Colibri Tweak Tool

The Colibri Tweak is a free tool which allows you to adjust a lot of system parameters of the Colibri module.

On the Colibri T20 and Apalis/Colibri T30, only a limited number of features are currently supported.

Main Dialog

Some of the functions are:

  • CPU and Memory Speed
  • Display Settings
  • Memory Bus Settings
  • Flash Layout
  • Read/Set HW registers
  • Change the Colibri's serial number. Do this only if the serial number was lost for some reason!

System Clocks


There is also an additional dialog to enable/disable clocks for the PXA's internal peripherals:


Memory Timings


Screenshot of the Memory Timings dialog.

Flash Layout


On this page you can change the Flash Layout or do backups of flash regions.

We recommend to use the Update Tool Version 3.1 or newer to do backup of the flash regions.

Processor Registers


This dialog is used to directly read and write to physical addresses of the PXA processor.

Display Settings

In this tab you can adjust the settings for the display driver. It is also possible to adjust this settings directly in the Registry but it is more comfortable with the Colibri Tweak.

You can find more information about the corresponding registry settings in the article Display Driver Registry Settings.

To make your changes permanent, you need to save the registry.
