I used Rockchip as an example as I'm familiar with that AND *afaik* they expect the U-Boot stuff to start at the furthest offset. But when U-Boot is used, every platform uses *some* offset and then needs some space/bytes for the U-Boot binary/bits. If that goes above the 2MB mark, then the current recipes overwrite part of whole of the U-Boot binary ... making the system unbootable. So you could special case Rockchip and only use the 16MB offset for the Operating System partitions and data for Rockchip SoCs. Or you could keep the first 16MB free for all ARM SoCs and then it should work for all ARM SoCs as long as they stay below the 16MB 'mark'. Which AFAIK are all of them. > > I don't know if it's common, but AFAIK you can use U-Boot with EFI, but > > it sounds 'weird' to add it to a recipe with AMD64 in its name... > > Indeed.

And the above principle also applies when EFI is being used with U-Boot as it's specific to U-Boot. HTH, Diederik -- Sent from /e/ OS on Fairphone3
