Yocto bsp kernel

Skill Higangssh/yocto-agent-skills/skills/yocto-bsp-kernel

Review and debug Yocto BSP, MACHINE configuration, kernel provider selection, kernel recipes, kernel config fragments, defconfig, devicetree, U-Boot, FIT images, deploy artifacts, and kernel module installation. Use for machine/BSP/kernel/devicetree/bootloader issues or when kernel artifacts are missing from deploy output.From its SKILL.md

Yocto BSP Kernel

Use this skill for machine, BSP, kernel, devicetree, and bootloader work. Verify the selected machine, enabled BSP layers, kernel provider, and deploy artifacts before changing recipes.

Evidence

Ask for or inspect:

MACHINE
conf/machine/*.conf
enabled BSP layers
PREFERRED_PROVIDER_virtual/kernel
kernel recipe and bbappends
KERNEL_DEVICETREE
defconfig or config fragments
U-Boot variables
tmp/deploy/images/<machine>/

Useful commands:

bitbake-layers show-layers
bitbake-layers show-recipes virtual/kernel
bitbake-layers show-appends | rg 'linux|kernel|u-boot'
bitbake -e virtual/kernel | rg '^(MACHINE|PREFERRED_PROVIDER|KERNEL|UBOOT|SRC_URI|S)='
bitbake -c kernel_configme virtual/kernel
bitbake -c kernel_configcheck virtual/kernel
bitbake -c menuconfig virtual/kernel
bitbake -c diffconfig virtual/kernel
bitbake -c savedefconfig virtual/kernel

Review Rules

Machine config should express hardware policy; distro config should express product policy.
Select kernel through PREFERRED_PROVIDER_virtual/kernel in machine or distro policy.
Keep devicetree names aligned with kernel source and machine config.
Use kernel config fragments or defconfig intentionally; validate with kernel config tasks.
Verify deploy artifacts before debugging bootloader or flashing.
Check vendor BSP branch compatibility before modernizing syntax.

References

Output

Answer with:

selected machine and kernel provider
BSP/layer compatibility risk
kernel/devicetree/bootloader metadata issue
command to validate config or deploy artifacts
minimal metadata change
