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...
setenv bootargs ‘mem=32M console=ttyS0,115200 root=/dev/ram rw init=/linuxrc’注意这种情况下你应该要在bootm命令中指定ramdisk在flash中的地址，如bootm kernel_addr ramdisk_addr (fdt_addr)3). 假设文件系统是jffs2类型的，且在flash中，bootargs的设置应该如下 setenv bootargs ‘mem=32M console=ttyS...
