Hallo Bjorn & Kenji,
the hot-plug was enabled, but today I have received a new BIOS from Congatec which solves the problem.
Among the fix is:
_BBRAR009 to BBRAR110:_
2. Enabled PCIExpress / ExpressCard basic hotplug support. Enabled event handling support.
Now after the manual rescan my FPGA board gets detect correctly and I can access its registers in the correct way.
Many thanks for all your supports.
My best regards, Ghani
