How to use hash board code editor for EEPROM chip programming errors

For those who have encountered EEPROM chip programming errors on their S17+ hash board, the hash board code editor can be used to re-flash the EEPROM file and restore it back to normal. This article will provide an overview of the steps required for using this tool to troubleshoot such errors.

Troubleshooting Pattern NG error in the log

When a Pattern NG error appears in the testing fixture’s log, several methods exist to troubleshoot it. Firstly, the hash board code editor should be used to re-flash the hash board’s EEPROM file. This can often have a positive effect as the EEPROM chip stores operation information for the ASIC chips – so if anything is abnormal, it may affect the chip’s hash rate. If this does not fix the problem, then further investigation is needed. Chips with an abnormal hash rate can be identified by looking at the test fixture’s log, and they should be replaced directly. However, if any of the chips have recovered their hash rate after re-flashing their EEPROM file, then they do not need to be replaced.

Replacing chips with low or 0 hash rate

Replacing chips with low or 0 hash rates is a common issue when dealing with ASIC mining hardware. The first step to resolving this problem is to re-flash the EEPROM file, as it stores all of the operation information for the ASIC chip and can affect its hash rate if it becomes corrupted. If this doesn’t work, then you may need to replace the chip itself. You should use a hashboard tester to perform chip detection and determine which one needs replacing based on the test results. After locating the faulty chip, you will need to re-solder it to function correctly again before performing fixture tests multiple times until your board passes them successfully. Finally, create maintenance records for feedback before installing your entire miner back together again.

Re-flashing the EEPROM file before replacing chips

Re-flashing the EEPROM file before replacing chips is a beneficial troubleshooting method for Antminer S17+ hash boards. When an error in the EEPROM chip program of the hash board occurs, re-flashing it can help to restore normal operations and determine if any further repairs are needed. After re-flashing, performing a fixture test will help identify abnormal hash rates and pinpoint which chips need to be replaced. This process ensures that only necessary repairs are done, helping to minimize time and costs while also ensuring optimal performance of the miner.

Performing fixture tests after re-flashing and chip replacement

Performing fixture tests after re-flashing and chip replacement are essential steps in repairing a hash board for an Antminer S17+. After re-flashing the EEPROM file, it is essential to do a fixture test to ensure that the chips on the hash board are working correctly. If any chips have abnormal hash rates, they should be replaced accordingly. Once all repairs have been completed, maintenance records should be prepared and provided to production, after-sales, research and development departments. Finally, it is necessary to install the entire miner for conventional aging before finalizing the repair process.

Tips on Troubleshooting ASICs to Avoid Future Issues

Troubleshooting ASICs can be a daunting task for novice miners. While it is essential to identify any problems with your mining hardware, it is equally important to take preventative measures to avoid future issues. Here are some tips on troubleshooting ASICs to keep your miner running smoothly and efficiently.

First, ensure that the power source is adequate for the type of ASIC you are using and that all connections are secure and properly connected. Second, check all components, including fans, heat sinks, PCBs, etc., and their respective temperatures to ensure proper airflow within the unit. Additionally, inspect the firmware of your device regularly to make sure there are no bugs or outdated versions disrupting performance levels. Finally, use diagnostic tools such as hash rate monitors or stress tests to detect any potential issues before they become major problems down the road. By following these simple steps when troubleshooting ASICs, you will increase efficiency while reducing downtime due to hardware malfunctions or other technical difficulties.


Mining and troubleshooting ASICs can be a complicated process.
