The picture shows the console tab with no errors but when you have an error it might say e.g //MPU6050: Self test acc Y [FAIL]. low: 0.300000, high: 0.949999, measured: 0.0.// This example means that the accelerometer Y axis didn't pass the self test and is probably defective. It is possible to get 5 blink error also if the Crazyflie is moved to much during the self test, so try putting it on a sable surface before you power it on. | The picture shows the console tab with no errors but when you have an error it might say e.g //MPU6050: Self test acc Y [FAIL]. low: 0.300000, high: 0.949999, measured: 0.0.// This example means that the accelerometer Y axis didn't pass the self test and is probably defective.

If you get errors during the upgrade or you upgrade to your own custom software that has bugs you might not be able to start the firmware. The typical behaviour for this during power on is that the red/gre LEDs blink and then nothing else happens. No sensor test is run (i.e no more blinking LEDs) and you cannot connect with the Crazyradio. | If you get errors during the upgrade or you upgrade to your own custom software that has bugs you might not be able to start the firmware.
