vivado

安装mingw，添加vivado工具到环境变量E:\Xilinx\Vivado\2015.2\bin，执行make，此次耗时较久，本以为卡住，敲了回车键才知道编译已经完成，

$

可以看到，这个工程用到了三个库，

axi_clkgen
axi_hdmi_tx
axi_spdif_tx

参考ug954，ps的iic和pl的iic均可控制所有外设，

no-os

新建工程，添加源代码E:\no-OS-2015_R2\adv7511\zc706，添加库E:\no-OS-2015_R2\adv7511\library\zc，目录如下，刷新编译，

sdk2015.2.1好像有问题，在standalone模式下，头文件路径在这儿配置，

库目录在这儿配置，

no-os测试

输入0~6可以改变分辨率，实际测试这个程序输出的屏幕在闪烁，需要改进，

用到以下驱动，

compatible = "adi,adv7511";，位于drivers\gpu\drm\i2c\adv7511.c，xilinx官方有，但是版本不一样，使用ADI
compatible = "xlnx,axi-vdma";，位于drivers\dma\xilinx_dma.c，xilinx vdma驱动，在xilinx官方内核目录没有该文件，已经废弃或者是adi自己维护的，目前dma驱动位于位于drivers\dma\xilinx\xilinx_vdma.c，使用ADI，使用Xilinx则drm驱动编译不过，DMA的头文件不一样，更改驱动注册的name解决和官方驱动的冲突，官方2015.2.1和ADI 2015_R2内核版本不一样，内核dma驱动的api修改了，编写device_control完成device_config，添加并修改Kconfig/Makefile
compatible = "adi,axi-clkgen-2.00.a";，位于drivers\clk\clk-axi-clkgen.c，xilinx官方有，但是版本不一样，使用Xilinx
compatible = "adi,axi-hdmi-tx-1.00.a";，位于drivers\gpu\drm\adi_axi_hdmi\axi_hdmi_drv.c，xilinx官方没有，使用ADI，添加并修改Kconfig/Makefile，注意修改include\drm\drm_edid.h增加drm_connector_get_edid函数
compatible = "adi,axi-spdif-tx-1.00.a";，位于sound\soc\adi\axi-spdif.c，xilinx官方有，版本相同
compatible = "adv7511-hdmi-snd";，位于sound\soc\adi\adv7511_hdmi.c，xilinx官方没有，使用ADI，添加并修改Kconfig/Makefile

配置内核menuconfig，

Linux开机打印，

这个时候可以在屏幕上看到串口的终端打印了，退出休眠

Linux测试

注意ZC706的千兆网phy地址是7，需要检查u-boot和设备树是否正确。

Linux安装

官网下载image，拷入SD卡运行，xz文件用unxz解压，tar命令是不行的，

$ time unxz 2014_R2-2015_02_06.img.xz
$ sudo umount /dev/mmcblk0p1
$ time sudo dd if=2014_R2-2015_02_06.img of=/dev/mmcblk0 bs=4M

制作完后，SD卡包含两个分区，一个FAT32 BOOT分区，一个ext4根文件系统，重新插入PC，校验，

$ sudo fsck -y /dev/mmcblk0p1
$ sudo fsck -y /dev/mmcblk0p2

将SD卡对应板卡的BOOT.BIN等拷入BOOT分区，启动，可以看到adi定制的linaro桌面

Windows安装

使用7zip解压xz文件
使用Win32DiskImager或者physdiskwrite将img写入磁盘，physdiskwrite还支持命令行模式
