S17+ Kernel – Antminer S17+ Read temp sensor failed

According to the backstage kernel log, Antminer S17+ read the temp sensor failed, which means the temperature sensor chip is faulty. In this case, the hashboard will not start, or the miner will stop running.

Troubleshooting:

This will require hashboard level repairs. The first test is whether the voltage and resistance of No.51 and No.54 ASIC chips and their corresponding temperature sensor chips are abnormal. If they are abnormal, they need to re-solder or replace the faulty BM1397 chip. On the other hand, if the voltage and resistance values are normal, check whether the domain voltage and the 1.8V and 0.8V power supply of the same domain are normal.

Test method: Use the DC gear and diode gear of the fluke17B+ multimeter, connect the red test lead to the corresponding heat sink, and test with the black test lead.
