One of my Apollo's has a problem and I want to figure out how to fix it or at least diagnose what is wrong.

I think the fault is in the OrangePi, because the Apollo still mines as it should when I connect it as a Standard unit.

It had been hashing and node-ing away happily until it suddenly stopped to send hashes to the pool, so I had a look.

Turning off the power and turning it back on did not lead to the usual unsupervised resumption of hashing and sharing operations.

Then, it started working again for no apparent reason and I did not post this, that was a few weeks ago.

But now it's playing up again, the connection to the pool is strangely intermittent, see image. Its a full node and a standard node.




The other issue is that the HDMI does not reliably connect to a monitor, and the resolution is all wrong and very grainy.
