VxWorks 6.x Board Support Package

The VxWorks 6.x Board Support Package course provides engineers with a fast, cost-effective way to acquire the knowledge necessary to port VxWorks to customer hardware.

After taking this workshop, participants will be able to do the following:

• Define a BSP development strategy.
• Use a hardware bring-up tool to initialize a board and download code.
• Write and debug BSP initialization code.
• Create a basic boot loader image.
• Use Wind River Workbench tools effectively to accelerateboard bring up.
• Integrate device drivers, including interrupt management, clock support, and timestamps.
• Supply the required BSP routines to complete a BSP that complies with Wind River standards.
• Migrate to a BSP with VxBus support.
• Achieve faster, more reliable program development.
• Package and validate a BSP.

• VxWorks 6.9
• Wind River Workbench 3.3

• Developers planning to port a BSP to a new board on a supported architecture
• Device driver writers
• Application programmers interested in learning what occurs at the hardware level of a VxWorks image
• Senior engineers who will decide on a final production image of their product
