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,
