Boot the board

  • (Optional)if use SD Card boot,need into the socket on the board.
  • (Optional) Use the USB to TTL serial cable to setup a connection between PC and ArmSoM-w3 board.
  • Power on ArmSoM by adapter with type C port or PoE or DC power
  • ArmSoM-w3 will boot with the green power LED on. And after a while, another blue LED starts blinking,red led user control

interface use

Access from the Host PC/Laptop

Option 1: HDMI monitor and Mouse

You can open the terminal on the HDMI display and enter commands on the keyboard.

Option 2: Serial console

See Serial Console

Option 3: ADB

Using the burning tool provided by RK, you can not see the line "Found an MSC device" at the bottom. Connect the computer to the development board using a USB-typeC cable. On the Windows page, use the combined key of "Windows+R" to open the command terminal and type adb shell to see "root@linaro-alip:/#".

LED

On ArmSoM-W3 three-color LED is configured as LED class device. When the blue LED is not active a green LED will show to indicate the board has power. You can control the behavior mode of the blue LED by writing to /sys/class/leds/blue:status/trigger. By default only root users can write to the device. The default mode of the blue LED is heartbeat. 

linaro@linaro-alip:/home/linaro# sudo su // linaro password
root@linaro-alip:/home/linaro# echo timer > /sys/class/leds/blue:status/trigger
root@linaro-alip:/home/linaro# echo activity > /sys/class/leds/blue:status/trigger

You can use cat on the trigger property to list all the available LED modes. The value in brackets is the currently active mode. 

root@linaro-alip:/home/linaro# cat /sys/class/leds/blue:status/trigger
none rfkill-any rfkill-none kbd-scrolllock kbd-numlock kbd-capslock kbd-kanalock kbd-shiftlock kbd-altgrlock kbd-ctrllock kbd-altlock kbd-shiftllock kbd-shiftrlock kbd-ctrlllock kbd-ctrlrlock tcpm-source-psy-4-0022-online mmc2 mmc1 timer oneshot disk-activity disk-read disk-write ide-disk mtd nand-disk heartbeat backlight gpio cpu cpu0 cpu1 cpu2 cpu3 cpu4 cpu5 cpu6 cpu7 mmc0 [activity] default-on transient flash torch panic netdev rfkill0

In the None mode, writing to /sys/class/leds/blue:status/brightness can manually control the status of the blue LED. 

root@linaro-alip:/home/linaro# echo none > /sys/class/leds/blue:status/trigger
root@linaro-alip:/home/linaro# echo 1 > /sys/class/leds/blue:status/brightness
root@linaro-alip:/home/linaro# echo 0 > /sys/class/leds/blue:status/brightness

red light is the same, class device /sys/class/leds/red:status/trigger

RTC Device

ArmSoM-w3 is equipped with one RTC IC hym8563

Firstly, plug in RTC battery to give power to RTC IC. Please note that we should keep the RTC battery in the RTC connector.

Secondly,Check whether the driver is successfully loaded. 

root@linaro-alip:~# dmesg | grep rtc
[    3.149263] rtc-hym8563 6-0051: rtc information is valid
[    3.154624] rtc-hym8563 6-0051: registered as rtc0
[    3.155646] rtc-hym8563 6-0051: setting system clock to 2021-01-01T12:00:05 UTC (1609502405)

Finally, check whether you can view and set the time. 

root@linaro-alip:~# hwclock -r
2022-08-07 13:38:24.370866+00:00
root@linaro-alip:~# date

root@linaro-alip:~# hwclock -w

Ethernet

ArmSoM-w3 is configured with one 2.5G Ethernet interface. You can connect ArmSoM-w3 to the network using a network cable (one end is connected to an external network port or a route). The ArmSoM-w3 automatically configures the network for your Internet access.

Check that the Ethernet is working by using the ifconfig command, which displays network card eth0 or enP4p65s0, along with the Ethernet IP address. In addition, you can use the ping tool to test network connectivity. 

ifconfig

ping www.google.com

If the network cable is connected, no IP address is assigned to the node. 

dhclient eth0
or
dhclient enP4p65s0

WiFi/BT

ArmSoM-w3 doesn't come with on board WiFi/BT. Currently the following WiFi Cards are tested and supported by the ArmSoM-w3.

1. RTL8852BE

2. AP6256

To test the WIFI performance, we need to follow the steps: 

# 1. Switch to super user mode
root@linaro-alip:/# sudo su
# 2. Open the WIFI
root@linaro-alip:/# nmcli r wifi on
# 3. Scan WIFI
root@linaro-alip:/# nmcli dev wifi
# 4. Connect to WIFI network
root@linaro-alip:/# nmcli dev wifi connect "wifi_name" password "wifi_password"

HDMI RX

The ArmSoM-w3 uses an hdmi_in port built into the rk3588 chip,You can use the v4l2 command to test the hdmi in interface.

View all video nodes

ls /dev/video*

Look for the rk hdmirx device

Run the v4l2-ctl -d command to specify the vidoe node. Run the -D command to view the node information. Check the rk_hdmirx device using the Driver name.

NPU usage

‎

Prepare tools

1. Use the Ubuntu18.04 / Ubuntu20.04 operating system (OS).

2. An W3-PRO board

Preparation procedure

First make sure you have docker installed on your Ubuntu system,If not, refer to the Internet installation tutorial

We provide the source code and the docker image of the installed environment:docker image

Create a rknpu folder on the PC server and copy the firmware to the folder 

rknpu/rknn-toolkit2-1.4.0/docker$ ls
md5sum.txt  rknn-toolkit2-1.4.0-cp36-docker.tar.gz  rknn-toolkit2-1.4.0-cp38-docker.tar.gz

Run the following command to run the docker image. After the Docker image is run, the bash environment of the image is displayed 

docker run -t -i --privileged -v /dev/bus/usb:/dev/bus/usb rknn-toolkit2:1.4.0-cp38 /bin/bash

Map examples code into a Docker environment by attaching "-v <host src folder>:<image dst folder>"Parameters, such as: 

docker run -t -i --privileged -v /dev/bus/usb:/dev/bus/usb -v /your/rknn-toolkit2-1.x.x/examples:/examples rknn-toolkit2:1.x.x /bin/bash

The code is synchronized after mapping

The rknn service needs to run on the development board

BOARD ARCH corresponds to the aarch64 directory on 64-bit Linux systems and to the armhf directory on 32-bit systems 

1. adb push all files in Linux/rknn server/${B0ARD_ ARCH}/usr/bin/ to /usr/bin
2. adb push Linux/librknn api/${BOARD ARCH}/ librknrnt. so to /usr/1ib
3. Access the serial port terminal of the board and run the following command
 chmod +x /usr/bin/rknn server
 chmod +X /usr/bin/start_ rknn.sh
 chmod +X /usr/bin/restart rknn.sh
 restart_ rknn. sh

run program

Execute adb devices in the docker image first, remembering the adb ID number

Go to /examples/onnx/yolov5 and change test.py 

ret = rknn.init_runtime(target='rk3588', device_id=DEVICE_ID, perf_debug=True,eval_mem=True)
outputs = rknn.inference(inputs=[img])
ret = rknn.eval_perf(inputs=[img], is_print=True)
cv2.imwrite("result.jpg", img_1)

The above four functions are not added

Run python3 test.py
