windows下恢复更加简单，推荐windows系统下恢复。

To initialize your card under Windows, you can do the following:

1.Download and install Ubuntu's Win32DiskImager (also known as the win32-image-writer).
2.Download and install 7-zip compression software.

NOTE: WE SUGGEST THAT YOU USE THE LATEST VERSION OF 7-ZIP.

3.Download the SD card image you want to use listed below. These are the images that ship with the boards.
4.Download the HP Formatting tool from one of the following locations. These versions are 2.18. The previous version that you could download was 2.03 which supported FAT. FAT has been dropped from version 2.18.

• [HP Format Tool Ver 2.18 http://www.pcworld.com/downloads/file/fid,64963-page,1/description.html]
• [HP Format Tool Ver 2.18 http://files.extremeoverclocking.com/file.php?f=197]
• [HP Format Tool Ver 2.18 http://hp-usb-disk-storage-format-tool.software.informer.com/]
• [HP Format Tool Ver 2.0.6 http://www.4shared.com/rar/9mNWV4Vl/HP_USB_Disk_Storage_Format_Too.html]

5.Decompress the verification image file using 7-zip. 
6.Insert the SD card writer/reader into the Windows machine. 
7.Insert 4GB SD card into the reader/writer. 
8.If this a fresh card, one that has never been used, you can skip to step 11.
9.Run the HPFormatter tool and format the SD card for FAT or FAT32 in order to remove the second partition from the card.

         NOTE: In Windows 7 you will need to run this in administrator mode by right clicking and select "Run as Administrator"
               Under Windows XP, the format options are FAT32 and NTFS. Select FAT32.
               Under Windows 7, the format options are FAT and NTFS. Select FAT.
               You may see different operation for some reason where FAT32 or FAT may or not be there. You can select FAT or FAT32.

10.Close the HPFormatter tool when done.
11.Start the Win32DiskImager. 
12.Select the decompressed image file and correct SD card location. MAKE SURE YOU SELECT THE CORRECT LOCATION OF THE SD CARD.
13.Click on 'Write'. 
14.After the image writing is done, eject the SD card.

NOTE: If you are trying to reuse an SD card that has already been used under the above process, you will need to reformat the card to erase the second parttion. Otherwise Windows will only see the FAT32 partition
You must repeat step 9 to reuse the card.

To initialize your card under Linux, refer to the link to the Angstrom Demo Site. Follow the instructions found there, but use the images located on this site.
