S17 Kernel – Antminer S17 Pro wrong temp sensor type

The temperature sensor chip is mainly used to sense the temperature of the hash board and its surroundings. If it is damaged, it will cause abnormal temperature readings, and the hash board will not start when the temperature is too low (the kernel log shows that the temperature sensor reading failed), or the miner stops running when the temperature is too high. So when the temperature sensor chip fails, you can refer to the following methods for troubleshooting.

Check method:

1. Most temperature sensor chip failures are caused by chip soldering. It is necessary to troubleshoot by measuring the chip voltage and ground value and find a hash board of the same model or another good hash board for data comparison.

2. If the temperature sensor chip is normal, it means that the chip through which the temperature sensor circuit will pass may be abnormal.

Test method: Use fluke 15B+ multimeter DC gear and diode gear, red test lead to connect to the corresponding heat sink, black test lead to test. Compare the measured chip data with the standard chip data. If any abnormality is found, it is recommended to replace the faulty BM1397 chip directly.
