Hi I am from India, Bus Blaster is not available here. So I bought ST-Link V2 (st link v2). Can it be used to flash/debug crazyflie? If yes, any reference how to do it?

Hi,
Yes sure ST-Link V2 works fine. You need to change OpenOCD config files in the Makefile:
https://github.com/bitcraze/crazyflie-f ... kefile#L10
The easiest way to do that is to create a config.mk file and put this in it:
Code: Select all
OPENOCD_INTERFACE = interface/stlink-v2.cfg
OPENOCD_TARGET = target/stm32f1x_stlink.cfg
CLOAD=0
Note that to flash with JTAG you have to flash the firmware without bootloader support. When you are finished you can flash back the bootloader (the project is on GitHub) and build with CLOAD=1 to bootload your new firmware.

Hello. Can someone explain me how to connect crazyflie to st-link? I use st-link from stm32 discovery board.
I powered my copter from li-ion battery:
3v3 ----- li-ion 3v3
GND ---- li-ion GND
On discovery board i have 4 pins that i need to connect to crazyflie:
---------------------------------------------------------------------|
discovery ------------- crazyflie expansion board
---------------------------------------------------------------------|
VDD_TARGET ------------ Pin 1 ( VCC )
SWCLK ---------------------- Pin 4 ( TCK )
GND --------------------------- Pin 9 ( DGND )
SWDIO ----------------------- Pin 2 ( TMS )
---------------------------------------------------------------------|
This is the proper connection? This connection will not destroy my copter?
