Hi,

 

 

I've got a quick question regarding the kernel upgrade instructions on a Cubietruck that runs on Igor's Debian image.

 

 

Let me mention first that the system boots from my Cubietruck's NAND. However, the root partition and the /home partition are both installed on some SSD.

 

 

I've followed the instructions about the kernel upgrade (3.4.106-cubieboard to 3.19.6-cubietruck) in order to be able to use the proper shutdown feature - as detailed on http://www.igorpecovnik.com/2013/12/24/cubietruck-debian-wheezy-sd-card-image/.

 

I.e. I installed the various *.deb packages which were contained in the *.tar archive via `dpkg -i`. Then I ran the steps as described on "Optional steps if you have your system on NAND" and rebooted. 

 

Apparently, the kernel in use is still my trusty 3.4.106-cubieboard. The new one (3.19.6) hasn't been loaded.

 

Am I missing a step here? Would I need to edit the boot loader (grub?) or would I have to uninstall the old kernel in order to be able to use the new one?

 

 

 

Any hint would be greatly appreciated.

The most important problem here is that NAND is not supported in kernel different from 3.4.x ... If this is ok, than download latest system (4.1.6).

 

You will need to boot from SD card, than change boot script parameter from root=/dev/mmcblk0p1 to /dev/sda, copy kernel files  /lib/modules/xxxxxxxxxx from SD card to SDA. Boot from hard drive.

 

Add /dev/mmcblk0p1 to your /etc/fstab and mount under /boot

 

Done.

How can I change Mainline kernel to Legacy (for Cubietruck i need linux-image-sun7i ? ) to HW acceleration support?

Ok, i think, simpler reinstall on SD Card image with Legacy Kernel.
