Yes, it is too weak!! I also have that experience... I hope they resolve this issue for the next version of crazyflie. In my case, I just soldered.. but it was very hard for me. Because the working space of cf2 is narrow and the wire hole is very tiny, it is hard to solder. Moreover, solder does not...

Oh...I understood...

I installed , and executed in crazyflie2-stm-bootloader folder.

Finally, I got cf2 Bootloader mode with pressing power button for 3 secs....

I really appreciate it!!

Hi, arnaud recently I receive stlink, and try flash stm-stm-bootloader.. The result, however, is shown in the following.. ~/crazyflie2-stm-bootloader$ lsusb Bus 002 Device 021: ID 0483:3748 STMicroelectronics ST-LINK/V2 Bus 002 Device 002: ID 8087:0024 Intel Corp.

Thank you for your reply.

Do you think the following is okay?

Thank you.

Hi arnaud, sorry for my tardy reply. The link you gave me does not work. As I already mentioned, there is no dfu mode devide detected when I run "lsusb" When I flashed PX4, I followed the link; https://docs.px4.io/en/flight_controller/crazyflie2.html I used the usb cable and dfu mode, not ...

Yes, I can make the LED blink very fast (about 1Hz) like a DFU mode by pressing the button for 5 sec. However, $ lsusb did not show any DFU mode device as I said in the previous post. The output is shown in the following. ubuntu:~$ lsusb Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate M...

Hi arnaud, The one crazyflie which can be enter DFU mode is working with official firmware by following your instruction. After running the following command, I did not know that it can be get bootloader mode by pressing the button for 3 sec. sudo dfu-util -d 0483:df11 -a 0 -s 0x08000000 -D cf2loade...

Okay thank you for your reply. Firstly, the answer in regard to the DFU bootloader, yes, No.1 cf2 can get the DFU bootloader mode blinking LED quickly. I executed the following code to flash STM bootloader and get the results shown in the following. $ sudo dfu-util -d 0483:df11 -a 0 -s 0x08000000 -D...

Hi, arnaud!

Do you have any advice for me?

Hi, thanks for your reply. I tried to flash px4 into cf2 before. I used the bootloader in this page. cf2 px4 : https://docs.px4.io/en/flight_controller/crazyflie2.html bootloader : https://github.com/PX4/Bootloader It worked well, but I decided to back to bitcraze firmware, so I used bin files and v...
