Softgun Configuration File

The softgun configuration directory is ˜/.softgun/. There is one configuration file per emulated board. The configuration files have the suffix ".sg". When the emulator is started the name of the configuration file without the suffix is given as command line argument.

Example: Create the directories, select the configuration file for your board and write some precomiled images into the flash: 

# mkdir ~/.softgun
# mkdir ~/my_discimages
# cp softgun/configs/unc90.sg ~/.softgun/
# vi ~/.softgun/unc90.sg
... edit configfile here
# softgun  -l uboot  /cdrom/images/unc90dev/u-boot-unc90dev.bin \
           -l kernel /cdrom/images/unc90dev/uImage-unc90dev \
           -l rootfs /cdrom/images/unc90dev/rootfs-unc90dev.jffs2 \
	   unc90

If no configuration name is given on the commandline softgun uses "defaultboard.sg".

Syntax

The configuration files consists of sections and variable/value pairs. The comment sign is "#" 
[<section name>]
<variable_1>: value_1
<variable_2>: value_2
......
The configuration file has some sections which are present always (global, regions, loader). Additionally there is one section for each emulated chip. The section name is the instance name of the chip.
