前段时间手头事情比较多，下班抽出点时间来研究研究MYD-C7Z010/20开发板，每次尝试都所收获。在此贴中，我将本人在使用Linux环境编译上遇到的问题与大家共同分享，希望能够对后续开发体验人员有所借鉴。关于搭建Linux环境我耗费了好长时间，可能是因为个人电脑比较老旧的原因，之前开发过海思的安防类产品，是基于Linux平台的，然而后面没有再继续从事基于Linux平台的项目开发，因此就将电脑里搭建好的Linux环境给卸载掉了。现在重新搭建，感觉走了不少坎坷之路。
首先第一次尝试，采用米尔官方提供的光盘中“03-Tools”文件夹下的VirtualBox工具与Ubuntu10.04系统文件来搭建Linux环境，虽然安装了VirtualBox增强工具，结果还是没法共享windows 7中的文件，只能强行地将文件夹Toolchain下的“Sourcery_CodeBench_Lite_for_Xilinx_GNU_Linux.tar.bz2”拖拽到Ubuntu10.04虚拟桌面上，结果再去执行tar命令，结果解压出来的文件没有gcc，导致后续设置交叉编译工具后，编译Uboot报未找到gcc编译器。以上总结是因为没有共享win7中的原始文件，生拉强拽会损坏.tar.bz2文件。
其次第二次尝试使用“VMware-workstation-full-10.0.7”与“ubuntu-16.04.3-desktop-amd64”搭建虚拟机开发环境，结果一开始就报"The Msi Failed"，网上搜索解决良策，原来是因为之前的VMware没有卸载干净，正如附件中《VMware安装异常解决》中所述，然后根据网友的提示，删除注册表中含有VMware10软件的信息。结果很快顺利的装上了VMware10，但安装完ubuntu-16.04.3-desktop-amd64系统镜像后，仍然提示没法共享Win7系统文件，然后在网上下载了60M大小的linux.iso镜像，使用VMware10加载，VMware工具增强了，可以实现文件自由挂载、共享。但是编译Uboot时会报原始文件与当前的64位ubuntu不匹配，因此还得换成32位的ubuntu系统。
接着第三次搭建Linux环境，查阅网上相关资料，选择采用VMware Workstation 12 Pro的工具，搭配官方光盘中的Ubuntu10.04系统镜像，这才顺利的实现了与Win7文件共享，完美支持从windows中拷贝指令到Terminal终端中执行，这样工作的效率大大调高了。然后根据基于Linux开发手册指南，按部就班的操作，但是遇到了连不上相对应的远程服务器的问题，原来采用ubuntu-16.04.3-desktop-amd64系统镜像可以更新，但是采用官方光盘中的Ubuntu10.04系统镜像就不能更新，老是报error，超时，原本以为是VMware的网络适配器选择错了，但都是选择的桥接模式。后面在百度上搜索了相关问题，得知是因为Ubuntu10.04系统比较旧的原因，软件更新源过期无法再链接到官方指定的远程服务地址上，然后我在网上找到了解决办法的帖子，更换了source.list文件，其原始目录在“/etc/apt/”目录下，很快就能执行“sudo apt-get update”。source.list源码文件如下：

当然如果碰到“动态MMap没有空间了”提示，可以参考如下图所示的解决办法。更新完毕后再执行手册中提到的安装必要的工具指令，才能进行Uboot的编译，否则会报错。
必须更换软件更新源的链接说明如下：
只要更新问题解决，共享文件没有问题，后面就是一路凯歌，如下图所示，编译Uboot成功，编译内核成功
生成Uboot二进制文件，然后将它拷贝到“02-Images”文件夹目录下
编译内核信息如下
内核编译可能需要花点时间，我的电脑可能有点老旧，花了大约16分钟。最后内核编译成功，生成的二进制文件uImage以及dtb文件
然后将生成的可执行二进制文件，按照操作手册指南，拷贝到内存卡的根目录下，然后启动板卡，通过串口可以看到烧写的具体信息
当然如果我们将官方提供的Uboot二进制文件直接扔到内存卡的根目录下，板卡启动后就相当于执行了一段裸板程序，串口打印Hello world信息

综上所述，MYD-C7Z010是一块工业级开发板，既能使用Vivado工具开发FPGA程序，又能使用Linux开发环境编译内核源码，不愧为FPGA+ARM的嵌入式开发板，板载资源非常丰富，如果配有触摸屏那就更好了，将有更多的功能，更好的UI界面可以体验。开发板配有相关的视频教程那更完美了，不过文档也介绍的比较详细。好了，此次评测就与大家分享到这里，后续再对MYD-C7Z010的外设存储进行深入了解，欢迎指点迷津，谢谢！
