Hi:
The BSP that comes with the i.MX31 ADS board does include the source code and the rights to use it. Here is part of the licence agreement :
“The Board Support Package consists of the following source code components which are based on Microsoft’s Windows CE Platform Builder code (1) OEM abstraction layer, (2) boot loader, (3) device drivers and (4) documentation (“Underlying Software”) as well as enhancements made by Freescale, in source code format, to the Underlying Software in order to support certain Freescale microprocessors (“Freescale Modifications”).”
“Freescale grants to you, free of charge, the non-exclusive, non-transferable right, exclusively for activities which support products which incorporate Freescale microprocessors (1) to use the Freescale Modifications internally and (2) to reproduce the Freescale Modifications (3) to prepare derivative works of the Freescale Modifications, (4) to distribute and sublicense to others the right to use the object code version of the Freescale Modifications and derivative works thereof, solely in conjunction with devices that contain Freescale microprocessors.”
As for the RealView ICE unit, it is not really necessary if you just need to load the bootloader. You can get the job done by downloading the "MCIMX31ADSE_HABTOOLKIT V1_2" and following the included instructions.
You can download this tool using the following link :
I hope this helps !
