  1. Unplugged the Tinker Board, took a break for several hours, established a serial port session to FTDI serial port from my laptop, then plug in TB again. And I can see the serial port output. Not sure what mattered. But now everything works.
  2. In order to review the Tinker Board boot logs via serial console, I set up armbianEnv.txt to get the logs. But Armbian didn't output anything. Can anyone tell me what is wrong? As long as I reviewed boot.cmd, the serial port was assigned to /dev/ttyS2. So I used UART2 GPIO pins (GP7C7 for TX, GP7C6 for RX) to interact. (snip) if test "${console}" = "serial" || test "${console}" = "both"; then setenv consoleargs "console=ttyS2,115200n8 ${consoleargs}"; fi (snip) The barudrate is 115200. Of course, I re-checked my connection between USB-UART serial cable and UART2 GP
  3. Putting the .ignore_changes did work fine. The original title was a little bit wrong. What I wanted to do is to build a v20.05 image and to get its kernel source code (the actual version is 5.4.57 rather than 5.7.14). The correct way to do it is Clone the master (https://github.com/armbian/build.git) Run vagrant if necessary (cd ./config/templates; vagrant up; vagrant ssh; cd armbian) Run sudo git checkout origin/v20.05 Run sudo touch .ignore_changes Run ./compile.sh BOARD=tinkerboard RELEASE=buster BRANCH=current BUILD_DESKTOP=no KERNEL_ONLY=no KERNEL_C
  4. I found it in the document after posting this and now I've being trying it, thanks. I will try this option as well later on.
  5. I'm trying to build a kernel driver for 5.7.14 for my custom image but couldn't find a linux-source package for the kernel version at https://mirrors.netix.net/armbian/apt/pool/main/l/ I tried to use armbian-config but it didn't show it, either (5.4.44 was listed instead). Where can I get 5.7.14 source code? I checked out Armbian Build v20.05( https://github.com/armbian/build/releases/tag/v20.05 )and created an image with the following options: BOARD=tinkerboard RELEASE=buster BRANCH=current BUILD_DESKTOP=no KERNEL_ONLY=no KERNEL_CONFIGURE=no INSTALL_HEADERS=yes BUILD_MINIMAL=y
  6. I'm trying to build 4.19 kernel modules for Tinkerboard with Armbian's build script (https://github.com/armbian/build). But when I chose the board 'Tinkerboard' from the Armbian building script CUI menu, the output ko files were all built for 4.4. How can I create 4.19 ko files for Tinkerboard? I tried to put userpatches/lib.config in order to overwrite KERNELBRANCH with tag:v4.19.y but not luck. The error was shown below: [ o.k. ] Using config file [ /vagrant/userpatches/config-example.conf ] [ o.k. ] Preparing [ host ] [ o.k. ] Build host OS release [ bionic ] [ o.k. ]
