Yes I tried that also... with old cards and with new one same thing... I think now that problem is somewhere in beagle or in my network...

Cables are ok because everything worked fine, screen is blank and device is not accessible... i made card again and it did not worked... i have one knc here and i will try to change the beagles to see if it is going to work. If someone have any idea please share it Thanks

I'd noticed you'd upgraded the power supply, so figured it was possibly something that came loose during the process... glad it's working

Thank you, sir.  That will save me a few steps.  I'll verify it tomorrow and return with what I find out!

Yep, it's the furthest card.. the slot numbers are written on the power board.

The numbers don't always match the chain number in the gui if a card is missing though, i.e. if one card is missing from slot 4, the gui will show chain#1-9.

Thank you, sir.  I appreciate it.

At the risk of sounding like a complete noob... if you can change things like miner configuration and ip address, why not the password, wouldn't that just require an update to the luci interface with the appropriate commands?

Tbh I think this corrupt SD problem is probably more to do with some shoddy programming than anything else. I think there is something writing to the disk the whole time and if not stopped 'gracefully', it corrupts the card. I'm finding that if I eject the card before powering down, I don't have a problem with corruption. I haven't re-imaged a card in a week
