Ok it seems that wasn't all connected correct. But it works still not
accurate. The -B option works only with values greater than 140. Then i
can flash only with the -D option and the flash process stucks by the
message

"avrdude: safemode: Fuses OK (H:FF, E:FF, L:6A)"

and comes not back to the console.
