I want to change the kernel config.
I ran the following to create fragment.cfg.
$ bitbake virtual/kernel -c menuconfig
$ bitbake virtual/kernel -c diffconfig
Please tell me how to make a recipe to reflect this.
Or provide a sample recipe.

Dear @C.T, welcome to the Toradex Community.
We have information here on how to modify the kernel configuration in Yocto:
Let us know if you need further help.
Kind regards,
Alvaro.
I created the following configuration.
.
├── COPYING.MIT
├── README
├── conf
│ └── layer.conf
└── recipes-kernel
└── linux
├── linux-toradex
│ └── fragment.cfg
└── linux-toradex_%.bbappend
The bbappend file is described as follows.
FILESEXTRAPATHS_prepend := “${THISDIR}/${PN}:”
SRC_URI_append += "\
file://fragment.cfg
"
do_configure_append() {
cat …/*cfg >> ${B}/.config
}
bitbake
bitbake -b meta-customer/recipes-kernel/linux/linux-toradex_%.bbappend

Question
・Why do you get such an error?
・Is the bbapend file correct?
Hi @C.T, thanks for the details.
You cannot build a bbappend, only a bb file.
To build the kernel, you should use the following:
bitbake virtual/kernel
Please note the error message mentions that this is not a Bitbake file:
raise ParseError("not a BitBake file", fn)
bb.parse.ParseError: ParseError in /home/****/work/yocto/test/layers/meta-customer/recipes-kernel/linux/linux-toradex_%.bbappend: not a BitBake file
The bbappend looks good by itself
I executed as below.
bitbake virtual/kernel
Can you confirm this change?(no Actual machine)
I understand that you added the content of fragment.cfg: What are the changes there? I checked the question but didn’t see it here.
In any case, testing would take a long time since we would have to recompile it here with your changes changes but you can do several things to test this without the machine:
Let us know how this goes and if it doesn’t show the changes, please post the changes and we will check.
Kind regards,
Alvaro.
test fragment.cfg (change CONFIG_COUNTER=y)
CONFIG_LOCALVERSION="-5.1.0-devel"
CONFIG_LOCALVERSION_AUTO=y
CONFIG_COUNTER=y
# CONFIG_FTM_QUADDEC is not set
Revert the changes for confirmation.
bitbake -c menuconfig virtual/kernel
CONFIG_COUNTER=n
Bitbake
bitbake virtual/kernel
Check
bitbake -c menuconfig virtual/kernel
But,CONFIG_COUNTER=n
meta-toradex-demos includes fstab.
Is it related?
Sorry for the delay. Could be that the prepend is not done correctly
Please try the supported method of creating a patch file like described here:
For this,
tmp/work-shared/colibri-imx6ull/kernel-source/
in another folder.defconfig/kernel on arch/arm/configs/colibri-imx6ull_defconfig
git diff HEAD > mypatch.patch
