I want to display the superimposed picture in C7x Kernel Application, so I created disp_node and disp_graph with reference to dl_demos, and before creating disp_node and disp_graph, I executed tivxHwaLoadKernels(context); this function, but in vxVerifyGraph(disp_graph) Times The following error:
0.1072s: VX_ZONE_ERROR:[tivxTargetKernelInstanceAlloc:114] kernel com.ti.hwa.display has not been registered on this CPU

The source program is shown in the following figure: the tivxHwaLoadKernels(context) function is executed, and disp_node and disp_graph are created:
