Self test started to fail after some flight

Hi,
I've bought a Crazyflie 2.0 about two years ago, but since I had a Crazyflie 1.0, I simply didn't use the 2.0 until this year.
I tested it and everything was fine, I even was able to put it to fly. In one of the flights, the motors suddenly went to full thrust (not by my command) and I turned the Crazyflie off. When I restarted it, it wasn't passing anymore in the self test. I tried to reload the firmware although it doesn't seem to be the problem, and indeed nothing changed,

Here is the log:

Code: Select all

CFGBLK: v1, verification [OK]
MPU9250 I2C connection [FAIL].
AK8963 I2C connection [FAIL].
LPS25H I2C connection [FAIL].
DECK_DRIVERS: Found 9 drivers
DECK_INFO: Found 0 deck memory.
DECK_CORE: 0 deck enumerated
EEPROM: I2C connection [OK].
MPU6500: Self test gyro Y [FAIL]. low: -14.0, high: 14.0, measured: -100.0
Any ideias of how I could fix this? (Is it fixable?)

Thanks in advance.

Probably a known case of a badly soldered sensor. Please check out this forum post for possible solutions.
