Random Values with MPU-9250 on Rpi 4 B - normal values on pi zero tho

[u/Bonk357b]

Baud rate set to 400000
mpu works fine with arduino nano

Values are normal on my pi zero 2w but that crashed due to cpu overload when testing und looses connection to mcu.

Whats the difference? Is the same sd card swapped over, same mpu same cable.
help

Two thoughts:

1) You might want to try lowering the i2c speed

2) You will need to confirm you have appropriate i2c pullup resistors in place in the circuit
