I'm trying to build a linux character device for the IOT20xx and I need the correct linux header files for the example yocto image.

I can't find them in the iot2000-sdk-windows-2.1.2 .  I could use help to either locate them, or a pointer to the right process to build 'm.

Thank you.

edit: I believe, but am not sure, that I need linux-headers-4.4.13-yocto-standard
uname -r returns
4.4.13-yocto-standard

the package from github doesn't contain the generated/*.h files.

Is there an archiv that has the kernel header files for the example linux sd card image 2.1.2?

The SDK of the example image does not come with kernel headers. Would have to be enable explicitly during the build. See also http://stackoverflow.com/questions/31256770/using-populate-sdk-to-include-kernel-headers.

According to github, it seems you are already trying to rebuild the image from source, which is the cleaner way in any case: add a recipe to build your module during the image generation.

I'm trying to build my own image to include linux parts that I'd like to have running on the IOT2020: cron and sudo.

I don't plan to generate the embedded code together with the image. That is intended to be customisable to each customer's specifications. I'd like to use the SDK with Eclipse for that as much as possible (would be great if kernel headers were part of the SDK. I (think I) don't need them on the IOT2020 image).

 Now that I can successfully build the example image from source, I will try this. 

I am unsure about the following:

from http://stackoverflow.com/questions/31256770/using-populate-sdk-to-include-kernel-headers

if you want the kernel src and build system available in the SDK, you should add

TOOLCHAIN_TARGET_TASK_append = " kernel-devsrc"

to your image recipe.

I'm not sure what the correct config file is in the IOT2000 Example Image to do that

Trying it now...

edit: it didn't work

I did get this warning though, so it must have seen the addition:

I'm now trying it by following the steps here:
