August 5, 20224 yr Hi guys. I'm the maintainer for the Khadas VIM3. There are 2 small issue's with the Armbian images for VIM3, and also for VIM2. armbianmonitor -u http://ix.io/46L9 First off, the VIM3 has all its cores clocked to 1.5Ghz by default. I created a Jira for that a while ago. https://armbian.atlassian.net/browse/AR-1094 My simple fix is in /etc/default/cpufrequtils MAX_SPEED=15xxxxxxx → MAX_SPEED=2400000 But I have no idea how/where to adjust this so it is correct for all VIM3 images. Then for VIM2 and VIM3 (maybe VIM3L and VIM1 too) the HDMI audio isn't working as it should. https://armbian.atlassian.net/browse/AR-1095 I once was able to make it work. But I can't remember how. So the device is enabled at boot, but not directed to be used by pulseaudio. Thank you.

No one added the actual top speeds for the Vims apparently https://github.com/armbian/build/blob/master/config/sources/families/meson-g12a.conf#L5 is the override for the Meson G12A. G12B needs something similar in here: https://github.com/armbian/build/blob/master/config/sources/families/meson-g12b.conf
October 12, 20224 yr Hi @NicoD do you know if the NPU is working on the Vim3 using Armbian? I received my Vim3 yesterday so I still have a lot of reading to do.

I've not messed with the NPU, I should, but don't know a good use case. The things you'll have to read are probably this https://www.khadas.com/post/npu-toolkit-v6-4-0-10-for-vim3---vim3l-released And this https://forum.khadas.com/t/npu-demo-and-source-code/5938/13

Hi @NicoD I'm not sure that it's a right solution you've been looking for but it works with my VIM 3 Pro. See this topic on Khadas forum: Twister OS Armbian 2.01 on VIM3! GL Acceleration Fan and AUDIO - Full HOWTO and Working Image DL The details described in UPDATE 2: (In which audio works with correct ALSA configurations)
May 14, 20233 yr I notice my VIM3 Pro negotiated 12V power when running the originally supplied Android image or the Rescue image, but when using Armbian 23.02.2 Jammy with Linux 6.1.11-meson64 it stays at 5V.
