MINI Board常见问题解答-Mini板开发环境使用

注：本说明是针对ICETEK-OMAP3530-MINI-V3的软件开发包，详细说明请参照ICETEK-OMAP3530-MINI-V3随附光盘中使用说明。这里我们将ICETEKWork/software/v3下的内容复制到ICETEKWork/projects下再进行如下操作。
1...如果已经做过启动卡,可将此卡插入读卡器后在Ubuntu中用文件浏览器删除卡上FAT32分区中除MLO文件,bootmode文件和u-boot00.bin，uImage00外所有文件,删除EXT3分区中所有文件及子目录.
2...打开project/xloader/include/configs/omap3530mini.h修改#define NAND_UBOOT_END 0x0160000为#define NAND_UBOOT_END 0x0260000；再将#define CONFIG_MMC 1注释掉，重新编译XLoader,生成新的x-load.bin.ift。
3...在Ubuntu中插入读卡器,使系统识别FAT32分区和EXT3分区并在桌面上显示相应图标(如果分区名称有不同,请在下面操作中根据相应的映射位置调整命令内容中相关部分)启动Ubuntu中终端,进行如下操作
     ...$ sync
     ...$cd ICETEKWork/projects/xloader/
     ...$sudo cp x-load.bin.ift /media/FAT32/（新生成的x-load.bin.ift）
     ...$cd ../busybox-1.12.2/
     ...$sudo cp -a _install/* /media/EXT3/
     ...$sudo mkdir -p /media/EXT3/work/fs
     ...$sudo cp _install/* /media/EXT3/work/fs/ -a
     ...$sync
4...卸载SD卡
5...在断电情况下,将SD卡插入Mini板,连接串口,在Windows中打开超级终端程序，接通电源启动ICETEK-OMAP3530-Mini系统，观察超级终端中的显示,在UBoot计数时按空格键停止.
6... 烧写XLoader到NandFlash：
      OMAP3 Miniboard # mw.b 80000000 ff 80000
      OMAP3 Miniboard # mmcinit
      OMAP3 Miniboard # fatload mmc 0:1 80000000 x-load.bin.ift
      reading x-load.bin.ift
      11412 bytes read
      OMAP3 Miniboard # nandecc hw
      OMAP3 Miniboard # nand erase 0 80000
      NAND erase: device 0 offset 0x0, size 0x80000
      Erasing at 0x60000 -- 100% complete.
      OK
      OMAP3 Miniboard # nand write 80000000 0 80000
      NAND write: device 0 offset 0x0, size 0x80000
      524288 bytes written: OK
7... 烧写UBoot到NandFlash：
      OMAP3 Miniboard # mw.b 80000000 ff 200000
      OMAP3 Miniboard # mmcinit
      OMAP3 Miniboard # fatload mmc 0:1 80000000 u-boot00.bin
      reading u-boot.bin
      212880 bytes read
      OMAP3 Miniboard # nandecc sw
      OMAP3 Miniboard # nand erase 80000 1e0000
      NAND erase: device 0 offset 0x80000, size 0x1e0000
      Erasing at 0x240000 -- 100% complete.
      OK
      OMAP3 Miniboard # nand write 80000000 80000 1e0000
      NAND write: device 0 offset 0x80000, size 0x1e0000
      1966080 bytes written: OK
8... 烧写Kernel到NandFlash：
      OMAP3 Miniboard # mw.b 80000000 ff 400000
      OMAP3 Miniboard # mmcinit
      OMAP3 Miniboard # fatload mmc 0:1 80000000 uImage00
      reading uImage
      1856668 bytes read
      OMAP3 Miniboard # nandecc sw
      OMAP3 Miniboard # nand erase 280000 400000
      NAND erase: device 0 offset 0x280000, size 0x400000
      Erasing at 0x660000 -- 100% complete.
      OK
      OMAP3 Miniboard # nand write 80000000 280000 400000
      NAND write: device 0 offset 0x280000, size 0x400000
      4194304 bytes written: OK
      OMAP3 Miniboard # nand erase 680000 7980000
      NAND erase: device 0 offset 0x680000, size 0x7980000
      Skipping bad block at  xxxxxxxx
      Erasing at 0x7fe0000 -- 100% complete.
      OK
      OMAP3 Miniboard # setenv bootcmd 'nand read 80200000 280000 400000;bootm 80200000'
      OMAP3 Miniboard # setenv bootargs console=ttyS2,115200n8 console=ttyS0 noinitrd root=/dev/mmcblk0p2 rootfstype=ext3 rw rootdelay=3 nohz=off
      OMAP3 Miniboard # save
      OMAP3 Miniboard # boot
9...烧写文件系统到NandFlash：(在系统启动后提示Please press Enter to activate this console.此时按一下回车键进入控制台)
      [MiniBoard]# mkdir /mnt
      [MiniBoard]# mkdir /mnt/nand
      [MiniBoard]# mount -t jffs2 /dev/mtdblock4 /mnt/nand
      [MiniBoard]# cd /mnt/nand
      [MiniBoard]# cp -a /work/fs/* .
      [MiniBoard]# sync
      [MiniBoard]# cd /
      [MiniBoard]# umount /mnt/nand
10...从NandFlash启动系统 给ICETEK-OMAP3530-Mini系统重新加电,停止UBoot程序运行,进入UBoot的命令行状态
      OMAP3 Miniboard # setenv bootargs 'console=ttyS2,115200N8 console=ttyS0 noinitrd root=/dev/mtdblock4 rw rootfstype=jffs2'
      OMAP3 Miniboard # save
11...断电，去掉SD卡，上电重新启动系统。
