Booting this UEFI on the Raspberry Pi 3 B+ #41

Closed stefan2225 closed 5 years ago

stefan2225 commented 5 years ago

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?

andreiw commented 5 years ago

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

Thanks for the Fedora report.

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 commented 5 years ago

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)

Here they are: (pretty much latest VC firmware files right now)

bootcode.bin: 410DE1021E20F1051A5518BC9E863AE9 fixup.dat: 7F160E8B2A7B7D664D9F7930F1D3350B fixup_cd.dat: DC619911230B4D131E67CA36C6A74415 fixup_db.dat: A9FEDCE9810A06935A3CEA0ABECA165A fixup_x.dat: DCF3058140F6C877E2B4CE2C067CA34D start.elf: F17A9D31ADD2B653FACE3DBD25A96D58 start_cd.elf: 2E281DD504E9C34C05539437E3DEBAB7 start_db.elf: 18EC0E15014EA9A9D631FA83C434C1AA start_x.elf: DBDB64DF645DF33334416626844A8EB2

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 commented 5 years ago

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

andreiw commented 5 years ago

yes, I was talking about UEFI

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

stefan2225 commented 5 years ago

@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 commented 5 years ago

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).
