petalinux_zynq7 C语言驱动DAC以及ADC模块之一：建立IP
https://blog.youkuaiyun.com/qq_27158179/article/details/136234296在上一篇，建立了ADC和DAC两个IP。这里继续。本文在 petalinux默认配置的基础上，添加了python和qt。再编译出sdk可以给x86主机交叉编译。
0. 环境
- ubuntu18
- vivado 2018.3
- mizar z7010 + ada106模块
1. petalinux工程创建
1.1 创建工程
cd /home/dell/work/mizar
source /opt/pkg/petalinux/2018.3/settings.sh
petalinux-create -t project -n linux_sd_adda --template zynq拷贝 hdf
把
/home/xxjianvm/work/mizar/linux_sd_hdmi/linux_sd_hdmi.sdk/hdmi_out_wrapper_hw_platform_0/system.hdf
拷贝到
/home/dell/work/mizar7/linux_sd_hdmi/hdf/system.hdf
1.2 用mizar开发板提供的linux内核
准备修改过的linux内核（添加了hdmi）
把
F:\开发板-FPGA资料、Mizar_Z7010_2018.3\03_Source\03_source.7z
拷贝到
/home/dell/work/mizar/03_source.7z
解压
7z x 03_source.7z
cd 03_source
mkdir -p ../petalinux_kernel/linux-4.14
tar -zvxf linux-4.14.0-v2018.3.tar.gz -C ../petalinux_kernel/linux-4.141.3 导入硬件描述配置
配置 Petalinux 工程的硬件信息，硬件信息目录里只能有一个 hdf 文件
cd linux_sd_hdmi导入硬件描述
petalinux-config --get-hw-description hdf/导入硬件描述后会自动弹出 menuconfig页面。
检查串口
Subsystem AUTO Hardware Settings -> Serial Settings -> FSBL Serial stdin/stdout (ps7_uart_1)
Subsystem AUTO Hardware Settings -> Ethernet Settings -> Primary Ethernet (ps7_ethernet_0)
Subsystem AUTO Hardware Settings -> SD/SDIO Settings -> Primary SD/SDIO (ps7_sd_0)配置SD卡
Image Packaging Configuration -> Root filesystem type -> SD card
Image Packaging Configuration -> Device node of SD device -> /dev/mmcblk0p2启动
Subsystem AUTO Hardware Settings -> Advanced bootable images storage Settings -> boot image settings -> image storage media (primary sd)
Subsystem AUTO Hardware Settings -> Advanced bootable images storage Settings -> u-boot env partition settings -> image storage media (primary sd)
Subsystem AUTO Hardware Settings -> Advanced bootable images storage Settings -> kernel image settings -> image storage media (primary sd)
Subsystem AUTO Hardware Settings -> Advanced bootable images storage Settings -> jffs2 rootfs image settings -> image storage media (manual)
Subsystem AUTO Hardware Settings -> Advanced bootable images storage Settings -> dtb image settings -> image storage media (from boot image)之后可以临时退出menuconfig页面了。
1.4 配置petalinux
第一次配置输入指令
petalinux-config第二次如果没修改hdf以及相关配置，输入指令
petalinux-config第二次配置如果修改了hdf
petalinux-build -x mrproper -f
petalinux-config第二次配置如果修改了配置：
petalinux-build -x distclean
petalinux-build内核源码
Linux Components Selection -> linux-kernel -> ext-local-src
Linux Components Selection -> linux-kernel -> External linux-kernel local source settings -> /home/dell/work/mizar/petalinux_kernel/linux-4.14配置 sstate 高速缓存（不是必须的）
petalinux-config -> Yocto Settings -> Local sstate feeds settings -> local sstate feeds url ->
-> file:///opt/pkg/petalinux/2018.3/sstate-rel-v2018.3/arm
petalinux-config -> Yocto Settings -> Add pre-mirror url ->
-> file:///opt/pkg/petalinux/2018.3/sstate-rel-v2018.3/downloads
petalinux-config -> Yocto Settings -> 取消 Enable Network sstate feeds
petalinux-config -> Yocto Settings -> 取消 Enable BB NO NETWORK # python的一个库需要联网此时保存配置退出。
1.5 配置内核
petalinux2018.3默认不支持远程中断配置内核，需要修改：
gedit project-spec/meta-user/conf/petalinuxbsp.conf添加：
OE_TERMINAL = "xterm"配置指令：
petalinux-config -c kernel配置 hdmi
（默认已经勾上）Device Drivers -> Graphics support -> <*>Xilinx LCD/HDMI drive
（默认已经勾上）Device Drivers -> Graphics support -> <*>Digilent VGA/HDMI DRM Encoder Driver
（默认已经勾上）Device Drivers -> Common Clock Framework -> <*>Digilent axi_dynclk Driver 按 y配置 usb gadget
Device Drivers -> USB Support -> <*>USB Gadget Support -> <*> RNDIS
Device Drivers -> USB Support -> <*>USB Gadget Support -> <*> Mass storage
Device Drivers -> USB Support -> <*>USB Gadget Support -> <*> Function filesystem1.6 配置根文件系统
petalinux-config -c rootfs
添加 python3
Filesystem Packages -> misc -> python -> python3 -> <*>python3添加 python3-pip，python3-flask
gedit project-spec/meta-user/recipes-core/images/petalinux-image-full.bbappend添加：
IMAGE_INSTALL_append = "python3-pip"
IMAGE_INSTALL_append = "python3-flask"配置
petalinux-config -c rootfs
user packages -> python3-pip
user packages -> python3-flask也可以（不过我用的是上面的方法，未确认下面的带不带flask）：
Petalinux Package Groups -> packagegroup-petalinux-python-modules -> <*>packagegroup-petalinux-python-modules添加 qt （编译时候看到版本是5.9.6）
Petalinux Package Groups -> packagegroup-petalinux-qt -> <*> packagegroup-petalinux-qt
Petalinux Package Groups -> packagegroup-petalinux-qt -> <*>populate_sdk添加 gcc （怀疑 libatomic在这里，尝试搭建nodejs + vue依赖libatomic）
Petalinux Package Groups -> packagegroup-petalinux-self-hosted -> <*>packagegroup-petalinux-self-hosted1.7 设备树
gedit project-spec/meta-user/recipes-bsp/device-tree/files/system-user.dtsi但是无法粘贴。修改为：
/include/ "system-conf.dtsi"
/ {
model = "Navigator Development Board";
compatible = "microphase,zynq-7020","xlnx,zynq-7000";
usb_phy0:usb_phy@0{

};

};
};1.7 编译工程
第一次编译
petalinux-build如修改配置编译：
petalinux-build -x distclean
petalinux-build1.8 打包boot.bin
petalinux-package --boot --fsbl ./images/linux/zynq_fsbl.elf --u-boot --fpga --force1.9 编译出sdk
petalinux-build --sdk
#petalinux-package --sysroot # 这个是安装指令。失败
| Cloning into '/home/dell/work/mizar/linux_sd_adda/build/tmp/work/x86_64-nativesdk-petalinux-linux/nativesdk-qemu-xilinx/v2.11.0-xilinx-v2018.3+gitAUTOINC+f70bd86859-r0/git/capstone'...
| fatal: unable to connect to git.qemu.org:
| git.qemu.org[0: 20.218.253.93]: errno=Connection timed out
解决办法：
修改文件：
/home/dell/work/mizar/linux_sd_adda/build/tmp/work/x86_64-nativesdk-petalinux-linux/nativesdk-qemu-xilinx/v2.11.0-xilinx-v2018.3+gitAUTOINC+f70bd86859-r0/git/.git/config
把
url = git://git.qemu.org/capstone.git
url = git://git.qemu.org/keycodemapdb.git
修改为：
url = https://gitlab.com/qemu-project/capstone.git
url = https://gitlab.com/qemu-project/keycodemapdb.git然后命令行模式进入目录
cd /home/dell/work/mizar/linux_sd_adda/build/tmp/work/x86_64-nativesdk-petalinux-linux/nativesdk-qemu-xilinx/v2.11.0-xilinx-v2018.3+gitAUTOINC+f70bd86859-r0/git执行命令
git submodule update之后，重新在工程目录下执行petalinux-build --sdk即可

2. 制作SD卡文件系统
2.1 分区
ubuntu18 -> disks -> 给8GB TF卡重新分区
-> + -> 5000MB -> Next
-> Volume Name: FAT
-> type: FAT
-> + -> 剩余 2858MB -> Next
-> Volume Name: EXT
-> type: ext4
-> 弹出TF卡 -> 断开连接 再次连接到虚拟机
2.2 EXT分区
sudo tar xzvf rootfs.tar.gz -C /media/xxjianvm/EXT
sudo sync
2.3 FAT分区
直接拷贝
BOOT.bin
image.ub
到FAT分区
2.4 启动测试
2.4.1 启动
拨码开关拨到SD模式。
开关都往下拨。
2.4.2 默认登录账号密码
root/root
