3.3. Run XVDPU application¶
The smart-mipi-app application is targeted to run with Single-MIPI(Leopard IMX274 MIPI) or Quad-MIPI(Avnet Multi-Camera MIPI) sensor as input source, and HDMI as output sink. The application supports 4 models - yolov3, refinedet, densebox, ssd.
Follow these steps to boot the board into Linux
- Ensure all steps under the section Board Setup are verified. Make connections based on the input source and output sink selected.
- Insert the prepared micro SD card into the Versal SD card slot (refer to the image in Board Setup)
- Have the UART0 terminal emulator tab connected.
- Turn ON power switch SW13.
- On Versal UART0 terminal, you would see the Versal device booting from the micro SD card starting with the message “Xilinx Versal Platform Loader and Manager”
- In about 60 seconds boot is complete and will stop at the Linux prompt root@xilinx-vck190-2021_1
- For ES1 VCK190 board, please run command /etc/init.d/aie_workaround4es1.sh in linux shell, production VCK190 board can skip this step
- Use command line options provided below to run the smart-mipi-app application
3.3.1. Examples for quad-mipi sensor¶
Run 4 channel mipi camera with 3840x2160 resolution monitor
smart-mipi-app
Run 4 channel mipi camera with 1920x1080 resolution monitor
smart-mipi-app -W 1920 -H 1080
Run 4 channel mipi camera with specified AI model
smart-mipi-app --t1=yolov3 --t2=refinedet --t3=facedetect --t4=ssd
Run 4 channel mipi camera with specified media device, the default is “/dev/media1”
smart-mipi-app -m 2
3.3.2. Examples for single-mipi sensor¶
Run 1 channel mipi camera with 3840x2160 resolution monitor
smart-mipi-app -s
Run 1 channel mipi camera with 1920x1080 resolution monitor
smart-mipi-app -s -W 1920 -H 1080
Run 1 channel mipi camera with specified AI model
smart-mipi-app -s -t yolov3
Run 1 channel mipi camera with specified media device, the default is “/dev/media1”
smart-mipi-app -s -m 2
Note: Currently, Only yolov3, densebox, refinedet, ssd models are supported by this application.
3.3.3. Command Options:¶
- The examples show the capability of the smart-mipi-app for specific configurations. User can get more and detailed application options as following by invoking
smart-mipi-app -h
Usage:
smart-mipi-app [OPTION?] - Application for detction on VCK190 board of Xilinx.
Examples for 4 mipi camera:
smart-mipi-app
# Run 4 channel mipi camera with 3840x2160 resolution monitor.
smart-mipi-app -W 1920 -H 1080
# Change to 1920x1080 resolution monitor.
smart-mipi-app --t1=yolov3 --t2=refinedet --t3=facedetect --t4=ssd
# Change ai task for each channel
smart-mipi-app -m 2
# Change mipi camera device to /dev/media2.
Examples for single mipi camera:
smart-mipi-app -s
# Run single channel mipi camera with 3840x2160 resolution monitor.
smart-mipi-app -s -W 1920 -H 1080
# Change to 1920x1080 resolution monitor.
smart-mipi-app -s -t ssd
# Change ai task from yolov3 to ssd
smart-mipi-app -s -m 2
# Change mipi camera device to /dev/media2.
