What is XDS110 Class Auxiliary Data Port?

Other Parts Discussed in Thread: LAUNCHXL2-TMS57012

This appeared when I installed / connected a LAUNCHXL2-TMS57012 board.

I assume it's a USB CDC device enumerated by the on-board TM4C but what is its purpose?

    Hi Kirk,

    The Auxilary port's function will be board specific.   In some cases it will be available as a 2nd UART channel back to the host;  but that's not the plan for LAUNCHXL2-TMS57012.    At the moment that device is reserved - just ignore it.    Sometime in the future we may add the capability to stream dynamic current measurement back to the host over this port,  but the project to make that happen has yet to be commissioned.

    In any case you can just ignore the port for now.  It's a CDC class, but there's nothing useful you can do with it given the current XDS110 firmware.
