Oh I understood, I need to add the C1 on each Atmega 3V3 supply. --> blocking <https://dict.leo.org/ende/index_de.html#/search=blocking&searchLoc=0&resultOrder=basic&multiwordShowSingle=on> capacitor <https://dict.leo.org/ende/index_de.html#/search=capacitor&searchLoc=0&resultOrder=basic&multiwordShowSingle=on> But could that really be the issue which stopps the BBB running. I can also not boot the beagle up when I have removed the cape. When I want to boot up the beagle alone the power led flashes up one time...and thats it....
