+===== Linux =====
+<WRAP important >
+Edge2 CAM3 support **4K@60fps** record. If your **hardware version is V13 or later**, the **CAM2** also can support **4K@60fps** record.
+**Check Hardware Version**
+```shell
+$ cat /proc/cmdline
+```
+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''.
+Edit ''/boot/dtb/rockchip/rk3588s-khadas-edge2.dtb.overlay.env'' to setup ''fdt_overlays=cam2-4lane''.
+<tabbox Fenix 1.7.4 or older version>
+About IMX585 and IMX678, the two cameras were disabled by default. So V11 or V12 hardware version should replace ''cam2-4lane'' by ''imx585'' or ''imx678'':
+Edit ''/boot/dtb/rockchip/rk3588s-khadas-edge2.dtb.overlay.env'' to setup ''fdt_overlays=imx585'' or ''fdt_overlays=imx678''.
+V13 or later hardware version should be set ''imx585-cam2-4lane'' or ''imx678-cam2-4lane'':
+Edit ''/boot/dtb/rockchip/rk3588s-khadas-edge2.dtb.overlay.env'' to setup ''fdt_overlays=imx585-cam2-4lane'' or ''fdt_overlays=imx678-cam2-4lane''.
+<tabbox Fenix 1.7.5 or later version>
+We enbale imx585 and imx678 by default, so just add overlay node ''cam2-4lane'' can let CAM2 interface support 4K@60fsp.
+</tabbox>
+You need to reboot the device to take effect.
