1.1 U-boot移植

在进行uboot移植以前，先对uboot目录进行备份，已被日后还原使用。我这里备份了uboot的整个目录

(u-boot-xlnx)，Uboot文件夹结构如下。

/arch /arm /cpu /arm720t /arm920t /at91 /imx /s3c24x0 /arm925t /arm926ejs /arm1136 /ixp /pxa /s3c44b0 /sa1100 /lib /avr32 /cpu /lib /blackfin /cpu /lib /x86 /cpu /lib /m68k /cpu /mcf52x2 /mcf5227x /mcf532x /mcf5445x /mcf547x_8x /lib /microblaze /cpu /lib /mips /cpu /mips32 /xburst /lib /nds32 Architecture specific files

Znyq-7000综合开发文档 /tools 1.1.1

Tools to build S-Record or U-Boot images, etc. uboot配置

在做配置以前，认为uboot已经执行了配置命令，并在 uboot安装目录生成了配置文件，配置文件位于 ”uboot所在目录/include/configs/.h”

1.1.1.1 根据开发板的实际情况，配置在uboot中配置DDR、flash接口等模块。

(1) 内存配置

u-boot-xlnx\\board\\xilinx\\zynq_common\\lowlevel_init.S (2) 开发板初始化

u-boot-xlnx\\board\\xilinx\\zynq_common\\board.c

board_init()函数，完成板子的初始化操作，用户可根据需要添加自己的代码。 (3) 添加xmodule支持

u-boot-xlnx\\common\\cmd_load.c

其实现方法类似load_serial_ymodem()函数，代码如下，添加该代码后即可使用SecureCRT连接设备。 依照load的形式编写代码，依照cmd的格式添加指令，如下 U_BOOT_CMD(

loadx, 3, 0, do_load_serial_bin,

\ \

\ - load binary file over serial line\ \);

然后在do_load_serial_bin()函数中添加如下代码 if (strcmp(argv[0],\

printf (\ \ offset, load_baudrate); addr = load_serial_ymodem (offset); }

else if (strcmp(argv[0],\ … … } else{ … … }

生命函数

#if defined(CONFIG_CMD_LOADB)

static ulong load_serial_ymodem (ulong offset); static ulong load_serial_xmodem (ulong offset); #endif

依照load_serial_ymodem()函数实现,实现load_serial_xmodem() 拷贝load_serial_ymodem()函数，重命名为load_serial_xmodem(); 修改ymodemBuf[1024]变量名为xmodemBuf[1024]; 这里需要关注两个地方

1.2 程序烧写

1.2.1 FSBL文件创建

Xilinx arm的启动过程分为两个部分FSBL+UBOOT

(1) 这里假设应经创建了一个硬核，并导入到SDK中，此时SDK环境下只有hw_plate工程。 (2) 创建BSP，具体操作过程详见以前章节。 (3) 导入FSBL工程，
