Hi,

Some general thoughts and questions:

1. Is this was tested before and approved to be working setup or new untested prototype?

Yes all the boards are working and tested prototypes. This assembly error happened on 4 boards ,out of them 2 are working and 2 are not working.

2. Have you checked that FPGA board is not damaged due to wrong FPGA and board rework? (There are no short circuits, no damaged power supply IC ect.?).

Yes , we have checked for any short circuit and also power supplies on-board are working fine.

3. Does FPGA boots to user mode, can it be reprogrammed?

We could program it.

4. Have you checked that PC motherboard is not damaged by installing other working PCIe board?
