ethosu_apps#
Overview#
The example ethosu_apps accomplishes the inference for conv2d op model. The inference engine is TensorFlow Lite Micro.
Toolchains supported#
IAR Embedded Workbench for ARM
ArmGCC - GNU Tools ARM Embedded
Supported Boards#
MCIMX93W-EVK
Hardware requirements
Micro USB cable
MIMX93W-EVK board
J-Link Debug Probe
5V power supply
Personal Computer
Board settings
No special settings are required.
Please note this application can’t support running with Linux BSP!
Prepare the Demo
Connect 5V power supply and J-Link Debug Probe to the board, switch SW1 to power on the board.
Connect a micro USB cable between the host PC and the J6 USB port on the target board.
Open a serial terminal with the following settings:
115200 baud rate
8 data bits
No parity
One stop bit
No flow control
Download the program to the target board.
Either press the reset button on your board or launch the debugger in your IDE to begin running the example.
Running the demo
This example is built as .bin. In the U-Boot prompt, users can run the following command to perform 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 appear on the terminal as shown below:
Initialize Arm Ethos-U
Inference status: success
