  1. Thank you @Gavinb for your suggestion - you were right! After pulling out the board from the enclosure I realized, on end of the the flat-ribbon LCD was connected upside down (the part on the extension PCB). But this just opened a new can of worms After plugging everything together I inserted the DC barrel jack (original 5V 3A power supply) and then the LED goes on only for 1-2 seconds and then goes off. The serial output always goes only so far: U-Boot SPL 2019.04-armbian (Feb 02 2020 - 16:05:24 +0100) DRAM: 2048 MiB Trying to boot from MMC2 NOTICE: BL3-1: Running on A64/H64 (1689) in SRAM A2 (@0x44000) NOTICE: Configuring SPC Controller NOTICE: BL3-1: v1.0(debug):c9f55c0 NOTICE: BL3-1: Built : 16:05:19, Feb 2 2020 NOTICE: DT: sun50i-a64-sopine-baseboard INFO: Configuring AXP PMIC NOTICE: PMIC: fixing DRAM voltage from 1.24 With the LCD ribbon cable unplugged the board boots normally. I am trying now to find some (Android) image to see whether it is not a LCD issue.
  2. I had also issues when flashing an Armbian image to emmc module using the USB-adapter. I almost suggested my Pine A64-LTS or the emmc was not working properly. The solution was to flash an image to SD-card, boot from SD with module connected to the board and use the nand-sata-install script which copies a bootable copy of the system to the emmc module. Afterwards I powered-off the board, removed the SD card and the board was booting from the module You should also verify if the emmc module is recognized - there should be emmcblk0 and emmcblk1 device in /dev - one for the SD card and one for the emmc module.
  3. So booting from SD card and doing nand-sata-install solved my problem with the eMMC My Pine A64-LTS runs from an eMMC module now But still no luck regarding the LCD. I did dmesg | grep dsi and here is the output [ 8.577279] sun4i-drm display-engine: failed to bind 1ca0000.dsi (ops 0xffff000010b79400): -517 [ 8.592781] sun6i-mipi-dsi 1ca0000.dsi: Couldn't register our component [ 8.609448] sun4i-drm display-engine: failed to bind 1ca0000.dsi (ops 0xffff000010b79400): -517 [ 8.610876] sun6i-mipi-dsi 1ca0000.dsi: Couldn't register our component [ 8.641097] sun4i-drm display-engine: failed to bind 1ca0000.dsi (ops 0xffff000010b79400): -517 [ 8.645801] sun6i-mipi-dsi 1ca0000.dsi: Couldn't register our component [ 8.660508] sun4i-drm display-engine: failed to bind 1ca0000.dsi (ops 0xffff000010b79400): -517 [ 8.661052] sun6i-mipi-dsi 1ca0000.dsi: Couldn't register our component [ 8.676834] sun4i-drm display-engine: failed to bind 1ca0000.dsi (ops 0xffff000010b79400): -517 [ 8.699172] sun6i-mipi-dsi 1ca0000.dsi: Couldn't register our component [ 8.738486] sun6i-mipi-dsi 1ca0000.dsi: Attached device fy07024di26a30d [ 8.743141] sun4i-drm display-engine: bound 1ca0000.dsi (ops 0xffff000010b79400) I of course tried to boot without HDMI - no luck so far. I was also forced to comment-out the gt9xxf_ts entry in /etc/modules because there was an error message during the boot stating, that the module is not available
  4. @Gavinb Many thanks for your reply. I actually created an Image without the desktop environment since I am going to create a minimal kiosk-browser environment for OpenHab. I already created new user since the board is connected to LCD screen over HDMI. Can this be the cause ? I actually never tried to boot with unplugged HDMI Also I added the pine64_lcd=on to armbianEnv.txt, and gt9xxf_ts to /etc/modules
  5. @Learnincurve You were right! I was actually able to build an image over the last weekend, since @Gavinb was so kind and responded to my personal message. I was able to boot the image on my Pine A64 LTS using a SD card, still not able to see anything on the display. Currently I am trying also to figure out how to boot from eMMC. I hope I will find time this evening to attach a serial cable and look on the booting process. Kernel 5.6-rc1 was released two days ago, I wonder if there is possibility to try it using the armbian build-tool
  6. I am sorry for posting in this older thread, but it is actually the first relevant google search result. I am trying to create an flashable image for my A64-LTS board with LCD/DSI support. more to it here. The script always fails with the Image build error : Unable to locate package armbian-firmware error. My setup is: current Virtualbox with Ubuntu 18.04. minimal image tweaked build script from https://github.com/GavinBa/build.git containing all the necessary fixes for working LCD and touch What I do: ./compile.sh LIB_TAG=v9-a64-dsi I select following options: Full OS image for flashing, Don't change the kernel configuration, Target board: pine64so, Kernel next (Mainline), Target OS: stretch Debian 9, Image with console interface I already tried ./compile.sh LIB_TAG=v9-a64-dsi EXTERNAL=no but that didn't help either. I am really stuck now, could someone help me with this ?
  7. I tried today several times to compile an image, but the script always ends with: Image build error : Unable to locate package armbian-firmware My setup: current Virtualbox with Ubuntu 18.04. minimal image cloned the https://github.com/GavinBa/build.git repository ./compile.sh LIB_TAG=v9-a64-dsi then selected: Full OS image for flashing, Don't change the kernel configuration, Target board: pine64so, Kernel next (Mainline), Target OS: stretch Debian 9, Image with console interface I tried to google for the above error message, but not lock so far
  8. Great! Thank you so much fr your effort! I would love to try. I assume I can try the build script from https://github.com/GavinBa/build/tree/v9-a64-dsi and should be using the https://github.com/amarula/linux-amarula/tree/v9-a64-dsi kernel ? How do I tell the script to use the kernel ? I tried to find the answer in https://docs.armbian.com/Developer-Guide_Build-Options/ but no luck
  9. @Gavinb Hello Gavin, I'd like to ask about your progress with the build-script ? Could you resolve your issues with the i2c/touch ? I was tracking the progress in you repository, the latest changes are about 2 weeks old.
  10. I am also super excited about this news. I have on original Pine A64 board from the kickstarter campaign and one Pine A64 (+) LTS, I hope I would be able to get the LCD running on both of them. Is there some output from i2cdetect ? I2C bus locked can be sometimes caused by too high bitrate.
  11. Hello, any updates on this ? @Gavinb How was your experience with the v9-a64-dsi kernel ?
