Hello @Malay, et.al, after submitting my PullRQ to the Armbian repo, I think it's best to cope first with the annotations I received from that. It complains about missing board photos, and some LLM generated blurb partly valid suggestions, partly not.
 
The current status of Armbian's Spacemit support does not make the RV2 board a good video player: GPU support is missing and I'm pretty unsure if it's possible to include the HW video encoding / decoding feature that is in the chip. Which is 4k@30 with diverse codecs according to the chip description PDF. I am glad, that X11 framebuffer video runs and I am unsure if I can proceed here b/c I am not a video / GPU / EGL / vulkan specialist.
 
Anyhow, thank you for the pointer to the Spacemit FAQ I did not recognize until now. While the PowerVR page from mesa3d states: "no IMG BXE-2-32" (https://docs.mesa3d.org/drivers/powervr.html), the respective Gitee repo contains closed-source BSD licensed Risc64 compiled shard objects (*.so), probably similar to the Nvida binary user space closed drivers that does the GPU support for the big videos cards. This may be worth a look, but as I wrote above, prio task is to bring the support into the Armbian tree.

Extract  the 7z file in the same folder as Armbian-unofficial_26.02.0-trunk_Luckfox-lyra-ultra-w_trixie_vendor_6.1.115_minimal.img
Then do:
dd if=uboot.img of=Armbian-unofficial_26.02.0-trunk_Luckfox-lyra-ultra-w_trixie_vendor_6.1.115_minimal.img bs=32k seek=1 conv=notrunc
 
Then you have an old Rockchip 2017.09 u-boot, my guess it that that shall work with 6.1.115
But you are the first one, the tester of it.
Also, I did a 32-bit rockchip edge kernel test build and I see no DTB file for Luckfox-lyra-ultra-w
That means it is not supported for mainline. At least it seems correct that one cannot build a working image now as legacy u-boot is not available anymore.
In theory, the 2025.10-rc4 u-boot might be such that you can get a mainlne edge rockchip kernel running, EFI booted maybe, but expect same strange errors or freezes.

@Malay delete patch/u-boot/u-boot-aw/99-dump-dram-controller-regs.patch. Using your compiler it causes a fatal error. The compiler I'm using it creates a warning. You don't need it anyways, it's for ram debug messages. I removed it from my repository,
