=== Capability Verification and Configuration ===
The "mv_mipi_i2c_new.sh" script can be used to verify the camera’s "readmode" capabilities and configure the current settings.  

==== readmodecap ====
  If bit1 in the read value is set to 1, the camera supports 2x2 binning mode.  

==== readmode ====
  Use the following command to enable binning mode:  

  <code>./mv_mipi_i2c_new.sh -w readmode 1 -b your_i2c_bus_number</code>  

  After configuration, verify the mode with:  

  <code>./mv_mipi_i2c_new.sh -r readmode -b your_i2c_bus_number</code>  

When 2x2 binning mode is enabled, the camera automatically adjusts parameters such as maximum resolution, current ROI region, and maximum frame rate. 

Verify these parameters using:  

 <code>./mv_mipi_i2c_new.sh -r maxwh -b your_i2c_bus_number</code>

<code>./mv_mipi_i2c_new.sh -r roi -b your_i2c_bus_number</code>

<code>./mv_mipi_i2c_new.sh -r maxfps -b your_i2c_bus_number</code>

<code>./mv_mipi_i2c_new.sh -r fps -b your_i2c_bus_number</code>  

For the MV-MIPI-GMAX4002M, you can still freely configure the ROI region, frame rate, and lanenum in 2x2 binning mode.  

==== '''paramsave''' ====
  After configuring "readmode", save the settings to the camera’s non-volatile memory with:  

  <code>./mv_mipi_i2c_new.sh -w paramsave -b your_i2c_bus_number</code>  

=== Usage ===
For embedded platforms like Jetson, Raspberry Pi, and Rockchip, the camera drivers do not support direct "'''readmode'''" configuration. Use the script mentioned above.  

Recommendations:  

1. After saving the "'''readmode'''" settings, fully power off and restart the system.  

2. Upon reboot, the camera will operate in binning mode as seamlessly as in standard mode.
