Hi all, thanks for your quick answer. I wanted to test the u-boot option with coreboot payload on x86 first. So I built coreboot and did a target download with 2 dead devices at the end. I am just about to restore these devices (customized ones) with some difficulties in doing this ;-)...
When I have restored the devices I will continue my u-boot attempts. I will still have another x86 board soon with Apollo Lake E3950. The board vendor told me that there is really no way to use u-boot as BIOS replacement. Has anyone experience with u-boot and Apollo Lake? @ Bin and Simon: do you have any idea if u-boot has multiboot2 support? https://www.gnu.org/software/grub/manual/multiboot2/multiboot.html Best regards Mathias -----Ursprüngliche Nachricht----- Von: Stefan Roese [mailto:s...@denx.de] Gesendet: Freitag, 16.

Yes, using U-Boot as bootloader (without BIOS or coreboot) is definitely possible for BayTrail boards. And the boot time is definitely much better compared to usual BIOS times. I suggest you take a look at some of the available board ports and the documentation: doc/README.x86 Minnowboard MAX should be a very good example. > +CC Stefan Roese, IIRC he did something with U-Boot on X86.
