Yocto Customizing the Linux kernel
From Variscite Wiki
- Customizing the Linux kernel and U-Boot
Once completed developing your own kernel and U-Boot, create your own github account and upload your proprietary kernel and U-Boot to a new repository.
Replace Variscite's Kernel and U-Boot yocto links, to point to your newly created github branches. i.e. replace kernel link:
https://github.com/varigit/meta-variscite-fslc/blob/morty/recipes-kernel/linux/linux-variscite_4.1.15.bb
SRCBRANCH = "{{#var:KERNEL_BRANCH}}"
SRCREV = "fixed commit id"
KERNEL_SRC ?= "git://github.com/varigit/linux-2.6-imx.git;protocol=git"
with your own. For example:
SRCBRANCH = "{{#var:KERNEL_BRANCH}}"
SRCREV = "${AUTOREV}"
KERNEL_SRC ?= "git://github.com/customer/linux-2.6-imx.git;protocol=git"
Also replace:
https://github.com/varigit/meta-variscite-fslc/blob/morty/recipes-bsp/u-boot/u-boot-variscite.bb
SRCREV = "fixed commit id"
SRCBRANCH = "{{#var:U-BOOT_BRANCH}}"
SRC_URI = "git://github.com/varigit/uboot-imx.git;protocol=git;branch=${SRCBRANCH}"
to replace Variscite's U-Boot with your own.
We recommend to use "${AUTOREV}" during development to get the latest Kernel and U-boot when you build Yocto
