+V13 or later version will show like ''hwver=EDGE2.V13''.
 Due to the different hardware versions, **CAM2 is set to 4K@30fps by default**. This is for compatibility with V11 or V12 hardware versions to
 ensure proper operation. If your device supports 4K@60fps, you can enable this mode by adding an overlay node ''cam2-4lane''.
-```shell
-$ sudo vim /boot/dtb/rockchip/rk3588s-khadas-edge2.dtb.overlay.env
-fdt_overlays=cam2-4lane

-About IMX585 and IMX678, the two cameras were disabled by default for compatible problem. So V11 or V12 hardware version should replace ''cam2-4lane'' by ''imx585'' or ''imx678''
