CF2-Firmware-Dfu: Flashed without any issues
Posted: Mon Dec 22, 2014 9:11 am
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:"
doneThis is what the dfu-util output looked like when I ran the flash command.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"
For some reason, I was not able to use the bootloader/radio in the cfclient.sudo dfu-util -d 0483:df11 -a 0 -D Crazyflie2_2014.12.0.dfu
