CF2-Firmware-Dfu: Flashed without any issues

[lxrocks]

Hi
I thought I would share this as it took a while to get the CF2 into dfu mode though. Mostly because the switch is so small I had no idea if I was pressing it on or not I was also worried the switch might break.

Because I was having issues getting it into DFU mode I ran dfu-util -l in a loop until I saw Found DFU: [0483:df11] in the output. I now know that only the M2 Blue led will flash as it goes into DFU mode. Once the switch is released, it seems to go on solid, then slowly starts to blink getting quicker until stays at a steady blink.

eg

Code: Select all

while sleep 2
do
  dfu-util -l | egrep -i "Found DFU:"
done

Found DFU: [0483:df11] devnum=0, cfg=1, intf=0, alt=0, name="@Internal Flash /0x08000000/04*016Kg,01*064Kg,07*128Kg"
Found DFU: [0483:df11] devnum=0, cfg=1, intf=0, alt=1, name="@Option Bytes /0x1FFFC000/01*016 e"
Found DFU: [0483:df11] devnum=0, cfg=1, intf=0, alt=2, name="@OTP Memory /0x1FFF7800/01*512 e,01*016 e"
Found DFU: [0483:df11] devnum=0, cfg=1, intf=0, alt=3, name="@Device Feature/0xFFFF0000/01*004 e"

This is what the dfu-util output looked like when I ran the flash command.

sudo dfu-util -d 0483:df11 -a 0 -D Crazyflie2_2014.12.0.dfu
dfu-util 0.7

For some reason, I was not able to use the bootloader/radio in the cfclient.

The radio bootloader instruction are not really up to date. Working on them now so let's hope it works with the right instructions.

I've updated the instructions now if you would like to try.

Thanks I will give it a try. I am still struggling with my 'fat-fingers' to push that button and know that it has made contact
