Using Serial Port Debugging on Windows
Putty or SecureCRT software is usually used on Windows. We recommend the free version of MobaXterm. This is a powerful terminal software. We will introduce how to use this software and  the way you use it is also available for other software.

Download MobaXterm:

1. Select session as Serial.
2. Change Serial port to the COM port found in Device Manager.
3. Set Speed (bps) to 115200.
4. Click OK

Serial Port Debugging on Linux
There are several options on Linux

• minicom
• picocom
• kermit

Take minicom for example:
Install minicom sudo apt-get install minicom
See what the serial device file is after connecting the serial cable. The following example is /dev/ttyUSB0: $ ls /dev/ttyUSB* /dev/ttyUSB0

Run:
$ sudo minicom -b 115200 -D /dev/ttyUSB0 Welcome to minicom 2.7 OPTIONS: I18n
Compiled on Jan 1 2014, 17:13:19. Port /dev/ttyUSB0, 15:57:00

Ethernet SSH

• SE5 16-EA4-11 has two Ethernet ports. By default, Ethernet port 0 (near the serial port) is configured with dynamic IP, while Ethernet port 1 (near the HDMI port) is configured with static
• IP 192.168.150.1, subnet mask 255.255.255.0, you can set the PC to 192.168.150.2/24 for initial login.
• Ethernet port 0 is typically assigned an IP address by the router, and the IP address information may not be known in advance. Therefore, it is recommended for users to use Ethernet port 1 for the initial login.
• After the Ethernet port LED blinks normally, open a terminal and use ssh to log in. The port number is 22, and the username and password are both linaro ssh linaro@192.168.150.1
• If the login fails, you can try whether ping the IP address of SE5 16-EA4-11’s Ethernet port 1 by using PC.
• Note : the PC needs to add the same network segment IP, because the IP address of the PC may not be in the same one.
• The following is how to add the same network segment IP on PC (using administrator mode):
• windows 10
• netsh int ipv4 add address “Ethernet” 192.168.150.101 255.255.255.0
• “Ethernet” refers to the network port, 192.168.150.101 is the IP address, and 255.255.255.0 is the subnet mask.
• linux
• ifconfig enp4s0:1 192.168.100.89
• enp4s0 is the name of the network card driver of the PC, and you need to use ifconfig command to check the detail

Remote Desktop X11VNC

x11vnc is a tool that allows administrators to directly connect to the server’s real X desktop via the VNC Viewer.
First, it is necessary to install the X desktop environment on SE5 16-EA4-11，During installation, select Display Manager to lightdm:

After the installation, start the x11vnc service.

After that, users can use $bm1684_ip:0 address on the PC to remotely connect via VNC. Here are the specific steps to use VNC Viewer:

1. First, download VNC Viewer from the official website and select an appropriate one based on your PC system.
2. After installation, open VNC Viewer and skip the login:
3. Enter SE5 16-EA4-11: $bm1684_ip:0 address
4. Enter the user and password linaro
5. Enter the xfce4 desktop successfully:

Device ID

Check device ID
To check the device ID, you can read the serial number of the core board. After reading successfully, a string in json format will be returned

Fan Operation
SE5 16-EA4-11 fan operates at 4 different levels

The higher the fan operating level, the faster the speed. If the current temperature of the processor is below 53℃, the fan is turned off by default. Users can check the current operating temperature of the processor by executing the following command:
cat /sys/class/thermal/thermal_zone1/temp
Additionally, users can manually turn on the fan (write 0-4. 0 is off and 4 is the maximum level.)
sudo -i echo 4 > /sys/class/thermal/cooling_device0/cur_state

HDMI Display Test

• SE5 16-EA4-11 does not come with a Graphics card chip and the processor HDMI output does not use a standard framebuffer driver. As a result, there is no display when the HDMI is connected by default.

If you want to test the HDMI display, you can connect it to the HDMI port and then execute the test-hdmi script.

• linaro@linaro:~$ sudo -i
• root@bm1684:~# test-hdmi
• found (1024, 768) @ 60 fps
• entry [0] = (1024, 768) added

• found (1920, 1080) detailed timing desc

Network IP Configuration

• The SE5 16-EA4-11 comes with Debian 9 as the default operating system. By default, eth0 in the dual Ethernet port configuration obtains IP dynamically (that is, DHCP). eth1 is 192.168.150.1
• Configure eth1 via /etc/network/interfaces.d/eth1 file. This file serves as the only modification to Debian’s original network configuration.

linaro@linaro:~$ cat /etc/network/interfaces.d/eth1 auto eth1
iface eth1 inet static
address 192.168.150.1
netmask 255.255.255.0
dns-nameservers 192.168.150.1

If users delete this file, eth1 will obtain IP dynamically (DHCP), like eth0 . If you wants to set a static IP address for eth0 as well, you can create an eth0 file under the /etc/network/interafces.d folder, which will take effect after restarting.
It is important to note that it is advisable to avoid configuring both network interface cards as the same network segment. Otherwise this could cause issues.

USB Flash Drive and TF Card Mounting

When a U flash drive or TF card is inserted, the storage device will be recognized as /dev/sdb1 or /dev/mmcblkp1, like desktop PC Linux environment.
The file system supports FAT, FAT32, EXT2/3/4, NTFS. SE5 16-EA4-11 does not support automatic mounting, so you need to mount by yourself. After completing data writing, please use sync or umount operation in time. When shutting down, please use the sudo poweroff command to avoid data loss

USB Flash Drive Mounting
Insert the USB flash drive and use dmesg to find out the corresponding sd device: [15460.953423] [5] sdb: sdb1

• Mount USB Flash Drive:

  • create mounting directory

  • mkdir disk

  • mount

  • sudo mount /dev/sdb1 disk

  • Check the files in the U disk

TF card Mounting
TF card mounting is similar to USB flash drive. Use dmesg to find out the corresponding mmcblk device: [16220.776440] [4] mmcblk1: p1

Mount the TF disk:

• create mounting directory mkdir media

• mount

• sudo mount /dev/mmcblk1p1 media

• Check the files in the TF Card ls media

Use RS485/RS232

RS485

• $ sudo kermit
• C-Kermit> set line /dev/ttyUSB0
• C-Kermit> set speed 9600
• C-Kermit> set flow-control none
• C-Kermit> connect

/dev/ttyUSB0 is the device file of the USB-to-serial adapter, which may vary depending on the actual recognition of the PC.

Send data
The device file for RS232 is /dev/ttyS1. Run the following command on the device:

• sudo -s
• stty -F /dev/ttyS2 9600 -echo
• echo linaroRS485 test… > /dev/ttyS2

The PC’s serial terminal will then receive the string “linaro RS485 test…”.

Receive data

• First, run the following command on the device:
• sudo -s
• cat /dev/ttyS2

Then, enter the string “linaro RS485 test…” in the PC’s serial terminal, and the device will receive the same string.

RS232

• In addition to RS485, SE5 16-EA4-11 also has an RS232 interface with device name /dev/ttyS1 , supporting full-duplex communication with a default baud rate of 115200.
  Note that RS232 is used for login by default, so users should enter the following command to restore it to normal communication serial port functionality: sudo systemctl disable –now serial-getty@ttyS1.service

• The testing steps are similar to RS485. You just need to pay attention to the device name and baudV rate.

Firmware Upgrade

SE5 16-EA4-11 uses a TF card to upgrade firmware. Users must strictly follow the following steps.

Preparation

• SE5 16-EA4-11
• PC
• USB card reader
• TF card (Class10 or higher is recommended, and choose an 8/16/32 GB capacity according to the firmware)
• Firmware to be upgraded

Upgrade Steps

1. The TF card needs to use MBR partition and to be formatted in FAT32 format;
2. Unzip all files from the firmware (in zip compressed format) onto the TF card;
3. Insert the TF card into the TF card slot of SE5 16-EA4-11 and power on;
4. During the upgrade process, the LED light will flash briefly, indicating that the upgrade is in progress;
5. If the upgrade is successful, the green LED light will flash continuously;
6. If the upgrade fails, all LED lights will turn off.

Note:

• If the TF card exceeds 32GB, it may be unable to format it in FAT32 due to limitations of the Windows system, so it would be better to choose a TF card with a size of 32GB or less.
• The upgrade process may take about six minutes. Please be patient.
