Download source

To obtain the am335x-linux-4.4 sources you must clone them as below:

git clone https://github.com/Moxa-Linux/am335x-linux-4.4

📘 Refer to https://github.com/Moxa-Linux/linux-4.4.git for newer kernel source and building flow.

Dependencies

To build am335x-linux-4.4, we provide moxa-dockerfiles to create build environment.

Building

Create docker container

To create a docker container execute the following commands from the directory which source in:

# sudo docker run -d -it -v ${PWD}:/workspace moxa-package-builder:1.0.0 bash
d103e6df5f719f9430056f9c23cf4e3e518d4a4f8b5b65e55889b90c258886c6

After execute commands, you will get a string like d103e6df5f719f9430056f9c23cf4e3e518d4a4f8b5b65e55889b90c258886c6 which called <container_id> and we will use it in next step.

Build kernel package

To build kernel package execute the following commands:

# docker start -ia <container_id>
# cd /workspace/am335x-linux-4.4
# apt-get build-dep -aarmhf .
# dpkg-buildpackage -us -uc -b -aarmhf

Once build process complete, you can find .deb files under /workspace directory.

Updating

After build the kernel packages, now you can update your device.

Below are instructions to update the kernel packages on UC-5100.

Upload the kernel packages to the device

To upload kernel package to the device execute the following commands:

# scp uc5100-kernel*.deb uc5100-modules*.deb [email protected]:/tmp

Install the kernel packages

To install kernel package to the device execute the following commands:

# cd /tmp
# dpkg -i *.deb
# sync

NOTE: Remember to reboot the device after install the kernel package!
