Hi all, I would like to share my work on bringing Armbian to Rockchip RK3128 TV boxes. These boxes are quite old now, and I do not think they are especially common anymore. Still, I suspect a lot of people may have one lying around somewhere in a drawer, unused after Android updates stopped or the original firmware became too slow to care about. I also had several of them lying around at home, which is what pushed me to start this project in the first place. Since I could not find an RK3128 Armbian effort comparable to the RK322x one, I decided to try doing the port myself. Another important motivation was simply to reduce e-waste: if even some of these old boxes can be turned into usable Linux machines again instead of being thrown away, that already feels worthwhile to me. First and foremost, I want to send special thanks to @jock and @fabiobassa for their RK322x TV box work on this forum. Their work was the foundation that made this RK3128 effort much easier to start from. 1.

Current status At the moment I have two kernel lines: `4.4.194`, the older vendor-based line, which is already usable in practice `6.6.89`, the newer line, which allows these boxes to run a more up-to-date Armbian userspace What works in the current build: Custom U-Boot based on Rockchip U-Boot 2017.09 All four CPU cores, up to 1.2 GHz CPU frequency scaling and governors DRAM frequency control, both dynamic and fixed NAND, eMMC, SD card, and USB booting. The booting order is: USB >> SD Card >> NAND/eMMC (NAND and eMMC cannot be enabled at the same time because they share pins) OTG and EHCI/OHCI USB support Ethernet Wi-Fi support for SSV6051P, ESP8089, and several Realtek chips GPU acceleration UART1 and UART2, configurable Kernel `6.6.89` status in a bit more detail: CPU DVFS is stable after replacing the inherited/leakage-based OPP assumptions with a board-specific RK3128-safe table. The stable points I ended up using are `216 / 408 / 600 / 816 / 1008 / 1200 MHz` DMC / RAM devfreq works. In practice, simply enabling `dmc` works much better than I first expected, and boards can settle at different normal rates such as `396 MHz` or `456 MHz` GPU on `6.6.89` uses `Lima`, not the old Mali blob stack. That gives a maintainable Mesa/DRM path and hardware-accelerated OpenGL ES instead of depending on a legacy userspace blob VPU/video decode is still the weak point. I tried both `RKMPP` and `Hantro/V4L2` directions, but video processing is still limited, so I do not consider this a polished media-playback setup yet What does not work yet / known limitations: Bluetooth: not implemented or at least not validated, because I do not have a board with Bluetooth to test VPU / hardware video decoding is not in good shape yet SD card and SDIO Wi-Fi are currently using PIO mode on both kernel lines. This is slower than DMA, but stable enough for normal use 3. Image implementation I also made two RK3128 Armbian images based on existing RK322x Armbian images rather than building everything from scratch: Armbian 22.02: Based on the build provided by @jock, running kernel 4.4.189 Armbian 26.02: Based on the official Armbian build for rk322x, running kernel 6.6.89 In both cases, the idea was the same: keep the working RK322x Armbian userspace as a base, then replace the RK322x-specific parts with RK3128 ones, while the kernels themselves are based on Rockchip kernel sources. Compared with the original RK322x images, the RK3128 work mainly replaces or adds: boot.cmd / boot.scr changes so the boot flow can handle NAND and USB properly RK3128-specific Wi-Fi drivers and boot-time module loading logic rk3128-config a delayed Wi-Fi loader service RK3128-specific motd information the RK3128 kernel, DTB, and overlays For the `6.6.89` image specifically, there is some extra image-level cleanup and repackaging: remove the RK322x kernel / dtb / u-boot / BSP packages from the donor image pin those RK322x packages so they do not come back on upgrade install the RK3128 `6.6.89` Debian kernel packages rebuild the BSP package under the RK3128 name 4. Quick installation notes All required files are available from the releases page: The releaes page: https://github.com/chieunhatnang-personal/RK3128-Linux-SupportingScripts/releases Armbian 26.02 image: https://github.com/chieunhatnang-personal/RK3128-Linux-SupportingScripts/releases/download/kernel-6.6-armbian-26-v1.0/A26-release-20260415.zip Armbian 22.02 image: https://github.com/chieunhatnang-personal/RK3128-Linux-SupportingScripts/releases/download/kernel-4.4-armbian-22-v1.1/release-20260412.zip There are three installation layouts that are currently supported: 1. SD card only Pros: safest option, does not touch internal storage, easy to test and easy to remove, and if a board has an SD slot it can still be useful even when NAND/eMMC is completely dead Cons: slower than internal storage, and not every board has an SD slot Best for: first boot, testing, and boards where you want to keep the original Android install untouched 2. Full install to NAND / eMMC Pros: fastest and cleanest setup, uses the internal storage already present on the board Cons: overwrites the original Android install, and old NAND/eMMC may already be unreliable Best for: boards with healthy internal storage when you want a fully self-contained install 3. Hybrid install: bootloader on NAND / eMMC, rootfs on USB or SD card Pros: usually the most practical option for old TV boxes, works well when internal storage is only reliable enough for bootloader pieces, and can also help on boxes with problematic Android boot behavior Cons: more manual than the other methods, still depends on internal storage for the bootloader, and performance depends on the USB drive or SD card used Best for: boxes with weak or aging internal NAND/eMMC, or boxes where you want to avoid a full install to internal storage I describe each method in more detail below. 4.1. Install and boot from SD card Prepare: idbloader.img uboot.img trust.img rootfs.img Create an MBR partition table on the SD card, leave the first 16 MB empty, create one Linux partition, then write: idbloader.img to the raw device at seek=64 uboot.img to the raw device at seek=16384 trust.img to the raw device at seek=24576 rootfs.img to the first partition, not to the whole disk Example: DEV=/dev/sdX sudo parted -s "$DEV" mklabel msdos sudo parted -s "$DEV" mkpart primary ext4 16MB 100% sudo partprobe "$DEV" sudo dd if=idbloader.img of="$DEV" seek=64 conv=fsync sudo dd if=uboot.img of="$DEV" seek=16384 conv=fsync sudo dd if=trust.img of="$DEV" seek=24576 conv=fsync sudo dd if=rootfs.img of="${DEV}1" bs=4M status=progress conv=fsync sync I also provide a bootcardmaker.sh helper script in the same release directory to simplify this process. 4. 2. Full install to NAND / eMMC Prepare: rkxx_loader_vx.xx.xxx.bin parameter.txt uboot.img trust.img rootfs.img Then: Boot the board normally Connect a USB cable to the OTG port Open RKDevTool v2.69 In Advanced Function, erase the first 0x10000 sectors with Start LBA = 0x0 and Count = 0x10000 Press ResetDevice Wait for the board to return in MaskROM mode Go to Download Image Flash Loader, parameter, U-Boot, Trust, and rootfs 4. 3. Hybrid install: bootloader on NAND / eMMC, rootfs on USB or SD card This is the layout I use most often, and in practice it is probably the most useful one for old TV boxes. It is especially useful when internal NAND/eMMC is still good enough for Loader / parameter / U-Boot / Trust, but not reliable enough for a full root filesystem. A common symptom on these old boxes is that Android starts to boot and then hangs, or that the internal storage is simply too unreliable to trust with a full install. In this hybrid layout: Internal NAND/eMMC stores Loader, parameter, U-Boot, and Trust The root filesystem lives on USB or SD card Important: rootfs.img is a filesystem image, not a full disk image Write rootfs.img to a partition such as /dev/sdX1, not to the whole device Tools like BalenaEtcher are the wrong fit for this particular image layout Example: sudo dd if=rootfs.img of=/dev/sdX1 bs=4M status=progress conv=fsync sync 4.4. Post-install configuration After the board boots successfully, you can configure it either from the local console over HDMI or remotely over SSH if Ethernet is connected. Default login: user: root password: 1234 The first login will ask you to change the password. After that, run: rk3128-config This is the board-specific configuration tool for enabling and adjusting hardware features that may differ between RK3128 boxes. The most important options are: Wi-Fi chip selection RAM dynamic frequency: disabled by default. Enabling it can improve performance, but on some boards it may cause kernel hangs. If that happens, switch it back to disabled SD card storage enablement when booting from another device Display resolution OTG mode selection 5. Testing feedback is welcome If anyone here has RK3128 boards and wants to test, feedback would be very useful, especially for: Board photos and PCB markings Whether the board uses NAND or eMMC Boot method that works: SD, USB, NAND, eMMC Which Wi-Fi chip is present Serial logs, dmesg, and failure reports If there is enough interest and enough board coverage, I would be happy to keep improving this, cleaning it up further, and making it easier for other people to test. 6.

I had similar experience, can't remember exact numbers and versions etc as I already considered it not going to work, so did not take notes. Was on NanoPi-R6C, so same RK3588S at least. I think I already had put 'serial' as console in the EDK2 setup (is in eMMC for NanoPi-R6C), but not the older display option (GOP or so, forgot it). For my trial it was just the kernel, so instead of the a latest edge-rockchip64 that works all fine with EDK2 v1.1 in my setup, it was the generic UEFI-ARM64 kernel. You use a full image, so I think something is missing or not implemented yet. Also, my main assumption was (and is), is that only serial console is working for a CLI image. I have always a serial console cable available/prepared, although you need an extra other computer, but your OPi5 should simply run, just display is not initialized. You can look in dmesg, there might be a lot of HDMI debug/info, might also be the kernel and your HDMI monitor experience miscommunication, timing issue. I rebooted again with 7.0-rc3 rockchip64 and that worked again. Now I did some apt pinning so I can install/use Debian sid kernel (6.19.11 at the moment). That works the same as the armbian build 7.0-rc3 rockchip64. Also Opensuse Tumbleweed with its default 6.19 kernel works fine.
