I'm returning from my travel, and start to poke again the board, and I'm very disappointed, my first objective is to use the box like a ThinClient, I have a big server at home with several VM. But after putting armbian running OK in the box the connection is very very very slow, I start to think it's an armbian problem, so, I return to Android and make some tests, and is even worse. It is impossible to use? No it is not, but you have several Lag for pointer and keyboard the image is OK no lag at all using 1920x1080, with 4k we have several image lagging. I'm using Ethernet, if I use wifi it's impossible to use, many lag in Android. So SAD, my plan will not gonna work, but I will keep poking the board just for fun. What is working: HDMI with sound (4k and bellow) Remote Controller Ethernet The clock (more or less) GPU What is not working: When you boot there is no image you need turn on the monitor in the exact moment or connect over network and restart X Some GPIO power (I see some errors in DMESG) WIFI (I believe is missing firmware or GPIO power) Bluetooth (detected, but when you try to enable disappear, RFKILL put in locked state) I don't know how to share my progress using github ( I only use git clone, I'm not a programmer), if someone share some documents or give some directions I can share without problem. I want to try to write armbian to emmc, I have the USB cable, but I don't know how to backup the android to restore in case of failure (and be sure, it will failure) Any help are welcome. Regards Panda

@Hacktarus13 I'm Currently travelling without access to the box, I'm returning next week, so I will start to it poke again. About the "opensource", I believe it's not opensource once the RK3528 was developed only for TvBox, even in the Rockchip site you didn't found any information about the processor or any board. I only found information in 2 sites about a press release of RK3528 where they say it's for TvBox, Even the Chinese have issues with the RK3528 for a lack of information. Best Regards Panda

News from the front... 🙂 HDMI 90% Operational now, Mali with lima drivers working well, now the Frame Buffer is working, so you can turn your monitor 10 seconds after the box. IR remote controller working (Unbelievable, but it's true) I'm struggling to make Wifi and bluetooth work, bluetooth is detected and appear on rfkill, but when you try to enable rfkill unblock and the interface disappear until your block again on rfkill, but cannot be enabled, any suggestion? Wifi is detected but rfkill not bring the device up, I get the erro -237 when iw try to set powermanagent on wireless-platdata. (No ideas of how to procced) What is making me crazy is the need to power the monitor 10 seconds of the box. I search over the internet, and try to change the eid on armbianArgs.txt, try to set framebuffer to 1024x768, but nothing work. Any advice? I will continue to poke the kernel and the dtb to try to solve the issues, so if someone can share some ideas or docs, please, this will help a lot. Regards Panda

Do you want update android ? or flash Armbian to emmc? I had a small chat with Lemfo and they do not share an Android image to reflash the device. I'm waitting my USB-A Male Male arrive, so I can dump the entire firmware from device, soon I get the dumped firmware I can share. what I have done is dump the emmc using ADB, but I'm not sure if it can be used to flash the device. If you want to try I can share the image. About flashing armbian to EMMC I do not recomend since it's not full working on SD Card yet and you can brick you device. Regards Panda

Hello People, I Bring to you the Lemfo HK1 RBOX K8S 4G/64G. This box came with Android 13 and can be rooted easy, follow some specs of the box: Processor: Rockchip RK3528 GPU: Mali 450 Memory: 4Gb (micron) Storage: 64Gb (eMMC 5.1 Samsung) Network: PHY Integrated stmmac-0:02 Driver RK630 100Mbps Wireless: 5G driver: rtl8822cs on gpio Bluetooth: 5.1 USB 3.0: 01 5Gbps USB 2.0: 01 HDMI: 01 TV-Out: 01 Power: 5v 2A Aliexpress link: Lemfo HK1 Rbox K8S What is Working: HDMI: partial (read bellow) Network: partial (read bellow) Bluetooth: no Wifi: no USB 3.0: yes Sound: yes over HDMI Obs: You need to use hinlink-ht2 image, but no wireless, nor ethernet, only HDMI work, and you need to turn on monitor around 15 seconds after turn on the TVBox I get the FDT from Android, and this FDT with hilink-ht2 images boot without HDMI, but with network, if you boot with hinlink-ht2 make the initial configs and start the desktop you can replace the rk-3528-hinlink-ht2.dtb with the android FDT and the box will boot, wait around 30 seconds and turn on the monitor and you have the HDMI and network working. I have build the image with xfce and include some drivers (mail450, RK630, rtl8822cs) and enable some DRM options (under test yet) I Have the Andoid boot partition dump, and other partions, I will share the files later (need some dropbox os gdrive to share) I have attached the Android.DTB and dmesg from android and armbian, if someone want take a look. Any help and sugestion will be great! Some pictures of the board: Lemfo-hk1rbox-k8s.dtb android_dmesg.log linux_dmesg.log linux-syslog

Hello people, I'm trying to compile armbian to run on my TV Box. If I use the image Hinlink ht2 I can boot without problem, but if I try to compile my version of Armbian, the tv box does not boot. I'm using the follow sintax to compile: ./compile.sh build BOARD=hinlink-ht2 BRANCH=legacy BUILD_DESKTOP=yes BUILD_MINIMAL=no DESKTOP_ENVIRONMENT=xfce DESKTOP_ENVIRONMENT_CONFIG_NAME=config_base EXPERT=yes KERNEL_GIT=shallow DEB_COMPRESS=xz I haven't the TTL to debug. What I already tryed: Burn the hinlink ht2 image to SD card and change the ROOT partition to my image (no work) Burn my image to SD card and copy the boot partition of hinlink to boot partition on SD Card (no work) Burn hinlink ht2 image and get the dtb and put on my image (no work) I'm accept any suggestion. Why I'm trying to compile ? The Ethernet is not working, on my board it uses the gmac0 and the hinlink ht2 uses gmac1 regards. Panda

I have the same box, but with 4/64 and I havent sucess to boot the image, maybe I'm missing someting, I put the SD card on the box and turn on, but after 10 minutes no HDMI screen, I havent yet connected by TTL. Can someone share an image of SD Card so, I can try? Or maybe write a step by step how to create the SD Card, I follow the guide of the forum, without success. Even multiboot does not boot.
