One can't use HALCoGen to set the SPI baudrate. It always comes out to be VCLK1/40. So in the case of both the RTIHU and the Launchpad, this ends up being 2Mhz. It is reasonably easy to add code outside of that generated by HALCoGen, and I think there are fixes that we can make to HALCoGen in an XML file somewhere, although I have not tried it.

Note that this bug was reported to TI 10 years ago and the response was that the bug would be fixed with a patch soon. Nope. I currently have the latest and greatest version (4.07.01) and it still has the problem.

Note also that the way the driver on both PacSat and Golf-TEE works, it only makes a little difference for relatively small transfers.
