kernel patch specified via SRC_URI never gets applied. I followed the instructions for adding and building a linux-windriver-custom recipe : https://knowledge.windriver.com/en-us/000_Products/000/010/000/030/000_Wind_River_Linux_Kernel_and_BSP_Developer's_Guide%2C_7.0/020/020 and i added a kernel-specific configuration and patch via SRC_URI variable but the patch never get applied to the kernel.
1. follow the documented instructions to build using a custom kernel recipe:
--- https://knowledge.windriver.com/en-us/000_Products/000/010/000/030/000_Wind_River_Linux_Kernel_and_BSP_Developer's_Guide%2C_7.0/020/020
Building the Kernel Using the Custom Kernel Recipe
---
Basically 4 files are created/modified. I attached them :
they are
bblayer.conf
+
wrl-7/workspace_IA/pp_custom-linux$ tree layers/local/recipes-kernel/linux/
layers/local/recipes-kernel/linux/
+-- linux-windriver-custom
¦ +-- 0001-Break-the-build.patch
¦ +-- defconfig
+-- linux-windriver-custom.bbappend
Hereafter my config line :
---
configure --enable-jobs=4 --enable-parallel-pkgbuilds=4 --enable-board=qemux86-64 --enable-build=production --enable-kernel=standard --enable-rootfs=glibc-core --enable-unsupported-config=yes --enable-reconfig --enable-internet-download=yes --with-layer=wr-kernel/kernel-dev --with-template=feature/custom-kernel --with-rcpl-version=0020
---
Once the project is configure and the linux-windriver-custom recipe in place (defconfig + .patch + modification in bblayers.conf)
make linux-windriver-custom
==> the patch is never applied although i verified SRC_URI is correctly set :
---
