器件型号：SK-AM64B 工具与软件：
大家好、团队成员：
SDK 版本：ti-processor-sdk-linux-am64xx-evm-10.00.07.04
我们在 SK AM64B 板中完成了一些返工、以通过 MMC1接口从外部连接 EMMC。
然后、我们尝试通过 USB DFU 在 EMMC 上刷写映像。 我们可以成功通过 USB DFU 引导、但在此之后、我们看到初始化 EMMC 时出现问题、如下所示：

foe emmc 在 mmc1接口上支持我们做了以下更改:
1更新 DFU 闪存实用程序：
DFU_FLASH/FRAC/parse.py + 20 src
更新了 FLASH_media。 eMMC："dfu 0 mmc 0"到 flash_media。 eMMC："dfu 0 mmc 1"
您能否提供还需要进行哪些其他更改？
