Configure Serial Connection
In a standalone setup, regardless of how the DevKit obtains an IP address, it is essential for the developer to establish a connection via the serial interface. This ensures continuous access to the DevKit, allowing the developer to perform necessary tasks even if the network connection is lost.
Depends on the operating system of the developer’s computer, there are different ways to connect to the DevKit via the serial interface.
On the MLSoC DevKit, Make sure the Operation Mode Switch, Run/Program Switch are set according to the diagram above then power on the DevKit.
Use the included serial cable to connect the DevKit to your computer:
One end connects to the DevKit’s serial port.
On the MLSoC DevKit, ensure the triangle mark on the flat connector aligns with the leftmost pin on the DevKit.
On the Modalix Early Access Kit, ensure the triangle mark on the flat connector aligns with the rightmost pin on the DevKit.
On the Modalix DevKit, use the provided USB-A to USB-C cable to connect to the DevKit’s UART port, as labeled on the enclosure.
The other end connects to the computer’s USB Type-A port, use a USB Hub if necessary.
To connect to the DevKit via a serial terminal on Windows, follow these steps:
Identify the COM Port:
Open Device Manager → Expand Ports (COM & LPT).
Look for an entry like USB Serial Port (COMx).
Install and Open a Serial Terminal:
Use PuTTY or Tera Term.
Set the connection type to Serial.
Enter the correct COM Port (e.g.,
COM3).Set Baud Rate to
115200.
Click Open to start the connection.
Note
Please install or upgrade sima-cli before continuing. This guide is intended for use with the latest sima-cli version.
sima-cli serial
This command will install necessary dependencies on your computer to access serial port. To exit the serial terminal, press Ctrl + A then Ctrl + X.
On some earlier firmware versions, the system may use a different baud rate for the serial console. If you see garbled output in the terminal, it’s likely due to a mismatched baud rate. Try specifying a higher rate:
sima-cli serial -b 921600
Once prompted to log in to the serial port console, use the default username sima and password edgeai.
