MPU6000 I2C Driver on RPi


I would like to use the I2C driver on the RPi Zero W. I changed up_udelay with px4_usleep and commented the critical state part to compile it, and it goes without errors.

When I now try to access it via the command

mpu6000 -X start

it says WARN [SPI_I2C] UnknownApp: no instance started (no device on bus?)

Any idea how to fix this?
