犹豫前段时间一直在搞另一个项目，Am335x这个BBlack板就放置一边了。前几天把BBlack板重新拿到手，之前搞得给全忘了。SD卡烧写emmC时突然出现了错误，一直找不到原因，今天终于算是有点眉目了，就录下来省得下次又忘记了。
之前的SD卡烧写eMMC bolg：https://www.cnblogs.com/BigOBlue/p/8513067.html
之前不能分区出现的错误：log：

经过多次试验依然是上面的log，最后不得已重现编译了内核用的是3.14.65，重新烧写对应的uImage。依然没有成功，错误信息：

用重新编译的内核，发现Uboot起来了，但是不能引导内核，一直卡在Starting kernel ...这里，从网上查资料还想象设备树有关，进而重新编译设备树，但是依然没有通过还是卡在Starting kernel ...这里。重新对比了设备树发现虽然不编译了设备树，但是设备树并没有更新。进入内核找到设备树，找到am335x-boneblack.dtb，删除，重新编译，获取新的设备树。然后按之前写的SD卡烧写eMMC方式，重新制作SD卡。这次就好了。
出现卡死Starting kernel ...的原因，我猜是uImage和设备树不匹配（版本或者其他什么原因）。

找到原因之后才想起来之前有一次将ti提供的SDk里的uImage,和设备树替换了我之前编译的uImage和设备树。导致了SD卡不能烧写eMMC，和卡死在Starting kernel ...的问题。
至于为什么用Ti的SDK里的内核编译的uImage和dtb怎么不行，后续在研究研究，估计内核有什么没有配置。
续昨天的 “”“用Ti的SDK里的内核编译的uImage和dtb怎么不行”
今天找到了为什么用Ti SDk的编译的内核和Dtb怎么不行了。
之前估计要用到EMMC的引脚与其他的功能冲突了，所以我把Ti_SDK里的Dtb（am335x-bone-common.dtsi）里边关于emmc的引脚配置给注释掉了，所以导致用Ti——SDK的内核编译的DTB没有支持eMMC，所以利用TiSDK编译的内核和设备树就不能识别eMMC了。最终SD卡里的脚本也不会对eMMC分区了。
