Unable to reach magnetometer module in mpu9250 while using Teensy4.0 #106

Hello everyone, I am using teensy 4.0 and i connected SCL pin to 19pin of teensy and SDA pin to 18pin of teensy. There is no problem with wiring and when i uses the Basic_I2C example it comes up with an error that says "Check IMU wiring or try cycling power Status: -5". However, when i use arduino uno instead of teensy4.0, there is nothing like that problem. Sensor works as expected. In addition, when i use connection check from another library, it says that : "Searching for i2c devices... Found 1 I2C devices I2C addresses are: 0x68 I2C address 0x68 is MPU6500 and ready to use AK8963 (Magnetometer) was not found." Can anyone help me?

Try running the newest version of the library downloaded directly from GitHub. There were a bunch of fixes needed for the Teensy 4.x. It might also be the case that you don't actually have an MPU-9250 if the magnetometer is not found, in which case this library will not work.
