memory - uboot 环境变量保存好像不起作用

Question

我在尝试在 uBoot 中保存环境变量并让它们在重新启动后持续存在时遇到问题，请参见下面的跟踪。这是 U-Boot 2009.08-00000-g19b0e8d-dirty(2012 年 5 月 29 日 - 16:09:40)。关于可能出什么问题的任何想法？ “正在写入闪存...闪存未删除”消息是否重要？

Answer 1

在使用“fw_setenv”更新我的 U-Boot 环境后，我遇到了类似的问题。

我发现我的 U-Boot 在 fw_setenv 从 Linux 锁定后无法解锁环境扇区。一切看起来都很好，但是写入会像您一样失败。

我能够通过使用 flash_unlock 从 Linux 解锁 env 扇区来解决我的问题。
