内核日志显示 ubi 访问失败。 如果您可以在 Linux 中访问 NAND MTD 器件、则可以从其他源而不是 NAND 启动、然后检查。

您好！

除了 NAND 之外、没有其他引导器件

为给您一些背景信息、
此定制板采用 SDK 版本02.00.01.07进行大规模生产。

我将 SDK 版本更新为08.02.00.0024并进行测试、然后出现此问题。

我们希望硬件不会出现问题、只需更改 SDK 版本即可。

但是、我不知道最新的 SDK 支持和闪存完美性。

从日志中、它似乎是一个与 ECC 相关的错误。

此外、 在启动开始之前、上电时  显示"OMAP-elm：不可纠正的 ECC 错误"。

u-boot 是否正确支持 nand 控制(ECC、bch8...)？

谢谢你。

你好，刘斌

您能告诉我们如何转储 GPMC 寄存器吗？ 我们需要更详细的指令、以便至少将 GPMC 寄存器转储到 EVM 上。
