Hi All,

I'm working with a recent rtems head (23 April 2014) and the 
'xilinx_zynq_zedboard' BSP.

I have everything up and running but somehow it looks if my clock / sleep 
relation is wrong. If i perform an usleep(1000) it will sleep for 2000 us 
instead of 1000. Also the baudrate of the serial port is 57600 instead 115000. 

I wonder if it has something to do with the GTC (Global Clock Time)  which is 
always clocked at 1/2 of the CPU frequency for an ARM Cortex A9.


Has anybody experienced similar problems or does somebody  perhaps have an idea 
why such an error might occur?

Best regards,

Giovanni
