I would like to update my GP+ kernel to the newest ones using the update script, but I don't know how to do it. Let me explain a bit more...

I'm running ArchLinux. Arch on GPs comes with a 3.1 kernel, but I am using 3.7.9 kernel downloaded from xilka. Until now I have been manually installing kernels from uboot via tftpboot/nand erase/nand write. So my GP+ reads the kernel from the NAND, and then the filesystem is mounted from the microSD card.

I was going to test manually updating to the latest 3.13 kernel, but now I see that not only the kernel image is needed, also the device tree must be flashed. And I don't know where do I need to flash it or how. So I think now it's time to do things the right way: updating the system using the update script instead of manually messing with uboot.

How can I do it? Do I need to format the internal flash in a special way and mount it? What boot command/params should I set it uboot? Is there a step by step tutorial anywhere?

Unfortunately I don't have a GP+ to test on, so here's how you probably want to proceed.

The kernel image is built with a device-tree backward compatibility mode,  If you look at the script you will see that it "merges" the zImage with the appropriate .dtb file.  When the zImage is loaded it looks for a .dtb that is appended to it's tail.  The .dtb describes the hardware and everything should work.

That merged zImage/.dtb can be in either system flash or on removable media (if your u-boot supports that).  If you look at the section that handles the original sheevaplug you should be able to duplicate that functionality for a GP+.

Please get back to me with patches if you decide to proceed with enhancing the UPDATE-KERNEL.sh script.

Working OK again today. Grabbed the last 3.11 kernel and will stick with that seems more robust on my sheevaplug.

Anyone else having problems with http://www.xilka.com ?
Not at the moment. I've just browsed down through the 3.13.3 kernel listing with no problem.

Many links just redirect to www.appfail.com  Huh
Odd place to go.  The xilka site isn't accessed over https.  Well, it can be, but the certificate is issued for "*.scaleengine.net", which is where xilka.com lives, but isn't of any use for it.
Seems odd to go to the expense of a valid wildcard certificate (from Comodo) when the subject name isn't actually going to be used.

Has this site been compromised?  Have the kernels it hosts been compromised too?  All rather unnerving....

I desperately need to downgrade from 3.13.2 due to ehci usb disconnect problems, but can't get an old kernel, not do I trust that site anymore even if I could...

Has anyone successfully gotten the CuBox wifi to function as an access point?

The OLPC XO Serial Adapter Kit $25
works on my DreamPlug at half the price.
The only proviso is that you must connect Black, Red, Green to Ground, Rx, Tx (respectively) rather than the way you would if you were connecting to an XO.
No soldering involved.  It comes with the correct connector.
It's very small and much more convenient than the expensive one provided by Globalscale.

You could also consider Adafruit's FTDI Friend:
 http://www.adafruit.com/products/284
but you'd have to also get the correct connector- one of the "picoblade" products from AMP.   
Available here:
http://www.digikey.com/product-detail/en/0510210400/WM1722-ND/242844
But you'd have to figure out how to connect the wires- I haven't figured it out yet although haven't tried very hard because the XO adapter works very well.

I've been struggling with this problem as well.
I've got the following installed and working on my DreamPlug model: 003-DS2001:
wget http://http.debian.net/debian/pool/main/u/u-boot/u-boot_2012.04.01-2_armel.deb
wget http://http.debian.net/debian/dists/wheezy/main/installer-armel/current/images/kirkwood/netboot/marvell/dreamplug/uImage
wget http://http.debian.net/debian/dists/wheezy/main/installer-armel/current/images/kirkwood/netboot/marvell/dreamplug/uInitrd

It has the 8787 wifi chipset.

As suggested in a previous post, I tried:
root@shirati:/etc/apt# iw dev mlan0 interface add uap0 type __ap
command failed: No such device (-19)
root@shirati:/etc/apt#

but as you can see, I'm missing something.  The "__ap" looks suspicious.
I'd be grateful for any guidance.
cheers,alex

I went ahead and opened a kernel bug at https://bugzilla.kernel.org/show_bug.cgi?id=70191 to try to investigate the instabilities.
