5 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's 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 MSP430. 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: So the onboard emulator is really open source? And I can build my own onboard emulator?

A: Yes! We encourage you to do so. The design files are on ti.com.

Q: The MSP430 G2 LaunchPad had a socket, allowing me change the target device. Why doesn't

this LaunchPad use one?

A: This LaunchPad provides more functionality, and this means using a device with more pins. Sockets for

devices with this many pins are too expensive for the LaunchPad's target price.

Q: With the female headers on the bottom, the board doesn't sit flat on the table, and I can't

unsolder them. Why did TI do this?

A: For several reasons. A major feedback item on previous LaunchPads was the desire for female

headers instead of male ones. But simply using female instead is problematic, because compatibility with

existing BoosterPacks would be lost, and some people prefer male headers. So, adding female headers

without removing male ones satisfies both preferences. It also allows more flexibility in stacking

BoosterPacks and other LaunchPads.
