S/W:

1. BSP 15.0

2. Vision SDK of S32 Design Studio 2.0

Hi Experts,

I'm facing a issue while running isp_ov10640_quad demo.

I follow "../NXP/S32DS_Vision_v2.0/S32DS/s32v234_sdk/demos/README.txt" to setup system variables, then go to "../NXP/S32DS_Vision_v2.0/S32DS/s32v234_sdk/demos/isp/isp_ov10640_quad/build-v234ce-gnu-linux-o/" directory and run "make" command to build the demo.

There is a file "isp_ov10640_quad.elf" generated.

I put the isp_ov10640_quad.elf in SD card and boot up S32V234-EVB2 then run this demo.

However, I got a error meassage as follow:

root@s32v234evb:~# ./isp_ov10640_quad.elf

./isp_ov10640_quad.elf: error while loading shared libraries: libopencv_core.so.3.1: cannot open shared object file: No such file or directory

My question is:

How can I get the libopencv_core.so.3.1? Is this library included in BSP 15.0, Vision SDK of S32 Design Studio or other package provided by NXP?

Best Regards,

Wayne Kuo

Hi Wayne,

It seems that you are missing this shared library on target..

Please go to VisionSDK>>s32v234sdk/3rdparty/ocv/linux-arm64/lib. You can find already compiled libopencv_core.so shared library here. Copy that to s32v234's rootfs>>lib and rename it to libopencv_core.so.3.1. This will solve your problem. You can also create symbolic link with new name.
