src/bsp/lib: It contains two files. In printf.c, the form of subfunction in C
standard library is redefined to output printf information through UART.

Reference Design
After the installation, several basic reference designs can be found in
the demo folder of the installation directory or in the reference design zip at
the website; the reference design can be loaded into RDS for trial,
debugging and redeveloping by the way of importing. The reference
designs are shown as follows:
1.
ae250_demo: Demonstrates UART input/output and GPIO output of
the AE250.
2.
ae250_plic: Demonstrates the response of the interrupt controller to
interrupts, and provides demonstrations of the machine timer and pit
timer.
3.
ae250_freertos: Demonstrates that the AE250 ports embedded
real-time operating system FreeRTOS multi-threading running
program.
4.
ae250_ucosiii: Demonstrates that the AE250 ports embedded real-time
operating system uC/OS-III multi-threading running program.
