23 | 
24 |
25 |
26 |
27 | ## Prepare
28 |
29 | ### 开发板
30 | 在根目录/conf/makefile.conf中修改如下配置:
31 | ```makefile
32 | # 开发板支持
33 | ARCH=arm32
34 | BOARD=ek-TM4C123gxl
35 | MCU=TM4C123GH6PM
36 | LINK_FILE=link.ld
37 | OCD_CFG_FILE=ek-tm4c123gxl.cfg
38 | ```
39 | 其中选项对应board下支持的开发版
40 |
41 | ### 配置OPENOCD
42 |
43 | ```makefile
44 | OPENOCD_SCRIPT_DIR=/usr/local/share/openocd/scripts/board
45 | ```
46 |
47 | ### 配置项目
48 |
49 | ```makefile
50 | BASE_DIR=/Users/neroyang/project/Ceno-RTOS
51 |
52 | ```
53 |
54 | ### 构建
55 |
56 | #### OPENOCD启动
57 |
58 | ```bash
59 | cd user
60 | make openOCD_connect
61 | ```
62 |
63 | #### 构建
64 |
65 | ```bash
66 | make all
67 | ```
68 |
69 | #### 烧写
70 |
71 | ```bash
72 | make flash
73 | ```
74 |
75 | ### 写在最后
76 | have a good trial!
