您好！

这是 MBR DOS 分区表。 您可以使用 Linux 内核中的`fdisk`命令创建此功能。

随附示例

root@am62xx-evm:~# fdisk /dev/mmcblk0

Welcome to fdisk (util-linux 2.37.4).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Device does not contain a recognized partition table.

这是一个通用命令、因此您可以在互联网上找到更详细的指南。

谢谢 Prashant、非常感谢

Prashant、您好！
我已经完成了下面这样的分区,但我使用了 initramfs ,因为我不使用 SD 卡。

此外,当写入分区和 Mount 也不工作时,也会出现上述错误。
您能对此提供帮助吗？

您不需要传递任何附加参数、因为 mount 命令会自动检测格式

root@am62xx-evm:~# mount /dev/mmcblk0p1 /mnt
[  122.510060] FAT-fs (mmcblk0p1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.
root@am62xx-evm:~# ls /mnt
tiboot3.bin
root@am62xx-evm:~#

我也尝试过、但没有解决问题

您能否说明使用 initramfs 和 mouting eMMC 的原因？

如果是要刷写 eMMC、您可以通过从 SD 卡引导 Linux 内核来执行此操作。

我不使用 SD 卡、并尝试使用 initramfs 进行刷写、然后装入 eMMC。

有什么方法可以做到这一点吗？
