Man I have been trying to get guix to boot on my pinebook for years and the closest I ever got was successfully building a stripped down version of the installation image natively using qemu-binfmt

It was able to boot and even install to the emmc and boot again but when I tried to guix system reconfigure it bit the dust.

Now it “hangs” but a serial console reveals somehow the co-processors are misconfigured and the scheduler is scheduling tasks but they are timing out. Some hunting on the forums showed me somehow I need to disable the smaller cores and just boot u-boot with the main 4 and let linux handle initialization but I haven’t progressed on this front for a few weeks.

Here is my os definition for what it’s worth.

(define pinebook-os
  (operating-system
    (inherit pinebook-pro-barebones-os)
    (host-name "voyager")
    (timezone "UTC")
    (locale "en_US.utf8")

    (bootloader (bootloader-configuration
		 (bootloader u-boot-pinebook-pro-rk3399-bootloader)
		 (targets '("/dev/mmcblk2"))))

    (kernel linux-libre-lts)

    (kernel-arguments (list "iommu=soft"))

    (packages (cons* cryptsetup
		     emacs
		     emacs-exwm
		     st
		     %base-packages))

    (file-systems (cons*
		   (file-system
		    (device (file-system-label "ROOT"))
		    (mount-point "/")
		    (type "btrfs"))
		   (file-system
		     (mount-point "/boot")
		     (device (uuid "E6FF-F73A" 'fat32))
		     (type "vfat"))
		   %base-file-systems))

    (users (cons* (user-account
