embl0w-rpi

Yet another embedded Linux project for Raspberry Pi. It's based on Raspberry Pi OS (formerly Raspbian) / Debian.

Usage

Build host prerequisites: Ubuntu or Debian based Linux with 5GB free disk space.

If the host architecture is other than ARM, you will need binfmt_misc privilege or preconfigured environment to run qemu-debootstrap for ARM Linux environment.

Set up the build evironment:

$ sudo make setup

Build the boot disk image in the artifacts/image folder:

$ sudo make clean
$ time sudo make build

Write the image into a MicroSD device (make sure replacing /dev/sdb with your actual device)

$ zcat artifacts/image/boot.img.gz | sudo dd of=/dev/sdb bs=1M

Store artifacts in cloud storage using rclone

It can utilize rclone to integrate various cloud storage services such as AWS S3, Azure Blob, Google Cloud Storage. It uses artifacts: remote to upload/download artifacts at each stage. You can configure it with environment variables.

Example for Azure Blob Storage (https://embl0wartifacts.blob.core.windows.net/foobar/...):

export RCLONE_CONFIG_ARTIFACTS_TYPE=alias
export RCLONE_CONFIG_ARTIFACTS_REMOTE=azureblob:foobar
export RCLONE_CONFIG_AZUREBLOB_TYPE=azureblob
export RCLONE_CONFIG_AZUREBLOB_ACCOUNT=embl0wartifacts
export RCLONE_CONFIG_AZUREBLOB_KEY=XXXXXXXX

Example for AWS S3 (https://embl0wartifacts.s3-ap-northeast-1.amazonaws.com/foobar/...):

export RCLONE_CONFIG_ARTIFACTS_TYPE=alias
export RCLONE_CONFIG_ARTIFACTS_REMOTE=s3:embl0wartifacts/foobar
export RCLONE_CONFIG_S3_TYPE=s3
export RCLONE_CONFIG_S3_REGION=ap-northeast-1
export RCLONE_CONFIG_S3_SECRET_ACCESS_KEY_ID=XXXXXXXX
export RCLONE_CONFIG_S3_SECRET_ACCESS_KEY=XXXXXXXX

To enable rclone, you must run make build with ARTIFACTSDIR=.

$ time sudo make build ARTIFACTSDIR=
