Error (DPU Integration Tutorial): Failed to load section from hybrid DPU file.

Hello,

I am following the DPU Integration tutorial for the ZCU102 board with DPU arch B1152.

Running ./resnet50.elf works fine, but ./face_detection.elf gives the error:

[DNNDK] Faild to load section from hybrid DPU file. section:METADATA, hybrid ELF:/media/card/face_detection/face_detection.elf
1- Specified DPU Kernel name "densebox" is right
2- DPU Kernel "densebox" is compiled and linked into "/media/card/face_detection/face_detection.elf" as expected

I am using the face_detection.cc and dpu_densebox.elf found here: https://github.com/Xilinx/Edge-AI-Platform-Tutorials/tree/master/docs/DPU-Integration/reference-files/files/face_detection

Looking at other forum posts.. I tried changing line 398 in face_detection.cc to DPUKernel *kernel = dpuLoadKernel("dpu_densebox") but I got the same error. 

Running ./resnet50 worked fine though, using main.cc and dpu_resnet50_0.elf (B1152_1.4.0). I also see that face_detection.cc has not been recently updated, while the main.cc for resnet50 has been updated recently. 

@terryo Could you please help me check this?

Thanks in advance,

miaoush

Have you tried to use the pre-built version of hte face_detectione.elf? Can you compare the size of your .elf to the one in the pre-built folder?
