[SOLVED] Flashing Crazyflie Firmware

[ArthurA]

Hey,
I got my CF 2 yesterday for christmas and I'm extremely pleased with it so far

I'm having a bit of a problem with flashing the latest firmware. I can build it fine, but when I try to flash it I get this:

Code: Select all

12:12:29 **** Build of configuration Default for project crazyflie-firmware ****
make cload 
../crazyflie-clients-python/bin/cfloader flash cflie.bin
Restart the CrazyFlie you want to bootload in the next  10 seconds ...
make: *** [cload] Error 255
Cannot connect the bootloader!

12:12:43 Build Finished (took 13s.730ms)

The strange thins is the

Code: Select all

../crazyflie-clients-python/bin/cfloader flash cflie.bin

line hangs for a few seconds, and then all of the rest appears with the error message...
I reset the CF while that line is running like here: https://www.youtube.com/watch?v=chWrNh73YBw, but it still doesn't work.

Anyone know why this could be?

[ArthurA]

Oh yes, and I'm running this in the VM rev 0.5 with all of the repos updated.

We just released WM 0.6. I don't think it works in 0.5 without a lot of modifications.

Oh I didn't know that. The reason that I haven't been using 0.6 is that I can't download it- when I click on any of the links (torrent or direct) I just get Welcome to nginx!. Is that an access problem???

[tobias]

Yep, definitely something wrong with the access rights. I'll send an email to Arnaud an hope he can fix it quickly.

[chonchonchon]

same for me : Welcome to nginx!

The new VM i now uploaded here. But looking at the printout in your initial post you are probably on the wrong crayflie-firmware branch, you should switch to the crazyflie2 branch if you want to build the firmware for the Crazyflie 2.0. There's a missing parameter for the cfloader script on the main branch for the Crazyflie 1.0, I've added an issue here for bootloading the CF1.

Just got my new crazyradio in the post (I broke my old one) and tried flashing the crazyflie with it using the vm 0.6, but it still doesn't work, even after updating the repos. Here are the errors:

^^ I did click the all (no ble) option first if that makes a difference.

Any ideas?

Edit: I also can connect to the crazyflie via the client, so i have all of that configured.

You are trying to flash the STM32 firmware, right? And you're using the Crazyradio to flash (i.e. over-the-air)?

Inside the crazyflie-firmware directory, if I do:

Code: Select all

make clean; make

And then do:

Code: Select all

make cload

Then turn on the Crazyflie in bootloader mode (hold down power button for 3 seconds until blue light flashes) and wait a few seconds until it flashes. It seems to work ok for me. Does this work for you?

Here's some more info about OTA flashing on the wiki.

Thanks Chad, I forgot I had to put the flie in bootloader mode *facepalm*.
