11 years ago --- Quote Start --- Solved ..... --- Quote End --- Not so fast ... :) --- Quote Start --- I took a Cyclone card to my office, connected it to USB on my Laptop and ran nios2-terminal from the NIOS Command Shell and got a connection. Next, I powered down the Cyclone card and then powered back on using the brick power and the card power slide switch. The resulting behavior is a red MAX_ERROR LED. I will tell the automation team not to do it or to somehow release the connection before cycling the Cyclone PCIe slot power. . --- Quote End --- Just to avoid confusion on my part, can you run through this sequence without using nios2-terminal? I just plugged in my card, and no combination of power cycling, unplugging the USB connector, or power cable with or without toggling the power switch off causes a red LED to come on. If you can establish that its the nios2-terminal connection that causes the issue, then you can probably disconnect, power-cycle, and then reconnect. Cheers, Dave
