Missing option module in Axon kernel

LukasHlavac

Hi all,

could anyone give me advice about easiest way how to add option module (https://git.unipi.technology/UniPi/axon-linux/blob/axon/drivers/usb/serial/option.c) to kernel on my Axon? Is it necessary to compile whole kernel?

Thank you for your anwer.

If there are some missing modules, you need to compile it.
On Axon (or generaly any arm64 platform) do:

apt install build-essential git 
git clone https://git.unipi.technology/UniPi/axon-linux.git
make unipi-axon_defconfig

Now you can change kernel configuration to desired state

make menuconfig

Compile new modules

make modules

You can compile on amd64 platform using CROSS_COMPILE

make unipi-axon_defconfig CROSS_COMPILE=aarch64-linux-gnu- ARCH=arm64
make menuconfig CROSS_COMPILE=aarch64-linux-gnu- ARCH=arm64
make modules CROSS_COMPILE=aarch64-linux-gnu- ARCH=arm64
