尊敬的 TI 专家：

我尝试使用 DFU 将 rootfs 二进制文件(2.5GB)刷写到 eMMC。但是、其故障百分比始终与下面的相同。

您好 JaeWook：
如果以前没有这样做、我们是否可以将 GPT 分区表添加到 eMMC？
此操作可以通过@u-boot 来完成
software-dl.ti.com/.../UG-Memory.html

在将 GPT 分区表添加到 eMMC 之后、我们是否可以使用 USB-DFU 重新测试 rootfs.ext4？

此致！

尊敬的洪冠：

感谢您的反馈。

我已在之前的中添加了 GPT 分区表、如下所示

=>MMC 部件

MMC 设备0的分区映射--分区类型：EFI

零件开始 LBA 结束 LBA 名称
属性
键入 GUID
分区 GUID
1 0x00000022 0x01da3fde "rootfs"
attr：0x000000000000
类型：ebd0a0a2-b9e5-4433-87c0-68b6b72699c7
GUID：731a396e-ea6f-49bc-ac52-3e97f76eb198

在刷写 tisdk_BASE_rootfs (约400MB)二进制文件时没有问题。

谢谢。此致、

Unknown 说：
，并且我刷入 tisdk_base_rootfs (约400MB)二进制文件时没有问题。

根据您上次的回复、我的理解是 ROOT_FS eMMC 刷写在您的设置中发挥了作用。
自那时以来发生了什么变化？
此致！

尊敬的洪冠：

源代码和设置环境没有变化。

只有 rootfs 文件的大小从400MB 增加到2.5GB。

因此、eMMC 的面积发生了变化。

谢谢。此致、

尊敬的洪冠：

我发现 eMMC 写入失败的一种模式是由于这个问题。

当我尝试写入3个以上的0xFF00FF00数据块时、总是会发生 MMC 写入失败。

我按如下所示在 u-boot 提示符中复制了"MMC 写入失败"。

=> mw 0x80080000 0xFF00FF00 0x800
=> mmc write 0x80080000 0x10000 1

MMC write: dev # 0, block # 65536, count 1 ... 1 blocks written: OK
=> mmc write 0x80080000 0x10000 2

MMC write: dev # 0, block # 65536, count 2 ... 2 blocks written: OK
=> mmc write 0x80080000 0x10000 3

MMC write: dev # 0, block # 65536, count 3 ... mmc write failed
0 blocks written: ERROR

请检查此项。

谢谢。此致、

您好、Hong：

让我总结一下到目前为止的情况。
起初、在刷写 tisdk-default-image 二进制文件时 eMMC 写入失败。
调试后、我发现如果二进制文件包含特定数据(0xFF00FF00)、该二进制文件会失败。
它可以使用上述相同的命令轻松复制。
同样的问题发生在我们团队的所有3个板上。
我希望您也可以轻松地复制它。

请检查此问题。

我认为对于使用 AM62x EVM 或 SDK 的任何人来说、这是一个主要问题。

谢谢、此致(&R)、

Jaewook.

您好 JaeWook：
您是否要通过将"0x80080000"替换为"$｛loadaddr｝"来帮助重新运行测试？
此致！
