11 years agoDave and others,
I have attached some NIOS Command Window results in the hang state and not hang state. Here is the output. Issuing nios2 flash command: "C:\altera\13.1\nios2eds\Nios II Command Shell.bat" nios2-download -r -g > %TEMP%\nios2-download.txt there are no nios ii cpus with debug modules available which match the valuesspecified. please check that your pld is correctly configured, downloading a
new sof file if necessary. This kind of tells me that the FPGA did not load successfully after a power cycle of the system. I tried pressing the PGM_CONF in the error state and the error LED goes off then on again. I have a log of automation results and apparently a card that is hung with the Error LED on had just previously passed, indicating the main thing was probably a power cycle ... Now I am wondering if somehow the USB "connection was possibly active from the PC to the USB controller on the Cyclone card , when the Cyclone card was re-cycled via the PCIe slot power being cycled off then on ... In this case, the USB controller didn't get a power cycle since it is held up via the USB +5VDC from the host PC . I will try that experiment to see if I get the same behavior . Thanks, Bob.
