Support Raspberry Pi Model 3B+ ARMv8?

Postby Givi » Wed Mar 28, 2018 2:58 pm

is there any plan to release an ARMv8 image compatible with Raspberry Pi Model 3B+?
I don't see any info about.
Thanks for the help!

This is shipped with 4.14.30 but I don't know what else is needed. If it works as-is, either wait for a new aarch64 image to get rolled with this or update one on a compatible device before inserting into the 3B+.

Just to confirm it does work with 4.14.31-1-ARCH.

I actually had to do arm chroot and update the installation since I didn't have the old rpi 3 anymore so if somebody needs to do the same:
Code: Select all
install binfmt-qemu-static and  binfmt-support-git from aur and start the binfmts and binfmt-service
# mount arch rpi card
mount /dev/sdx2 /mnt # system partition
mount /dev/sdx1 /mnt/boot # boot partition
cp /usr/bin/qemu-arm-static /mnt/usr/bin
arch-chroot /mnt
# update the system
pacman -Syu

After boot in the old model b and run pacman -Syu, boot in the new model b+ still fails with the error ** Unable to read file /dts/broadcom/bcm283x-rpi-other.dtb :|

Ah, sorry! I've just realized I'm running armv7 build :/
Code: Select all

on 4.16.0-1 (2nd of April) aarch64 and Pi3 B+ (plus) doesn't boot (the Pi3 B does, though)

I've even tried raspbian without any issue tbe be sure the board is actually OK, but in 64bit Arch it does not seem to be OK during boot.

Anything I could do to help? Any ETA? I was hoping for April 3rd zip to solve but it didn't.

Thanks in advance for any sort of help.

I went ahead and added this file:
https://github.com/raspberrypi/firmware ... b-plus.dtb
to /boot/dtbs/broadcom and renamed it to bcm283x-rpi-other.dtb

The pi boots just fine and i'm able to ssh to it after wireless starts.

Code: Select all
uname -a
Linux alarm 4.15.15-1-ARCH #1 SMP Sat Mar 31 21:00:14 MDT 2018 aarch64 GNU/Linux

Right ... so, that file makes it boot indeed, but nothing works in here.

• no ethernet network
• not a single USB port working

I haven't tried to put in a pre-configured Wi-Fi configuration but it looks to me things aren't really ready yet.

Thanks for the hint thought.

Try installing official Raspberry Pi kernel from AUR, instead of generic aarch64, which is provided by ArchLinuxARM. There is a report, that it is working find with 3B+ model with all hardware support.
