While booting linux on ARM based platform, I suffered enough and linux boot hasn't get going across panic......It's panic, which has stopped me...and I am not sure what's wrong and where. I am comparatively a newbie so google is helping me a lot !
Found an interesting article....hope it gives me some clues to move further....
What's an initial RAM disk?
The initial RAM disk (initrd) is an initial root file system that is mounted prior to when the real root file system is available. The initrd is bound to the kernel and loaded as part of the kernel boot procedure. The kernel then mounts this initrd as part of the two-stage boot process to load the modules to make the real file systems available and get at the real root file system.
The initrd contains a minimal set of directories and executables to achieve this, such as the insmod tool to install kernel modules into the kernel.
In the case of desktop or server Linux systems, the initrd is a transient file system. Its lifetime is short, only serving as a bridge to the real root file system. In embedded systems with no mutable storage, the initrd is the permanent root file system. This article explores both of these contexts.
