To be able to debug the Crazyflie 1.0 using JTAG you will need to solder the extra connector that is packaged with the Crazyflie on pins 1-10 on the EXT connector <insert image>. You will also need a JTAG debugger. The virtual machine is pre-configured to use the STLink v2 but can be set-up with any JTAG device that openOCD supports.
The debug adapter is needed (or a cable could be made) to convert the ARM 20pin JTAG connector to the 6pin JST connector used on the Crazyflie 2.0. You will also need a JTAG/SWD debugger. The virtual machine is pre-configured to use the STLink v2 but can be set-up with any JTAG/SWD device that openOCD supports.
The STM32F405 debug connector is located under the micro USB connector.
The nRF51 connector on the other hand needs to be soldered as part of the debug adapter kit. However you can probably do with just updating this using the radio bootloader as most of the development is done on the STM32F405.
In order to start debugging do the followning:
