MultiWii

Hi

I have 2 Multiwii Crius SE wich are supossed to accidentally have lost its bootloaders, as I see the leds not flashing when i power on them, and a stk500 (programmer not responding ) error when i try to flash them.

and also have a third working identical board...

I googled with no luck. Is there any step-by-step way to get to flash them the bootloader again?


Thank you

Google Search
And first alternative

Thanks, that's a good link I saw, but still confused.
I can't identify the pins shown, corresponding to Arduino UNO, with the ones in my Crius Multiwii (Arduino Pro)
Wich ones would be my ICSP port?

This is the connections on a Crius SE

Nice point, in my board there aren't "ISP" letters

Thanks!
