Is the Raspberry Pi 3 Model A+ currently supported?

I am attempting to load the image on a Raspberry Pi 3A+. When I try to boot, there is no activity at all according on the green LED. I have download the image twice and verified the MD5 sum with the same results. Additionally, this Pi 3A+ works perfectly with vanilla raspbian. Also, the same SD card will boot correctly on a Pi 3 B.

I am not sure what is going on. It feels like the Pi 3 A+ is not supported. Hopefully I am doing something wrong because the Pi 3 A+ is a perfect sized Pi for an Allstar Node.

Thanks,
Karl
