Dear all,
first - I use Diet a very long time and using it to power my Raspberry Pi Zero - Managing all my Homebridgedevices 
I ordered a NanoPi M2 board (cause it has 4 cpus and the price was so good…
But now I even can’t get this little sbc booting…
I have no clue what I’m doing wrong…
I downloaded the 7z.image
https://dietpi.com/downloads/images/DietPi_NanoPiM2-ARMv7-Bullseye.7z
Then used balenaEtcher to write to sd-card
then I power on and no blinking blue led 
Can anyone give me an advice???
And I can’t find the new beta image 8.4 for the M2 as well
Thank you very much for any advice
Please be patient with me
