<br>
the epics-base version in github does not work with RTEMS5 It needs my extensions for this.<br>
Therefore I suggested that you first build epics7 for e.g. RTEMS 4.10.<br>
Then the easiest way is to build epics7 for RTEMS-pc386-qemu. This is fully supported.<br>
So you learn how to build EPics and then you can develop a first rsb-set for it.<br>
If this works, we will work on RTEMS5 and xilinx-Zynq.<br>
