Please try to update the Raspberry Pi firmware or at least provide the complete dmesg.

I found here that the uboot-raspberrypi PKGBUILD is out of date with the uboot source and the .dtb's getting pulled in. The uboot source is out of the -rc stage but that did not fix the usb issue. What worked was replacing the latest related .dtb's in /boot with the ones from here:

darksky, do I just configure an AARCH64 system and replace the .dtb files in /boot with the ones from your link? Sorry, not very experienced with RPI and dtb files, etc. My EEPROM is up to date (stable).

That is what I did. I did not want to take the time to rebuild the raspberry pi uboot package again when I was testing. Then reboot when done. I did rebuild the uboot package with the updated uboot source from denx.de/pub/u-boot but I am thinking that was not the issue as I still had no working usb ports afterwards. Actually I only copied 1 (bcm2711-rpi-4-b.dtb) as the pi4 board was the only one I was using. The new bcm2711-rpi-4-b.dtb made it start working.

Thank you thank you! I simply replaced the bcm2711-rpi-4-b.dtb file in /boot with the one from your link and rebooted. It worked, I now have USB and all 8gb RAM. :)

Still failed.

I follow the guide https://archlinuxarm.org/platforms/armv ... berry-pi-4

After "sync", I do:

mv root/boot/* boot
sed -i 's/mmcblk0/mmcblk1/g' root/etc/fstab
cp ~/Downloads/bcm2711-rpi-4-b.dtb boot
umount boot root

Then boot the board, and it shows a colorful square image.

Thanks so much darksky, it worked!

I have an rpi4 with 8 GB RAM and followed the instructions at https://archlinuxarm.org/platforms/armv ... berry-pi-4. It would bring me to the login but I couldn’t type anything after trying multiple keyboards. After copying bcm2711-rpi-4-b.dtb from https://github.com/raspberrypi/firmware ... aster/boot into my boot partition, it works :)
