Uboot通过U_BOOT_ENV_LOCATION宏定义环境变量的存储位置,例如对于mmc其定义如下(env/mmc.c): U_BOOT_ENV_LOCATION(mmc) = { .location = ENVL_MMC, ENV_NAME("MMC") .load = env_mmc_load, #ifndef CONFIG_SPL_BUILD .save = env_save_ptr(env_mmc_save), .erase = ENV_ERASE_PTR(env_mmc_eras...

5.10 env_init 初始化环境变量有关的逻辑,不需要特别关注。 5.11 init_baud_rate 代码语言:javascript 代码运行次数:0 运行 AI代码解释 gd->baudrate=getenv_ulong("baudrate",10,CONFIG_BAUDRATE); 获取当前使用串口波特率,可以有两个途径(优先级从高到低):从"baudrate"中获取;从CONFIG_BAUDRATE配置项获取。
接下来我们来分析一下bootcmd默认配置,在默认环境变量default_environment(位于uboot-rockchip/include/env_default.h)中定义有,其内容大致如下: const uchar default_environment[] = { "bootcmd=" CONFIG_BOOTCOMMAND "\0" "bootdelay=" __stringify(CONFIG_BOOTDELAY) "\0" ...
4).假设文件系统是基于nfs的，bootargs的设置应该如下setenv bootargs ‘noinitrd mem=64M console=ttySAC0 root=/dev/nfs nfsroot=192.168.0.3:/nfs ip=192.168.0.5:192.168.0.3:192.168.0.3:255.255.255.0::eth0:off’或者setenv bootargs ‘noinitrd mem=64M console=ttySAC0 root=/dev/nfs ...
