The Configuration Problem Solver
CONCLUSION
Configuration Data is Incorrect.
It is highly unlikely that the loading of incorrect configuration data would not result in a DataFrame ERROR (INIT goes low); however, if the Preamble sequence <0010> is never observed by the FPGA then the configuration process would never have started. Thus, no error would be detected. Check to see if the data is backwards. If <0000 0100> instead of <0010 0000> was detected on DOUT then the configuration data was inappropriately byte-swapped for memory storage. If the data is simply incorrect then this is most likely a result of a problem in the application board or timing specification requirements not properly met. See also related answers. |
