Introduction[edit | edit source]
As explained here, BELK/BXELK structure is not based on PetaLinux build system. Instead, BELK/BXELK make use of a standardized Yocto-based build system to build all the software components—U-Boot, Linux kernel, and root filesystem—that run on the Processing System (PS). This choice is more flexible and more modularized but it requires a little bit more knowledge of embedded Linux systems.
That being said, there are cases in which it can be convenient to build such components with PetaLinux build system, however. This technical note shows how to build the Linux kernel image released with BELK/BXELK with PetaLinux build system.
The procedure was tested with the following configuration.
| Component | Version |
|---|---|
| PetaLinux | 2017.2 |
| BELK/BXELK | 4.0.0 |
Building the Linux kernel[edit | edit source]
petalinux-create --type project --template zynq --name bora1
petalinux-config --get-hw-description=/home/dvdk/devel/bora/bora-minimal/bora-minimal.sdk/
kernel directory
DTS include directory
Add in build/conf/plnxtool.conf LINUX_VERSION_EXTENSION = "-belk-4.0.0"
