##2013-9-13 Support DNW and Fastboot

#fastboot
step1: fastboot # 开发板
step2: fastboot flash bootloader tiny210v2-uboot.bin ＃PC
step3: fastboot flash kernel /work/tftpboot/uImage_softecc ＃PC
step4: fastboot flash system /work/tftpboot/rootfs_qtopia_qt4.img ＃PC
step5: nand read 21000000 400000 500000 # 开发板
step6: bootm # 开发板

    #dnw  v1.0
dnw-linux : https://github.com/changbindu/dnw-linux
other : 如果要实现从SD卡启动时候直接启动DNW菜单，在include/configs/tiny210.h中打开CONFIG_DNW_MENU_AUTORUN宏就可以实现了。这里默认不启动。关于dnw的使用，请参考别处介绍。

2013-8-31 Support Yaffs2 for slc NandFlash write

    step1: tftp rootfs_qtopia_qt4.img 
    step2: nand erase e00000 2000000
    step3: nand write.yaffs 21000000 e00000 $filesize
    step4: setenv machid 0xd8a
    step5: tftp uImage_softecc
step6: bootm

说明：

  • rootfs_qtopia_qt4.img是我精简过的yaffs2镜像文件，所以2000000大小要根据镜像大小改变

目前情况：可以实现16bit ECC校验，校验某处不准确，现在内核还不能启动起来。

2013-07-27 支持tftp下载内核nfs挂载根文件系统

	step1: setenv machid 0xd8a
	step2: setenv bootargs root=/dev/nfs nfsroot=192.168.1.229:/work/rootfs_dir/nfs_rootfs/rootfs_qtopia_qt4 ip=192.168.1.230:192.168.1.229:192.168.1.1:255.255.255.0::eth0:off console=ttySAC0,115200 mem=512M
	step3: tftp uImage_308
	step4: bootm

说明:

  • 0xd8a是tiny210v2内核用的机器码
  • bootargs中的路径和ip与你实际情况更改
  • rootfs_qtopia_qt4是rootfs_qtopia_qt4-20130222.tar.gz通过命令行解压得来的
  • uImage_308是友善光盘中的3.08内核make uImage得来的

2013-07-23 修改oobsize大小

2013-07-20 用"BL1"代替“spl”，使得BL1和u-boot代码脱离，便于移植(环境变量在SD卡中，请插SD卡)

2013-06-27 Nand/SD卡启动，u-boot.bin/spl二合一。

2013-06-26 开始移植 适用于tiny210v2 NandFlash:K9GAG08U0F
