When the Antminer L3 kernel log shows a crc check error, you can use the following methods to troubleshoot.
Troubleshooting:
1. Check the mining pool settings; for details, please refer to Antminer L3 Manual.
2. Check whether the domain voltage is normal. If it is normal, check whether the voltage of the RI signal is normal. If the voltage of the RI signal is abnormal, check the domain voltage of the domain where the chip is located and the LDO chip's 1.8V input and 0.8V output. If the voltage of the LDO chip is abnormal, replace the LDO chip. If the voltage of the LDO chip is normal, there may be a problem with the ASIC chip in this domain. Therefore, it is necessary to check whether the signal voltage of the chip is abnormal. If it is abnormal, re-solder it first. If the problem cannot be solved, replace the ASIC chip.
