Flashing the Image on MicroSD Card
Output Image location in build machine for Raspberry Pi 4:
tmp/deploy/images/raspberrypi4-64/agl-demo-platform-raspberrypi4-64.wic.xz
Extract the wic.xz and flash it on a microSD card
sudo umount [sdcard device]
xzcat [output image] | sudo dd of=[sdcard device] bs=4M status=progress
sync
Plug the microSD card in the Raspberry Pi and turn in on (the first boot of AGL
takes a bit longer)](https://image.slidesharecdn.com/leon-anavi-getting-started-with-agl-using-a-rpi-amm-2020-200721130547/85/Getting-started-with-AGL-using-a-Raspberry-Pi-13-320.jpg)
