This means one of three things, you have an amlogic "cousin wangs covid ARM sale" control board(thumb microUSB drive replaced microSD), a beagle bone control board(SD card slot is inside the control board housing), or it is one of the new "cousin wang's 2023 ARM CPU sale" control board I've started hearing rumors about(idek).

The logs look fine also.

You can try these options.
1. Restore defaults in web interface and reload pool info.
2. Try configuring it with a remote tool like BTCtools.
3. Load/reload the latest firmware update from bitmain's website.

Number one worked for me last week when I had a similar seemingly fine log that simply didn't want to hadh but that machine was new to me, yours was running fine.
