Crazyflie 2.0 turns off when motors start

I can start my Crazyflie 2.0 just fine, the self test works. All LEDs light up as they should.

But when adding thrust, the flie immediately turns off.

Is this some kind of short-circuit? Or is that the issue that was addressed in the firmware update?

The other Crazyflie 2.0 I received works fine.

This might be fixed in a firmware checkin... Here's the blog post and the official release.

I would say it is a combination of the bug we fixed with the firmware Chad pointed out and maybe a depleted battery.

If you have the time, please give us feedback on how the update progress worked.

Tobias, yes, I'll do that. But for the firmware upgrade first I'll have to get the current cfclient to work (see support issue regarding the segfaults)

Yep, Marcus is working on it. Switching to SDL2 might not have been the best thing at this moment...

One good thing though is that you don't need the cfclient for the DFU update, v2014.12.0. The instructions are in the readme file in the zip.

I'll try the DFU update tonight and will let you know.

Awesome, the firmware upgrade helped!And the DFU upgrade is almost easier than via cfclient

Just a tip dbrgn. If you have the Cazyradio you can flash it directly from the build environment with "make cload". Instructions here, that is very convenient when developing.

This was news to me! But I like it.
