Avance 01/03/12 Upgrade U-Boot

Avance

On Atmel.no buildroot You can find a pre-built image of a SD card which will upgrade your Network Gateway more or less automatically. This image is tested and known to work with the following cards:

• No-name MMC 32 MB (supplied with Nokia phones)
• TwinMOS MMC 32MB
• No-name HP SD 64MB (supplied with a camera)
• Kingston SD 128 MB (stk1000 & NGW100)
• SanDisk SD 128 MB (stk1000)
• SanDisk SD 512 MB (ngw100)
• SanDisk SD 1.0 GB (ngw100)
• SanDisk SD 2.0 GB (ngw100)
• Kingston Elite Pro SD 256 MB
• Viking SD Interworks 256 MB
• TwinMOS Ultra-X SD 512 MB
• Transcend microSD 2GB (stk1000)
• Platinum 1GB SD (NGW100)

Not working cards:

• extreMEmory SD 2GB EM premium (works after upgrade to u-boot 1.3)
• no Name 32 MB MMC Card (NGW100)

Assuming that sdb is the device of your SD card, write the image with dd on your Linux workstation with:

~# sudo dd if=ngw_fw_upgrade.img of=/dev/sdb 

If you are using Windows, please refer to writing images with dd on Windows.

If you are using Linux and wish to format your SD card at any stage, you can use "cfdisk" from the command line or install "gparted" into your graphical interface (possibilities include installation va rpm, yum, apt-get etc).

Note that the image distributed is a complete SD card image, this means to write the image correctly onto the SD card, the specified device should be sdb not sdb1 (or sda not sda1) etc.

This is important. You want to end up having dd write a complete 32mb image into a new partition of 32mb. If you specify sda1 instead when you should have sda, you might end up with a successful write by dd but it won't have set up the partitions correctly and this means the following UBoot commands will fail.
