fw_setenv和fw_printenv共用一个文件,只是通过程序名来区分不同功能,所以我们在开发板创建一个fw_setenv的软连接就可以了。ln -s fw_printenv setenv 1配置得到fw_printenv和fw_setenv后还不能正常使用,还需要把tools/env/fw_env.config拷到板子/etc目录下...

This call performs to writes to the U-boot environment AFTER it was initialized and read via initr_env of board_r.c file (I believe). One of the calls is to put the /dev/mmcblk2p2 as the rootFS partition independent of the values written to it previously via fw_setenv ...

一、Uboot环境变量简介1.Uboot环境变量的作用在不改变源码、不用重新编译的情况下,可以使我们通过设置环境变量的值来改变uboot的一些设置,如bootdelay时间、机器码的值等等... resetUboot环境变量的设计逻辑是在启动过程中将env从静态存储器中读出放到RAM中,之后在uboot下对env的操作(如printenveditenvsetenv)都是...
I have been round and round with trying to get fw_setenv working but it never gets past the ioctl call with MEMERASE. However, fw_printenv is working fine. So I've come to the experts for help. root@module:/sbin#root@module:/sbin# fw_printenv csi_fs_devcsi_fs_dev=5root@module...
