Hi

Looking to update the kernal on my DP (currently on 3.0)

Is it as easy as downloading the latest script and running it i.e.sudo ./README-DREAM-UPDATE.sh 3.4.4

It boot parameters or other configs need to be changed what are they

Thanks in advance

        echo "****************************************************************"
        echo " update your bootcmd to load dream-$KVer-uImage"
        echo " or create a link from /boot/dream-$KVer-uImage to /boot/uImage"

Curiosity, not a compliant (how could anyone complain about your kernel builds) but what is the current state of the latest ones?
They seem to be partly there - but Kernel headers are missing...

I created a link to /boot/uImage, but it is still booting the old kernel (3.0.4). Is there a bootarg I need to set to point to /boot/uImage

Hi

I'd love to get some help here.

The images on the dreamplug websites do not install uImage in /boot, they are on a separate 100MB partition. The script here creates a uImage in /boot. Does this script work with the globalscale images? If so how do I point to /boot in setenv bootargs?
If not, what image does this script work with? and is there a howto anywhere?

Images referred to above are

Have you tried "mount /dev/sda1 /boot" 
and then "sudo ./README-DREAM-UPDATE.sh 3.4.4" ?

This should put the uImage in the right spot

Good Luck

BigBear, many thanks that was exactly what I needed to know.  I've now updated to 3.4.6 without a hitch.

I have tried to update the kernel using your script, but I'm missing flash manipulation tools:

Code:
# ./UPDATE-SHEEVA-KERNEL.sh                                     
missing /usr/sbin/flash_eraseall                                               
missing /usr/sbin/flash_erase
#

I'm running an Angstrom distribution, and I can't find those tools in the repo Sad

Also I'm trying to update from an old Guruplug running a 2.6.32.2 kernel from the internal flash. I have set mainline linux yes and arcNumber 2659. I think this is enough for the kernel to boot, right?

I have manually updated the kernel to your 3.4.7 build and everything is working perfect!

I couldn't get the script to work, but thanks anyway!

Time to upgrade my old Angstrom installation to a new ArchLinux Arm distro  Wink
