build dla patch error

[Railcalibur]

hello, I followed the readme to deploy yolo on DLA. However, an error occurred when I applied dla patch and builded trtexec.

Env:

Jetson AGX Orin JetPack 5.1.2 CUDA 11.4 TensorRT 8.5.2.2

Install TensorRT on Orin

sudo bash -c 'echo "deb https://repo.download.nvidia.com/jetson/common r35.4 main" >> /etc/apt/sources.list.d/nvidia-l4t-apt-source.list'
sudo bash -c 'echo "deb https://repo.download.nvidia.com/jetson/t234 r35.4 main" >> /etc/apt/sources.list.d/nvidia-l4t-apt-source.list'
sudo apt-get update
sudo apt-get install cuda tensorrt

Step:

git apply trtexec-dla-standalone-trtv8.5.patch

Could you try to find /user -name "*nvdla_compiler.so*"? If it existed, you may modify the Makefile to link the path.

你能尝试一下find /user -name "*nvdla_compiler.so*"吗？如果存在，可以修改Makefile来链接路径。

Thank you for the reply. The .so file was not exist and the issue was resolved after reflashing the device.
