explain about BSP in Vxworks

[muruga86]

can any one tell me about significance of Board support package (BSP) in VXworks and why it is so important?

BSP contains all the low level drivers for the specific board it was written for. Your work gets much easier with it because you can start right away with your application level code using the functions provided by the BSP to access the hardware ...Well this is just one way to look at it !

A board support package provides a abstraction of hardware by providing common functionality over which rest of the RTOS is built. For example, the scheduler does not change if the peripherals or even CPU is changed. Nor does the logic of Message Queue or semaphore implementation. But the booting process definitely changes when you choose a different CPU or even have diferent peripherals on board. A Board Support package then, eliminates these hardware specific details to be seperated from the rest of the RTOS code. Every time you design a new custom board, you need to write the BSP for it so that you may run your RTOS on it.

BSP orboard support package provides a abstraction layer of the hardware ,
When RTOS has to work on an Hardware Architecture the Device should be Compatible to os , BSP are this lowlevel drivers which stand in between the Hardware and OS
