The USB-powered BeagleBoard is a low-cost, fan-less single board computer that unleashes laptop-like performance and expandability without the bulk, expense, or noise of typical desktop machines.
The image below is for BeagleBoard Rev C5 and later. BeagleBoard C5 starting shipping 7/17/2011.
This board has a new DDR+NAND memory device. The old device was discontinued.
This forced us to move to a new device which has 256MB DDR and 512MB NAND. A new image is required. Follow the instructions below
to create a SD canrd and reflash the NAND in the event it has been written over or corrupted.
- There is a new UBoot that is required for the Rev C5 board to handle the new memory device. - As a result of this change, all of the images currently running on C4 versions will need to be modified to handle the new memory. - This is a 2.6.32 Kernel
BeagleBoard Rev C4/C5 Reflashing Procedure
To initialize your card under Windows, you can do the following:
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.<br/> 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 FAT 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.
15. Insert the new SD card into the board.
16. Connect a USB self power HUB to the C5 USB host port.
17. Connect a keyboard and mouse to the HUB.
18. Connect a DVI-D compatible monitor to the DVI-D connector..
19. Hold the user button down and apply power or hit reset after power has been supplied.
20. Hold the button for 10 seconds and then release it.
21. The SW will automatically flash the NAND.
22. When completed, remove the SD card and reset the board.
23. The board will boot to a Linux desktop.
24. You will be able to naviagte the desktop using the keyboard and mouse.

To view the PCB files, a free viewer can be downloaded from Cadence. You can use this to make measurements, check dimension on the PCB, and look at each layer to analyze the routing used.
You can download the file at Allegro Viewer
NOTE: The only change is this revision is the OMAP processor revision. No expected impact on operation. This revision uses the same schematic and PCB as revision C5.
NOTE: This version still uses the Rev C4 PCB. No changes were made to the PCB.
