[SOLVED] CF2 doesn't boot after failed iphone firmware flash

Post by andrew »

Hello,

I was attempting to update the firmware of a CF2 with the iphone app but got a bit impatient and pressed the cancel button after I realized how long it was taking (I figured if there was a cancel button, it would be fine). Alas, it was not fine. After restarting the CF, the only thing that turned on was M2.

No blinking on M2 and no blinking of the red and green leds that I have heard indicate the boot-loader starting. I held down the power button to try and coerce it into boot mode but nothing happened.

After looking around I found the DFU boot mode. I could get into DFU mode and I followed the instructions on

https://wiki.bitcraze.io/projects:crazy ... opment:dfu
(with output shown at the bottom of the post)

but neither the bootloader nor the crazyflie firmware bins fixed the problem.

If anyone has any idea what is going on, I would welcome the help. I think it may be the nRF firmware thats the problem.

Thanks!
