Hi

I followed the wiki page to flash firmware for "crazeflie + uwb deck".

: crazeflie with deck, hardware connection

When connected to PC, its device name can be found,

Bus 002 Device 002: ID 8087:8000 Intel Corp.
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 8087:8008 Intel Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 017: ID 0483:df11 STMicroelectronics STM Device in DFU Mode
Bus 003 Device 003: ID 062a:4101 Creative Labs Wireless Keyboard/Mouse
Bus 003 Device 002: ID 1b1c:1b36 Corsair
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

The firmware is compiled successful. Then, I tried

Code: Select all

sudo dfu-util -d 0483:df11 -a 0 -s 0x08004000 -D cf2.bin

Code: Select all

sudo dfu-util -d 0483:df11 -a 0 -D cf2.dfu

It shows,

dfu-util 0.8

The crazeflie has one blue LED(M2) blink during the entire process. There isn't other LED signal showed.
I'm not sure whether firmware is downloaded correct.

Since my crazyradio PA doesn't work at the moment, I can't check its flying.

Thanks

You are flashing using the DFU mode which is intended as a recovery mode mainly, the preferred way is to flash using the radio bootloader with make cload. It is normal that in DFU mode no other LED are light-up.

Your console copy-paste shows that the programming has been done successfully. You can then reset the Crazyflie by pushing the power switch or power-cycling the board (ie. remove USB and battery and plug back the battery). If your flashing worked well you should see a normal startup sequence (https://www.bitcraze.io/getting-started ... -2-0/#test).
