前言

介绍U-Boot和驱动相关的内容。

一、U-Boot概述

U-Boot是一个开源的通用引导加载器，Xilinx提供了一个位于GitHub - Xilinx/u-boot-xlnx 的仓库，其中包含了在Xilinx板上运行的U-Boot。

U-Boot也有自己的命令，感觉挺有意思的：

?       - alias for 'help'
base    - print or set address offset
bdinfo  - print Board Info structure
boot    - boot default, i.e., run 'bootcmd'
bootd   - boot default, i.e., run 'bootcmd'
bootm   - boot application image from memory
bootp   - boot image via network using BOOTP/TFTP protocol
cmp     - memory compare
coninfo - print console devices and information
cp      - memory copy
crc32   - checksum calculation
date    - get/set/reset date && time
echo    - echo args to console
editenv - edit environment variable
erase   - erase FLASH memory
ext2load- load binary file from a Ext2 filesystem
ext2ls  - list files in a directory (default /)
fatinfo - print information about filesystem
fatload - load binary file from a dos filesystem
fatls   - list files in a directory (default /)
fdt     - flattened device tree utility commands
flinfo  - print FLASH memory information
go      - start application at address 'addr'
help    - print command description/usage
iminfo  - print header information for application image
imls    - list all images found in flash
imxtract- extract a part of a multi-image
itest   - return true/false on integer compare
loadb   - load binary file over serial line (kermit mode)
loads   - load S-Record file over serial line
loady   - load binary file over serial line (ymodem mode)
loop    - infinite loop on address range
md      - memory display
mm      - memory modify (auto-incrementing address)
mmc     - MMC sub system
mmcinfo - display MMC info
mtest   - simple RAM read/write test
mw      - memory write (fill)
nfs     - boot image via network using NFS protocol
nm      - memory modify (constant address)
ping    - send ICMP ECHO_REQUEST to network host
printenv- print environment variables
protect - enable or disable FLASH write protection
rarpboot- boot image via network using RARP/TFTP protocol
reset   - Perform RESET of the CPU
run     - run commands in an environment variable
setenv  - set environment variables
sf      - SPI flash sub-system
sleep   - delay execution for some time
source  - run script from memory
sspi    - SPI utility commands
tftpboot- boot image via network using TFTP protocol
version - print monitor version

目前眼熟的命令可能也就是tftpboot，在petalinux-package时出现过！

U-Boot提供了两条指令引导启动镜像，booti命令用于引导传统的U-Boot镜像或新的多组件镜像（FIT格式）。bootm命令则用于在引导前重新定位镜像，使其地址可能与内核看到的地址不同，并会修改设备树以指示内核ramdisk镜像在内存中的位置。具体可以参考官网的信息。感觉还是挺实用的，但目前还没用到，先不管了！

二、Xilinx官方给出的U-Boot驱动程序

1、U-Boot Ethernet Driver

2、U-Boot GPIO Driver

3、U-Boot UART Driver

4、U-Boot I2C Driver

5、U-Boot USB Driver

6、U-Boot axi spi/qspi driver

7、U-boot axi uart-lite driver

8、U-boot axi ethernet

9、U-boot axi ethernet-lite driver

10、还有其他的驱动，可以翻翻！

以上大多数都附了设备树代码，可以拿来参考！我在博客简单做个链接汇总，便于后续查找！

另外，可以在项目文件中找到配置文件：

dention@ubuntu:~/petalinux_proj/test_peta/proj_peta$ grep -rl "CONFIG_ZYNQ_GEM" ./
./project-spec/meta-plnx-generated/recipes-bsp/u-boot/configs/config.cfg

该文件内容如下：

三、Xilinx官方给出的Linux驱动程序

就放个链接吧！提供的内容有很多！

根据xilinx-wiki的说法，由于历史原因，内核树中有许多驱动程序，它们可能可以工作，但以下列出的驱动程序是当前经过测试的，鼓励用户使用这些驱动程序而不是其他驱动程序。任何其他不在主线上的驱动程序，且仅在Xilinx树中，可能已经过时，并且可能随时被移除。

所以，稳妥起见，Linux官方的设备树和Xilinx官方提供的设备树都需要参考！

另外也翻到一个线上查阅设备树的网址。

到这里，资料整理得差不多了，初步的上手实验也做了，需要进一步深化一下了！

总结

本文介绍U-Boot和驱动相关的内容，提供了用于学习的重要链接。简简单单水一篇！开干！！！
