Hi Guys, I did 'erase chip' the NRF port of crazyflie through j-flash.
As a result, the NRF's firmware is gone and there is no power nothing .
Can i know how to flash the initial firmware in this case?"
The firmware does not flash and power up through the VM, so it does not even Connect to the client.

Hi,
Do you have a Crazyflie 2.0 or 2.1?

If you have a 2.0, you can recover the nRF by running "make factory_reset" in the crazyflie2-nrf-firmware project: https://github.com/bitcraze/crazyflie2- ... #compiling. For Crazyflie 2.1, you can use "make factory_reset_21"

In both case it is important that the Crazyflie is only powered using a battery when flashing the full nRF. If you have empty batteries, even when the nRF is reset, plugging the battery and a USB port is charging the battery slowly.
