1. Execute getevent -l | grep MSC_SCAN in the serial port or adb shell, then press the corresponding button on the remote control to obtain the device ID and scancode.
M4b custom ir 1.jpg
The MSC_SCAN data is 32 bits.
Bits [31:24] represent the key press status, where 0 indicates release, and 1 indicates press.
Bits [23:8] represent the device ID. Use this ID to generate a keylayout file named customer_ir_xxxx.kl. For example, in this case, it would be customer_ir_fe01.kl.
Bits [7:0] represent the scancode.
2. Based on the results of step one, create a new file named customer_ir_xxxx.kl with the following content:
M4b custom ir 2.jpg
Map the scancodes in the second column to Android keycodes.
3. Use the adb command to push customer_ir_xxxx.kl to the system.
 $ adb root
 $ adb remount
 $ adb push customer_ir_xxxx.kl  /system/usr/keylayout/
 $ adb reboot
For source code porting, put the customer_ir_xxxx.kl to vendor/w/common/hardware/input/multi_ir/keylayout/ directory and build the source code.

1. Boot logo
Rename the logo file to bootlogo.bmp and put it in longan/device/config/chips/h618/boot-resource/boot-resource/ directory.

  nmcli connection up [NAME] # Activate a connection
  nmcli connection delete [SSID] #Delete a configuration and no longer save information and automatically connect
  nmcli radio wifi off # Turn off wifi
  nmcli radio wifi on # Turn on wifi

Set static IP, DNS

1. To set a static IP, you need to maintain the connection first. If you want to set an Ethernet static IP, you must first maintain the Ethernet connection; if you want to set a wireless network static IP, you must first maintain a connection to a WIFI.
2. If the upper-level router has assigned the IP address you want to set to other devices, please change it to an idle IP, or ask other devices to give up the IP.
3. Use the nmcli connection show command to display all connections, for example:
  pi@bpi-m4berry:~$ nmcli connection show
  TP-LINK_5G_7747 e4a49726-adf1-44d7-a621-0e3af96cc390 wifi wlx2cc3e6acd5d7
  Wired connection 1 612eda94-55dc-3c85-b05e-f16c41775b4e ethernet --
4. Use the nmcli connection show [NAME] command to display all the properties of a specific connection, such as:
  nmcli connection show TP-LINK_5G_7747 #If you want to see Ethernet, change to Wired connection 1
  #Only list three common items
  ipv4.dns: #The default is the gateway address
  ipv4.addresses: #The default is the IP address assigned by the router DHCP
  ipv4.gateway: #Gateway address, the default is the IP address of the router
5.Set static IP:
  nmcli connection modify TP-LINK_5G_7747 ipv4.addresses
6.Set DNS:
  nmcli connection modify TP-LINK_5G_7747 ipv4.dns #Google DNS
8. After restarting, check whether the modification is successful:
  nmcli connection show TP-LINK_5G_7747

Transfer files


scp (secure copy) command in Linux system is used to copy file(s) between servers in a secure way.

The SCP command or secure copy allows the secure transferring of files between the local host and the remote host or between two remote hosts.

It uses the same authentication and security as it is used in the Secure Shell (SSH) protocol.

You can copy files from a Windows terminal to a Linux system on the same LAN. Just make sure the Open SSH client is turned on and can be viewed in Settings > Applications > Optional Features.

If you want to copy files from Windows systems to Linux systems, you also need to enable the Open SSH server.

Bpi m4 berry mobaxterm 6.jpg

The scp command format is:

scp [optionals] file_source file_target
1.[optionals] is an optional parameter, such as -r, which can be used to copy the entire directory recursively.
2.file_source The file or directory to be copied.
3.file_target will copy the past path and rename it if a specific file name is entered at the end.

Take copying local files from a Windows system to a Linux system as an example. In the Windows terminal, enter:

PS D:\temp\temp_4> scp ".\hello.txt" [email protected]:"/home/pi/Downloads/"

You can also copy files in the Linux system to the local computer in the Windows terminal:

PS D:\temp\temp_4> scp [email protected]:"/home/pi/Downloads/hello.txt" "D:\temp\temp_4"
Where [email protected] is the user name in the Linux system and the IP address of the BPI-M4 Berry in the LAN.
Where :"/home/pi/Downloads/hello.txt" is the file path in the Linux system.
Where "D:\temp\temp_4" is the path in Windows system.

scp reference document


Files can be managed through a graphical interface using mobaxterm or other similar software.

mobaxterm download
mobaxterm-linux preview version

As shown in the figure below, after establishing an SSH connection in mobaxterm, a file management window will appear on the left side of the interface, which supports copying and pasting by dragging and dropping files.
