Buildroot-YuzukiSBC Built-in Script
For Environment
wsl_path
If you are using the WSL environment, please run this command to clear the WSL environment variables before compiling, otherwise the following error will occur.
Your PATH contains spaces, TABs, and/or newline (\n) characters.
This doesn't work. Fix you PATH.
support/dependencies/dependencies.mk:27: recipe for target 'dependencies' failed
make: *** [dependencies] Error 1
For Build
lunch
Lunch 🚀 to buildroot.
rebuild_kernel = mkernel = rkernel
Delete the generated dtb and rebuild the kernel
rebuild_uboot = muboot = ruboot
Rebuild the U-Boot
sync_kernel
Modify the kernel-related patch or need to restore the original kernel, sync to original
sync_uboot
Modify the uboot-related patch or need to restore the original uboot, sync to original
sync_update
Sometimes when you upgrade Buildroot YuzukiSBC, you will find that the compilation does not pass, please use this command to delete the old files
Appendix
board file trees and file path definition
Buildroot-YuzukiSBC uses a custom directory structure, and the following descriptions need to be met when submitting code.
- Do not use custom kernel, uboot and other repo, use patch to modify.
- All configuration files and device trees are external and handed over to buildroot.
- Common files, drivers, packaging scripts, etc. are placed in the
xxx-genericfolder.

For Allwinner SUN20IW1P1 Platform
OpenSBI-D1
For the sun20iw1p1(D1-H, D1s) platform, we introduced its stable version of OpenSBI as Supervisor Binary Interface. Which is not compatible with the upstream mainline OpenSBI.
post-build.sh
Since the main line currently lacks support for chips and has fewer drivers, the BSP kernel and U-boot are used here. The compilation method and startup method are quite different from the mainline. This script is used here as the connection.
Since Buildroot does not provide dedicated ARGS for Post Script, it is shared with BR2_ROOTFS_POST_SCRIPT_ARGS, so it needs to be written together with the packaging script here.
Usage
post-build.sh -c xxxx.cfg <platform> <target dtb>
^for pack image ^for post-build.sh
In config
BR2_ROOTFS_POST_SCRIPT_ARGS="-c board/awol/nezha-d1s/script/genimage.cfg sun20i-d1s sun20i-d1s-nezha-linux.dtb"
^for pack image ^target platform name ^device tree
XFEL Driver install
First, open zadig under the XFEL driver folder and select List All Devices
Then select Allwinner USB Device VID_1f3a_PID_efe8, and replace the driver with WinUSB
