SBR600 Project Release 0.3


Hello Everybody,

Today, I released my SBR600 project version 0.3. I tested my last package several times and it worked successfully. It was actually an extension of my project version 0.2. Not only I changed version 0.2 to works with any kernel, including the new kernels, but also I merged my package with primary kernel package. So, when the Arch is ARM, it installs my package (RPM-based kernel for ARM) and when the Arch is something else, it works as a regular kernel installation. In other words, I could create a RPM-based kernel for ARM which was my project. I built my package on both ARM and Primary architecture to make sure that it works.
This is the output of "ll" command before installing of last version of kernel in my ARM board:

[root@fedora-arm khosro]# ll /boot/
total 7824
drwxr-xr-x 2 root root 4096 Apr 14 2011 grub
-rw-r--r-- 1 root root 2071652 Apr 14 2011 initramfs-2.6.32.img
-rw-r--r-- 1 root root 2071652 Apr 14 2011 initramfs.img

-rw-r--r-- 1 root root 1909048 Apr 14 2011 uImage.bin

And here is the output of "ll" command after installing my package which shows the new files: (pay attention to link files):

[root@fedora-arm ~]# ll /boot/
total 11900
drwxr-xr-x 2 root root 4096 Apr 14 2011 grub
-rw-r--r-- 1 root root 2071652 Apr 14 2011 initramfs-2.6.32.img
-rw-r--r-- 2 root root 2070985 Dec 31 1999 initramfs-2.6.35.img

-rw-r--r-- 2 root root 2003236 Apr 21 2011 uImage.bin

The 2.6.35 is the last version of kernel up to this point that I wrote this blog.
Now, this is the output of booting my ARM board with new kernel (also, pay attention to “uname” command after logging to system):
