Other Parts Discussed in Thread: SYSBIOS
TI专家您好：
我在ti-processor-sdk-rtos-j721e-evm-08_06_01_03/vision_apps/apps/dl_demos下新建文件夹 my_disp_img,在my_disp_img目录下有四个文件如下：concerto.mak ,app_common.h , main_linux_arm.c main.c
最后我在vision_apps目录下完成编译，并在vision_apps/out/J7/A72/LINUX/relase/下生成了相应的可执行文件：my_disp_img.out，并将文件拷贝到SK-TDA4VM评估板上执行 ./my_disp_img.out 却提示节点核注册失败！！对此我比较疑惑，首先tivxDisplayNode这个核不是贵公司已经封装注册好的吗，我们不能直接从本地加载图片然后调用此显示核在屏幕上显示吗？
若没有在目标端注册的话，那么我在目标端需要怎么操作才能在arm设计端调用此tivxDisplayNode节点核呢？
期待您的回复！
best wish

具体的打印日志信息、编译文件、源文件代码如下：
//----------拷贝到评估版上执行 ./my_disp_img.out --------------------------------------------------------------------------/
