mcu 'mcu': Unable to connect
I got this error this morning when starting my Vcore 500. I'm seriously a novice, so don't know where to start troubleshooting. I did update my RATOS Configuration Repository last night and seemed to restart OK, but didn't really monkey with it. Could that be a cause and if so, how do I go back to the previous config? Thanks,

Solution
Just fyi for those that have the same issue, I ended up flashing a new SD card and reloading into the raspberry pi and going through updates again.
