Posted on May 17, 2011 at 14:30Turns out the board documentation was wrong and that USART4 is the correct one.  After making that change, serial now works.  This issue can be closed.

Posted on May 17, 2011 at 14:30I can't post my driver because it is company IP but the USART is identical to the one on the STM32F1xx, but the GPIO setup is completely different.  So I'm looking for the GPIO settings.
