[参考译文] AM625：如何自动执行整个 DFU-EMMC 刷写过程。

您好！

我已成功按照为 DFU 刷写脚本提供的步骤操作、在成功刷写 rootfs 后、我需要在 UART 控制台中执行特定命令。 但是、我的目标是自动执行整个刷写过程、无需在 UART 控制台中手动键入任何命令。

刷写脚本后、我需要在 UART 终端中执行以下步骤：

To give the ROM access to the boot partition, the following commands must be used for the first time:
        => mmc partconf 0 1 1 1
        => mmc bootbus 0 2 0 0

The above command sets up the EXT_CSD register of eMMC flash and enables boot from boot0 partition.

Power the EVM off. Set the boot switches [SW2:SW1] to eMMC boot. When the board is powering on, hit any key to stop u-boot auto-booting. Enter the following u-boot commands. Alternatively, these u-boot commands may also be built into u-boot.

To boot kernel from eMMC, use the following commands after writing rootfs to user partition:

setenv mmcdev 0
setenv bootpart 0
boot
The board should now boot from eMMC with the updated files.

如何将这些命令集成到 DFU-Flashing 脚本中以自动执行此过程？

谢谢。
