###关于 这是网蜂webee210的uboot程序,下面是其主菜单:
##### Boot for Webee210 Main Menu #####
[1] Webee210 USE_USB_DOWN Download mode
[2] Webee210 USE_SD_DOWN Download mode
[q] quit to Command line

###编译
@ make distclean
@ make webee210_config
@ make
###烧uboot到你的sd卡
1.查看你的SD:
在ubuntu下,通过下面的命令查看你的sd卡:
sudo fdisk -l
下面是在ubuntu下打印的信息:
Partition table entries are not in disk order
Disk /dev/mmcblk0: 7969 MB, 7969177600 bytes
221 heads, 20 sectors/track, 3521 cylinders, total 15564800 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
/dev/mmcblk0p1 8192 15564799 7778304 b W95 FAT32
/dev/mmcblk0 是你的SD设备,确保他是FAT32格式的.
2.下载uboot到你的SD卡:
# cd ~/webee210-uboot
# sudo dd iflag=dsync oflag=dsync if=webee210-uboot.bin of=/dev/mmcblk0 seek=1
# sync
注意:项目目录下有一个sd-burn.sh的脚本,请在执行前打开来看看里面的文件名和sd卡的路径是否和你的电脑相同.
###UBOOT 菜单
uboot有两级菜单,这是第一级.可以选择usb烧录或是SD卡烧录,或是退出到命令行模式.

[q] Return to Menu
#################################################
Enter your selection (╭￣3￣)╭ :
在这个模式下,你可以烧录linux内核和文件系统到你的nand flash.
不过你需要先对你的SD做一些准备工作:
(1).查看你的SD卡
在ubuntu下:
# sudo du
# fdisk -l
Disk /dev/mmcblk0: 7969 MB, 7969177600 bytes
4 heads, 16 sectors/track, 243200 cylinders, total 15564800 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
/dev/mmcblk0p2 43008 247807 102400 83 Linux
/dev/mmcblk0p3 247808 15564799 7658496 83 Linux
(2).对你的SD卡进行分区:
先对已经存在的的分区进行卸载:
# umount /dev/mmcblk0p2
# umount /dev/mmcblk0p3
用fdisk进行分区:
# fdisk /dev/mmcblk0
Command (m for help):
输入 p 打印SD信息:
Command (m for help): p
Disk /dev/mmcblk0: 7969 MB, 7969177600 bytes
4 heads, 16 sectors/track, 243200 cylinders, total 15564800 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
/dev/mmcblk0p2 43008 247807 102400 83 Linux
/dev/mmcblk0p3 247808 15564799 7658496 83 Linux
输入 d 删除分区 /dev/mmcblk0p2,/dev/mmcblk0p3:
Command (m for help): d
Partition number (1-4): 2
Command (m for help): d
Selected partition 3
输入 n 切割新分区 :
Command (m for help): n
Partition type:
p primary (0 primary, 0 extended, 4 free)
e extended
Select (default p):
选1,意味着分区1:
Partition number (1-4, default 1): 1
为了给uboot留空间,我们从4380开始,大小为50M,存放linux内核,即uImage:
First sector (2048-15564799, default 2048): 4380
Last sector, +sectors or +size{K,M,G} (4380-15564799, default 15564799): +50M
Command (m for help): p
Disk /dev/mmcblk0: 7969 MB, 7969177600 bytes
4 heads, 16 sectors/track, 243200 cylinders, total 15564800 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
/dev/mmcblk0p1 4380 106779 51200 83 Linux
同样的方式,我们来切割分区2.分区2的开始为分区1的结束blocks+1,即:106779+1.大小取决于你的yaffs2 file.
Command (m for help): n
Partition type:
p primary (1 primary, 0 extended, 3 free)
e extended
Select (default p): p
Partition number (1-4, default 2): 2
First sector (2048-15564799, default 2048): 106780
Disk /dev/mmcblk0: 7969 MB, 7969177600 bytes
4 heads, 16 sectors/track, 243200 cylinders, total 15564800 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
/dev/mmcblk0p1 4380 106779 51200 83 Linux
/dev/mmcblk0p2 106780 4301083 2097152 83 Linux
输入w,让上面的配置生效:
Command (m for help): w
(3).格式化你的分区:
将分区格式化为 FAT32:
# mkfs.vfat /dev/mmcblk0p1
mkfs.vfat 3.0.14 (23 Jan 2023)
# mkfs.vfat /dev/mmcblk0p2
mkfs.vfat 3.0.14 (23 Jan 2023)
(4)将文件直接复制到你的SD卡
cp linux 内核到 /dev/mmcblk0p1,文件系统到 /dev/mmcblk0p2.
注意 : 确保你的 uImage 文件名为 uImage,yaffsz文件系统名为 webee_yaffs2_img
