Get started with STM32MP135 based SBC
Remove the SBC from box and place above the ESD free area. Use anti-static pad/mat with proper grounding to place the SBC. Also make sure that, below deliverables are received without any physical damage.
The SBC kit contains:
- STM32MP135 based SBC
- 12V, 2A Power Supply
- Safety guidelines
- UART Debug cable *

Boot Switch Setting
Make sure On-Board Switch (SW2) is set properly as shown below image.
SW1-Boot Selection Switch.
Table 1: Boot Media Switch Settings
Note:- The 4th bit of SW2 should always be high for enabling OTG.
Debug Port Setting
Connect Type A end of TTL-232R-RPI cable to PC and 3pin (100mil) Berg House end of TTL-232R-RPI cable to Debug UART Header (J5) as shown below.
Use one of the terminal application depending on the operating system
of the host machine:
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.
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.
Connect the 12V power supply plug to the power connector (J3) of the iW-RainboW-G54S-STM32MP135 based SBC as shown below and switch ON the power supply.
Once power is applied to the SBC, the LEDs in the iW-RainboW-G54S-STM32MP135 based SBC will glow as shown in the image below.
- Do not try to connect any other Power Supply other than supplied along with iW-RainboW-G54S-STM32MP135 based SBC.
- Contact iWave, if power LEDs are not glowing.
User must go through “Software User Guide” and get familiar with software section of iW-RainboW-G54S-STM32MP135 SBC.
Operating System Support.
Power is applied to the SBC & Once the boot get success, depending upon the supported Operating systems and boot loader on particular delivery, boot messages being prompted in the terminal window as shown below. Press Enter key in terminal and done with test environment setup on particular delivery.
