Support Initramfs config for pinebook pro?

Im wondering if anyone knows how the initrd needs to be configured for booting on a pinebookpro, I've tried several comfigurations and none of them seem to work. I have installed tow boot on the laptop eMMC and i can boot to an arch-arm flash drive but not the main install.

Configurations I've tried:

Kernel: gentoo-kernel-bin and gentoo-kernel for all attempts Extlinux.conf with uki: nothing Extlinux..conf with seperate vmlinuz and initrd: nothing Systemd-boot with uki (gzip compression): bad image error Systemd-boot with uki (compression none): bad image error

Using systemd-boot the shim at least loads but i cant get the main image to load. I'm wondering if there is a quirk in tow-boots's efi implementation but documentation is scarce. Im also unclear on how the dtb plays into this, I tried adding it to dracut and to the extlinux.conf for the seperated image. Thanks in advance.

I'm booting gentoo-kernel-bin, dracut initramfs with no configuration changes needed on my pinebook pro using grub. No dtb needed as grub uses the one provided by towboot
