2.0.34 is still working fine.
I'm going to install on the ide device, cause I'm frustrated on copying
the error-messages to paper and copying again into a file.
I'm confused about the different downloading sequencer code:
2.0.34 downloading sequencer code... 413 instructions downloaded
2.2.2 downloading sequencer code... 404 instructions downloaded
2.2.5(5.1.14) downloading sequencer code... 374 instructions downloaded
more information of my system /proc error messages
