Description

The RW EC image built within the Coreboot build system for nyan_big does not work correctly on the current git master. This is when building a full ChromeOS flash image.

The problem seems to be watchdog-related, as shown in the log:

This breaks the whole boot process as vboot waits for the EC to reply. Eventually, it triggers a reboot after timeout, going endlessly in a reboot cycle.

Disabling EC software sync in the GBB flags works around the issue, but a proper fix would be to fix the EC code.

It looks like CrOS EC TOT runs fine on big now, so we can close this.
