The provided "galcore.ko" is built using Fenix 0.8.1 based on Kernel 4.9.0, so it might not be compatible with 5.5.0 kernel.

Linux Khadas 4.9.206 #13 SMP PREEMPT Tue Dec 31 00:37:47 CST 2019 aarch64 aarch64 aarch64 GNU/Linux

It would be good to get the exact error messages in dmesg on failed insmod

Maybe I have to built it myself.

[thezha]

Have you tried --force option with insmod?

[wuqiangch]

@thezha I have try it,but failed.

@wuqiangch The fastest way is to switch to 4.9.0 system image until we can supply a prebuilt-sdk for 5.5.0. You may also have trouble building it yourself since the galcore used by TIM-VX might not match the opensource version you have. Thanks!

[wuqiangch]

@thezha Ok.Thanks!

@wuqiangch your system need to switch to VIM3_V0.9-20200530(i guess your board is vim3).
download last fireware and flash your vim3, than do apt full-update.
KHADAS VIM3 fireware download page: https://docs.khadas.com/firmware/Vim3Firmware.html
update your board:

sudo apt update
sudo apt full-upgrade

you can switch to other apt source, such as Ali source(https://developer.aliyun.com/mirror/).
sample is below:

deb-src https://mirrors.aliyun.com/ubuntu-ports/ focal main restricted universe multiverse

deb https://mirrors.aliyun.com/ubuntu-ports/ focal-security main restricted universe multiverse
deb-src https://mirrors.aliyun.com/ubuntu-ports/ focal-security main restricted universe multiverse

deb https://mirrors.aliyun.com/ubuntu-ports/ focal-updates main restricted universe multiverse
deb-src https://mirrors.aliyun.com/ubuntu-ports/ focal-updates main restricted universe multiverse

deb https://mirrors.aliyun.com/ubuntu-ports/ focal-proposed main restricted universe multiverse
deb-src https://mirrors.aliyun.com/ubuntu-ports/ focal-proposed main restricted universe multiverse

deb https://mirrors.aliyun.com/ubuntu-ports/ focal-backports main restricted universe multiverse
