Antminer S19j Pro nonce crc error - S19j Pro Kernel Log

The following fault comes from an S19j Pro miner user who reported to us that he found nonce crc errors in the kernel log after the miner kernel log showed that the initialization was completed. This also caused the hash board not to start running, and the following continuous screen refreshes appeared. We do not provide the following refresh interface:

Solution:

First, remove the two hash board cables, only run one hash board, and repeat this method. In this way, you can find which hash boards are not running. Then, use the fixture to test the corresponding hash board and check the test log. The abnormal RI signal voltage of the ASIC chip generally causes this kind of failure. If you find the chip with abnormal RI signal voltage, you can solve it by directly replacing it.
