Hi Christian, I use the Orion O6 board daily, and I recently managed to successfully boot Debian on it.
Also, without CONFIG_ARCH_CIX enabled, the board probably wouldn't boot at all, as the DTB is only included when this configuration is selected. Reference: arch/arm64/boot/dts/cix/Makefile arch/arm64/configs/defconfig I have a question regarding your setup. When you built the kernel for testing, did you use the official Debian kernel build method, or did you use the upstream Linux kernel with a custom config and package it using deb-pkg? Regarding the GPIO support, I suspect it hasn't been fully merged into upstream yet. I am also curious about this, so I would like to CC the folks at CIX who have done great work to ask them directly: https://gitlab.com/cix-linux/cix_opensource/linux/-/commit/4231f6293fca28fd29b9cae8d1efed9947d6c0e1 Could you share the kernel .config file you used for testing so I can take a look?
