How to update the kernel image

To follow some tutorials on this site is required to install a new linux kernel image on your FOX Board G20. this article illustrates how to do that on a running board without removing the microSD card.

Get the access to the command line using a DPI interface or a SSH terminal session.

Mount the first FA16 partition typing:

debarm:~# mount /dev/mmcblk0p1 /mnt

Save a copy of the old image:

debarm:~# cd /mnt
debarm:/mnt# ls -al                                                             
total 3647                                                                      
drwxr-xr-x  2 root root   16384 Jan  1 01:00 .                                  
drwxr-xr-x 23 root root     568 Jan 13  2010 ..                                 
-rwxr-xr-x  1 root root     231 Jan  7  2010 foxg20-script.bin                  
-rwxr-xr-x  1 root root 3713696 Jan  1  1980 uimage                             
debarm:/mnt# 
debarm:/mnt# cp uimage uimage_old

Now get and uncompress the latest kernel image from the repository:

debarm:/mnt# 
debarm:/mnt# wget http://foxg20.acmesystems.it/download/debian_kernel_20100322.tgz
debarm:/mnt# tar xvzf debian_kernel_20100322.tgz
uimage
foxg20-script.bin

Now sync the changes on the microSD and reboot the board:

debarm:/mnt# sync
debarm:/mnt# reboot
