petalinux编译zynq的linux

首先要在vivado里建立工程。

工程建立完成一般流程综合，实现，比特流

综合后如果有引出的模块要分配外接的管脚。

生成比特流后导入到SDK就可以了

这时候工程已经有bit流文件和hdf硬件顶层设计文件。

source一下petalinux的环境

使用petatlinux建立工程，petalinux-creat --type project --template zynq --new 文件名

就会在当前目录先建立文件名的文件夹

cd到文件夹

petalinux-config --get-hw-description=<hdf文件的路径>

然后开始配置：

petalinux-config -c u-boot

--Device Drivers DMA Support ---> [*] Enable Driver Model for DMA drivers

FPGA support ---> [*] Enable Xilinx FPGA drivers │ │

│ │ [*] Enable Xilinx FPGA driver for ZynqMP

I2C support ---> [*] Enable Driver Model for I2C drivers

[*] Network device support ---> [*] Xilinx AXI Ethernet │ │
│ │ [*] Xilinx Ethernetlite │ │

│ │ [*] Xilinx Ethernet GEM

[*] USB support --->

petalinux-config -c kernel

[*] Networking support ---> Networking options ---> [*] IP: DHCP support │ │
│ │ [ ] IP: BOOTP support │ │

│ │ [*] IP: RARP support

petalinux-config -c rootfs

Filesystem Packages --->

libs ---> ffmpeg ---> [*] ffmpeg

console ---> utils ---> file ---> [*] file

console ---> utils ---> unzip ---> [*] unzip

console ---> utils ---> vim ---> [*] vim

$ petalinux-package --boot --fsbl --fpga --u-boot

zynq> flashcp -v BOOT.BIN /dev/mtd0 zynq> flashcp -v uImage /dev/mtd1 zynq> flashcp -v devicetree.dtb /dev/mtd2 zynq> flashcp -v uramdisk.image.gz /dev/mtd3

fatload mmc 0 0x1000000 image.ub

bootm 0x1000000

You can find all the modules in this directory:build/tmp/work/plnx_aarch64-xilinx-linux/linux-xlnx/4.9-xilinx-v2017.3+gitAUTOINC+f1b1e077d6-r0/image/lib/modules/4.9.0-xilinx-v2017.3/

it should list your modules with "find -name *.ko " command also.

and for the kernel modify

after build the kernel you will find the source code in the

<plnx-proj-root>/build/tmp/work-shared/plnx_arm/kernel-source

1. modify the code source in the <plnx-proj-root>/build/tmp/work-shared/plnx_arm/kernel-source

for example: drivers/w1/masters/w1-gpio.c

2. in the <plnx-proj-root>/build/tmp/work-shared/plnx_arm/kernel-source do like this

git add file1(like:drivers/w1/masters/w1-gpio.c) file2 ...

3. give a pacth tile

git commit -s -m 'your commit title'

4.create the pacth

git format-patch -1

#and then you will see the .pacth in you current directory.

5. copy this .pacth to the <plnx-proj-root>/project-spec/meta-user/recipes-kernel/linux/linux-xlnx/

and add the linux-xlnx_%.bbappend file in the <plnx-proj-root>/project-spec/meta-user/recipes-kernel/linux/

like:
SRC_URI_append = " file://xxxx.patch"

FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:"
