Cyclone III Programs, Doesn't Boot

Hi,

The reason why we ask to test the good FPGA on the problem board is to check whether the board is the problem or the FPGA is the problem. If the good FPGA works on the problem board, it means the board is fine but the current FPGA is the problem, if the good FPGA is not working on the problem board, it means the board is the problem.

Since you mention that these boards did not work previously and they were assembled and failed to boot during test. You have also try inspected the boards for irregularities, reflowed the BGA package FPGA, and replaced the FPGA but nothing works. Hence testing the good FPGA on the problem board can be our last effort.

Regards,
