I now have two serial channels (diag and printf) working on the same HW
port but when i want to change the diag to use SMC2 instead of SMC1 then
i hang in the quicc_smc1.c putc function because a BD flag indicates
busy:

while (bd->ctrl & QUICC_BD_CTL_Ready)

The only change i have done in ConfigTool is to change the "Diagnostic
Serial Port" from 0 to 1. Is there any other location that i need to
change to make this work?

Regards, Daniel
