J14 M.2 KEY E Slot is used for connect Wlan&BT adapter, default image support RTL8822CE(PCIE+USB) and RTL8822CS(SDIO+UART).

Connect WiFi

Command line connection

1.Open WiFi:

sudo nmcli r wifi on

2.List wifi list:

sudo nmcli dev wifi list

3.Connect to wifi

SSID is BPI, password is bananapi, using the wlan0 interface as an example.

sudo nmcli dev wifi connect BPI password bananapi ifname wlan0

Command line graphical connection

Enter graphics configuration

sudo nmtui

Move the keyboard arrow keys to Active a connection and press Enter to enter wifi settings

Move the arrow keys to the wifi you want to connect to and press Enter

If you are connecting to an unconnected hotspot with a password, you will enter the password input interface.

If you want to disconnect from wifi, press the Enter key when connected to disconnect.

Desktop connection

Open WiFi, select the one you want to connect to, click and enter the password.

Static network

nmtui

Set the ip address before the static address

sudo ifconfig

enP4p65s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
        inet 192.168.10.100 netmask 255.255.255.0 broadcast 192.168.10.255
        ether 92:be:6d:d5:e7:b4 txqueuelen 1000 (Ethernet)
        RX packets 23758 bytes 1774543 (1.6 MiB)
        RX errors 0 dropped 80 overruns 0 frame 0
        TX packets 67013 bytes 3879463 (3.6 MiB)
        TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
        device interrupt 155

If you want to successfully set a static address, you need to pay attention to whether the IP address you want to set is occupied by other devices. You can use ping to set the static address. If there is data returned, it proves that the IP address is occupied by other devices.

The following are detailed steps

1.Enter graphics configuration

nmtui

Move the keyboard arrow keys to Edit a connection and press Enter to enter the wifi settings.

2.Select the network you want to edit, here we take eth0 as an example

Enter to see the default configuration of the network

3.Need to set IPV4 CONFIGURATION to Manual

4.Then move the cursor to show and press enter to enter detailed configuration

Here we take the IP address 192.168.10.13 and the gateway 192.168.10.1 as an example.

NOTE:The IP address and gateway need to be configured according to your actual network conditions. If you copy the configuration here, there is a high chance that your product will not be able to connect to the Internet. Junior developers recommend changing the static IP to a dynamically obtained IP.

How to obtain the gateway

1.Set the network to automatically obtain IP

2. After successfully obtaining the IP, use the command

  route

result

 root@w3:/home/armsom# route
 Kernel IP routing table
 Destination Gateway Genmask Flags Metric Ref Use Iface
 default 192.168.10.1 0.0.0.0 UG 100 0 0 enP4p65s0
 192.168.10.0 0.0.0.0 255.255.255.0 U 100 0 0 enP4p65s0

3.Gateway is our gateway, use the following command

 route-n

result

 root@lubancat:~# route -n
 Kernel IP routing table
 Destination Gateway Genmask Flags Metric Ref Use Iface
 default 192.168.10.1 0.0.0.0 UG 100 0 0 enP4p65s0
 192.168.10.0 0.0.0.0 255.255.255.0 U 100 0 0 enP4p65s0

You can see our gateway address ---- 192.168.10.1

192.168.10.13/24 where /24 represents the mask 255.255.255.0,

DNS servers Nationwide DNS–>114.114.114.114 Global DNS–>8.8.8.8

Search domain can inherit DNS servers settings. Multiple DNS servers and search domains can be set.

After setting up, you can move to the back and click OK to complete the setting.

After completing the settings, you need to activate the settings for the network to take effect. Click Activate a connection to enter the connection, press enter once to cancel the connection, and press enter again to reconnect.

The IP after the re -connection becomes the IP we set up

 root@w3:/home/armsom# ip addr
    lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
     link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
     inet 127.0.0.1/8 scope host lo
        valid_lft forever preferred_lft forever
    enP4p65s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
     link/ether 92:be:6d:d5:e7:b4 brd ff:ff:ff:ff:ff:ff permaddr be:87:f6:b4:e5:ad
     inet 192.168.10.13/24 brd 192.168.10.255 scope global noprefixroute enP4p65s0
        valid_lft forever preferred_lft forever
    wlP2p33s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000
     link/ether 2c:05:47:8e:4a:6c brd ff:ff:ff:ff:ff:ff
    wlan1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000
     link/ether 2e:05:47:8e:4a:6c brd ff:ff:ff:ff:ff:ff

We can also use ping baidu.com to check if we have successfully connected to the external network

 root@w3: $ ping baidu .com
 PING baidu.com (110.242.68.66) 56( 84) bvtes of data.
 64 bytes from 110.242.68.66 (110.242.68.66): icmp seg=1 ttl=50 time=41.9 ms
 64 bytes from 110.242.68.66 (110.242.68.66): icmp seg=2 ttl=50 time=54.2 ms
 64 bytes from 110.242.68.66 (110.242.68.66): icmp seg=3 ttl=50 time=45.8 ms

nmcli

Taking enP4p65s0 as an example, this step is similar to editing the network in nmtui, except that it changes from a graphical interface to a command line operation, with various names in the command line. This is only a partial introduction, and those interested can explore it on their own.

1.First, list the configuration of the connection. eth0 is currently connected to Wired connection 1

 root@w3:/home/armsom# nmcli c s
 NAME                UUID                                  TYPE      DEVICE
 Wired connection 1  e01f934d-7fae-344f-90bf-e2483db3f3e5  ethernet  enP4p65s0
 armsom                d3d9a6ff-9c9c-44f8-a366-6a69af1edd1a  wifi      --
 armsom 1              7867c3af-dca2-4e9a-9721-a20f7a0e1b46  wifi      --

2.Then modify Wired connection 1

Static IP settings

 sudo nmcli c modify 'Wired connection 1'
 
 sudo nmcli c m 'Wired connection 1' ipv4.address 192.168.10.13/24
 sudo nmcli c m 'Wired connection 1' ipv4.method manual
 sudo nmcli c m 'Wired connection 1' ipv4.gateway 192.168.10.1
 sudo nmcli c m 'Wired connection 1' ipv4.dns 8.8.8.8 
 sudo nmcli c m 'Wired connection 1' +ipv4.dns 114.114.114.114 
 sudo nmcli c m 'Wired connection 1' ipv6.method disabled
 sudo nmcli c m 'Wired connection 1' connection.autoconnect yes

Note that IPv4.Address must be modified first before you can modify ipv4.Method!

3.Activate configuration

 sudo nmcli c up ifname eth0

4.After configuration, the IP changed

 root@w3:~$ ip addr
   lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
     link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
     inet 127.0.0.1/8 scope host lo
        valid_lft forever preferred_lft forever
   enP4p65s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
     link/ether 92:be:6d:d5:e7:b4 brd ff:ff:ff:ff:ff:ff permaddr be:87:f6:b4:e5:ad
     inet 192.168.10.14/24 brd 192.168.10.255 scope global noprefixroute enP4p65s0
        valid_lft forever preferred_lft forever
   wlP2p33s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000
     link/ether 2c:05:47:8e:4a:6c brd ff:ff:ff:ff:ff:ff
   wlan1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000
     link/ether 2e:05:47:8e:4a:6c brd ff:ff:ff:ff:ff:ff

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

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.

DEMO video: https://www.youtube.com/watch?v=y7mYxn3rq0U

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

LED

On BPI-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

BPI-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

Overlays

The device tree Overlays make it possible to support multiple hardware configurations with a single kernel, without the need to explicitly load or mask kernel modules.

Ubuntu 22.04 Mirror Enable Overlay

The path for storing the overlay file of Ubuntu 22.04 image on the board side is:/boot/firmware/dtbs/rockchip/overlay/*.dtbo

Find the keyword "overlays=" in the /boot/firmware/ubuntuEnv.txt file. The following is an example of using two overlay layers for BPI-W3.

 overlays=bananapi-w3-camera-imx415-4k bananapi-w3-display-mipi-dsi

After editing, restart the device to change the overlay settings.

Armbian Mirror Enable Overlay

The path for storing the overlay file of Armbian image on the board side is:/boot/dtbs/rockchip/overlay/*.dtbo

Find the keyword "overlays=" in the /boot/armbianEnv.txt file. The following is an example of using two overlay layers for BPI-W3.

 overlays=bananapi-w3-camera-imx415-4k bananapi-w3-display-mipi-dsi

After editing, restart the device to change the overlay settings.

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

-===How to burn image to SD card===
+The rknn service needs to run on the development board
-  A. Note: burn image to SD card on linux computer
-.You could download latest image from our forum
+BOARD ARCH corresponds to the aarch64 directory on 64-bit Linux systems and to the armhf directory on 32-bit systems
-    * Here is the example image link:
+. adb push all files in Linux/rknn server/${B0ARD_ ARCH}/usr/bin/ to /usr/bin
-.Install bpi-tools on your Ubuntu. If you can't access this URL or any other problems, please go to [https://github.com/BPI-SINOVOIP/bpi-tools bpi-tools repo] and install this tools manually.
+. adb push Linux/librknn api/${BOARD ARCH}/ librknrnt. so to /usr/1ib
-    * apt-get install pv
+. Access the serial port terminal of the board and run the following command
-    * curl -sL https://github.com/BPI-SINOVOIP/bpi-tools/raw/master/bpi-tools | sudo -E bash
+ chmod +x /usr/bin/rknn server
+ chmod +X /usr/bin/start_ rknn.sh
-.After you download the image, insert your TF card into your Ubuntu
+ chmod +X /usr/bin/restart rknn.sh
-    * Execute "bpi-copy xxx.img /dev/sdx" to install image on your TF card
+ restart_ rknn. sh
-.After step 3, then you can insert your TF card into R3, and press power button to setup R3
+run program
-  B. Note: burn image to SD card on windows computer
-. Download the tools from the website:   https://sourceforge.net/projects/win32diskimager/
+Execute adb devices in the docker image first, remembering the adb ID number
-. Install the tools into Windows computer.
-. flash image into SD card.
+Go to /examples/onnx/yolov5 and change test.py
-  C. Change Boot Jumper to boot from SD, Enable SD Card Device.
+ ret = rknn.init_runtime(target='rk3588', device_id=DEVICE_ID, perf_debug=True,eval_mem=True)
-    [[Image:BPI-R3-Jumper-ALL-High.png|320px]]
+ outputs = rknn.inference(inputs=[img])
+  ret = rknn.eval_perf(inputs=[img], is_print=True)
+ cv2.imwrite("result.jpg", img_1)
-====How to burn image to onboard eMMC====
+The above four functions are not added
-  Note: because SD card and EMMC device share one SOC's interface, you need flash one SD image firstly, then R3 boot from SD card, then flash nand image into Nand, then change boot strap to boot from nand,  you need flash EMMC image into EMMC. Finally you change bootstrap to boot from EMMC.
-  Before burning image to eMMC, please prepare a SD card with flashed bootable image and a USB disk. Let's take OpenWrt image (mtk-bpi-r3-SD-WAN1-SFP1-20220619-single-image.img, mtk-bpi-r3-NAND-WAN1-SFP1-20220619-single-image.bin, bl2_emmc.img, mtk-bpi-r3-EMMC-WAN1-SFP1-20220619-single-image.img) for example, the steps are below:
+Run python3 test.py
-. Insert the flashed SD card and power on to start the board.(the image "mtk-bpi-r3-SD-WAN1-SFP1-20220619-single-image.img" on the SD card can be OpenWrt or other linux OS like ubuntu...)
+==LED==
-. Copy Nand bootable and EMMC boot OpenWrt image(mtk-bpi-r3-NAND-WAN1-SFP1-20220619-single-image.bin, bl2_emmc.img, mtk-bpi-r3-EMMC-WAN1-SFP1-20220619-single-image.img) to USB disk, if the image is compressed please uncompress it before copying to USB disk.
+On BPI-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.
-. Plug in USB disk to the board, and mount the USB to /mnt or other directory as follows: (you can skip mounting if it is mounted automatically)
+ linaro@linaro-alip:/home/linaro# sudo su // linaro password
-     * mount -t vfat /dev/sda1 /mnt
+ root@linaro-alip:/home/linaro# echo timer > /sys/class/leds/blue:status/trigger
-     * change your directory to the mounting point, here is : cd /mnt
+ root@linaro-alip:/home/linaro# echo activity > /sys/class/leds/blue:status/trigger
-. Execute following command to enable and copy image to nand flash:
+You can use cat on the trigger property to list all the available LED modes. The value in brackets is the currently active mode.
-     * mtd erase /dev/mtd0
-     * dd if=mtk-bpi-r3-NAND-WAN1-SFP1-20220619-single-image.bin of=/dev/mtdblock0
-. Shutdown, remove SD card, and change bootstrap to boot from nand flash and change SD/EMMC switch jumper to EMMC, restart the board from Nand Flash.
+ root@linaro-alip:/home/linaro# cat /sys/class/leds/blue:status/trigger

-     [[Image:BPI-R3-Jumper-Flash-EMMC.png|320px]]
-. repeat step 3, mount u-disk to /mnt, Execute following command to enable and copy image to EMMC device:
+In the None mode, writing to /sys/class/leds/blue:status/brightness can manually control the status of the blue LED.
-     * mount -t vfat /dev/sda1 /mnt
-     * echo 0 > /sys/block/mmcblk0boot0/force_ro
-     * dd if=bl2_emmc.img of=/dev/mmcblk0boot0

-     * mmc bootpart enable 1 1 /dev/mmcblk0
-. power off R3 board, remove u-disk driver, change bootstrap to boot from emmc device.

-For example: if you want to change gpio 22 as out highlevel, you need input commands like this：
+. An W3-PRO board
-* echo 433（22+411） > /sys/class/gpio/export
+====Preparation procedure====
-* echo out > /sys/class/gpio/gpio433/direction
+First make sure you have docker installed on your Ubuntu system,If not, refer to the Internet installation tutorial
-* echo 1 > /sys/class/gpio/gpio433/value
-===FAN===
+We provide the source code and the docker image of the installed environment:[https://pan.baidu.com/s/1qm7qPQ-6Cau7kVhf-T-hzg?pwd=1234 docker image]
-[[Image:FAN.png]]
+Create a rknpu folder on the PC server and copy the firmware to the folder
-* R317 for 5V FAN and R318 for 12V FAN.
+ rknpu/rknn-toolkit2-1.4.0/docker$ ls
-* CN23 supports PWM control while CN22 does not support.
+ md5sum.txt  rknn-toolkit2-1.4.0-cp36-docker.tar.gz  rknn-toolkit2-1.4.0-cp38-docker.tar.gz
-====PWM FAN Control====
+Run the following command to run the docker image. After the Docker image is run, the bash environment of the image is displayed
-* echo 0 > /sys/class/pwm/pwmchip0/export
-* echo 10000 > /sys/class/pwm/pwmchip0/pwm0/period
-* echo 5000 >  /sys/class/pwm/pwmchip0/pwm0/duty_cycle
-* echo normal > /sys/class/pwm/pwmchip0/pwm0/polarity
-* echo 1 > /sys/class/pwm/pwmchip0/pwm0/enable
-===miniPCIe slot===
+ docker run -t -i --privileged -v /dev/bus/usb:/dev/bus/usb rknn-toolkit2:1.4.0-cp38 /bin/bash
-currently, miniPCIe slot only support one USB 4G module, example: EC25
-when you insert one EC25 module, you may check it.
-[[Image:BPI-R3-miniPCIe-Slot-EC25.jpg]]
+Map examples code into a Docker environment by attaching "-v <host src folder>:<image dst folder>"Parameters, such as:
-===SFP===
+ 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
-After high and low temperature test, the following modules are suppoted by BPI-R3:
-[[Image:SFP.png]]
+The code is synchronized after mapping
-===4G&5G===
+The rknn service needs to run on the development board
-* BPI-R3 supports 4G LTE EC25.
-* If you want to use 5G on BPI-R3:
-. Insert 5G dongle into USB3.0.
-. Connect RG200U-CN to mini PCIe, connect SoC through USB2.0(speed limited).
-. Make an RG200U-CN LGA adapter board and insert it into M.2 KEY M.
-Note: The availability of 4G/5G depends on the local carrier frequency band.
-===Ap mode on BPI-R3===
+BOARD ARCH corresponds to the aarch64 directory on 64-bit Linux systems and to the armhf directory on 32-bit systems
-* ra0  is MT7986a 2.4G wifi
+. adb push all files in Linux/rknn server/${B0ARD_ ARCH}/usr/bin/ to /usr/bin
-* rax0 is MT7986a 5G wifi
+. adb push Linux/librknn api/${BOARD ARCH}/ librknrnt. so to /usr/1ib
+. 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
-===Wifi & Serial cable===
+====run program====
-* '''If the chip type of serial cable is pl2303, the driver fails to load the firmware apparently and thus the wifi can't work.'''
+Execute adb devices in the docker image first, remembering the adb ID number
-* '''Other types including cp2102,ch340 and FDTI are all available, serial cable vlotage must be 3.3v LVTTL standard.
-'''
-'''UART_TX0 is the Boot Strapping PIN and must be kept low during power-on.'''
-[[Image:Strapping.png|720px]]
+Go to /examples/onnx/yolov5 and change test.py
