IMPORTANT

To update the firmware and keep the runtime configuration unchanged please use the following command:

flashrom -p internal -w apuX_v4.15.0.2.rom --fmap -i COREBOOT

The persistent runtime configuration works only when migrating from versions v4.14.0.1 and later. The feature is not yet supported on apu1. Flashrom version needs to be v1.1 or newer.
