Looking at it - green light on Ethernet port is OFF, only orange n ON. If I do cold restart (power OFF-power ON) it enables both onboard green LEDs, ethernet port enables both LEDs(green/orange) for short time just after power ON then green light turns OFF, orange flashes time to time but green doesn't go back ON. Router also doesn't show IP allocation to MAC corresponding to Parrallella board. Currently it headless, usually I logged on remotely to it (putty/SSH) so it just black box. I could remove microSD card from it and attempt to read it on other device. But where to look? It's Linux box so judgements from Linux profies are welcome. PS. Fastest move could be just re-flash it but it contains build environment already I hardly recreate fast. So would be very desirable to repair current installation (hope it's software issue, not hardware one). SETI apps news We're not gonna fight them. We're gonna transcend them. ID: 1948570 ·

My first question would be, How do you know it is booted up if is only accessed headless? Does it perform some function that you know it is running? You might want to get a monitor on it and look. To check the file system, try Google "parallella ip config file" it shows Linux info. Or similar searches like "Linux ip config file" ID: 1948579 ·

I don't know how hard this will be under Linux, but if you can uninstall the driver for the LAN, reboot and then reinstall the driver. Or even see if there is an upgrade for the LAN driver?

My first question would be, How do you know it is booted up if is only accessed headless? It lights ON secondary onboard LED. If boot process doesn't start that LED remains dark.

I currently have two (Boinc 6 and 9) configured that way. I don't know about the linux drivers for such, but if you can plug in an adapter and establish a connection, you get to keep crunching......
