UBL 是 RBL 引导启动的一段小程序，主要负责初始化时钟，串口，NAND，DDR2 等，然后把 uboot, kernel, rootfs 复制到 DDR2 上并引导 uboot。为什么 UBL 跟串口启动一起讲，那是因为这两个关系很密切，很多代码是共用的，而且代码都放在同一个目录下，所以就合起来一起讲了。
一、UBL
ubl 的代码放在 dvsdk 目录下的/psp/flash-utils 文件夹。 flash-utils 目录里有很多基于不同平台的文件夹，但对我 DM36x 来说，只需要 Common 和 DM36x 两个文件夹就可以了，其他的都可以删掉，而且删掉后清爽多了，呵呵。UBL 的源码分析网上已经很多人介绍了，我移植的时候参考了一篇很好的文章：http://zjbintsystem.blog.51cto.com/964211/392000
1. 各个 makefile 的修改
修改各个目录下的 makefile，主要是屏蔽掉不编译的选项。
2. /psp/flash-utils/DM36x/Common/src/devices.c
这个文件很重要，里面包括了所有的 CPU 内部接口的初始化，包括时钟，DDR2，串口……。要是换了 DDR2 那就得在这修改 DDR 的配置。因为这个文件没有定义 CPU 的主频和 DDR2 频率的配置，使用了默认的//Arm 297 DDR 243 MHZ，所以我再这个文件的头部定义了一个宏#define ARM432_DDR340_OSC24
3. /psp/flash-utils/DM36x/Common/src/devices.c
由 于 DEVICE_DDR2Init() 函 数 调 用 的 DDR_Get_Val() 编 译 时 报 错 ， 这 个 是 因 为DDR_Get_Val()函数里面的除法和求余函数跟编译器不匹配造成的。改发就是把算好的值代替掉 DDR_Get_Val()。
4./psp/flash-utils/DM36x/GNU/ubl/ubl.lds
这个链接文件里面有内存的起始地址和大小，NAND 的起始地址和大小的配置，这个根据板子的实际情况修改好。
完成上面的修改后就可以 make 了，生成的 ubl_DM36x_nand.bin 就是我们所要的 NAND 启动的 UBL 了。
二。串口启动
串口启动相关的代码在/psp/flash-utils/DM36x/GNU 下面的 sfh,sft,slh,slt。其中 sfh,sft,是一对，sfh(Serial Flasher host)是 PC 端的下载工具，sft(Serial Flasher target)是运行在 ARM 上的程序。编译 sfh 需要 sfl 文件，从 UART 启动时，RBL 先跟 sfh 通讯把 sft 下载到 IRAM 中运行，然后 sft 通过跟 sfh通讯，在 PC 端用命令行的方式把要下载的代码烧写到 NAND 上去。下面是使用的介绍：
Serial Flasher Usage
====================
More info can be found by running the utility with the '-h' option.
sfh_DM36x.exe -h1) Erase the NAND flash
sfh_DM36x.exe -nanderase
2) Flash the NAND with a UBL and u-boot image
sfh_DM36x.exe -nandflash <UBL binary file> <binary application file>
The entry point of the UBL is assumed to be 0x0100, but this can be changed by using the
-UBLStartAddr option. The entry point and load address of the application default to
0x81080000 (u-boot defaults). To change these values, use the -APPStartAddr and
-APPLoadAddr option.
NOTE: Currently, YOU MUST USE THE UBL BINARY CREATED BY THE UBL PROJECT
IN THIS PACKAGE. If you use any other UBL binary, the boot procedure will most likely fail.同样，slh 和 slt 也是一样的道理，只是他们是把代码下载到内部 RAM 或者 DDR2 上面去。
下面是使用介绍：
Serial Loader Usage
===================
More info can be found by running the utility with the '-h' option.
slh_DM36x.exe -h
1) Load a UBL or small UBL-like application to the DM36x IRAM
slh_DM36x.exe -load2IRAM <UBL binary file>
2) Load a larger image compiled to run at start of DDR space
slh_DM36x.exe -load2DDR <binary application file>
For the load to IRAM option, the file size is limited to 14KB, and the application assumes an entry
point address of 0x0100 (the smallest allowed). The entry point address canbe modified by using
the -startAddr command line option, with the address specified in hex.
For the load to DDR option, the file size is limited to 32MB, and the application assumes a load
address and entry point address of 0x80000000.
The entry point address can be altered by using the -startAddr command line option, as with the
-load2IRAM case. The load address can be altered from the default by using the -loadAddr
command line optionsfh_DM365x.exe 为 DVSDK 自带，所在位置如下图：

![DM368开发 -- 文件烧写[通俗易懂]](https://img-blog.csdn.net/20170620154642130)
由于使用 sfh_DM36x.exe 需要安装.Net Framework 2.0 或更高的版本，所以先安装.net 固件。
三、烧写 UBL 和 UBOOT
1.PC 端打开命令行工具， 把 sfh_DM36x.exe 和要烧写的 UBL， uboot 文件放在同一个目录下，
编写脚本 download.bat 然后使用命令
sfh_DM36x -nandflash ubl_DM36x_nand.bin u-boot.bin -p “COM1”
如 果 需 要 指 定 UBOOT 的 装 在 地 址 或 入 口 地 址 的 话 需 要 加 上 -APPStartAddr 和 -APPLoadAddr 指定。
![DM368开发 -- 文件烧写[通俗易懂]](https://img-blog.csdn.net/20170620154914430)
PS: 如上图所示插上短路帽则将板子设为串口启动，BTSET[2:0]=011 即NAND Boot mode
![DM368开发 -- 文件烧写[通俗易懂]](https://img-blog.csdn.net/20170620164621338)
烧写过程：
1、368 设备主板插上短路帽，超级终端连接设备，看到打印。
ps:此时 BTSET[2:0]=011 为串口模式
![DM368开发 -- 文件烧写[通俗易懂]](https://img-blog.csdn.net/20170620155118661)
此时断开超级终端
2.烧写文件目录找到 脚本，把里面的串口改为本地串口，运行该脚本，直到出现以下信息。
![DM368开发 -- 文件烧写[通俗易懂]](https://img-blog.csdn.net/20170620155252762)
关闭该运行窗口，再次运行该脚本，打开运行窗口，出现以下信息
![DM368开发 -- 文件烧写[通俗易懂]](https://img-blog.csdn.net/20170620155328366)
加载到 100%会自动关闭运行窗口
3.本地打开 tftp server 目录指向烧写文件目录
C:\Users\zslf\Desktop\shaoxie\sx\DM368\sx\u-boot 和 ubl 及烧写工具
4.打开虚拟机 ip 为 192.168.2.78(虚拟机要有文件系统)
5.关闭设备，拔掉短路帽，开启设备，会自动加载内核及文件系统，如下图
ps：此时 BTSET[2:0]=000 为 nand 启动模式
![DM368开发 -- 文件烧写[通俗易懂]](https://img-blog.csdn.net/20170620155416445)
直到出现进入 uboot 界面如下图
![DM368开发 -- 文件烧写[通俗易懂]](https://img-blog.csdn.net/20170620155502086)
6.在 uboot 下修改相关配置参数，依次设置以下指令，即完成板子烧写。
setenv bootargs dm365_imp.oper_mode=0 mem=48M console=ttyS0,115200n8 noinitrd rw
ubi.mtd=3 root=ubi0:rootfs rootfstype=ubifs video=davincifb:osd0=720x480x16,4050K ;setenv
bootcmd 'nand read 0x80700000 0x400000 0x400000;bootm 0x80700000';
saveenv
reset四、烧写说明
DM368用于小型化设备作为视频监控设备，本文主要说明的是怎样烧写DM368.
DM368采用的是NandFlash作为存储芯片，采用的是ubi文件系统.
DM368烧写分为三个步骤：通过串口烧写UBL和U-boot；u-boot下烧写uImage，主机下烧写ubi文件系统，修改启动参数；制作SD卡；
烧写UBL和U-boot
1.将UBL、u-boot.bin和download.bat批处理程序放在一个文件夹下，如下图所示；
![DM368开发 -- 文件烧写[通俗易懂]](https://img-blog.csdn.net/20170620160010713)
2.修改dwonload.bat中的串口设置
COM22修改为主机和板子相连的串口号(通过控制面板可以确认)；
![DM368开发 -- 文件烧写[通俗易懂]](https://img-blog.csdn.net/20170620160041179)
3.设置板子为串口启动，并加电；
串口启动时用跳线帽短接指定的两个电阻;
4.串口烧写
分两次双击download.bat(必须执行两次双击，每次执行都必须执行完毕)。完成后即烧写完了UBL和U-boot,断电后取下两个跳线帽；
以下宏定义指令文件所在位置：
/home/zslf/dm368/dvsdk_dm368_4_02_00_06/psp/u-boot-2010.12/include/configs#
vi davinci_dm365evm.h
在编译uboot的时候 设置 serverip、bootargs 等。
烧写内核和文件系统
第二部分烧写内核和文件系统实际上是自动化烧写完毕的。在这里分析下怎样实现的，主要是通过u-boot中bootcmd参数实现自动烧写uImage，nfs文件系统中软链接实现烧写ubi文件系统；
#define CONFIG_BOOTCOMMAND “tftp 0x80700000 uImage; nand erase 0x400000 0x400000; nand write 0x80700000 0x400000 0x400000;set bootcmd ‘ setenv bootcmd ‘ ‘;saveenv;nand read 0x80700000 0x400000 0x400000;bootm 0x80700000 ‘;set serverip 192.168.2.76;set ipaddr 192.168.2.194;saveenv;tftp 0x80700000 uImage;reset”
上述设置对应u-boot状态下bootcmd参数，含义是第一次上电后通过进入u-boot状态下通过tftp下载内核uIamge到内存0x80700000;修改再次启动的bootcmd参数；并将内核烧写到NandFlash中; ;修改再次启动的bootcmd参数;设置服务器ip(即主机IP)，板子的ip，再进行复位；
#define CONFIG_BOOTARGS \
“mem=60M console=ttyS0,115200n8 noinitrd rw eth=03:0E:EF:F2:FF:85 ip=192.168.2.194::192.168.2.1 nfsroot=192.168.2.78:/home/zslf/dm368/rootfs,nolock video=davincifb:osd0=720x480x16,4050K dm365_imp.oper_mode=0”
上述设置bootargs，实现nfs挂载，从而实现第一次进入nfs文件系统中后可以烧写ubi文件系统；
#define CONFIG_IPADDR 192.168.2.194
#define CONFIG_SERVERIP 192.168.2.76
#define CONFIG_GATEWAYIP 192.168.2.1
#define CONFIG_ETHADDR 0A:26:C4:9F:7D:19
设置服务ip,开发板地址，网关，mac地址；
在nfs文件系统的/etc/rc5.d/下有一个链接脚本，实现ubi文件系统的自动化烧写，如下图所示：
可以看出是一个软链接，真正的脚本在/zslf/write.sh
write.sh中 的内容是：
rootfs-php为ubifs文件系统，需要放在nfs根根文件系统的zslf目录下；
上述脚本即为烧写ubi文件系统，烧写完毕后重启系统；
![DM368开发 -- 文件烧写[通俗易懂]](https://img-blog.csdn.net/20170620160314621)
![DM368开发 -- 文件烧写[通俗易懂]](https://img-blog.csdn.net/20170620160335481)
有上面的原理可以得出第二阶段的烧写步骤：
1.配置tftpd服务器，准备uImage内核,如下图所示：
例如：设置tftpd服务器的服务目录为D:\tftp32pd_base\DM368
将内核放在服务目录下，如下图所示：
![DM368开发 -- 文件烧写[通俗易懂]](https://img-blog.csdn.net/20170620160403106)
2.配置虚拟机中nfs根文件系统和ubifs文件系统
主要是在/etc/export中设置，如下图所示
![DM368开发 -- 文件烧写[通俗易懂]](https://img-blog.csdn.net/20170620160547623)
![DM368开发 -- 文件烧写[通俗易懂]](https://img-blog.csdn.net/20170620160556576)
上述可知/home/zslf/dm368/rootfs为nfs根文件系统；ubi文件系统rootfs-php。
放在/home/zslf/dm368/rootfs/zslf/下
3.(取下短路帽，从Nand启动)，上电上电后，不要执行任何操作，系统自动烧写内核uImage和ubi文件系统，烧写完后，系统进行软复位，自动进入U-boot状态；
4.修改bootargs参数
修改bootargs参数，文件系统由nfs启动改为ubi文件系统启动；
修改如下：
setenv bootargs dm365_imp.oper_mode=0 mem=48M console=ttyS0,115200n8 noinitrd rw ubi.mtd=3 root=ubi0:rootfs rootfstype=ubifs video=davincifb:osd0=720x480x16,4050K ;setenv bootcmd ‘nand read 0x80700000 0x400000 0x400000;bootm 0x80700000’;
setenv bootcmd ‘nand read 0x80700000 0x400000 0x400000;bootm 0x80700000’
saveenv
reset;
五、制作SD卡
1.利用sd-format.sh脚本格式化sd卡，建立基本的SD卡；
2.拷贝/zslf文件系统；
至此DM368烧写完毕；
sd-format.sh 格式化脚本内容：
#!/bin/sh
e=""
m=""
n="xxxx"
while [ 1 ]
do
n="xxxx"
e=`fdisk -l | grep /dev/sdb1 | awk '{print $1}'`
if [ -z "$e" ];then
echo "####no sd ####"
else
echo "####have sd !####"
m=`df | grep media | awk '{print $1}'`
if [ -n "$m" ];then
umount $m
fi
#umount $e
echo "####start to format sd with ext3 filesystem!####"
mkfs.ext3 "$e"
echo "####end format sd!####"
#echo "copy zslf_app_dir"
mount $e /media/mmcblk0p1
#cp -a zslf /media/mmcblk0p1/
mkdir /media/mmcblk0p1/bak
mkdir /media/mmcblk0p1/video
umount $e
echo "##############zslf sd fomat and copy filesystem!
##########################"
echo "please remove sd!"
fi
sleep 5
if [ -n "$e" ];then
while [ -n "$n" ]
do
n=`fdisk -l | grep /dev/sdb1 | awk '{print $1}'`
sleep 5
done
fi
done六、其他烧写方式
