Title: [DragonMint T1] All 3 boards died after power failure Post by: tim-bc on October 13, 2018, 12:56:29 PM Hi everyone,
I have one DragonMint T1 in a facility that lost power a couple days ago due to a passing storm. Now, when the T1 boots, it will not mine. Code: Oct 13 12:49:22 dragonMint cgminer[1480]: Started cgminer 4.10.0 The "ERROR - failed to recv spi data" is present for all 3 boards. I tried both soft reboot and hard reboot, no change. Any ideas? Update: Got 1 board back after another reboot, but then it dropped back out due to too many resets. So we are back to square one. Here is a copy of the most recent log - https://pastebin.com/M7j8ywNT Title: Re: [DragonMint T1] All 3 boards died after power failure Post by: HagssFIN on October 13, 2018, 01:08:40 PM Have you tried different firmware versions?

When I tried flashing back to May 5th it froze around 30%. Log - https://pastebin.com/wbq4qsWC. I had this issue before when upgrading, I'll move it to a different network and try flashing some different firmwares.

Sounds good. I'll try that when I can (in a couple days) and let you know what happens. I guess there is always the Braiins OS as well.Title: Re: [DragonMint T1] All 3 boards died after power failure Post by: sarcheer on October 14, 2018, 11:11:55 PM Sounds good.

I’d hold off on the Braiins OS for now, its still in alpha and if the install goes wrong (no one has been able to get it working on the T1 yet) there’s no way to undo it since there’s no SD card slot. They actually recommended no one attempt it with the T1 after it was brought up that there is no SD slot.

Title: Re: [DragonMint T1] All 3 boards died after power failure Post by: tim-bc on October 16, 2018, 07:59:30 PM do you have the older firmwares? Yes, I have five Halong T1 firmwares in total. It is running the latest one right now, so tomorrow I think I'll try downgrading to the second latest and see what happens. So, I had unplugged it three days ago. When I came back and plugged it in today, all of a sudden all three boards work again. I don't know what to make of it. It's weird how the T1 hashboards seem to randomly decide whether to work or not. I had originally left it unplugged for a few hours and nothing happened when I plugged it back in. I guess three days is the optimal time period for a resurrection? :P |
