M2 stays solid blue. No other LEDs lighting

Post by nikonlivin » Sun Mar 22, 2020 11:06 am

Hi, when I turn on my crazyflie only M2 lights up solid. If i try to put it on bootloader mode, only m2 blinks. I tried to flash the bootloader while in DFU mode and was able to update the firmware using the bootloader after that. But when I reset it in firmware mode, the same thing happens again where only M2 lights up. Please help.

The nRF51 MCU firmware has probably been corrupted. Start from a powerless state and you should be able to get into the bootloader. Thus hold the button while connecting the battery.
