  1. Have an OPi 4B with installed Armbian (Armbian_21.05.1_Orangepi4_buster_legacy_4.4.213_xfce_desktop.img from here) which is working perfectly. HUGE thanks for that. So i wanted to try images with mainline kernel and found that none of XFCE desktop images from the archive can correctly output HDMI signal for my screen, maximum i could achive was compressed and flickering image using method from docs (editing /etc/X11/xorg.conf.d/40-monitor.conf). by default there are no modes in /sys/class/drm/card0-HDMI-A-1/modes in mainline images and in legacy one there are two: 1280x800p60 and 1280x800p57. EDID is there in both images. And if i set resolution via /etc/X11/xorg.conf.d/40-monitor.conf in mainline i can't change it to anything via xrandr because "Configure crtc 0 failed". on the latest mainline image (Armbian_22.08.10_Orangepi4_jammy_current_5.15.76_xfce_desktop.img) i was able to get normal resolution doing the following : 1. edit /etc/X11/xorg.conf.d/40-monitor.conf from console like below: Section "Monitor" Identifier "HDMI-1" Modeline "1280x800_try4" 75 1280 1290 1300 1500 800 805 810 823 +hsync -vsync Option "PreferredMode" "1280x800_try4" EndSection this gets me a compressed screen after reboot. 2. then in terminal: xrandr --newmode "1280x800_60.00" 83.46 1280 1344 1480 1680 800 801 804 828 -hsync +vsync xrandr --addmode DP-1 1280x800_60.00 xrandr --output DP-1 --mode 1280x800_60.00 xrandr --output DP-1 --crtc 1 after that image on HDMI suddenly becomes normal but still no resolution changes can be applied to HDMI Any chances for easy workaround here?
  2. Hello Folks, Good day. I hope you're doing great. I'm trying to make the OrangePI 10.1 inch MIPI DSI (product page) work on the most recent (mainline) Armbian build. Building the image using the OrangePI source repositories and following the instructions on OPi4B manual enables the LCD and touch, However, my intention is to make the LCD + Touch work on the most recent Armbian Focal (mainline). I've setup my Armbian build env but I cannot see to find how to enable this MIPI screen on any build options. Here's the instructions from Page #20 of OPi 4B manual: Download the Linux source code and make the following changes in dts --- a/arch/arm64/boot/dts/rockchip/rk3399-orangepi-lcd.dtsi +++ b/arch/arm64/boot/dts/rockchip/rk3399-orangepi-lcd.dtsi @@ -40,12 +40,12 @@ max-x = <800>; max-y = <1280>; tp-size = <101>; // <911> for 8 inch // <101> for 10 inch - status = "disable"; + status = "okay"; }; }; &dsi { - status = "disable"; + status = "okay"; panel@1 { compatible = "simple-panel-dsi"; reg = <0>; That specific file doesn't exist on the Armbian build directory tree. I'm not familiar enough with the dts and dtsi files to be integrating it. I've been searching the forum for answers but, so far, I'm not able to make it work. I'm looking for help on enable it and appreciate any pointers or guidance that can help make the LCD + Touch work on a mainline kernel version. I linked some dts files from the OrangePI source repository that "might" help. I'm thankful for any help. Thank you.
  3. I have an orangepi 4b rk3399 board and I am not able to boot with an armbian image above kernel 5.0 . until kernel 4.4.2.1.3 it boots but no usb port works and if you update the kernel it doesn't boot anymore. Can someone help me.
  4. I use orangepi 4B. I use console Ubuntu with kernel 4 from Xunlong And my CPU Temperature (by htop) is about 70°C I use console armbian with kernel 5 (Governor = powersave). And my CPU Temperature is about 79°C Why so? I want to get 70°C in armbian too.
  5. Hello ! i'm trying to enable the SPI interface on a OrangePi4B board using Focal latest stable build, so I edit `/boot/armbianEnv.txt` to add these lines : overlays=spi-spidev param_spidev_spi_bus=0 But after rebooting, I'm unable to access to the board anymore (No IP address is assigned to the board by the DHCP server). What's wrong ? Is there any additionnal steps ? FYI, I also tried to enable SPI using armbian-config tool but it doesn't work neither. As this tool doesn't even specify the `param_spidev_spi_bus` parameters which is required according to the overlay README.
  6. Hi all, Happy New year! I have a 7" IPS 1024X600 touch screen that I finally got it to work on Raspberry PI with the following configuration: hdmi_cvt:1=1024 600 60 3 0 0 0 # uncomment to force a specific HDMI mode (this will force VGA) hdmi_group:1=2 hdmi_mode:1=87 hdmi_drive:1=2 The product link is here: https://www.amazon.com/dp/B07VNX4ZWY/ When I plug this item into Armbian, the screen just flashes ON and OFF, but for some reason, the login screen works with about 1" black border on either side. When I type in log in password, the screen starts flashing again. I tried cvt 1024 600 60, but nothing changed. This screen works fine with Android that comes with Orange PI 4B. I think configuration somewhere is missing or wrong. Also, what touch screen keyboard should I use? I tried to install Florence Virtual Keyboard, and I don't think it could start with Armbian desktop. Thanks for helping out.
  7. Hello Folks, good day. I have a project where I need to use a OrangePi 4B and couple of hardware pieces connected to it. I'm having trouble putting together a Linux image where I have, at least the minimum functions required for the project working. I need an image where these items below are enable/working: - SPI - I2C - GPIO - PWM - 10.1 MIPI DSI LCD + TOUCH (available here) - MIPI CSI Webcam (OV13850) - 3D Acceleration (WebGL / OpenGl) using the Mali t860 - Bluetooth - Wifi Ideally, I would like to use the most recent Focal mainline kernel, but a legacy image will also be fine. I've been spending a lot of time building and testing many different images, I tested all available on the OrangePi website and the ones pre built on the Armbian too. Some peripheral works on some images, some others not, etc. I also built several images myself but, up to the moment I was not able to make a single one with all the features above working. I'm looking for help from the experts here on suggestions/guidance on how to accomplish the task of having a single, (preferably updated) linux image working on this project. Appreciate the help. Thank you.
