Hello Jeff,

just tried to build the xylinx_zynq_zedboard BSP without any problems.
What is really odd from your log is the

How did you build your tool chain?

For my test, I used one from a slightly outdated (about a month) RSB
revision 295c197b51 because I had that one already built. libbsd and
RTEMS are about one month old too. Which revision Do you use? On what
host system do you work?

Kind regards

Christian
