Syncloud image building process

We do not build our own kernels at the moment, instead we extract kernels and kernel modules from corresponding images (base images) created by board producers or board communities.

So to support new board you need to:

1. Find a good base image
2. Upload to our artifacts server (for testing you can point extractor at any url)
3. Modify extractor script to give it a name.
4. Add an identification file to files
5. Modify build script to include the new image name.
6. Build an image

sudo /path/to/drone exec --pipeline=[board-spec] --trusted

Example

sudo /path/to/drone exec --pipeline=amd64-uefi-all-buster --trusted

Example output image file in the current dir

syncloud-amd64-uefi-all-21.01.img.xz

Useful image scripts

Write an image to a device (if etcher cli is not available)

xzcat syncloud-[board]-[release].img.xz | dd of=/dev/[device] status=progress bs=4M

Virtual Box image

Convert x64 image file to a vdi file

unxz syncloud-amd64-[version].img.xz
sudo -H ./create_vbox_image.sh syncloud-amd64-[version].img
sudo chown $USER. syncloud-amd64-[version].vdi.xz
