Hi, the bootload is not really my problem. Connection via Programmer is also not possible.
I've checkd the connections again and again.
Not i think, i have another revision from the deek robot. I really have two diffent revisions. Layout seems same but they are not from the same production.
But I've figured out that the lines in the picture at the first post are a little bit differnt as with my pro mini.
I've made a cut directly at the regulator. And that it's the problem. The connection to vcc is exactly at this position. I've checked this with a jumper wire. Bringing back the connection let the uc run.
I've attatched a photo. Red is the cut, green is the vcc connection.
