Config Block
The Config Block is a special section of the Flash Layout. It basically holds the information used by the Bootloader.
Description of the Config Block Contents
The config block entries are grouped into sections. These sections contain relevant information to control the boot process and basic system properties.
Config Block Sections
- mac (Ethernet MAC Address)
- mult (Clocks Multipliers)
- ip (IP Config)
- boot (Boot Config)
- ser (Serial Port Config)
- loc (Flash Locations (Layout))
- gpio (GPIOs Config)
- hw (HW Version)
- dbg (Debug Config)
- ss (SplashScreen Config
- pex (Processor Extensions)
- karg (Kernel Arguments)
- part (Flash partition layout)
- mem (Reserve memory for display and M4 core)
!!WARNING!!: It is possible to modify the Configblock in a way that the module doesn't start any more, be care full if you modify it.
Changing the ConfigBlock Contents
There are four options to change the contents of the config block:
Bootloader Command Line
Use the Command Prompt of the Bootloader to access the Config Block data or the Config Block Editor.
The following bootloader commands are used to change config block settings
setconfig <section>.<param> <value>
saveconfig <section>
clearconfig <section>
(set, save and clear are short forms of the commands described above)
Config Block Editor (Interactive Mode)
The Config Block Editor is a WinCE application developed by Toradex. It can be used to edit settings stored in the Config Block.
You can find the Config Block Editor in the Colibri Software section.
Config Block Editor (Batch Mode)
Beginning with revision 1.1, the config block editor has a feature to change config block settings from within Windows CE.
Usage:
configblockeditor.exe <batchfilename>
e.g. configblockeditor.exe \pathtofile\settings.txt
The batchfile contains a list of commands, following a simple syntax, which is very similar to the bootloader command line:
setconfig <group>.<param> <value>
saveconfig <group>
clearconfig <group>
# or ; at line start are treated as comments
