Antminer L3+ can’t find asic boards

[Rogga31]

Hi

I need some expert help on this. My Antminer just shows 0 on all 4 asic boards. Is it the status board that is faulty or is there some other issues? From Kernel log:

May 7 17:50:46 (none) local0.notice cgminer[381]: Start A New Asic Response.Chain Id:[1] May 7 17:50:46 (none) local0.notice cgminer[381]: tty_init 2 May 7 17:50:46 (none) local0.notice cgminer[381]: Start A New Asic Response.Chain Id:[2] May 7 17:50:46 (none) local0.notice cgminer[381]: tty_init 3 May 7 17:50:46 (none) local0.notice cgminer[381]: Start A New Asic Response.Chain Id:[3] May 7 17:50:46 (none) local0.notice cgminer[381]: open device over May 7 17:50:46 (none) local0.notice cgminer[381]: send cmd to get chip address May 7 17:50:48 (none) local0.notice cgminer[381]: Chain 0 ASIC 0 !!!

you have installed bliss firmware so I do not know if you have a corrupted version of it.

Did it ever work?

Did it work with bitmain firmware?

Hi
It worked on original firmware and also on Bliss firmware ( I also have the same Bliss firmware on three other L3 working fine). But when I moved the machine it stopped working.

And did you move it in the same home?

or to a different home.

It may not be compatible with the new internet.

If it is on the same internet  we can do some other troubleshooting

Moved from cellar to garage. Still on same network. And I also have three other working L3 on that network.

All sober.

Okay so assuming you simply detached the l3+ from its eth cable and walked it into another room.

You then plugged it into a new power outlet and are using an eth cable in the new spot.

Assuming the 3 good units in different room are all working.

Lets try detaching 1 good unit. leave it sit just out of the way.

bring the dead unit to the spot you detached a working unit.

plug the dead unit in boot and let us know if it works.

if it does not work put it aside.

reattach the good unit and boot it should work.


If all of the above is true then you know the problem is within the dead miner.

I hope that you had a good time!

Took the faulty machine to the spot with the working machines. Unplugged one of the working one. Use that eth cable and also the power supply. Still not working. Attached the eth cable and psu to the working one and booted up that and it works fine.
So I think that we can assume that there is something that is not working as it should in the faulty machine.

The control board sometimes dies. 
I have 2 good hash boards in the  house and three bad controllers.

It is more likely the controller died and not the 4 hash boards.

Try a few resets then flashing the controller with the firmware.



Oh BTW  the party/dinner was fun

Thanks, I will give it a go and if it doesn’t work I will change status board.
