[Help] Installing BalenaOS on NPE X500 M3

Ok I tried creating a NPE X500 m3 appliction and following the process.

If I connect an screen to the device I see a login prompt for “techbase” in tty1.
This is not what I expected to happen. I would have expected this image to just be flashed to the device and then the device would register itself inside balenaCloud.

Can I also take a RPI3 or 4 image to put on the device?

Also I don’t seem to be able to get the device to boot any other image now, it keeps showing the purple RPI logo with techbase login. I really mean purple, not pink like the normal RPI image.
