I'm attempting to run the RTEMS "hello" sample application  on a custom Zynq 
board with 7030 device. I built and ran the  sample application on a Zybo Z7-10 
without any issues.
My custom board uses UART0  and a 100MHz UART clock with 666MHz CPU clk , and I 
have changed the  BSP to suit these values. I have verified that the Zynq UART0 
registers are correctly
set  and can get some console output via directly writing to the UART0  TxFIFO 
address at 0xE0000030, however printf does not give any output. Does anyone 
have any suggestions as to what I may have missed?
Thanks
Andrew James
