Booting this UEFI on the Raspberry Pi 3 B+

[stefan2225]

The UEFI is fully compatible with the RPi 3B+ and I managed to install Fedora 28 Minimal with a custom DTB on an external USB Stick. I just needed to download the latest bootcode.bin, start.elf, fixup.dat. Additionally I needed to add the files fixup_cd.dat, fixup_db.dat, fixup_x.dat and start_cd.elf, start_db.elf, start_x.elf to get the RPi booting. Why are the _cd, _db and _x files needed?

The current prebuilts already have the 3B+ compatible bootcode/start/fixup. Did that not work for you? Thanks for the Fedora report. A

I just get the green LED blinking 4-5 on the RPi if I just use the already provided bootcode/start/fixup without the cd/db/x files. I also got no HDMI output, not even an rainbow screen. BTW I'm using the latest release build.

[andreiw]

interesting, ok I’ll refresh those bits... Can you provide the md5 sums for the known good VC firmware files (boot code, fixup and the rest) A

Is it normal that Fedora detects when I remove the SD Card and when i reinsert it? I thought I have seen in a issue that that doesn't work.

[thchi12]

Maybe that issue is talking about detecting card removal in UEFI?

[andreiw]

yes, I was talking about UEFI A

@stefan2225 Which dtb did you use for the rpi 3b+?

[stefan2225]

@satmandu I extracted the DTB from a Fedora 28 image with U-Boot.

There is a config.txt option that switches between the normal, cd, db or x versions. If you set that to the x version, it won't even look for the normal one.

[andreiw]

Yeah don't do that.

I found by my Pi3B+. I don't confirm the boot issue. If you copy a build directory verbatim it works just fine. You shouldn't need the cd, db or x versions of anything (because the config file doesn't refer to them).
