No console output on Custom Zynq Board

[Andy James]

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
