Hi
I accidently downloaded wrong firmware ( e.g. a directory with files). Safe boot doesn't work, there is no LED blinking when GP28 is connected to 3.3v when exiting reset and 3.3v is disconnected from GP28. The wipy is on the expansion board and is powered by USB. Any suggestions?
Is it possible to reprogram the wipy via dfu?

PROBLEM SOLVED
Apparently the power from the USB (hub) was limited probably due to unfinnished USB negotiation. Consequently the 3.3v was around 1.5v and the CPU didn't work. By using a mains connected USB power supply, safe mode was entered correctly and erronous files were removed from /flash/sys and corect fw was download with FTP.
