BestComm DMA Module (SDMA)
The BestComm DMA module is the only MPC5200 module for which the MPC5200_Quick_Start initialization code uses an
external embedded-side code. As there is a complete BestComm support in the Freescale (formerly Motorola) BSP package,
both the GCT and MPC5200_Quick_Start code re-use this implementation. Also there is a BestComm Graphical Configuration
Tool available for configuring the BestComm DMA tasks, which relies on the BSP code too.
The latest BSP code as well as the standard RTOS DMA images are included in the MPC5200_Quick_Start distribution so there
are no “external resources” needed to implement DMA operations in Quick Start applications. See
Section 9, MPC5200 BSP
for
more details about BSP package.
The GCT support for BestComm DMA module is limited to configuration of the BestComm control registers and the BSP
initialization sequence. There are two pages dedicated to the BestComm module in the GCT. Except other settings, the main
page
(Figure
38) contains a button to run the BestComm Graphical Configuration Tool for the current project. The second page
can be used to define task priorities and to configure a priority control.
