-===== Identify VIM4 Version =====+===== Different VIM4 Versions =====
  
 <WRAP important > <WRAP important >
- +There are two [[../configurations/identify-version#vim4-versions-differences-reference-table| different VIM4 versions ]]: VIM4 and New VIM4. Both versions have different [[/tag/isp|ISP IP core]], so the usage of MIPI camera is also different.
-There are two versions of **VIM4**, they are **VIM4** and **New VIM4**, as they have different ISP IP core, so the usage of MIPI camera is also different, +
-please follow the documentation to identify your VIM4 version and choose the right documentation for your VIM4. +

-===== New VIM4 MIPI Camera Usage ===== +
- +
-==== Enable Overlays ==== +
- +
-If you want to use the OS08A10 MIPI camera, you need to enable it in [[products:sbc:vim4:configurations:device-tree-overlay|overlays]], you need to add ''vim4n-os08a10'' to ''fdt_overlays'' in ''/boot/dtb/amlogic/kvim4.dtb.overlay.env''. +
- +
-``` +
-$ cat /boot/dtb/amlogic/kvim4.dtb.overlay.env  +
-fdt_overlays=vim4n-os08a10 +
-``` +
- +
-And then reboot to take effect. +
- +
-==== Video Node ==== +
- +
-The video node is ''/dev/media0''. +
- +
-==== Get Frames via Mediactl API ==== +
- +
-You can get the test source code here: https://github.com/numbqq/v4l2_media_test +
- +
-Download and build the test source code: +
- +
-<tabbox 5.4 kernel> +
- +
- +
-```shell +
-$ git clone https://github.com/numbqq/v4l2_media_test +
-$ cd v4l2_media_test +
-$ git checkout e0482794337c01935593a91b621f9c42123cf175 +
-$ g++ v4l2_test_raw.cpp -o v4l2_test_raw  -Wall -Wno-int-to-pointer-cast -Wno-pointer-to-int-cast -pthread -fPIE -lispaml -ldl -lmediaAPI -ltuning -lm -fPIC -D_FORTIFY_SOURCE=2 -O3 +
-$ ls v4l2_test_raw +
-v4l2_test_raw +
-``` +
- +
-<tabbox 5.15 kernel> +
- +
-```shell +
-$ git clone https://github.com/numbqq/v4l2_media_test +
-$ cd v4l2_media_test +
-$ g++ v4l2_test_raw.cpp -o v4l2_test_raw  -Wall -Wno-int-to-pointer-cast -Wno-pointer-to-int-cast -pthread -fPIE -lispaml -ldl -lmediaAPI -ltuning -llens -lm -fPIC -D_FORTIFY_SOURCE=2 -O3 +
-$ ls v4l2_test_raw +
-v4l2_test_raw +
-``` +
- +
-</tabbox> +
- +
-Test: +
- +
-```shell +
-$ ./v4l2_test_raw -p 0 -n 10 -m /dev/media0 +
-``` +
- +
-It will capture 10 frames to file ''/tmp/dst_mif_0.yuv''. +
- +
-Preview the file: +
- +
-```shell +
-$ ffplay -f rawvideo -pixel_format nv21 -video_size 3840x2160 /tmp/dst_mif_0.yuv +
- +
-```+
