Debug UART
Note
Using the Debug UART is optional.
The Argos3D - P33x features a debug UART, which is the primary debug interface for the boot loader as well as
the Linux kernel.
The Debug UART is available via a micro-USB-connector, with a UART-to-USB converter behind. To be able to
access the serial terminal via the Debug UART, you need an appropriate driver installed in your OS for the FTDI
FT234 device.

Most Linux distributions come with an appropriate driver and create a device node
/dev/ttyUSB...
dynamically.
Additionally, one needs a serial terminal emulator, e.g., Minicom or C-Kermit for Linux, or TeraTerm for Windows
OS. The emulator has to be configured with the following settings:
Baud rate
115200
Data bits
8
Parity
none
Stop bits
1
Flow control none
Table 3-4: Debug UART settings
The Debug UART also allows to log in to the camera’s Linux OS. Please see chapter
3.9 for the default login and
how to change it.
