Antminer S19j Pro Chian 2 only find 0 asic - S19j Pro Kernel Log

How to troubleshoot when Antminer S19J Pro kernel log shows only to find 0 asic? The following points are for your reference only.

Troubleshooting:

1. Swap the data cable of the Antminer S19J Pro hash board showing "find 0 asic" with the data cables of the other two hash boards (only the side of the hash board is exchanged). First, exclude the data cables and the Antminer S19J Pro control board question.

2. Check whether the total voltage domain is normal, such as abnormal. It is necessary to use a fluke 15B+ multimeter to check whether the PIC, MOS tube, and boost circuit are abnormal.

3. To measure whether the RI signal is normal, it is generally not necessary to check next to each other. For example, first, find the Ri signal of a group of chips on the edge of the domain for detection. Then, if it is normal, we will check forward; if it is abnormal, check backward (The transmission direction of the RI signal is from the last chip to the first chip).

4. The general log and fixture detection show "find 0 asic", which mainly checks whether the voltage of the chip's RI signal and the ground value are abnormal. If there is any abnormality, most of them are caused by chip pseudo soldering. First, soldering twice. If it cannot be solved, replace the chip.
