Hi,
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?
Best,
Julian
