No, the standard ISOs won’t boot due to the lack of RPI firmware, the images I posted you in that links and baked with RPI firmware, standard kernel and uboot, so it should boot fine on RPI but you won’t have RPI kernel " so some patches / features won’t be available ". This effort is aimed to have a generic image that can run on as many SoC as we can, some hardware is pretty great but they lack the enterprise linux images, and we are trying to bridge this gap. Give it a go, try installing it, then install kernel 6, I think this should work 🙂 let me know! ---

Sounds interesting, what is the difference between the `rk3399` and `sda` images you linked, and which one should I use? ---

the rk3399 is for rock chips “rockpro64” boards, images are the same, the rk3399 has uboot images dd-ed into them, use the generic one, [https://rockyrepos.gnulab.org/images/Rocky-9.1-aarch64-generic-Minimal-sda.raw.tar.gz](https://rockyrepos.gnulab.org/images/Rocky-9.1-aarch64-generic-Minimal-sda.raw.tar.gz) and make sure to check the readme ---

I tried using the generic one now, downloaded, verified checksum, dd’d it onto my SD card, but it wont boot successfully. I can see that it passes uboot, the logo is shown in the upper right corner, and then it looks like Rocky starts booting up, but then after a bunch of startup output the screen just goes black and I never reach the login prompt. ---

Well the blank screen is expected and takes a bit of time, some people did complain that sometimes the HDMI won’t get back any signal depend on your screen, wait like 1 minute, then try to unplug and replug the HDMI or SSH into the box, just ran a fresh test on RPI4 model b and it works fine. Also installed the kernel-ml from elrepo but that won’t boot, I guess there might be some patches needed like the generic LTS kernel. ---

Is that to say that I just need to wait for the next LTS kernel release upstream, or do you mean that the generic image you linked from gnulab needs to be patched? ---
