###USAGE @ make distclean @ make webee210_config @ make
###DOWNLOAD
1.cat your sd card device:
sudo fdisk -l
2.you may see this in ubuntu:
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 is your sd device. make sure your sd format is FAT32
3.downlaod uboot to your sd card:
donwlaod the webee210-uboot.bin to the first block of your sd.
# cd ~/webee210v2
# sudo dd iflag=dsync oflag=dsync if=webee210-uboot.bin of=/dev/mmcblk0 seek=1
# sync

In linux,your can get the dnw tool from there webee-dnw
2.the SD download mode
##### Boot for Webee210 Main Menu #####
##### Webee210 SD download mode #####
[1] Download Linux Kernel (filename:uImage) to Nand Flash from SD
[2] Download YAFFS image (filename:webee_yaffs2_img) to Nand Flash from SD

[4] Format the Nand Flash -(°□°!)
[q] Return to Menu
#################################################
Enter your selection (╭￣3￣)╭ :
In this mode,you can download the linux kernel and the yaffs2 file-system to the nand flash by SD card. But you should do something to your SD card first:
(1).Cat Your SD
here is my SD card on ubuntu:
# 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

/dev/mmcblk0p3 247808 15564799 7658496 83 Linux
(2).Parted your SD card:
we should ummout the dev that we going to delete:
# umount /dev/mmcblk0p2
# umount /dev/mmcblk0p3
here we start:
# fdisk /dev/mmcblk0
Command (m for help):
type p to get info
Command (m for help): p
Disk /dev/mmcblk0: 7969 MB, 7969177600 bytes

/dev/mmcblk0p3 247808 15564799 7658496 83 Linux
type d to delete /dev/mmcblk0p2,/dev/mmcblk0p3:
Command (m for help): d
Partition number (1-4): 2
Command (m for help): d
Selected partition 3
type n to get the new part we want:
Command (m for help): n
Partition type:
p primary (0 primary, 0 extended, 4 free)
e extended
Select (default p):
we should choose p ,and then 1 to get part 1:
Partition number (1-4, default 1): 1
the default block is start from 2048,in order to make room for uboot,wo start from 4380.and the size is 50MB.We are going to put the linux kernel here:
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

Device Boot Start End Blocks Id System
/dev/mmcblk0p1 4380 106779 51200 83 Linux
using the same way,wo just get the part 2,which we going to put the yaffs2 file.the start block of part 2 should be the end of part1 plus 1,and that is:106779+1.the size is depend on your 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

/dev/mmcblk0p2 106780 4301083 2097152 83 Linux
the make it work,we should type w,and we will get the Partition we want
Command (m for help): w
(3).Format Your Partition:
format the Partition of SD into 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)Put the file into SD
just copy the uImage file to /dev/mmcblk0p1,and the yaffs2 file to /dev/mmcblk0p2.
warning: make sure the filename of your uImage file is uImage,and yaffs2 file is webee_yaffs2_img
