How to Build Linux Kernel for Trizeps VIII & Trizeps VIII Mini
This is only a quick-reference on how to build a Linux Kernel including Seco specific changes.
For details please view the Linux and NXP i.MX8M documentation.
Get the source code of linux-imx from the git repository:
$ git clone https://git.seco.com/seco-ne/kernel/linux-imx-kuk.git -b kuk_imx_4.14.98_2.0.0_gaSetup Cross-Build environment (View Software-Development-Kit on how to install.):
$ . /opt/fsl-imx-fb/4.14-sumo/environment-setup-aarch64-poky-linuxBuild Linux-Kernel from source code:
~/linux-imx$ make ARCH=arm64 defconfig
~/linux-imx$ LDFLAGS=
~/linux-imx$ makeThis will generate linux kernel ('Image') and device-tree binary ('*.dtb') files.
After you generated the kernel, you might want to build the kernel-modules:
Note: When the kernel boots it loads kernel-modules from the root-filesystem at '/lib/modules/<kernel-build-number>' (i.e. /lib/modules/4.14.78-imx_4.14.78_1.0.0_ga+g66620c3). The kernel-build-number is derived from git. To prevent to update the kernel-module-directory during development, it can be useful to set the kernel-build-number to a fixed value by setting 'CONFIG_LOCALVERSION' in ~/linux-imx/kernel/configs/kuk-trizeps8.config. This is not recommended for production-builds!
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:
This will configure the USB-OTG port to emulate a USB-Mass-Storage device.
Example:
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.
Copy the kernel-modules-directory to the second partition contains the root-filesystem.
Hints on using the Kernel
Device Tree
The Linux-kernel will use a Device-Tree-Binary file (.dtb) to determine how the Trizeps 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 |
|---|---|---|
kuk-trizeps8 | Basic Device-Tree for the Trizeps VIII module itself, which is included by all other Device-Tree baseboard files | |
kuk-trizeps8-pconxs-edt7 | Trizeps VIII in pConXS with EDT 7inch display | |
kuk-trizeps8-pconxs-hdmi | Trizeps VIII in pConXS using HDMI output | |
kuk-trizeps8-ipant7 | Trizeps VIII in i-PAN T7 panel | |
kuk-trizeps8-ipant10 | Trizeps VIII in i-PAN T10 panel | |
kuk-trizeps8mini | Basic Device-Tree for the Trizeps VIII Mini module itself, which is included by all other Device-Tree baseboard files | |
kuk-trizeps8mini-pconxs-edt7 | Trizeps VIII Mini in pConXS with capacitive touch EDT 7inch display | |
kuk-trizeps8mini-pconxs-edt7-pcie | Trizeps VIII Mini in pConXS with capacitive touch EDT 7inch display and PCIE-slot | |
kuk-trizeps8mini-pconxs-edt7res | Trizeps VIII Mini in pConXS with resistive touch EDT 7inch display | |
kuk-trizeps8mini-pconxs-edt7res-pcie | Trizeps VIII Mini in pConXS with resistive touch EDT 7inch display and PCIE-slot | |
kuk-trizeps8mini-ipant7 | Trizeps VIII Mini in i-PAN T7 panel | |
kuk-trizeps8mini-ipant7-v2 | Trizeps VIII Mini in i-PAN T7-V2 panel | |

When you open the u-boot command prompt and output the environment, you can determine which device-tree is used:
To change this you can call:
'env save' will store this setting for subsequent boots.
Root-Filesystem
To have a full running Linux-system you will need:
Bootloader ( U-Boot, Trizeps VIII ), 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:
