      fw_setenv 修改 env报错, 报错权限问题,但修改权限后还是不行。

      root@(none):/mnt/extsd# fw_setenv boot_partition bootA
      Write error on /dev/by-name/env: Operation not permitted
      Error: can't write fw_env to flash
      
      root@(none):/mnt/extsd# ll /dev/by-name/
      UDISK        bootB        extend       rootfsB
      bootA        env          rootfsA      rootfs_data
      root@(none):/mnt/extsd# ll /dev/by-name/env 
      lrwxrwxrwx    1 root     root            14 Jan  1 00:00 /dev/by-name/env -> /dev/mtdblock7
      

      请问是还需要修改哪以一部分的权限设置。
