petalinux_zynq7 驱动DAC以及ADC模块之二：petalinux

petalinux_zynq7 C语言驱动DAC以及ADC模块之一：建立IPhttps://blog.csdn.net/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-4.14

1.3 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 filesystem

1.6 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-hosted

1.7 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{compatible = "ulpi-phy";#phy-cells = <0>;reg = <0xe0002000 0x1000>;view-port = <0x170>;drv-vbus;};video_timings {timing_4x3_480x272: timing0 {clock-frequency = <9000000>;hactive = <480>;vactive = <272>;hback-porch = <40>;hsync-len = <20>;hfront-porch = <5>;vback-porch = <8>;vsync-len = <3>;vfront-porch = <8>;hsync-active = <0>;vsync-active = <0>;de-active = <1>;pixelclk-active = <0>;};timing_1920x1080: timing1 {clock-frequency = <148500000>;hactive = <1280>;vactive = <720>;hback-porch = <148>;hsync-len = <44>;hfront-porch = <88>;vback-porch = <36>;vsync-len = <5>;vfront-porch = <4>;hsync-active = <0>;vsync-active = <0>;de-active = <1>;pixelclk-active = <1>;};};       
};&usb0{dr_mode = "host";usb-phy = <&usb_phy0>;
};&axi_dynclk_0 {compatible = "digilent,axi-dynclk";clocks = <&clkc 15>;#clock-cells = <0>;
};&v_tc_0 {compatible = "xlnx,v-tc-5.01.a";
};&amba_pl {xlnx_vdma_hdmi {compatible = "xilinx,vdmafb";status = "okay";xlnx,vtc = <&v_tc_0>;clocks = <&axi_dynclk_0>;clock-names = "hdmi_pclk";dmas = <&axi_vdma_0 0>;dma-names = "hdmi_vdma";is-hdmi = <0x1>;display-timings = <&timing_1920x1080>;xlnx,pixel-format = "bgr888";};
};

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-build

1.8 打包boot.bin

petalinux-package --boot --fsbl ./images/linux/zynq_fsbl.elf --u-boot --fpga --force

1.9 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
