Linux 5.4, Myon II

Linux 5.4 based on NXP 5.4.24_2.1.0 ssh://

The Myon II is software-compatible to the Trizeps VIII Mini module.
Because Trizeps VIII, Trizeps VIII Mini and Myon II share the same kernel source code, you may a look at Linux 5.4, Trizeps VIII (-/Mini/Nano) for instructions on how to build and deploy an image. The only difference is the Device-Tree-Binary (.dtb) file passed to the kernel on boot.

Previous Versions

Branch/Tag Comment
kuk_5.4 Based on kuk_android-10.0.0_2.3.0. Intended to be used for all 5.4 Linux-Kernel (Yocto,Android,Debian,…)
kuk_android-10.0.0_2.3.0 Merged kuk_imx_5.4.24_2.1.0 with NXP Android 10 patches
kuk_imx_5.4.24_2.1.0 Derived from imx_5.4.24_2.1.0 with Keith & Koep patches

How to Build Linux Kernel for Myon II

This is only a quick-reference on how to build a Linux Kernel including Keith & Koep specific changes.
For details please view the Linux and NXP i.MX8M documentation.

Get the source code of linux-imx from git repository:

$ mkdir linux-imx
$ git clone -b kuk_5.4

Setup Cross-Build environment (View Software-Development-Kit on how to install.):

$ . /opt/fsl-imx-fb/5.4-zeus/environment-setup-aarch64-poky-linux
$ export ARCH=arm64

Build Linux-Kernel from source code:

~/linux-imx$ make imx_v8_defconfig
~/linux-imx$ make

This will generate linux kernel ('Image') and device-tree binary ('*.dtb') files.


After you generated the kernel, you might want to build the kernel-modules:

~/linux-imx$ make modules
~/linux-imx$ make modules_install INSTALL_MOD_PATH=~/linux-imx-modules

Note: When the kernel boots it loads kernel-modules from the root-filesystem at '/lib/modules/<kernel-build-number>' (i.e. /lib/modules/5.4.24).

Update Kernel

Updating the kernel involves to copy 'Image' and the kernel-module directory to the device.
If the kernel-build-version did not change, copy of the kernel-module directory can be omitted.

Update using USB and bootloader

Enter the bootloader command console and run:

u-boot=> ums 0 mmc 0

This will configure the USB-OTG port to emulate a USB-Mass-Storage device.

$ lsblk
sda      8:0    0   240G  0 disk 
├─sda1   8:1    0   232G  0 part /
└─sda2   8:2    0     8G  0 part 
sde      8:64   1   3,8G  0 disk 
└─sde1   8:65   1   3,8G  0 part /media/imx6/9016-4EF8
sdf      8:80   1   7,1G  0 disk 
├─sdf1   8:81   1   500M  0 part /media/imx6/00BA-BF8A
└─sdf2   8:82   1   6,6G  0 part /media/imx6/fd195515-0a44-4a7e-9387-bec6087f37ac
sr0     11:0    1  1024M  0 rom  

After calling 'ums 0 mmc 0' a new device 'sdf' appears in the list of mounted devices.

Copy the kernel-'Image' and device-tree binary files to the first partition.

$ cp ~/linux-imx/arch/arm64/boot/Image /media/imx6/00BA-BF8A/Image
$ cp ~/linux-imx/arch/arm64/boot/dts/keithkoep/*.dtb /media/imx6/00BA-BF8A/

Copy the kernel-modules-directory to the second partition, which contains the root-filesystem.

cp -r ~/linux-imx-modules/* /media/imx6/fd195515-0a44-4a7e-9387-bec6087f37ac

Hints on using the Kernel

Device Tree

The Linux-kernel will use a Device-Tree-Binary file (.dtb) to determine how the Myon module is used in a system (i.e. which drivers to load). The device-tree files can be found at:


When building the Linux-kernel .dts source-files are converted to .dtb binary files.

DeviceTree (dtb) Module Description

When you open the u-boot command prompt and output the environment, you can determine which device-tree is used:

u-boot=> env print -a

To change this you can call:

u-boot=> env set fdt_file kuk-myon2-ipanm7.dtb
u-boot=> env save

'env save' will store this setting for subsequent boots.


To have a full running Linux-system you will need:

  • Bootloader ( U-Boot, Myon II ), which loads the Device-Tree and Linux-Kernel.
  • Linux Kernel
  • Root-Filesystem, which contains applications, configuration files etc.

There are different approaches on how to create a root-filesystem.
Basicly its a linux-distribution like Debian, where the system is put together by packages or like Yocto, where recipes define what needs to be built and put inside the file-system:
