Using RPi2 image from Balena application, it won’t boot. The green led flash 7 times.
This typically means the pi boot loader cannot load the correct kernel.img. You probably downloaded the wrong balenaOS image for your device type?
You can see the docs here
Make sure you choose RPi 2.
i’m sure to using the right image. I tryied all versions (newest and oldest) no way.
For the RPi B+, you will need a separate image download. Choose the “Raspberry Pi (v1 / Zero / Zero W)” for that one.
i will try
Ok. Rp1 v1 worked for me
