The Configuration Problem Solver

CONCLUSION

The STARTUP Sequence has not completed.

    To complete the STARTUP Sequence all that is needed are a few more clock cycles. When configuring in the Peripheral Mode the Bitstream and PROM files should always be generated with the Aligned_Lengthcount Option. Aligning the bitstream to DONE can cause an incomplete STARTUP. If Align_DONE was selected then strobe another byte of Logic `1's into the FPGA to generate 8 more CCLKs. See also the related answers.
