器件型号：AM625SIP
主题中讨论的其他器件： AM625

工具/软件：

大家好、我正在尝试在 sdk10中的 AM625SIP 上实现 falcon 模式。我关注了这个论坛 e2e.ti.com/.../am625-how-to-setup-u-boot-falcon-boot-by-sdk-09_00_00_03

这是我的 tispl.its 文件：

您好、

您是否也修改了器件树文件以将 rootfs 保留在 SD 卡中、如说明中引用的 E2E 主题中所述？

您好、Suren、

是的、我已经将这一更改应用于常规 DTB。

我认为由于我使用的是 MMC 1、所以应该使用/dev/mmcblk0p2. 我尝试了 mmcblk0p2和 mmcblk1p2、结果相同。

您好、Josiah：

MMC 1 - SD 卡

MMC0是 EMMC

能否在 FDT_ERR_BADMAGiC 指向设备树 blob 格式问题时再次检查设备树？
