一. 刷机初识

  1.1. 什么是刷机

    a. 刷机就是通过各种手段把相应镜像烧录到设备中,让设备可以运行起来。常见的刷机如:安卓刷机,QT刷机

  1.2. S5PV210刷机镜像

    1.2.1. 刷安卓所需要的镜像

      a. uboot镜像: uboot.bin

      b. linux kernel镜像:zImage-android

      c. android rom镜像: x210.img

    1.2.2. 刷QT4.8 所需要的镜像

      a. uboot镜像: uboot.bin

      b. linux kernel镜像: zImage-qt

      c. rootfs镜像:rootfs_qt4.ext3

  1.3. 刷机过程使用到的工具

    1.3.1. 烧录uboot所需要的工具

      1.3.1. 使用SD卡烧录ubbot

        a. 方式一:在windows中用刷卡工具去制作启动SD卡,刷卡工具 x210_Fusing_Tool

        b. 方式二:在linux中用dd命令烧录uboot

      1.3.1. 使用USB烧录uboot

        a. 方式一:在window下使用dnw软件进行下载uboot.bin

        b. 方式二:在linux下使用dnw工具进行下载uboot.bin

    1.3.2. uboot启动后烧录全部镜像到flash中

      1.3.1. 使用fastboot烧录

        1.3.1.1. 使用fastboot烧录android4.0.4镜像

          a. fastboot flash bootloader android4.0\uboot.bin        烧uboot
          b. fastboot flash kernel android4.0\zImage-android     烧linux kernel
          c. fastboot flash system android4.0\x210.img              烧android rom

        1.3.1.2. 使用fastboot烧录linux+QT镜像

          a. fastboot flash bootloader linuxQT\uboot.bin      烧uboot

          b. fastboot flash kernel linuxQT\zImage-qt      烧linux kernel
          c. fastboot flash system linuxQT\rootfs_qt4.ext3     烧rootfs

二. 烧录实践

  2.1. 烧录uboot

    2.1.1. 使用x210_Fusing_Tool烧录uboot

      a. 最好使用管理员启动软件

      b. 烧录效果如下:

  2.2. 在linux中用dd命令烧录uboot

    2.2.1. 将uboot_sd_fusing相关文件放到uboot源码下

    2.2.1. 制作过程如下

root@ubuntu:~/x210_porting/uboot-jiuding/sd_fusing# ls
C110-EVT1-mkbl1.c Makefile sd_fusing2.sh
c110.signedBL1_bin sd_fdisk.c sd_fusing.sh
root@ubuntu:~/x210_porting/uboot-jiuding/sd_fusing# make
gcc -o mkbl1 C110-EVT1-mkbl1.c
gcc -o sd_fdisk sd_fdisk.c
root@ubuntu:~/x210_porting/uboot-jiuding/sd_fusing# ./sd_fusing.sh /dev/sdb

Eject SD card and insert it again.
root@ubuntu:~/x210_porting/uboot-jiuding/sd_fusing#

  2.3. 在window下使用dnw烧录

    2.3.1. 刷机分2步:

      a. 第一步刷x210_usb.bin,地址是0xd0020010;

      b. 第二步刷uboot.bin,刷机地址是0x23e00000

S5PV210刷机-LMLPHP

  2.4. linux 使用dnw工具烧录uboot

    2.4.1. 源码包获取,编译和安装

    2.4.2. 成功连接后现象:

      a. Windows下设备管理器没了;

      b. ls /dev/secbulk0 设备节点自动出现

    2.4.3. dnw进行下载uboot.bin

      a. dnw -a 0xd0020010 x210_usb.bin
      b. dnw -a 0x23e00000 uboot.bin

三. 使用fastboot烧录镜像到flash

  3.1. 在uboot中对flash进行分区

    3.1.1. 分区命令fdisk -c 0  

x210 #
x210 # fdisk -c
fdisk is completed partion # size(MB) block start # block count partition_Id
0x83
0x83
0x83
0x83
x210 #

  3.2. uboot的参数中bootcmd和bootargs 

x210 # print
baudrate=
ethaddr=::5c::0a:5b
gatewayip=192.168.1.1
ipaddr=192.168.1.20
netmask=255.255.255.0
serverip=192.168.1.141
bootdelay=
bootcmd=tftp 0x30008000 zImage;bootm 0x30008000
bootargs=root=/dev/nfs nfsroot=192.168.1.141:/root/x210_porting/rootfs/rootfs ip=192.168.1.20:192.168.1.141:192.168.1.1: Environment size: / bytes
x210 # set bootcmd 'movi read kernel 30008000; bootm 30008000'
x210 # set bootargs console=ttySAC2, root=/dev/mmcblk0p2 rw init=/linuxrc rootfstype=ext3
x210 # saveenv
Saving Environment to SMDK bootable device...
done
x210 # print
baudrate=
ethaddr=::5c::0a:5b
gatewayip=192.168.1.1
ipaddr=192.168.1.20
netmask=255.255.255.0
serverip=192.168.1.141
bootdelay=
bootcmd=movi read kernel ; bootm
bootargs=console=ttySAC2, root=/dev/mmcblk0p2 rw init=/linuxrc rootfstype=ext3 Environment size: / bytes
x210 #

  3.3. uboot进入fastboot

x210 # fastboot
[Partition table on MoviNAND]
ptn name='bootloader' start=0x0 len=N/A (use hard-coded info. (cmd: movi))
ptn name='kernel' start=N/A len=N/A (use hard-coded info. (cmd: movi))
ptn name='ramdisk' start=N/A len=0x300000(~3072KB) (use hard-coded info. (cmd: movi))
ptn name='config' start=0xAECC00 len=0x1028DC00(~264759KB)
ptn name='system' start=0x10D7A800 len=0x1028DC00(~264759KB)
ptn name='cache' start=0x21008400 len=0x65F7000(~104412KB)
ptn name='userdata' start=0x275FF400 len=0xC0C6FC00(~3158463KB)

  3.4. windown fastboot软件使用

    3.4.1. 相关命令使用

      3.4.1.1. fastboot devices 命令用来查看当前连接的设备。(我们开发板看到的是:SMDKC110-01)
