Not working anymore after firmware upgrade

Hi,
I have upgraded the Otii to the latest firmware (everything seems ok in the console) and now it cannot boot up. I can just hear a click every second like it was reseting during boot time.
Any idea ?
Thanks in advance

Hi,

This sounds strange.
Please create a case so we can investigate this further.

Best regards,
Björn

Thanks Björn, I created a case and I just ordered à 9V adapter to see if this change anything.
Best regards
