Well, never mind, I rebooted the target and the host systems, did a "repo sync" of my chromeos setup, did a full firmware rebuild (described in the care and feeding doc) then did a flash of the coreboot firmware, followed by a flash of the ec firmware and the target system automatically booted successfully after the ec firmware flash.
Perhaps it could have been an issue with unsynchronized ec and coreboot firmware?
Possibly. I am guessing that the EC was unable to jump to the other copy for some reason (this isn't in the output you posted, just a guess), and the EC locks down its active copy which would explain why attempting to flash it failed. You should also check the EC serial console whenever you see EC firmware upgrade failures.
