Hi @bighero77,

Thank you for contacting NXP Support.

According to the README file, the application required for your use case is ethosu_apps_rpmsg, not ethosu_apps.

README extract:

4. Test process
---------------
4.1 Example ethosu_apps_rpmsg is built as .out or .elf and installed in rootfs. In Linux command line,
    user can run the following command to do inference for the model.
    #./inference_runner -d /dev/ethosu0 -n mobilenet_v1_1.0_224_pb_int8_vela.tflite -i stopwatch.bmp -l labels.txt -o output_data_detection -t 1080000000

    When the examples runs, the log and inference result would be seen on the terminal as below.

    For other demos, such as face recognition, please refer to the user manual.

4.2 Example ethous_apps is built as .bin. In U-Boot prompt, user can run the following command to do
    inference for the conv2d op model.
    u-boot=> tftp 0x80000000 ethosu_apps.bin;cp.b 0x80000000 0x201e0000 0x20000;bootaux 0x201e0000 0

    When the example runs, the log and inference result would be seen on the terminal as below.

    Initialize Arm Ethos-U
    Inference status: success

Based on the documentation, if your goal is to run inference from Linux using /dev/ethosu0, then ethosu_apps_rpmsg is the correct application to use.
