Can someone please provide repo souce for debian distro? Only the link of the image is available.
there is no 'such thing'. Our Debian images are built from Debian archives directly. We pull in binary packages from Debian archives and that's what makes up our Debian images.
The images are done in 2 steps:
Most of the binary packages are pulled in from Debian archives, and we have a Linaro overlay archive with a small number of custom packages here: https://obs.linaro.org/project/show/linaro-overlay-stretch
If you have any specific question about the build jobs, please ask them here.
Thanks for such a quick response!
