The x8h7 kernel module source files can be found here: build-lmp-base/tmp-lmp_base/work/portenta_x8-lmp-linux/x8h7/0.1-r1/git and can be locally edited there.
bitbake -c do_compile (force the compilation or configure with the modifications you just did in WORKDIR) (and withouth -c do_cleansstate)bitbake -c do_compile -f x8h7 && bitbake -c do_install x8h7
The compiled kernel modules can be found here: build-lmp-base/tmp-lmp_base/work/portenta_x8-lmp-linux/x8h7/0.1-r1/image/usr/lib/modules/6.1.24-lmp-standard/extra.
Note: it is not always obvious what is the final value of any given Yocto variable, since they can be overwritten from different layers. It is therefore highly recommended to check the value with bitbake-getvar.
bitbake-getvar -r <image> <variable>
i.e. bitbake-getvar -r lmp-devel-arduino-image USERADD_GID_TABLES .
