Hello, there appears to be failure with the mt7621 buildbot process which started from the 23rd November 2017 build process onwards. I've found some errors in the logs below which I have shortlisted. I'm not a developer but could this problem be related to the firmware binary?
os-image partition too big (more than 1703936 bytes)
Failed to open firmware file
