I'm working on enabling secure boot on Orange Pi 4B. So far I was able to burn eFuses, sign rk loader, a trust image, and a uboot image. To extend secure boot chain to the Linux Kernel, I've enabled FIT_SIGNATURE in u-boot, and manually built FIT image (Linux Kernel, initramfs(initrd), and a kernel DTB). Now I want to add FIT image creation to the Armbian build system. What is the correct place/script to do it?

Hi, I have an issue with an USB device which is not detected; looking on other forum, it seems that additional modules shall be added: - cdc_acm,cdc_ether - rndis_host - rndis_wlan - usbnet I'm not able to load these using the modprobe cmd & checking loaded modules with lsmode cmd. I suspect that they are not part of the kernel. Any hint how to solve this, eventually recompile / install ? Thanks by advance, Samuel

Hi all, I have an Armbian installed on Orange PI 4B. I am trying to connect a flight controller to Orange PI 4B by using UART port. This board has a 40 pin header. I went to armbian-config, and enabled the UART1 and UART 4 which are available from armbian-config. I plug the UART port (to Pin 8 and pin 10) on the 40 pin header. Is that port UART 4? I am not sure. It does not work. I tried the debug port, but the Orange PI does not start up if something is plugged in to the debug UART port. The PIN layout https://wiki.adopisoft.com/doku.php?id=4.0.0:gpio_numbering The layout of the board is similiar to Orange PI One. I know the 5 V location by using the case fan. Thanks,

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?

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.

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.
