thx... have more detail to the problem i think: the Bootloader switch was in "bootload" position everytime... i did because, in this position it booted up normal - so i guessed... now after i give it that 330ohm resistors R102 R101, --- it dont boots up in the same position because it is in "real" bootload position.... after switching it to the other side the problem is gone! ---good to have a functional bootloadswitch in this time... because in some month when i need it in real (hacking into code maybe) - i would come in some serios trouble - because of thinking the switch do its job - and the MCU which is fix soldered - is gone or something THX
