Hi,
As a newcomer to the Pi I am getting to grips with setting up as a wireless router. I've used Arch for ages on a server so tried to use it here but the bug at [url]https://archlinuxarm.org/forum/viewtopic.php?f=67&t=15422[/url] is still present in the latest aarch64 image.
I too have the Broadcom stepping C0 in my 2GB Raspberry Pi 4 Model B Rev 1.5 and was able to get it running by following advice at [url]https://archlinuxarm.org/forum/viewtopic.php?f=67&t=15422&start=20#p67299[/url]
I am going to try updating the install and hope none of the other bugs around mkinitcpio and bootloader hits me!
It might be helpful if the U-boot situation was mentioned in the installation guide as a potential issue to save alot of time in tracking down the cause.
Neil.
