A prompt as below indicates that the MV-MIPI-IMX296M camera is detected on the i2c-7 bus.

<code>mvcam 7-003b: camera is：MV-MIPI-IMX296M</code>

<code>mvcam 2-003b: camera is：MV-MIPI-IMX296M</code>

<code>mvcam 7-003b: firmware version: 0x1290133</code>

<code>mvcam 2-003b: firmware version: 0x1290133</code>

For Radxa Zero 3W, the camera is connected to i2c-2.

 

On the ROC-RK3566-PC, the camera is mounted on i2c-4.

===Raw data format===

The VICAP module of RK3588 supports two data saving formats, Compact and Noncompact RAW. You can modify the mode using the RKCIF_CMD_SET_CSI_MEMORY_MODE ioctl command of RKCIF. By default, the output is in Compact RAW format.[[File:Compact raw and noncompact raw of rk3588 vicap.png|center|thumb|800x800px|Compact raw and noncompact raw of rk3588 VICAP|link=http://wiki.veye.cc/index.php/File:Compact_raw_and_noncompact_raw_of_rk3588_vicap.png]]

For pixel data with 10-bit depth or 12-bit depth, two bytes are always used to store one pixel. This storage method is convenient for software processing, but it has the disadvantage of occupying a large amount of space.
