Now I see a big pool of classes that can be used. Eventually I found that why it doesn't work for me to add EXTRA_USER_PARAMS in image recipe is that I used this line: INHERIT += "extrausers" instead of this line: inherit extrausers to use the class extrausers. But at the beginning there was an error when using "inherit extrauser". Now it works fine. I couldn't figure out why. But anyway it works this way now.

Indeed, it is not relevant the value of the variable, but where it is assigned. It doesn't work to assign these values in image recipe, but works in local.conf. I am wondering what's the different in assigning the value in different locations. Maybe it is relevant to the building sequence. If it is assigned later, it is useless. Is there any rule to follow? Or it is just from experience? Another question I think of is how you guys source control local.conf. It looks it might be much different from project to project. Thanks!

Re: [yocto] EXTRA_USERS_PARAMS doesn't work to generate password for root and add new users
Thanks Mauro for your input. I referred two posts from Koan Software in my work. One is to use devtool to modify recipe and another one is to add system service to image. Very clearly explained. Thanks! Good point. I tried, but in my case it looks still not generating the password and also no new user added. And I am afraid that the $ symbol in the encrypted password string might prevent it from being applied. I tried to add \ before $ symbol. And it's also not working.

When checking the parameter, the result is: EXTRA_USERS_PARAMS=" usermod -P root root; useradd -P 2023 crane; " The image does requires a password for root, but doesn't generate anything in /etc/shadow and doesn't add new user in /etc/shadow as well.

Now the issue is with the patch itself. The patch is created by using "diff -ruN" is not working. The error is "no file to patch". I can understand this as the file compared to in the patch doesn't exist in the $(WORKDIR). I changed to use "git format-patch" in the $(WORKDIR) to generate the patch. But still not working. The error is "does not apply (enforce with -f)". And applying -f option got the same error. Where is the problem?

[yocto] How to add a few lines in config.txt in Yocto project for Raspberry Pi

Re: [yocto] the way to create patch for Linux kernel configuration
Finally found two ways to do this and worked in my case: 1. use bitbake -c diffconfig to create a fragment config and then add the fragment config to a .bbappend 2. add an out-of-tree defconfig in .bb The documentation says out-of-tree defconfig takes precedence. But in my case KBUILD_DEFCONFIG is used and the out-of-tree defconfig is dropped. No idea why.

[yocto] the way to create patch for Linux kernel configuration
Hello,
How do you create a patch for Linux kernel configuration in a customized layer
on top of an initial patch. It is a patch based on the original defconfig from
vendor meta layer? I tried different ways, but none of them work.
The initial .bbappend is like this. I would like to make further changes on top
of that.
SRCREV = "0086da6acd41600d47b87b05874f99704216426f"
FILESEXTRAPATHS:prepend := "${THISDIR}/${PN}:"
SRC_URI += "\
file://devtool-fragment.cfg \
"
1. use devtool to modify the current kernel configuration
After using devtool menuconfig to modify the kernel configuration, the .config
is updated.
But, here is a big BUT, after using devtool build to build kernel image, the
kernel image is still built using the defconfig originally from the vendor meta
layer meta-raspberrypi.
If using devtool update-recipe to create a patch any way, then do devtool reset
and use bitbake to build the kernel image, the result is the same (the kernel
image uses original defconfig).
2. use git format-patch to create a patch file and then add the patch file into
.bbappend.
Say, a patch 0001-update-kernel-config-to-enable-uart-console.patch is added
into files folder.
Then add one line in .bbappend file like this:
SRCREV = "0086da6acd41600d47b87b05874f99704216426f"
FILESEXTRAPATHS:prepend := "${THISDIR}/${PN}:"
SRC_URI += "\
file://devtool-fragment.cfg \
file://0001-update-kernel-config-to-enable-uart-console.patch \
"
But this way, the patch couldn't be applied at all. An error is caused.
3. Tried to use git to create a patch in different folder
Most of tries got the same result.
One of them seems applied. But from the result, it is actually not applied.
So, which way should work? Anything missing in what I did.
Thanks for your help!
Crane

Re: [yocto] Yocto on Raspberry Pi 3: Error when building image from a machine conf in a new layer
Yes it work. It looks simply copying the contents to the new one doesn't work. Thanks! Crane -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

[yocto] Yocto on Raspberry Pi 3: Error when building image from a machine conf in a new layer
Hello,
I am using Yocto to build a image for Raspberry Pi 3. I don't see a specific
group for RaspberryPi and hope to get help from here.
I am using Kirkstone commit and didn't download meta-openembedded as it doesn't
say it is needed in README. And it works to build a image.
Now I would like to add a new machine in the my customized layer to make some
changes based on the original machine configuration.
So I copied raspberrypi3.conf from meta-raspberrypi to my new layer first.
But bitbake displays errors as below:

I don't understand why it tries to parse core-image-testcontroller.bb, which I
don't intentionally use at all.
I am afraid that the process to create a new machine is not correct.
Does anyone can help with understanding what is missing here? Or it is not the
correct way to create a new machine for raspberrypi?
Thanks!
Crane
