Yesterday I received my 4th LV08 and set it up with my details and mined for several hours at 3TH without any problems. Usually I run my miners with the original loaded firmware for a day or so before I open them up, backup the firmware and install my own modded firmware. However, I decided after only a couple of hours to install my modded firmware on this my 4th LV08.
No matter what I've tried, only 6 out of the 9 ASIC chips are mining. I used the same modded esp-miner.bin and
www.bin files on this miner as with my other three LV08s but still this 4th LV08 has only 6/9 ASICs working. I have confirmed that all 3 TPS546 regulators are added to the i2c bus and that they have been initialized with the same settings. However, it's the middle voltage regulator that is not supplying power to the middle 3 ASIC chips.
I've even used a full firmware backup (v2.5.1 TCH) from one of my other LV08 miners on this new 4th LV08 but the results are the same, only 6/9 ASICs are mining. When I reinstall the original firmware that I backed up before I installed the updated firmware (luckily), all 9 ASIC chips are mining again!
All four LV08 miners appear identical. Looking at all the serial numbers, my first two LV08s are lower than my 4th LV08. But my 3rd LV08 serial number is higher than my 4th one!
Anyone else experience this issue?
I have experienced the same.
And it is mostly 1 of the VR's that stops working but not always the same. eg VR1 stops, VR2&3 keep working. [powercycle] all 3 working, and after a while VR 1&2 working, VR3 no longer produces output power.
I wish someone would include syslog client into bitaxeos so all logfile could be collected on a syslog server in a LAN so we could see the log files that triggered the event.
