本次使用的Vivado, Petalinux版本均为v2021.1。记录下来方便自己和其他人之后参考。
1 Vivado部分
1.1 新建工程项目，FPGA选型器件为xc7z020clg400-2。
1.2 添加Block Design，加入Zynq7 Processing System IP核，并对IP核进行定制。
1.3 去除PS-PL Configuration->AXI Non Secure Enablement->GP Master AXI Interface->M AXI GP0 Interface的对勾，如图所示。
1.4 根据黑金AX7020提供的手册，按如图所示的配置配好Peripheral IO Pins。使能QSPI Flash，Ethernet 0，USB 0， SD 0，UART 1。对应的MIO从图中可以找到。配置两个Bank的电压。
1.5 根据黑金AX7020提供的手册，进入MIO Configuration，将Ethernet 0对应的IO Type和Speed分别改为HSTL 1.8V和Fast，否则可能无法正常上网。其他的选项无需改变。
1.6 根据黑金AX7020提供的手册，进入DDR Configuration，将Memory Part修改为MT41J256M16 RE-125。
1.7 Create HDL Wrapper，Synthesis，Implementation, Gen Bitstream，Export Hardware With Bitstream导出硬件配置xsa文件备用。
2 Petalinux部分
这部分的工程需要在Linux完成，我采用Ubuntu 18.04安装Petalinux v2021.1。
2.1 使用source命令导入petalinux的可执行程序路径
2.2 新建工程：
1 | petalinux-create --type project --template zynq --name AX7020 |
2.3 进入工作目录：
1 | cd AX7020 |
2.4 复制硬件配置文件xsa到linux下并导入
1 | petalinux-config --get-hw-description bd_top_wrapper.xsa |
2.5 进行Petalinux的配置
2.5.1 Subsystem AUTO Hardware Settings
进入Subsystem AUTO Hardware Settings，如有需要可以配置Ethener Settings中的MAC地址。其他选项可以保持默认不用动。
2.5.2 Image Packaging Configuration
进入Image Packaging Configuration，将Root filesystem type改为EXT4 (SD/eMMC/SATA/USB)。其他不用动。
2.6 进行u-boot的配置
老版本的Petalinux-config是可以通过Advanced bootable images storage Setting配置启动方式的，不知道为什么v2021.1没这个选项了，只能手动配置uboot了。
1 | petalinux-config -c u-boot |
进入Boot options->Enable a default value for bootcmd，改变bootcmd value为：
1 | fatload mmc 0:1 0x10000000 image.ub;bootm 0x10000000;run distro_bootcmd |
配置其从SD卡的image.ub内核启动。
2.7 编译
1 | petalinux-build |
2.8 生成BOOT.BIN和image.ub
1 | petalinux-package --boot --force --fsbl images/linux/zynq_fsbl.elf --fpga --u-boot |
在images/linux下会多出两个BOOT.BIN和image.ub。将这两个文件复制到SD卡的FAT分区，即可从SD卡启动。
SD卡应当有两个分区，首分区有Boot Flag，FAT格式，第二分区为EXT4，存放rootfs。在做rootfs的时候详细讲解。
3 rootfs部分
3.1 产生空白4G img映像，用来烧写文件系统
1 | dd if=/dev/zero of=AX7020_Ubuntu2004.img bs=1M count=4096 |
3.2 挂载映像
1 | sudo losetup -f --show AX7020_Ubuntu2004.img |
我的机器上，给我挂载到了/dev/loop31，下面都以loop31为例。
3.3 给映像分区
1 | sudo fdisk /dev/loop31 |
按照下列过程给磁盘分区：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 | jack@ubuntu:~/AX7020/bootstrap$ sudo fdisk /dev/loop31 Welcome to fdisk (util-linux 2.31.1).

同步分区：
1 | sudo kpartx -av /dev/loop31 |
格式化分区：
1 2 | sudo mkfs.vfat /dev/mapper/loop31p1 sudo mkfs.ext4 /dev/mapper/loop31p2 |
挂载：
