing difficulties in communicating to the attached MSP430 target MCU, even though

all the communication drivers for the MSP-EXP430G2ET are loaded correctly, the emulator is probably set

to a wrong communication state. This can be fixed by reconnecting the LaunchPad development kit and

restarting the communicating application. Also make sure that all the jumpers on J101 are connected

properly between the emulator and the target MCU.
