In your logs under ECMM the value is [1] which is abnormal according to the description logs from Canaan this error is pointing to your MM board there might be a connection problem between the hashboard and the control board. And look it only detects 1 hashboard.
Would you mind to try to replug all cables from the control board and hashboard then test it again.
I disconnected it, cleaned it but the same problem.
thanks.
