我們在進行 S32V 環境開發時，常常會需要額外從 VSDK 那邊再 build 出 3rd party 的 lib 然後 copy 至板端的 rootfs 裡面，過程上其實也不難，但趕時間的時候還是會覺得細節惱人，以下提供一個方法來簡化這段流程。
1. 先準備好 OpenCV，ffmpeg，kernel module 等 .so & .ko 檔案：
2. 建立複製 OpenCV，ffmpeg，kernel module 等 .so & .ko 檔案的 recipe：
cd /sources/meta-alb
mkdir -p recipes-wpi && \
mkdir -p recipes-wpi/copy-so-ko-files && \
mkdir -p recipes-wpi/copy-so-ko-files/copy-so-ko-files
mkdir -p recipes-wpi/copy-so-ko-files/copy-so-ko-files/ffmpeg && \
mkdir -p recipes-wpi/copy-so-ko-files/copy-so-ko-files/opencv && \
mkdir -p recipes-wpi/copy-so-ko-files/copy-so-ko-files/s32v_lib
cd recipes-wpi/copy-so-ko-files/
touch copy-so-ko-files_1.0.bb，並將下列虛線內 recipe 檔案內容，用文字編輯器 (例如 VIM) 新增至 copy-so-ko-files_1.0.bb中，編輯完成後存檔。

cd /sources/meta-alb/recipes-fsl/images/
請用文字編輯器 (例如 VIM) 編輯 fsl-image-auto.bb，並在 IMAGE_INSTALL 區段內新增以下虛線內程式碼：
--------------------------------------------------------------------------------------------------------------------------
copy-so-ko-files \
--------------------------------------------------------------------------------------------------------------------------
編輯完成後存檔。
3. 複製 OpenCV，ffmpeg，kernel module 等 .so & .ko 檔案至 recipe 資料夾：
Copy ffmpeg library:
cp -rv /s32v234_sdk/3rdparty/ffmpeg/linux-arm64/lib/*.so Project>/sources/meta-alb/recipes-wpi/copy-so-ko-files/copy-so-ko-files/ffmpeg/
Copy opencv library:
cp -rv /s32v234_sdk/3rdparty/ocv/cmake-v234ce-gnu-linux/lib/*.so.3.1* Project>/sources/meta-alb/recipes-wpi/copy-so-ko-files/copy-so-ko-files/opencv/
Copy kernel module:
cp -rv /s32v234_sdk/s32v_lib_temp/*.ko /sources/meta-alb/recipes-wpi/copy-so-ko-files/copy-so-ko-files/s32v_lib/
4. 重新編譯：
bitbake fsl-image-auto
確認檔案是否有包進rootfs，可到以下路徑做確認：
cd /build_s32v234evb/tmp/work/s32v234evb-fsl-linux/fsl-image-auto/1.0-r0/rootfs
即可確認完成 S32V Yocto BSP & VSDK 環境建置。
