|
* @brief Hardware Related Package includes board support package(BSP) and CSP(Chip
|
|
* Support Package).
|
|
*
|
|
* Board Support Package(BSP) is the hardware related wrapper, for example, peripherals
|
|
* in board, the pinmux setting etc. In RT-Thread RTOS, the bsp is placed under bsp
|
|
* directory.
|
|
*
|
|
* Chip Support Package(CSP) is a software set that contains chip specific software.
|
|
* A CSP usually includes operating system porting and peripheral device drivers inside
|
|
* chip. In RT-Thread RTOS, the csp is placed under libcpu directory.
