Hi all,

I was fiddling with DFU this evening and found that a MacPorts install of dfu-util 0.8.0 doesn't detect the Crazyflie 2's STM32 bootloader when it's in DFU mode. Indeed, I built 0.8.0 from source on Mac (10.11.2) and it doesn't detect the STM32 bootloader either.

I found that version 0.7.0 does work however. I haven't tried 0.8.0 on Linux yet so I don't know if this is an OS issue or a dfu-util issue.

Has anyone had a problem with dfu-util 0.8.0 on another OS?

Hi Chad,

I ran the command below on my MacOS 10.10.5 (Yosemite build 14F1509) and got the ff. output:

$ sudo dfu-util —list
dfu-util 0.8

FWIW, I ran the same command on my Bitcraze Ubuntu VM and got the same results. Perhaps you need to try running the above command, as root.

All the Best,

Thanks for running that aledda (and welcome!).

Wild! I did run it as sudo actually and still didn't ever see the STM32. But now, after I've restarted my machine, it does, in fact, show up!! I'm still not sure what happened but thanks for checking!

I've changed the title of this thread to avoid any confusion.

Code: Select all

sudo dfu-util -d 0483:df11 -a 0 -D /Users/chad/Downloads/cf2-2015.08.1.dfu

Good news to hear, Chad. I think MacOS is still working on the USB stack in El Capitan, in preparation for USB 3.1 (USB-C).
Until all the bugs are worked out, I'm sticking with Yosemite.

Best of Luck,
aledda
