Embedded Linux Class by Mark A. Yoder

Here are instructions on how to install a current image on the BeagleBone AI.

Download Current Image

Go to https://rcn-ee.com/rootfs/bb.org/testing/ and click on the most current date. You'll see something like:

Click on buster-iot and you'll see:

Download the one that starts with am57xx and ends with .img.xz. Flash to an 8G SD card usig https://www.balena.io/etcher/.

Your SD card is ready to run on an x15, so next we update u-boot to run on an AI.

Download u-boot

Next clone the u-boot source. (jadonk is private. beagleboard is public.)

host$ git clone https://github.com/beagleboard/beaglebone-ai.git
host$ cd beaglebone-ai/SW/u-boot
host$ sudo apt install bison flex device-tree-compiler
host$ ./build.sh  # Took about 6.5 minutes

This will download u-boot and the correct compiler and compile u-boot.

host$ export DISK=/dev/mmcblk0   # Make sure this points to your SD card
host$ ./flash_mainline.sh
