AM3354 从SD卡启动uboot，但无法进行emmc的烧录

我使用的是ti-processor-sdk-linux-am335x-evm-06.01.00.08，可以从SD卡启动uboot，但无法对emmc进行烧写，这是哪里出了问题，请大神帮帮忙

    参考以下帖子类似的报错问题，看一下能否解决。

    这个是不是因为mmc0_pin_mux配置问题，导致sd卡无法识别

    也有可能是pinmux的配置问题。
    emmc是接在哪个mmc上的？
    请贴出以下命令的打印信息看一下。
    => mmc list
    => mmc info
    请问是自制板吗？pinmux配置请检查<Processor SDK>/board-support/u-boot-<version>/board/ti/am335x/mux.c和设备树中的mmc配置。

    请问用的是mmc1接的emmc吗？上面提到的mmc1 pinmux配置部分再检查看看。

    主要需要检查mmc1 pinmux的哪些东西，第一次搞，不太清楚，还请多多指教

    把mmc1的配置修改后，好像可以识别了，但报

    这是问题内核的编译有问题嘛

    再确认一点，您现在是已经完成了emmc的烧写，但是启动之后报以上的错误是吗？
    启动方式修改过了吗？

    还没有烧写成功，应该是执行烧写脚本出了问题
