UDOO usb debug

Introduction

Udoo features a built in USB to serial interface which is very useful for various reasons: You can use it to connect Udoo via SSH without a network connection, programming the Sam3x (arduino) and access the debug console for troubleshooting purposes.

Connecting via serial will practically result in a shell console, the same as the one you’ll obtain through SSH connection.

Windows

• Download the serial adapter Driver here
• Install the proper version for your Operating system:
  • CP210xVCPInstaller_x86.exe for 32-bit systems
  • CP210xVCPInstaller_x64.exe for 64-bit system
• Download and install Putty
• Open putty and configure it as follows:
  • Connection type “serial”
  • Port: “COM3” (please note that this value may be different, try to use COM4 if COM3 is not working)
  • Speed: “115200”
  • Save it as “Udoo-serial” for future uses.
• Connect the serial port of UDOO (CN6) to your PC using the micro USB cable.
• Power up UDOO
• Click Open
• Done!
• You’re in! You’ll be able to see the startup process and access to the remote shell console on UDOO.

• Install minicom:

sudo apt-get update
sudo apt-get install minicom

• Open Minicom and configure it (only the first time) using the following command:

sudo minicom -sw

• Go to “Serial port setup” and edit as follow:

Serial Device: /dev/ttyUSB0 (type a key)
Hardware Flow Control: No (type f key)
Software Flow Control: No (type g key)

• Press exit and “Save setup as dfl”
• Exit from Minicom
• Let’s give proper access permissions to serial port with:

sudo chmod 666 /dev/ttyUSB0

• Now we can start listening with:

sudo minicom -w

• Power cycle UDOO to see the boot process and connect it to serial console shell

Mac OS X
