Attempting to get IMX_UART_LOG_TRACE messages

Hi,
I am trying to get trace messages from the imxuart driver running on my iMX board to display in any way.  My first attempt was to use the tracelog command in windbg as I seem to remember that was the correct method.  Unfortunately, that command is not recognized and I can't seem to figure out how to get it to work.  I also tried using the GlobalLogger by using Tracelog from Powershell once the board has booted, but that also seems to not be working.

Please let me know what additional information I should supply.

Thanks for any help in advance.
