Problem booting Raspberry Pi OS with Mender integrated

I flashed a 16GB SD card with Mender-integrated Raspberry Pi OS. I am using a Raspberry Pi B+. But while booting, a rainbow screen appears and would not continue further.

I have tried flashing the OS image from BalenaEtcher and Raspberry Pi Imager tools. Both result the same. Can anybody help me?

Which image exactly are you trying to flash? Did you download out from our resource or did you build it your self?

We only have images for Raspberry Pi 3 & 4.
