LP-MSPM0G3507: Setting CLKOUT

Part Number: LP-MSPM0G3507
Other Parts Discussed in Thread: SYSCONFIG

I am just getting started with the MSPM0 and Theia stuff, so I will try to keep the stupid questions down to a minimum. But I am in the process of figuring out the sysconfig stuff, especially as it relates to clocks.

I am trying to figure out how to turn on the 48 MHz crystal on the launchpad. (I wish there were sysconfig examples like the old code-based configuration examples in CCS)

As part of that, I am trying to activate the CLKOUT on PA10. I have it configured this way:

But no joy. Do I have to turn on a peripheral GPIO somewhere?

    Never mind. I just realized that the PA10 pin is shared with the UART, so I had to set the jumper to send it to the boosterpack header rather than the XDS110. (I don't know how the XDS110 liked a 3.2 MHz square wave).
