Hello!

When working with the MIPI CSI-2 interface on the Verdin iMX8M Plus, there are several important aspects to consider:

  1. MCLK Configuration: Ensure that the MCLK (Master Clock) is correctly set up, as this is crucial for the MIPI CSI-2 interface to function properly. You can find more details on this in the Toradex documentation here.

  2. Camera Interface Verification:

    • The NXP i.MX 8M Plus supports a quad-lane MIPI CSI-2 interface, which is essential for high-speed data transfer.
    • It supports various color space definitions, including RGB, YUV, YCbCr, and RAW, and can handle 24-bit down to 8-bit per pixel formats. More information is available here.

  3. I2C Configuration:

    • The Verdin standard allocates specific I2C ports for the MIPI CSI-2 camera. Ensure you are using the I2C_4_CSI (I2C3) for camera communication. Details can be found here.

  4. Community Insights:

    • Some users have found that adding delays to the CSI enable sequence can resolve timing-related issues. Additionally, you might need to adjust power state initialization settings. You can read more about these experiences here.

To summarize, I recommend:

  • Verifying the use of the correct I2C bus (I2C_4_CSI/I2C3) for camera communication.
  • Reviewing the MCLK configuration and clock settings.
  • Considering the addition of initialization delays if the camera unexpectedly enters a low power state.
