Hi, I am wondering if there is any way to flash firmware to the crazyflie without the crazyradio PA, in UK it is out of stock from every reseller and I really want to start developing with crazyflie as soon as possible.

If you have a debug addapter the second best is to use a debugger like the st-link V2.

Otherwise you can flash the Crazyflie STM32 using the USB DFU bootloader, the procedure is documented in the wiki: ... opment:dfu.

Note that with DFU it is possible to erase the STM32 bootloader. This will prevent you from using the radio bootloader until you compile and flash the bootloader using DFU. This is nothing impossible but good to keep in mind if you want to use the radio bootloader later.
