Dear All,

I am new to mining and have bought some Avalon miner A851. All plug-in accordingly but cannot be mining and urgent help needed. Really appreciate it and thanks.

I'm not so familiar with the logs of the old Avalon miner but I would like to ask if this is the whole API logs?

If not, post the whole API logs and use insert code tag(# icon) before you post or if you experience a character limit then you can paste it to pastebin.com and share the URL here.

The only thing that I could suggest is to try it to upgrade to newer firmware because your Avalon firmware version is 2018
You can download the firmware directly from here https://download.canaan-creative.com/

Also, check this "troubleshooting and repair guide by HagssFIN"

Dear BitMaxz,

Thanks for your kind advice. After some troubleshooting able to solve the problem. The Raspberry Pi 1B plus cannot be used, we change to Raspberry Pi 3B problem solve. But now another issue with A911, we used the same method for A851 setup, but cannot???
