Thanks KurtE, but arduino code is not solution (and not work in my case). Problem is that I can't work with putty terminal, because whenever I do anything, putty terminal always says : blablabla login:
and then Password. Of course I exactly know my password, but problem is, that is not possible write. I can only use Enter and wait for this response: Login incorect... Ha ha, of course is incorect if I cant write it
Thanks for any help.
I Solved it!!!
There is descrition ("Factory" Reset your Intel Edison/Troubleshooting Connection Problems)
How to do it? Connect micro USB to Intel Edison board (this in the corner of board). Then connect DC supply and finally run Putty on USB Serial Port. Next step is immediatelly pres any key on keyboard (for example 1) before starts autoboot, and wait for this text: boot> . Next write run do_ota. It is all.
