器件型号：SK-AM62-LP

您好！

我最终的目标是从 SK-AM62-LP 上的 Android SDK 9上的 SD 卡启动 Android。

我已经能够启动和运行引导加载程序、但每次我尝试使用 saveenv 保存环境时、都会出现无法保存环境的错误：

我认为这不是 SD 卡引导特定问题、因为我在尝试使用 USB DFU 引导以及仅从 SD 卡引导和写入 EMMC 时遇到了该问题。

我确实在 Android A53配置中看到设置了 CONFIG_SPL_ENV_IS_NOWATE=y 标志、但这与常规 SK 配置没有区别、这是否是个问题？

为什么我在 saveenv 上收到此错误？
