7.2. Establish serial debug connection with UDOO
7.2.1. Introduction
This chapter will describe the way to install, configure and access he i.Mx6 Serial
Debug Port.
Obviously, it is possible to use all kind of tool to to access serial. This is just a basic
guide for beginners.
The access to debug serial port is very important on UDOO, since it is a very
compact board but with a very high level of complexity inside. It can be useful for
many operations during setup, control, configuration, debug, troubleshooting…
The serial debug port is used for two different reasons:
● The bootloader and kernel send debug messages via serial port, so that the
user can monitor the low level system states;
● A root console is automatically opened on the serial port, allowing bootloader
configuration and system control.
The number of messages sent via serial port can be very high. For this reason, it is
quite useful to increase scrolling capabilities of the terminal, possibly setting them to
a very high or even unlimited number of lines.
Three programs to access serial ports are suggested, depending on the OS used on
th e host PC.
● Teraterm (Windows)
● Minicom (Linux)
● Serial Tools (Mac)
