Debug Port Setting
Connect Type-A end of USB cable to PC and Micro-B end of USB cable to Development Platform’s debug USB Micro-AB connector (J24) as shown below.
Install the driver for Debug USB Port in Host PC/Laptop using the below link.
https://ftdichip.com/drivers/vcp-drivers/
Setup the Debug Terminal parameters:
Baud Rate : 115200, Data bits : 8, Parity : None, Stop Bits : 1, Flow Control : None
- On the command prompt of the Linux host machine, run the following command to determine the port number:
$ ls /dev/ttyUSB* - The smaller number is for Arm® Cortex®-A53 core and the bigger number is for Arm® Cortex ®-M4 core.
Minicom
Use the following commands to install and run the serial communication program (minicom as an example):
- Install Minicom using Ubuntu package manager.
$ sudo apt-get install minicom - Launch Minicom using a console window using the port number determined earlier.
$ sudo minicom -s - Configure Minicom as show in below figure
- Next step is to Power ON the board.

- Download Tera Term. After the download, run the installer and then return to this webpage to continue.
- Launch Tera Term. The first time it launches, it shows the following dialog. Select the serial option. Assuming your board is plugged in, there should be a COM port automatically populated in the list.
- Configure the Serial Port Settings.
Go to Setup –> Serial Port and change the settings as shown below.
- Verify that the connection is open. If connected, Tera Term shows something like below in its title bar.

- Download PuTTY. After the download, run the installer and then return to this webpage to continue.
- Launch PuTTY by either double clicking on the executable file you downloaded or from the Start menu, depending on the type of download you selected.
- Configure in the window that launches. Select the Serial radio button and ether the COM port number that you determined earlier. Also enter the baud rate, 115200
- Click “Open” to open the serial connection. Assuming the board is connected and you entered the correct COM port, the terminal window opens. If the configuration is not correct, puTTY alerts you.
- Next step is to Power ON the board.
Powering ON
Connect the 12V power supply plug to the power connector (J3) of the iG-G50S® i.MX 91 SBC as shown below and switch ON the power supply.
Once power is applied to the SBC, the LEDs in the iG-G50S® i.MX 91 SBC will glow as shown in the image below.
Warning:
- Do not try to connect any other Power Supply other than supplied along with iG-G50S® i.MX 91 SBC
- Contact iWave, if power LEDs are not glowing.
Boot screen
User must go through “Software User Guide” and get familiar with software section of iG-G50S® i.MX 91 SBC SOM Development Platform.
