VAR-SOM-MX7 Yocto Jethro Customizing kernel and U-Boot
From Variscite Wiki
VAR-SOM-MX7 - 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-mx6ul-mx7/blob/imx_4.1.15_ga-var01/recipes-kernel/linux/linux-variscite_4.1.15.bb
SRCBRANCH_mx6ul = "imx-rel_imx_4.1.15_1.1.0_ga-var02"
SRCBRANCH_mx7 = "imx-rel_imx_4.1.15_1.2.0_ga-var01"
SRCREV = "${AUTOREV}"
KERNEL_SRC ?= "git://github.com/varigit/linux-2.6-imx.git;protocol=git"
with your own. For example:
SRCBRANCH_mx6ul = "imx-rel_imx_4.1.15_1.1.0_ga-var02"
SRCBRANCH_mx7 = "imx-rel_imx_4.1.15_1.2.0_ga-var01"
SRCREV = "${AUTOREV}"
KERNEL_SRC ?= "git://github.com/customer/linux-2.6-imx.git;protocol=git"
Also replace:
https://github.com/varigit/meta-variscite-mx6/blob/imx-4.1.15-1.2.0_ga-var01/recipes-bsp/u-boot/u-boot-variscite_2015.04.bb
SRCREV = "${AUTOREV}"
SRCBRANCH = "imx_v2015.04_4.1.15_1.1.0_ga_var01"
SRC_URI = "git://github.com/varigit/uboot-imx.git;protocol=git;branch=${SRCBRANCH}"
to replace Variscite's U-Boot with your own.
