GuruPlug Plus Gets a New OS - Redux, part 2 (uboot/kernel)

Flashing a new uboot & kernel
(this continues from the previous post)
Hit any key to stop the autoboot.  Since they factory uboot and kernel images have incorrect arcNumbers, flashing one and not the other will cause the kernel to not boot.  Because of this we're going to go ahead and flash both.

In order to do this, you'll need:

• a working tftp server (in Fedora 'yum install tftp-server' and make sure xinetd is reloaded and running).  I'm using a tftp server because the GuruPlug is picky about USB keys.
• either no firewall or configuration settings for tftp (you can drop the firewall settings temporarily with 'sudo server iptables stop' and when you're finished 'sudo service iptables start'
• A new uboot image.  I choose this one mostly for convenience.  In Fedora, this should be copied to /var/lib/tftpboot.
• A new kernel image.  I choose this one mostly for convenience.  The only thing that I have found that I don't care for in this image is the kernel timestamps, but I can live with that for now.  In Fedora, this should be copied to /var/lib/tftpboot.

First thing we will do is set the serverip and ipaddr variables.  Serverip is the IP address of the tftp server, and ipaddr is the GuruPlug address.  They need to be on the same subnet.

Now we're ready to load the uboot image and flash it to nand memory.

At this point you'll want to reboot by using the reset command.  There are a couple things to be aware of at this point.  These are completely normal:  You'll get a CRC error for your environment and your MAC addresses are likely lost for your ethernet interfaces and you'll have to fix that.  We'll do that on this first boot.

If your intent was only to upgrade uboot and the kernel, I have good new for you - you're mostly done.  If you want to keep Debian, just login with root/nosoup4u and install the kernel modules that were in the same directory as the kernel (untar them to /).
