for the kernel modify
after build the kernel you will find the source code in the
/build/tmp/work-shared/plnx_arm/kernel-source
1. modify the code source in the
/build/tmp/work-shared/plnx_arm/kernel-source for example: drivers/w1/masters/w1-gpio.c
2. in the
/build/tmp/work-shared/plnx_arm/kernel-source do like this git add file1(like:drivers/w1/masters/w1-gpio.c) file2 ...
3. give a pacth tile
git commit -s -m 'your commit title'
4.create the pacth
git format-patch -1
#and then you will see the .pacth in you current directory.
5. copy this .pacth to the
/project-spec/meta-user/recipes-kernel/linux/linux-xlnx/ and add the linux-xlnx_%.bbappend file in the
/project-spec/meta-user/recipes-kernel/linux/ like:
SRC_URI_append = " file://xxxx.patch"FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:"
and then
and then petaliunx-build
and the new
/build/tmp/work-shared/plnx_arm/kernel-source code will add your patch.
and i think this will be helpful with you.
