![]() You will then need to build the Android RPi kernel using the instructions available from that group. $ sudo cp out/target/product/rpi4_car/ramdisk.img /mnt $ sudo cp device/snappautomotive/rpi4_car/boot/* /mnt You will then need to mount p1 to copy the boot files to it, you can use the following commands $ sudo mount /dev/ /mnt You will also need to create filesystems on p1 and p4 using the following commands $ sudo mkfs.vfat /dev/ $ sudo dd if=out/target/product/rpi4_car/vendor.img of=/dev/ bs=1M Once your build has been completed you can write the disk images to p2 and p4 using the following commands $ sudo dd if=out/target/product/rpi4_car/system.img of=/dev/ bs=1M You will then need to partition the SD card with the following layout using fdisk ![]() This will create the disk images you will need to create a bootable SD card. The build instructions are available in the README file in the device repository, and consist of these steps $ source build/envsetup.sh ![]() $ sudo apt install meson python3-setuptools To obtain the source code for the build you will need to perform the following steps, which are also in the README in the repository. This means there is no need to select one build or the other and allows you to test any updates from the Android RPi project in the same checkout as our AAOS build. ![]() For this reason we recommend using the -eng build variant and a serial console (as discussed in the original AAOS 11 post), to ensure you can debug issues you may encounter.įor AAOS 13 we have altered how we create the build targets to allow folk to place our AAOS build files, and the Android RPi build (on which it’s based), side-by-side. We are releasing it as a starting point for people to work with, rather than holding it back until it is in a consumer-friendly state. Our AAOS 13 Raspberry Pi build is designed for the development community to work with, and, for now, you will need to build the disk images yourself, and the end result is not a fully functioning product. Since making the AAOS 11 build available we’ve seen a lot of interest in Raspberry Pi AAOS builds from various groups, and, while we do not feel that the RPi 4B is a good platform for automotive devices, we understand that the development community likes to experiment with ideas, and the RPi4 provides an easy way to do this. Today we’re making AAOS 13 available for the same platform. Nearly two years ago we released details of how to build Android Automotive OS 11 for the Raspberry Pi 4B to give folk a cheap and easy way to run it on actual hardware. ![]()
