The P4wnp1 needs the groups added before the system boots for the first time, because the udev rules happen earlier, so add them in here instead of in the bsp

# Note: Compiling the kernel in /usr/src/kernel of the target file system is problematic, as the binaries of the compiling host architecture
|
|
# get deployed to the /usr/src/kernel/scripts subfolder (in this case linux-x64 binaries), which is symlinked to /usr/src/build later on
|
|
# This would f.e. hinder rebuilding single modules, like nexmon's brcmfmac driver, on the Pi itself (online compilation)
|
|
# The cause:building of modules relies on the pre-built binaries in /usr/src/build folder. But the helper binaries are compiled with the
|
|
# HOST toolchain and not with the crosscompiler toolchain (f.e. /usr/src/kernel/script/basic/fixdep would end up as x64 binary, as this helper
|
|
# is not compiled with the CROSS toolchain). As those scripts are used druing module build, it wouldn't work to build on the pi, later on,
|
|
# without recompiling the helper binaries with the proper crosscompiler toolchain
|
|
#
|
|
# To account for that, the 'script' subfolder could be rebuild on the target (online) by running `make scripts/` from /usr/src/kernel folder
|
|
# Rebuilding the script, again, depends on additional tooling, like `bc` binary, which has to be installed
|
|
#
|
|
# Currently the step of recompiling the kernel/scripts folder has to be done manually online, but it should be possible to do it after kernel
|
|
# build, by setting the host compiler (CC) to the gcc of the linaro-arm-linux-gnueabihf-raspbian-x64 toolchain (not only the CROSS_COMPILE)
|
|
# The problem is, that the used linaro toolchain builds for armhf (not a problem for kernel, as there're no dependencies on hf librearies),
|
|
# but the debian packages (and the provided gcc) are armel
|
|
#
|
|
# To clean up this whole "armel" vs "armhf" mess, the kernel should be compiled with a armel toolchain (best choice would be the toolchain
|
|
# which is used to build the kali armel packages itself, which is hopefully available for linux-x64)
|
|
