  1. Wow that was quick! I didn't even have a chance to kick in....so what's next ?
  2. Good catch.... "git checkout v2015.04 -b tmp" should be "git checkout v2020.10 -b tmp"
  3. Thanks for that, Gediz, In looking at the Olimex forum post https://www.olimex.com/forum/index.php?topic=4463.0 regarding the A13, as well as http://linux-sunxi.org/LCD it would appear that the CONFIG_VIDEO_LCD_MODE is indeed part of the configuration for U-Boot, which requires U-boot to be custom built: git clone git://git.denx.de/u-boot.git cd u-boot/ git checkout v2015.04 -b tmp https://developer.arm.com/-/media/Files/downloads/gnu-a/9.2-2019.12/binrel/gcc-arm-9.2-2019.12-x86_64-aarch64-none-linux-gnu.tar.xz tar -xvf gcc-arm-9.2-2019.12-x86_64-aarch64-none-linux-gnu.tar.xz make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- a64-olinuxino_defconfig make menuconfig This allows the configuration of U-boot where the LCD can be properly enabled. I'm working on the next step, which is properly linking the compiler to build the U-boot image, as well as adding a user patch to armbian build tools to allow use of the custom U-boot binary. Stay tuned.
  4. One additional comment, I noticed according to the hardware notes in armbian docs that CONFIG_VIDEO_LCD_MODE must be enabled in kernel configuration. I just checked my kernel configuration and that option does not exist.
  5. LCD support does not appear to be working in the latest builds (stable kernel 5.8.6, development kernel 5.9.7) My understanding is that this has been an issue for a while with A64 boards, specifically the Pine64, but that it was working at one time. Here's what I've tried so far: -Followed instructions at https://docs.armbian.com/Hardware_Allwinner/ and added "setenv video-mode sunxi:480x272-24@60,monitor=lcd,hpd=1,edid=1" to boot.cmd and put "saveenv" at the end, re-compiled boot.scr -Did a modprobe of panel-olimex-lcd-olinuxino -Rebooted several times -Ensured that LCD jumper was closed and verified LCD was working with Olimex builds. Screen flickers at startup then stays white. Any thoughts?
  6. Levent Erenler thanks so much for sharing your discovery! I was able to get audio working on my Lime-A64 using the provided overlay.
  7. On the 20.08.2 Buster release (Kernel 5.8.6) the headphone jack is not currently working. HDMI audio seems to be supported. aplay -L returns only the HDMI audio interface. (sun50i-a64-hdmi) but is not showing the headphone interface (should additionally show sun50i-a64-audio as in other working builds) This is also the case with the current development build (Armbian_20.11.0-trunk.32_Lime-a64_buster_current_5.9.7) A look at the device tree shows “<stdout>: Warning (unit_address_vs_reg): Node /sound/simple-audio-card,dai-link@0 has a unit name, but no reg property” on the first line of the DTS of sun50i-a64-olinuxino, sun50i-a64-olinuxino-emmc, and sun50i-a64-olinuxino-2Ge8G device tree blobs. Not sure if this is a contributing factor. The snippet it seems to be complaining about: simple-audio-card,dai-link@0 { format = "i2s"; frame-master = <0x11>; bitclock-master = <0x11>; mclk-fs = <0x80>; I did some digging and found this patch from a few years ago: https://www.alsa-project.org/pipermail/alsa-devel/2018-October/141047.html The only major difference I see between the configuration added by the patch and my current device tree is that hex addresses are specified in place of pointer variables. (i.e. <0x12> vs <&dai> Going on the advice of several forum posts, I tried adding "overlays=analog-codec" to /boot/armbianEnv.txt to no avail. I suspect that analog audio needs to be enabled in kernel configuration.
  8. I am having this issue as well, and as far as I can tell, it has not been resolved yet. Can anyone confirm whether there is a newer release than the Olimex/Armbian release with kernel 5.2.5 where USB/eMMC are functional?
