Where can I download debian stretch for dragonboard 410c

Where can i download a stable debian stretch image for dragon board 410c.

17.09 was the last Debian release based on stretch but I really wouldn’t
recommend using it. You are likely to encounter significant WiFi
problems unless you adopt a custom (e.g. updated to latest) kernel and
some of the userspace packages (gps, gstreamer, etc) may suffer version
skew problems that you would also have to correct.

Thank you for reply.

What is the most stable image at the moment?

Latest stable image is 19.01 .
