The Configuration Problem Solver

Data loaded backwards.

    Check to see if the data is backwards by capturing the first two bytes of the Header on the DOUT pin. If the configuration data is being byte-swapped in the wrong direction then <0000 0100> instead of <0010 0000> would be observed on DOUT. This may also be verified at the D<7:0> data input pins on the FPGA. The D0 is actually the MSB; therefore, in the example byte <0010 0000> the '1' should be on the D2 pin.
