You can use this troubleshooter to help you identify possible causes to a failed FPGA configuration attempt. While this troubleshooter does not cover every possible case, it does identify a majority of problems encountered during configuration. This troubleshooter can be supplemented with Altera's Knowledge Database to help you identify and fix your configuration problem.
What is your configuration issue?
- The device does not enter user mode although the CONF_DONE pin is released high at the end of the configuration cycle
- The nSTATUS pin is pulled low or is toggling at the end or at different point of the configuration cycle
- The nCONFIG and nSTATUS pins are released high, but the CONF_DONE pin does not go high at the end
of the configuration cycle
