This error is from building https://github.com/bitcraze/crazyflie2-nrf-firmware. Can you clone that repo by itself and build it? (see https://www.bitcraze.io/documentation/repository/crazyflie-firmware/2020.04/building-and-flashing/build_instructions/, https://github.com/bitcraze/crazyflie2-nrf-firmware/blob/master/docs/build/build.md). If not, resolve that problem first.

Alternatively, you could skip the firmware build and use the prebuilt binaries in https://github.com/USC-ACTLab/crazyswarm/tree/master/prebuilt. You can comment out the "build *** firmware" steps in build.sh.
