## PS：
如果刚拿到板子请先把上电测试的帖子检查一下板子是都正常
## 接上tf卡但是先不要修改启动的设备
接上tf卡上电，检查mmc是否识别成功。mmc是否挂载成功## 烧录下载镜像到tf卡
1,下载群(群号464302622)里的pynq_z2_v2.3.zip，执行unzip pynq_z2_v2.3.zip解压。
2,sudo dd if=./pynq_z2_v2.3.img of=/dev/sdc(这里请修改成自己系3,统里的tf卡路径)
4,然后执行sync5,检查105MB大小的分区是都fat格式，如果不是fat格式的话就格式化分区为fat格式。
6,复制群共享里的BOOT.bin,fsbl.bif,linux.config,system.bit.bin,uEnv.txt,uImage,uramdisk.image.gz,zynq-ebaz.dtb到fat分区
7,将zynq-ebaz.dtb文件重命名为devicetree.dtb## 修改启动设备为tf卡

请问按照上述方法进行没效果怎么解决呀，谢谢！！！
梳理下操作：
1、更改电阻位置：R2584移植到R2577位置上；
2、将D2短接；
3、焊接好串口、tf卡座以及电源输出；
4、将sd卡用win32disk imager工具烧录镜像xillinux-2.0.img；
5、将fat分区原有的文件全部删除；
6、将以下文件全部移入fat分区中：BOOT.bin;fsbl.bif;system.bit.bin;uImage;uramdick.image.gz;zynq-ebaz.dtb;uEnv.txt;七个文件；
7、最后将文件zynq-ebaz.dtb重命名为devicetree.dtb；
8、打开串口，波特率为115200，上电；
9、发现emmmmm串口没打印信息，单板指示灯不亮。。。
最后麻烦各位大佬帮忙看看，拜托了
