Honored ContributorHi Bob,
--- Quote Start --- I have attached some NIOS Command Window results in the hang state and not hang state. --- Quote End --- The NIOS tools require communication with a *configured* FPGA. Your comments above already established that configuration failed, so its no surprise that a NIOS tool will not work. This is why I requested you run jtagconfig -n, as this would establish whether the JTAG chain was still viable in the error state. If it is, then you might be able to automate the recovery. --- Quote Start --- I tried pressing the PGM_CONF in the error state and the error LED goes off then on again. --- Quote End --- Hmm, that is weird. If the red LED comes back on *again* that would imply the MAX II does not like some hardware pre-condition for loading the FPGA. Did you look at the MAX II code? Can you please run jtagconfig -n when the red LED is on, and see whether the JTAG chain is still detected ok, thanks! Cheers, Dave
