I was flashing the stock v5.5 controller. But I was not able to flash it and got an error from the flash software. After that the board shows no response when I connect esc's or usbasp programming cable, led is not blinking.  Please help..

What was the error you had encountered, and are you sure you didnt reverse polarity or connect wrong pins up while flashing or powering up after failed flash attempt. Because if its not powering up at all, its kind of dead. Try to power it with different esc/usb port/cable etc

I tried using libusb and kk flash utitlity and it worked like a charm. Now the board is flashed with kk blackboard 16kb flash..

avrdude.exe done.  Thank you.

Flash the firmware from repository.

Error during setting the fuses.
Flashing of firmware aborted.

i encounter this problem can anyone help with this

Yes i had the same problem.. You need to download libusb ~1.2 then follow these steps



just verify the polarity of the usbasp cable. Tiny arrow on the jack should be up against vcc (board).

now i get this prob can anyone help

Please specify the operating system you are using. I was facing issues with windows 8 but i am not facing any issue in windows 7.

You have to download latest drivers from here
http://www.fischl.de/usbasp/

Download latest flash tool from here
http://lazyzero.de/en/modellbau/kkmulticopterflashtool

libusb from here
http://sourceforge.net/projects/libusb-win32/

then follow the instruction as depicted in the video.

Also verify your drivers from device manager. A successfully installed usbasp should look like this..

hi,
i am using windows 7 os first problem was cleared when i followed the steps in the video, now i am facing a problem regarding device signature is there any solution

have you successfully installed lipusb drivers and make sure that the driver should work even after you connect your board to the cable.
