I made bitaxeUltra 204 on PCWAY. The chip used is BM1366AL. I used esptool to flash esp-miner-factory-204-v2.0.7.bin, but it didn't work and it showed that it could only accept new jobs. How should I measure whether there is a component failure or misalignment? Or maybe my programming method is wrong. The heat dissipation is also normal and there is no high temperature protection.

The power supply used is also normal and it works on another bitaxe I purchased online. But on the finished product produced by PCway, it is observed that the input power is only more than 300 mA, and it should be 3000mA.

Fortunately, two of the five devices are working normally, but I don't know how to use the TP point to determine which part of the three faulty devices is faulty.

Everything looks good but it's not mining sounds like an ASIC issue to me. Likely the ASIC isn't soldered properly, or the chip is bad.

I'm going to close this as it isnt a bitaxe issue. Can you bring this up on the OSMU Discord? There is an invite link at bitaxe.org

Some other people have attempted PCBWay assembly with similar results.

一切看起來都不錯，但對我來說，這不是挖礦，聽起來像是 ASIC 問題。可能是 ASIC 焊接不正確，或是晶片損壞。

Thanks for your reply, you are right. After reinstalling BM1366 on the 3 previously faulty devices, there is still no hash value. Later, after I swapped the chips of a normal and abnormal device, the results were also swapped. Sure enough, it was a fault with BM1366.
