This seems to persist until the board is power-cycled, and this is triggered (inexplicably) by the firmware booting to "Eth On".

I could shut this error up by setting this to false: https://git.m-labs.hk/M-Labs/zc706/src/branch/master/libboard_zc706/src/boot.rs#L115

Ah! openocd is missing core1. Thanks for debugging that.

If core1 gets just reset but not stopped it is going to idle in WFE. Sounds okay to me.
