Hi @cristiansegattini, you can also try disabling NVMM memory in jetson-inference to see if that helps:
cd /path/to/your/jetson-inference/build
cmake -DENABLE_NVMM=OFF ../
make
sudo make install
Or you can clone/install the nvmm-disabled
branch of jetson-inference instead: https://github.com/dusty-nv/jetson-inference/tree/nvmm-disabled
Please let me know if that helps - thanks. BTW, you can test CSI camera basic functionality by running nvgstcapture-1.0
program.
