Working with pre-flashed software

The serial connection information can be configured in the 'configure minicom' submenu

and then 'Serial port setup'. After that, the configuration must be saved using the 'Save

setup as' option. The serial device name to be entered must match the one used for the link

to the SPEAr evaluation board. For example, the first serial port on Linux PC is named

/dev/ttyS0.

Select the serial speed as 115200 bps with 8 bit, no parity and 1 stop bit (115200 8N1) and

disable both hardware and software flow control.

Figure 3.

Minicom serial port configuration (Linux PC)

To save a new default configuration which is automatically used by minicom, select "Save

setup as dfl".

Alternatively, to create a new configuration file select "Save setup as..". In order to use it,

you have to specify the configuration file name in the command line when invoking minicom.

Please note that by default minicom tries to initialize a "modem" connected to the specific

interface you have chosen. To skip this step you can invoke minicom with the -o option as

follows:

$ minicom -o

Overview of Flash contents and structure

On all evaluation boards, the default software is only pre-stored into serial NOR Flash. The

use of other memory types available on some evaluation boards (NAND, parallel NOR)

requires the installation and usage of the STLinux distribution, as described in Chapter 3:

The STLinux distribution.

This subsection only provides an overview of the Flash contents and structuring. Details on

this subject (like offsets and sizes for each partition, as well as differences between serial
