Iam a new user to this forum and tv box. As iam interested to run Linux in stb I bought one. Hope the senior members will guide me in the right direction. Pics of my tv box. Device picture Pcb Front Pcb back Just now got shipment from bangood the h96max Android tv box with rk3318 chip. First thing after booting Android from the box, is to open the box took the pics of the pcb front and back. I have been following this forum and noted the mistakes in general users, and not taking backup and difficult in finding pads for maskrom. 1. Where is the pads to short for maskrom mode. 2. Though I can try with different dtb, is this board already a familiar one. 3. Can I boot from sdcard without erasing emmc.
Greetings, After receiving an "mx10 pro 4k" 4gb 32gb I tried booting armbian on it. Strangely, after trying multiple images, dtbs I couldn't boot into armbian no matter what. Becoming frustrated I proceed to open the box which surprised me: both the dusty packaging and PCB advertise an rk3328, but after removing the heat sink I found out that it actually contains an rk3318 as adb and android warned me. https://imgur.com/a/Hv1Qlw3 Not only did I get "scammed" (the box still works on android, and the average user wouldn't even notice), but now I seem to own an unknown box as it seems I can't trust the seller for anything they said. So here I am, trying to reverse engineer the box, it doesn't contain apparent I2C or any other serial port but I successfully connected with adb root, I would like to extract the blobs but I never did such a thing before with android so help will be appreciated
DISCLAIMER (PLEASE READ): everything you can find in this thread (binaries, texts, code snippets, etc...) are provided AS-IS and are not part of official Armbian project. For this reason not people from Armbian project nor myself are responsible for misuse or loss of functionality of hardware. Please don't ask about support or assistance in other non-community forums nor in the official Armbian github repository, instead post your questions in this thread, in the TV Boxes forum section (hardware related) or in the Peer-to-peer support section (general linux/software related). Thank you! This thread is to give stable and mature long-term range support to rk3318/rk3328 found in many tv boxes in Armbian project as Community Supported Configuration (CSC). The current work is in early stages, it may or may not work for you; if and when it will be considered mature enough, it will be hopefully merged into Armbian master, but in the meantime it lives on my personal fork on github -> here <- Important notes: is just a personal opinion, but apparently widely supported, that rk3318 chip is not an official rockchip part. They probably are scrap rk3328 parts which have not passed conformance tests but are sold anyway to tv boxes manufacturers. They don’t reach the same operating frequency of the rk3328, have much higher leakage currents (and thus higher temperatures) and often the boards they are installed on are low quality with low quality components, in fact a very very common issue is the eMMC failure due to bad parts and bad soldering. So said, I personally suggest not to buy any rk3318 tv box, but instead find a properly supported SBC (Single Board Computer) if you need a reliable product. In the unfortunate case you already have such product, this thread may help you have some fun with them. What works: • Works on RK3318 and RK3328 TV boxes with DDR3 memories • Mainline u-boot • Mainline ATF provided as Trusted Execution Environment • All 4 cores are working • Ethernet • Serial UART (configured at stock 1.5Mbps) • Thermals and frequency scaling • OTG USB 2.0 port (also as boot device!) • EHCI/OHCI USB 2.0 ports • MMC subsystem (including , SD and sdio devices) • Hardware video acceleration (fully supported via RKMPP on legacy kernel, support via hantro and rkvdec kernel driver on mainline) • Various WIFI over SDIO are supported • Full acceleration on legacy kernel and mainline kernel. Mainline has lima driver compiled in but X11 is albeit slow - you are still free to compile and install mali kernel driver on mainline yourself. • U-boot boot order priority: first the sdcard, then the USB OTG port and eventually the internal ; you can install u-boot (and the whole system) in the internal and u-boot will always check for images on external sdcard/USB first. Unbrick: Technically, rockchip devices cannot be bricked. If the internal flash does not contain a bootable system, they will always boot from the sdcard. If, for a reason, the bootable system on the internal flash is corrupted or is unable to boot correctly, you can always force the maskrom mode shorting the clock pin on the PCB. Here there is the procedure (for rk322x, but on rk3318 is the same), but you can also google around if you get stuck on a faulty bootloader, the technique is pretty simple and requires a simple screwdriver. There are however some unfortunate cases where shorting the clock pin is difficult or impossibile, like BGA chips with no exposed pins. In those cases pay double attention when burning something on the internal flash memory and always test first the image booting from the sdcard to be sure it works before burning anything in internal flash. This is a list of posts where forum users have been able to spot the eMMC clock pin to trigger the maskrom mode: Ninkbox N1 Max RK3318 by @enigmasphinx Partecipation and debugging: If you want to partecipate or need help debugging issues, do not hesitate to share your experience with the installation procedure of the boxes. In case of issues and missed support, provide as many as possible of these things is very useful to try and bring support for an unsupported board: upload the device tree binary (dtb) of your device. We can understand a lot of things of the hardware from that small piece of data; dmesg and other logs (use armbianmonitor -u that automatically collects and uploads the logs online) attach a serial converter to the device and provide the output of the serial port; a link to the original firmware (you can do a full backup with the Multitool); some photos of both sides of the board. Some details of the eMMC, DDR and Wifi chips are also useful Multimedia: If you need multimedia features, like OpenGL/OpenGL ES acceleration, hardware accelerated Kodi, ffmpeg and mpv you can take a look to this post Installation (via SD card): Building: You can build your own image follow the common steps to build armbian for other tv boxes devices: when you are in the moment to choose the target board, switch to /TVB/ boards and select "rk3318-box" from the list. Development images: Armbian 21.11 - Debian Bullseye minimal - mainline kernel 5.14.14 - Download from here - Build date: 2021-10-22 Armbian 21.11 - Ubuntu Hirsute desktop [xfce] - mainline kernel 5.14.14 - Download from here - Build date: 2021-10-22 Armbian 21.05 - Debian Buster minimal - legacy kernel 4.4.213 - Download from here - Build date: 2021-04-16 (not available) Manual kernel upgrade: In case you want to upgrade to the latest kernel on a existing installation, deb packages are available here. Download all the deb packages in an empty directory and then install with the following command: sudo apt install ./*.deb Multitool: Multitool - A small but powerful image for RK3318/RK3328 TV Box maintenance. Download it from here Quick installation instructions on eMMC: Build or download your preferred Armbian image and a copy of the Multitool; Burn the Multitool on an SD card; once done, place the Armbian image in images folder of the SD card FAT partition; Plug the SD card in the TV box and plug in the power cord. After some seconds the blue led starts blinking and the Multitool appears; OPTIONAL: you can do a backup of the existing firmware with "Backup flash" menu option; Choose "Burn image to flash" from the menu, then select the destination device (usually mmcblk2) and the image to burn; Wait for the process to complete, then choose "Shutdown" from main menu; Unplug the power cord and the SD card, then replug the power cord; Wait for 10 seconds, then the led should start blinking and HDMI will turn on. The first time the boot process will take a couple of minutes or more because the filesystem is going to be resized, so be patient and wait for the login prompt. On first boot you will be asked for entering a password for root user of your choice and the name and password for a regular user Run rk3318-config to configure the board specific options Run armbian-config to configure timezone, locales and other personal options Run apt-mark hold linux-image-edge-rockchip64 linux-dtb-edge-rockchip64 to avoid the upgrade of kernel with the armbian official one, since it still does not contain rk3318 Congratulations, Armbian is now installed! Despite the procedure above is simple and reliable, I always recommend to first test that your device boots Armbian images from SD Card. Due to the really large hardware variety, there is the rare chance that the images proposed here may not boot. If a bad image is burned in , the box may not boot anymore forcing you to follow the unbrick section at the top of this post. Quick installation instructions to boot from SD Card: If you are already running Armbian from eMMC, skip to the next step. Instead if you are running the original firmware you need to first erase the internal; to do so download the Multitool, burn it on an SD Card, plug the SD Card and power the TV Box. Use "Backup flash" if you want to do a backup of the existing firmware, then choose "Erase flash" menu option. Build or download your preferred Armbian image; Uncompress and burn the Armbian image on the SD Card; Plug the SD Card in the TV Box and power it on; Wait for 10 seconds, then the led should start blinking and HDMI will turn on. The first time the boot process will take a couple of minutes or more because the filesystem is going to be resized, so be patient and wait for the login prompt; On first boot you will be asked for entering a password for root user of your choice and the name and password for a regular user Run rk3318-config to configure the board specific options Run armbian-config to configure timezone, locales and other personal options, or also to transfer the SD Card installation to internal ; Run apt-mark hold linux-image-edge-rockchip64 linux-dtb-edge-rockchip64 to avoid the upgrade of kernel with the armbian official one, since it still does not contain rk3318 Congratulations, Armbian is running from SD Card! A note about boot device order: With Armbian also comes mainline U-boot. If you install Armbian, the bootloader will look for valid bootable images in this order: External SD Card External USB Stick in OTG Port Internal Critics, suggestions and contributions are welcome! Credits: @fabiobassa for his ideas, inspiration, great generosity in giving the boards for development and testing. The project of bringing rk3318 into armbian would not have begun without his support! @hexdump for his precious support in early testing, ideas and suggestions @MX10.AC2Nfor his patience in testing mxq-rk3328-d4 board support All the rockhip64 maintainers at Armbian project who have done and do most of the work to support the platform
