  1. # PROBLEM: Recent bananapi m1 images (and other A20 boards?) have no kernel headers, and armbian-config is not working so no hardware support. # SOLUTION: Armbian_23.02.2_Bananapi_jammy_current_5.15.93.img.xz Take this image and install the headers manually - or update to recent ones from here (not all work). NOTE: Armbian_23.02.2_Bananapi_jammy_current_5.15.93_minimal.img.xz While is the same build, cannot unfreeze kernel changes in armbian-config gui Flash SD and drop the 3 kernel packages in /root/ After first boot run $ apt upgrade && apt upgrade --fix-missing Unfreeze kernel with $ armbian-config -> system -> unfreeze (should accept) Install kernel packages: $ dpkg -i <package-dtb.deb> <package-image.deb> <package-header.deb> reboot & freeze kernel again compare build scripts current vs minimal - and merge upstream? I am noob Please show the way. Files pack: https://www.dropbox.com/scl/fo/0bdengzqkn5x798ddxvp7/h?rlkey=i6kilnhhr6xzxgkmipfqy19pr&dl=0 credits: Note to self: I should learn how to compile and build images.
  2. i have a tablet on Allwinner A20, I burned Armbian_23.5.0-trunk.134_Lime2_bookworm_edge_6.2.12_xfce_desktop.img.xz into sdcard, it looks like everything is okay, but the tablet work only via HDMI, how to enable the tablet display ?
  3. I'm having trouble connecting my Android phone when it doesn't automatically connect and recognize. Is there a way to fix it or is there any documentation? Since it has so many different versions, I tried it and it still failed automatically. Sincerely thank you.
  4. I am making some testing over A20-SOM from Olimex. I have a signal connected to NMI_N pin and with a legacy distribution, with power_start=0 on FEX, I am able to poweroff the board from command line (while the board is still powered) and then poweron/weakup the board raising up the signal on NMI_N. However, I need to do this on an armbian mainline distribution. I poweroff the board from command line (but keep the board powered), the PWR_LED keeps turn on and the board should wakeup when I turn on the signal on NMI_N and it does on my legacy distribution but not in armbian. Has anyone any clue, advice/tip to make this work in armbian? I really don't know where to start. if this helps, here are the docs of A20-SOM and AXP209: http://dl.linux-sunxi.org/AXP/AXP209_Datasheet_v1.0en.pdf https://www.olimex.com/Products/SOM/A20/A20-SOM/resources/A20-SOM-user-manual.pdf Many thanks for considering my request!
  5. Hello, I need to use an IRQ interruption with a button. I mean, I push a button, and then a code is executed. Some information: The PIN is PH19, EINT19. and the board A20 SOM. Armbian SO, kernel 4.13 Firstly i configure the digital pin and IRQ from user space: echo 243 > /sys/class/gpio/export echo "in" > /sys/class/gpio/gpio243/direction echo "falling" > /sys/class/gpio/gpio243/edge Now, when I push the button, I can monitoring the IRQ and the counter related to cat /proc/interrupts But now, how can I run a program when the interruption event happens ? I have seen this useful link http://linux-sunxi.org/External_interrupts How can i use it? I think there is very few information about this issue. I executed a bash script with while true , and polling the digital pin, but the disadvantage is that it consumes a lot of cpu. I hope you can help me. Thank you very much in advance Regards
