What are the types of issues are involved in integrating the VxWorks driver in a typical system?
A. Because VxWorks runs on so many types of embedded and real-time systems and CPU types, some minor board and BSP specific differences requiring integration should be expected. Specifically, the gigabit controller and driver require the following system resources be mapped properly in order to function: 1. PCI Configuration of memory mapped i/o address used to access controller registers as a PCI target from the CPU and mapping to local bus address. 2. PCI configuration of interrupt and mapping to local CPU interrupt vector. 3. Mapping of local SDRAM buffers and buffer descriptor addresses to PCI bus addressees used by the controller for bus-master DMA operations. In most cases, all that is needed is to re-compile the driver — the default settings are appropriate and the driver is written to accommodate these minor variations in BSP implementations.
