When the Antminer T17+ kernel log shows Chain [0] find 0 asic, how should we troubleshoot the miner's fault? This article will give you a few ways to troubleshoot this.
Troubleshooting:
1. First, swap the data cable of the Antminer T17+ hash board that displays "find 0 asic" with the other two normal hash board data cables (only one side of the hash board is exchanged) to exclude the data cable and Antminer T17+ control board problem.
2. Use fluke 15B+ multimeter to check whether the total voltage range is normal, such as abnormal. It is necessary to check whether the PIC, MOS tube, and boost circuit voltage are abnormal.
3. Check whether the RI signal is normal and directly find the RI signal of a group of chips on the edge of the domain from the intermediate domain for detection. If it is normal, we will check it forward; if it is abnormal, we will check it backward (the transmission direction of the RI signal is from the last chip to the first chip).
4. The general log and fixture detection display "ASIC=0 or NO hash board", which mainly checks whether the voltage of the chip's RI signal and the ground value is abnormal. If there is any abnormality, most of them are caused by chip pseudo soldering. Solder it twice first. If it cannot be solved, replace the faulty BM1397 chip.
