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 eUSCI 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 eUSCI module.
•
Consider the use of the hardware flow control lines (especially for higher baud rates).
Q: The MSP G2 LaunchPad had a socket, allowing me change the target device. Why doesn't this
LaunchPad kit use one?
A: This LaunchPad development kit provides more functionality, and this means using a device with more
pins. Sockets for devices with this many pins are too expensive for the target price of the LaunchPad
development kits.
