Hello,

I am customizing a driver for the Arducam 64MP (B0399 Hawkeye) on a Jetson Orin Nano Developer Kit. The driver probe completes successfully, but during sensor initialization I encounter I2C no-ACK errors.

It appears that the sensor chip ID is not being read correctly, which is likely causing the initialization failure.

Issues / Questions

  1. Unknown sensor model
  • The exact sensor (e.g., IMXxxx) used in this module is not clearly documented.
  • Without this information, it is difficult to verify the correct chip ID registers or driver compatibility.
  1. Chip ID read failure
  • Since this may be a proprietary module, standard register read methods are not returning valid data.
  • I am unsure how to properly read the chip ID for this sensor.
  1. Debugging I2C no-ACK
  • What is the recommended way to:
    • Read the chip ID (via i2cget, i2cdump, or driver-level access)?
    • Debug and resolve I2C no-ACK issues on Jetson?
  • Could this be related to:
    • Incorrect I2C address
    • Power/reset sequence
    • Device tree misconfiguration

Terminal Output

DT device 9-001a exists 
Mux GPIO (PCC.03) = channel 1 
MCLK enable count = 8 
Driver bound 
Sensor ACK at 0x1a   DEAD

Goal

To successfully read the sensor chip ID and resolve the I2C communication issue so the driver can properly initialize the camera.

Hi there,
Could you please provide more terminal logs so we can inspect further?
