Following the prompt to set bundrate, word size, parity, stop bit for uart termination tool. Directories: 1.UART -- (main function & test function) | --- arch (CPU initialization & exception entry) | --- drivers (drivers required) | --- include (common header files) | --- lib (common functions) Target: cpu: ck802 soc: cksmart board: Usage: Under CDS: 1. open CDS and select a new workspace 2. import the 1.Uart project into the new workspace (project files: .cproject .project) 3. build project 4. new a debug configuration and debug the executable program Under Linux/windows console: 1. cd 1.Uart 2. make (project files: Makefile Rules.make) 3. csky-abiv2-elf-gdb Uart.elf(then connect target, download, run...) Ohters: Uart0 used as the termination, Default setting: 19200, 8, none, 1 output message when success: Testing uart... Default configure: Baudrate --- 19200,Parity --- NONE,Wordsize --- 8. - - -UART0 ready? [y] y - - - Testing uart mode... (query mode ): Output is--- ABCDEFGHIJKLMN- - - [y/n] y - - -PASS (interrupt mode ): Output is--- ABCDEFGHIJKLMN- - - [y/n] y - - -PASS - - - Test uart baudrate. Baudrate is 9600? [y] y :Output is --- ABCDEFGHIJKLMN- - -[y/n] y - - -PASS Baudrate is 14400? [y] y :Output is --- ABCDEFGHIJKLMN- - -[y/n] y - - -PASS Baudrate is 38400?

[y] y :Output is --- ABCDEFGHIJKLMN- - -[y/n] y - - -PASS Baudrate is 115200? [y] y :Output is --- ABCDEFGHIJKLMN- - -[y/n] y - - -PASS Baudrate is 19200? [y] y :Output is --- ABCDEFGHIJKLMN- - -[y/n] y - - -PASS - - - Test uart parity. (Parity: 0 --- ODD, 1 --- EVEN, 2 --- NONE) Parity is 0? [y] y :Output is --- ABCDEFGHIJKLMN- - -[y/n] y - - -PASS Parity is 1? [y] y :Output is --- ABCDEFGHIJKLMN- - -[y/n] y - - -PASS Parity is 2? [y] y :Output is --- ABCDEFGHIJKLMN- - -[y/n] y - - -PASS - - - Test uart wordsize. 0 --- WORD_SIZE_5, 1 --- WORD_SIZE_6, 2 --- WORD_SIZE_7, 3 --- WORD_SIZE_8 Wordsize is 2?
