rk3x-i2c ff150000.i2c: timeout, ipd: 0x80, state: 2
This error message indicates that the I2C communication between the RK3X-I2C device and the processor has timed out. The "ipd" value of 0x80 suggests that the device is not responding to the processor's requests.
The "state" value of 2 indicates that the I2C driver is currently in the "receiving data" state, meaning that it is waiting for the device to send data back to the processor. However, since the device is not responding, the driver has timed out and is unable to complete the communication.
Possible causes for this error include a faulty device or a problem with the I2C bus. It may also be caused by incorrect settings in the device driver or a software issue. Troubleshooting steps may include checking the wiring and connections, verifying the device's address, and checking for any known software issues or bugs.
