I have hard time running NPU demos on VIM3.
Which Ubuntu version to use?
I followed official docs and checked “NPU Demo and source code” post.
Many of the links point to 2019 firmware (I started with it but had problems)
Emmc flashed VIM3_Ubuntu-gnome-focal_Linux-4.9_arm64_EMMC_V0.9-20200530.img from the official repo.
First I tried to use prebuilt binaries with demos - or to build myself.
Using latest 6.4.3 for SDK
2 Problems with inceptionv3
- I am getting error about missing libOpenVX.so.1.2. There is /lib/libOpenVX.so - I tried to copy as so.1.2. Getting “segmentation error”.
I see lsmod galcore (not sure what it is?) - but that means I have NPU…
- I got similar errors with demo_detect_picture v3
- I built from source some of the demos - also run time errors.
apt upgrade was as disaster - I had to reflash the image.
Please, confirm if you have recent success with newer builds.
Should I go back to 2019? or build ubuntu with fenix?

I like the VIM3 board - but NPU seems very rough…
