Follow the official NXP documentation, i.MX_Machine_Learning_User’s_Guide.pdf, to run the demo provided in 9.2.3.
1. Copy the required files and compile the model for Ethos-U using the vela tool.
cd /usr/bin/ethosu/examples/
cp ../../tensorflow-lite-2.11.1/examples/labels.txt ./
cp ../../tensorflow-lite-2.11.1/examples/grace_hopper.bmp ./
vela ../../tensorflow-lite-2.11.1/examples/mobilenet_v1_1.0_224_quant.tflite

2. Run the model through the TFLite inference engine using Ethos-U Delegate.
cd /usr/bin/tensorflow-lite-2.11.1/examples/./label_image -m ../../ethosu/examples/output/mobilenet_v1_1.0_224_quant_vela.tflite
--external_delegate_path=/usr/lib/libethosu_delegate.so
