Build and run

One time setup

Build a Raspberry Pi 3 image using Buildroot, insert an SD card into the PC and write the image to it.

.. code-block:: shell

cd..cd .. git clone https://github.com/buildroot/buildroot.git cdbuildrootcd buildroot make raspberrypi3_defconfig makemake sudo dd if=output/images/sdcard.img of=/dev/sdX $ cd monolinux-raspberry-pi-3

Open /media/X/config.txt and replace #initramfs rootfs.cpio.gz to initramfs initramfs.cpio.

Daily development

Build this project and copy the kernel and ramdisk to the SD card, overwriting the existing files with the same name.

.. code-block:: shell

./rundocker.sh./rundocker.sh make -s -j8 exitexit cp app/build/initramfs.cpio /media/X cpapp/build/linux/arch/arm/boot/zImage/media/Xcp app/build/linux/arch/arm/boot/zImage /media/X sync

Now insert the SD card into your Raspberry Pi 3 and power it up. The console is on the serial port on the P1 header.
