meta-avocado

Avocado layer for Yocto

Description

AvocadOS is a composable runtime managed by Peridio.

Dependencies

• kas

Setup

Create a build directory and clone meta-avocado into that directory. In this example we create a build directory for the qemuarm64-secureboot machine.

mkdir build-qemuarm64-secureboot
cd build-qemuarm64-secureboot
git clone [email protected]/peridio/meta-avocado

Build

This repository has been officially tested for the following machines:

|------------------------|------------------------|

Name	Config
Qemu Arm64 Secureboot	qemuarm64-secureboot
i.MX6 ULL 14x14 EVK	imx6ull14x14evk
Raspberry Pi 3 - 64Bit	raspberrypi3-64
Raspberry Pi 4 - 64Bit	raspberrypi4-64
------------------------	------------------------

Machine configuration files may bring in other layers and are found at: meta-avocado-example/conf/kas/machine

To build for a machine

  kas build --update meta-avocado/meta-avocado-example/conf/kas/machine/qemuarm64-secureboot.yml

Runtime

Testing of the runtime can be done using the qemuarm64-secureboot machine. Build this configuration, then execute the following to produce the runtime artifacts:

Convert the fwup archive into an image

fwup -a \
-t complete \
-i build/tmp/deploy/images/qemuarm64-secureboot/avocado-image-base-qemuarm64-secureboot.fw \
-d build/tmp/deploy/images/qemuarm64-secureboot/avocado-image-base-qemuarm64-secureboot.img

Resize the image:

qemu-img resize --shrink -f raw build/tmp/deploy/images/qemuarm64-secureboot/avocado-image-base-qemuarm64-secureboot.img 512M

Boot the qemu machine:

qemu-system-aarch64 \
  -M virt,secure=on,highmem=off \
  -bios build/tmp/deploy/images/qemuarm64-secureboot/flash.bin \
  -cpu cortex-a53 \
