  1. Working on CPU frequencies, the armbian image limit max cpu freq to 1.3 GHz. Neverthless the box has been sold as 1.5Ghz, so I was asking myself why should I lose some calculation power. After few serching around I found that the box can run stable at 1.4GHz with 1.35V voltage. Using armbian-config, the dtc can be modifed: opp-1200000000 { opp-hz = <0x00 0x47868c00>; opp-microvolt = <0x124f80>; clock-latency-ns = <0x9c40>; status = "okay"; }; opp-1296000000 { opp-hz = <0x00 0x4d3f6400>; opp-microvolt = <0x137478>; clock-latency-ns = <0x9c40>; status = "okay"; }; opp-1392000000 { opp-hz = <0x00 0x52f83c00>; opp-microvolt = <0x149970>; clock-latency-ns = <0x9c40>; status = "okay"; }; I also tested 1.5GHz but temperature raise wuickly when stressed (up to 90°C) and started to have some unstable unexpected behaviour, so I stick to 1392 MHz with good results.
  2. Moved the whole system from sd card to internal emmc. (* printscreen from Helios64, just for sample https://wiki.kobol.io/helios64/install/transfer/) Step 1 - Run Armbian Configuration Utility Step 2 - Select Install Menu Step 3 - Select Boot from eMMC - system on eMMC Step 4 - Confirm that the process will erase data on eMMC Step 5 - Select filesystem type for eMMC Step 6 - Wait for transfer process to complete Step 7 - Final step, install u-boot before poweroff #install u-boot for your system sudo apt install linux-u-boot-rk3318-box-edge cd /usr/lib/linux-u-boot-edge-rk3318-box/ #Write tpl+spl at 64th sector sudo dd if=idbloader.img of=/dev/sdc seek=64 #Write U-Boot proper at 16384 sector sudo dd if=u-boot.itb of=/dev/sdc seek=16384 sync Power off. Remove sd card. Boot from internal emmc successfully!
  3. RK3318 board (x88 pro 10) Kernel: 6.6.2-edge-rockchip64 Ubuntu Jammy 22.04.3 LTS Vidoe hardware acceleration working. Clock and leds working using the OpenVFD service See details here if interested:
  4. Updated to kernel 6.6.2-edge-rockchip64 Need to recompile openvfd driver, had to modify openvfd_drv.c. Patch attached. patch linux_openvfd/driver/openvfd_drv.c < openvfd_drv.c.patch openvfd_drv.c.patch
  5. About OpenVFDService, had to study and understood that led cannot be triggerd without an userspace program with custom made functions. https://github.com/arthur-liberman/linux_openvfd/blob/master/OpenVFDService.c So decided to mod directly the OpenVFDService to include POWER, LAN and WIFI led. My setup is: POWER always on when the box is running LAN on when lan cable connected The OpenVFDService source is attached, and hereunder a short explanation of the mod. // display is controlled by just 7 words 0 -> lan, power, colon, wifi leds on/off 1 -> hour +1 2 -> hour 3 -> minute +1 4 -> minute 5 -> unused = 0 6 -> unused = 0 7 -> unused = 0 memset(wb,0x00, sz); // set all to 0 // byte 0 mapping wb[0] |= 0b01100000; // wifi wb[0] |= 0b00000100; // power wb[0] |= 0b00010000; // colon wb[0] |= 0b00001000; // lan // mod for time and colon wb[0] |= 0b00010000 & (data.colon_on << 4); // colon blink original function wb[1] = char_to_mask(data.time_date.hours/10); // hour+1 wb[2] = char_to_mask(data.time_date.hours%10); // hour wb[3] = char_to_mask(data.time_date.minutes/10); // minutes+1 wb[4] = char_to_mask(data.time_date.minutes%10); // minutes //write to display ret = write(openvfd_fd, wb, sz); LAN connected was pretty straightforward: // check ethernet char buf_eth[1]; int fd = open("/sys/class/net/eth0/carrier", O_RDONLY); if (fd < 0) { perror("Open /sys/class/net/eth0/carrier failed.\n"); return; } else{ // read from fd read(fd, buf_eth, 1); close(fd); } // set display LAN led if ( buf_eth[0]=='1' ){ wb[0] |= 0b00001000; // lan } About Wifi led, my box do not use wifi, so decided to link this function the the IR remote receiver. Led on when a IR signal is received. // create thread for LIRC dev listening in main ret = pthread_create(&lirc_id, NULL, lirc_thread_handler, &setup); //New thread - listen ot lirc device for IR signal void *lirc_thread_handler(void *arg) { lirc_loop(); pthread_exit(NULL); } // IR read loop and set flag void lirc_loop(){ char buf[8]; //printf("Start lirc wait signal:\n"); while(sync_data.isActive) { //printf("DEBUG new thread created!\n"); if ( !gotIRchar ){ // check lirc dev int fd = open("/dev/lirc0", O_RDONLY); if (fd < 0) { perror("Open /dev/lirc0 failed.\n"); return; } // read from fd read(fd, buf, sizeof(buf)); //printf("DEBUG read complete %i\r",sizeof(buf)); close(fd); if (buf[0] > 0){ //printf("Ir receive: %s\n",buf); gotIRchar = true; // set IR received FLAG } } } } // check flag and set display WIFI led if ( gotIRchar ){ wb[0] |= 0b01100000; // wifi gotIRchar = false; } OpenVFDService.c
  6. Update, still wokring on OpenVFD, in armbian ubuntu jammy the front display shows only clock. Using test mode I can succesfully see all symbols lit up: OpenVFDService -t I can also manually trigger the 3 symbols with: echo eth > /sys/class/leds/openvfd/led_on echo wifi > /sys/class/leds/openvfd/led_on echo power > /sys/class/leds/openvfd/led_on Neither wifi led is linked to wifi status, nor power, nor lan.
  7. No way to have kodi acceleration working yet. In the meanwhile I have been studying the front LCD, which was black [SOLVED] 1. Install OpenVFD #install kernel headers (skip if already installed) sudo apt-get install linux-headers-`uname -r` # download the sources: git clone https://github.com/arthur-liberman/linux_openvfd # change the directory cd linux_openvfd/driver # edit the Makefile # change the line KERNELDIR = ../../../ # to this: KERNELDIR = /lib/modules/$(shell uname -r)/build # create a symlink to correct System.map in this KERNELDIR - in my case: # /lib/modules/6.1.7-rockchip64/build/System.map -> /boot/System.map-6.1.7-rockchip64 # compile the driver (in openvfd/driver): make -j4 # install module sudo make modules_install # load module modprobe openvfd 2. Install OpenVFDService cd linux_openvfd make -j4 OpenVFDService sudo cp OpenVFDService /usr/sbin/ 3. Update dts using armbian-config add at the end: openvfd { compatible = "open,vfd"; dev_name = "openvfd"; status = "okay"; }; reboot and you will find new device-tree in /proc/device-tree/open-vfd 4. Create openvfd.service in /lib/systemd/system/openvfd.service or download attached file [Unit] Description=OpenVFD Service ConditionPathExists=/proc/device-tree/openvfd/ [Service] ExecStart=/bin/sh -c '[ `cat /proc/device-tree/openvfd/compatible` = "open,vfd" ] && /sbin/modprobe openvfd; /usr/sbin/OpenVFDService' ExecStop=/bin/kill -TERM $MAINPID ExecStopPost=-/usr/sbin/rmmod openvfd RemainAfterExit=yes [Install] WantedBy=basic.target create VFD config in /etc/modprobe.d/openvfd.conf options openvfd vfd_gpio_clk="4,0x13,0" options openvfd vfd_gpio_dat="4,0x16,0" options openvfd vfd_gpio_stb="4,0x12,0" options openvfd vfd_chars="4,0,1,2,3" options openvfd vfd_dot_bits="0,1,3,2,4,5,6" #ID Display type #0x03 A display like on the A95X R2 (or the Abox A1 Max). <-- #.2 Reserved - must be 0. #.3 flags #.4 0 - > FD628 and compatible controllers options openvfd vfd_display_type="0x03,0x00,0x00,0x00" enable service and start (this will autoload the kernel module openvfd sudo systemctl enable openvfd sudo systemctl start openvfd After this the system clock will successfully show up on the front LCD openvfd.service
  8. have 3 scenarios: perfetct when launching mpv from terminal with gpu-context=drm some frame scattering when using mpv windowed in X11 too many frame dropped with mpv -fs in X11 perfect with mpv -fs in Xwayland I don't like wayland too much, and I would prefer X11, but seems to have no choice.
  9. So after more the one week working on legacy kernel, I decided to switch to mainline kernel (now using 6.6.2-edge-rockchip64). Removed the liujianfeng1994 repository and installed packeges of the v4l2request repository. Regarding this bug: bug: Lima driver (Mali 400/450) shows a red/pink tint when video is played in X11/Wayland (see https://github.com/mpv-player/mpv/issues/12968) I found that forcing MESA to a different GL core profile can solve the pinkish problem: export MESA_GL_VERSION_OVERRIDE=3.2COMPAT export MESA_GLSL_VERSION_OVERRIDE=320 mpv your-video.mkv Now I have HW accelerated video with mpv . Still have tu study how to get Kodi acceleration working.

  11. So after having hw decode in gstreamer, still kodi not using HW codec. The option to use DRM in settings/player is missing,so decided to rebuild kodi on my own, from repository : https://launchpad.net/~liujianfeng1994/+archive/ubuntu/rockchip-multimedia/+packages Install the Debian SDK sudo apt install devscripts build-essential Go to page https://launchpad.net/~liujianfeng1994/+archive/ubuntu/rockchip-multimedia/+packages, From this page, copy the url to the the changes file from the top link marked (changes file). https://launchpadlibrarian.net/682100344/kodi_20.2+dfsg-4+gles_source.changes From a temporary working directory, run: dget --extract --allow-unauthenticated https://launchpad.net/~liujianfeng1994/+archive/ubuntu/rockchip-multimedia/+files/kodi_20.2+dfsg-4+gles_source.changes This command will download sources and create the source tree hereunder: kodi-20.2+dfsg ├── addons ├── cmake ├── debian ├── docs ├── lib ├── libdvdnav-embedded ├── libdvdread-embedded ├── LICENSES ├── media ├── obj-aarch64-linux-gnu ├── project ├── repo-resources-embedded ├── system ├── tools ├── userdata └── xbmc Install the Package build-dependencies and Build the Package cd kodi* sudo mk-build-deps --install --remove As long as this completed with no errors, the package is ready to build. dpkg-buildpackage --build=binary --no-sign Be prepeared.. this will create a 8.5 GB folder with all kodi packages, if you are able to go to the end of Make process!

Kodi starting proprely, but DRM Prime decoder option missing. Studing in this problem, I suppose that kodi should run on GDM/Wayland, instead my configuration works on X11/Xfce. PROBLEM Now trying to setup wayland, i have the login screen with gdm3, but after successfull authentication nothing happens -> the systems come back to login screen.

  12. of course you are right, as stated above I installed your repository for v4l2request hardware video decoding but I got stuck with the lima bug, and the pinkish videos do not satisfy me enough So after having hw decode in gstreamer, still kodi not using HW codec. The option to use DRM in settings/player is missing,so decided to rebuild kodi on my own, from repository: https://launchpad.net/~liujianfeng1994/+archive/ubuntu/rockchip-multimedia/+packages
  13. Good results with legacy kernel on Jammy! Temporarly abandoned the mpv configuration and started working on gstreamer. Now able to play and decode succesfully a 1080p video using gstreamer and hw decoder, using the following command: //install missing gst plugin apt-get install gstreamer1.0-plugins-bad //play mkv h264 file gst-launch-1.0 filesrc location=test_video.mkv ! matroskademux name=demux demux.audio_0 ! decodebin \ ! queue ! audioconvert ! pulsesink device=0 demux.video_0 ! queue ! parsebin ! mppvideodec width=1920 height=1000 ! rkximagesink Note: do not install and update packages from this repository, otherwise the X11 server will not start anymore, due to a probably buggy mesa or mali driver. sudo add-apt-repository ppa:liujianfeng1994/panfork-mesa This would overwirte the libraries hereunder: Setting up libgbm1:arm64 (23.0.4-0ubuntu1~22.04.1) ... Setting up libglapi-mesa:arm64 (23.0.4-0ubuntu1~22.04.1) ... Setting up libllvm15:arm64 (1:15.0.7-0ubuntu0.22.04.3) ... Setting up libgl1-mesa-dri:arm64 (23.0.4-0ubuntu1~22.04.1) ... Setting up libegl-mesa0:arm64 (23.0.4-0ubuntu1~22.04.1) ... Setting up libglx-mesa0:arm64 (23.0.4-0ubuntu1~22.04.1) ...
  14. yes the box is the one linked above. Now doing some test with legacy kernel on ubuntu jammy. Used armbian-config to switch to legacy kernel: 4.4.213-legacy-rockchip64 Then following instructions on: https://launchpad.net/~liujianfeng1994/+archive/ubuntu/rockchip-multimedia sudo add-apt-repository ppa:liujianfeng1994/rockchip-multimedia sudo apt update sudo apt dist-upgrade sudo apt install rockchip-multimedia-config then installed kodi from repository, seems using HW codec RKMPP but the result is bad, many frames dropped and color drift to blue. Will do some more tests.
  15. Installed the suggested package, and installation was flawless. Now able to play hw accelerated video with mpv: mpv --vo=gpu --hwdec=drm --gpu-context=x11egl --gpu-hwdec-interop=drmprime <your-video.mp4> but confirm the bug described here: Lima driver (Mali 400/450) shows a red/pink tint when video is played in X11/Wayland (see https://github.com/mpv-player/mpv/issues/12968) Using drm gives error # Hardware decoded video running on bare terminal, presentation via EGL mpv --vo=gpu --hwdec=drm --gpu-context=drm --gpu-hwdec-interop=drmprime <your-video.mp4> Able to play video with option: --drm-atomic=no but too many frames dropped and video scattering
