3 脚本参数说明

4 脚本操作说明

5 脚本代码

1 脚本名称

ccode_standard

2 脚本路径

/scripts/bin/ccode_standard

3 脚本参数说明

次序	参数名	说明
1	address (./rfdig；.；..；./boot)	指定脚本执行路径（可以为脚本所在路径的任意相对路径）
	help	脚本使用帮助，打印说明信息
2	all	运行脚本后，脚本会解析全部rbus.cfg，并对参数1指定的目录中的.c文件进行寄存器配置代码标准化修改
	module_name_seca.cfg	运行脚本后，脚本会解析参数2指定的rbus.cfg，并对参数1指定的目录中的.c文件进行寄存器配置代码标准化修改
示例	命令：ccode_standard help 输出ccode_standard使用帮助信息
	命令：ccode_standard ./rfdig rfdig_seca.cfg 对当前路径下的rfdig文件夹及其子文件夹下所有的.c文件中，有关rfdig_seca.cfg中的寄存器配置代码进行标准化修改；
	命令：ccode_standard . crg_seca.cfg 对当前路径下的所有文件夹及其子文件夹下的所有.c文件中，所有有关crg_seca.cfg中的寄存器配置代码进行标准化修改；
	命令：ccode_standard . all 对当前路径下的所有文件夹及其子文件夹下的所有.c文件中，所有模块的寄存器配置代码进行标准化修改；
说明	配置文件module_name_seca.cfg是被验模块寄存器的详细配置文件；脚本索引该文件的具体路径为： $PROJ_SRC/design/scripts/rbus_scripts/rbus_cfg/ 使用该脚本前请先gen_rbus；

4 脚本操作说明

该脚本用于将如下所示的代码标准化，加速ST用例调整，该脚本可以反复多次调用，不会产生异常问题：

使用脚本前，首先gen_rbus，source，产生脚本需要解析的rbus.cfg文件，以及环境变量$ENV{PROJ_SRC}；
根据脚本存放路径，指定脚本工作目录，如下例所示，脚本存放于case目录，我想修改rfdig文件夹下的.c文件，参考rfdig_seca.cfg；执行：ccode_standard ./rfdig rfdig_seca.cfg > 1.log
如图所示，脚本只替换了有关rfdig的寄存器，iomux，crg等没有替换：
如下例所示，脚本存放于case目录，我想修改rfdig/rfdig_tc017文件夹下的.c文件，参考所有rbus.cfg文件；
执行：ccode_standard ./rfdig/rfdig_m33_tc017 all > 1.log
如图所示，脚本不仅替换了有关rfdig的寄存器，iomux，crg等都有替换：
