Support for BCM2835 GPIOs `-> however we stick to default and just build it as module and load it at boot in /etc/rc.local GPIO controller => with " GPIO controller " instead it builds directly in kernel, then no need to load module anymore!

apply a patch for pinctrl-bcm2835.c : pinctrl-bcm2835.c.patch (see above how we get this) # `-> xenomai script which does patch `-> kernel source where patch applied `-> ipipe patch file for kernel source Xenomai-3.0.8/scripts/prepare-kernel.sh -linux=linux/ -arch=arm -ipipe=ipipe-core-4.9.51-arm-4.fixedforrasbian-4.9.80.patch Which otherwise makes packages with broken links!! (see linux headers below) => this is needed for 'make deb-pkg' in the linux kernel source tree => instead of soft linking the xenomai files in the linux src tree # finally really apply both xenomai and ipipe patch to kernelĮdit xenomai-3.0.8/scripts/prepare-kernel.shĪnd change the 'ln -sf' command into a 'cp' command # as already described above the raspbian patch is better for this file then the ipipe-4.9.y version. # note: in this fixed patch we removed all patches for drivers/pinctrl/bcm/pinctrl-bcm2835.c because # you can download this fixed patch with the command : # so we manually patched the patch file which gives us the new patch file: Patch -dry-run -p1 look at FAILED messages in patch output!! # first check if the ipipe patch applies well: (because little bit different kernel) apply xenomai (and ipipe) patch to kernel and linux/drivers/pinctrl/bcm/pinctrl-bcm2835.c ) apply kernel patches ( xenomai+ipipe, bcm( arch/arm/mach-bcm2709/. # In the file how_pinctrl-bcm2835_patch_is_derived/_README_.txt we describe how we derived this file.Ģ. we derived a new patch for pinctrl-bcm2835.c for raspbian 4.9 kernel : pinctrl-bcm2835.c.rpi-4.9.patch get ipipe patch (effects both kernel and some drivers(using interrupts)) get xenomai source (effects only linux kernel)

# which gives 4.9.80 which is full version -> number also used for directory for in /lib/modules/ # just verify kernelversion with a make command: We can then put both images on the sd-card and on boot the bootloader will automatically load the right kernel for the specific raspbian hardware board. However using a different default config for the kernel build we can also easily build an image for rpi1 and rpi zero. But not on the rpi1 and rpi zero because they have a different type of ARM processor (ARM1176JZF-S/ARMv6Z). Note that this image also works on all other rpi3's and rpi2's (Cortex-A7/ARMv7 and Cortex-A53/ARMv8 cpu's are compatible).
