Hello,
I am trying to boot the kernel with a ramdisk image built from arago filesystem. I have tried booting this default (git) Linux image "uImage"( made using davinci_dm644x_defconfig) with sample arago filesystem images found from the arago website and successfully booted. I can see login menu and everything works well.
But when I create this ramdisk by following the typical methods for preparing ramdisk I have an error message after Linux kernel mounts arago filesystem image.
I get the following message:
VFS: Mounted root (ext2 filesystem) on device 1:0.
Freeing init memory: 136K ----> I believe these messages show that an arago filesystem image is mounted.
But then I get the following message:
Kernel panic - not syncing: No init found. Try passing init= option to kernel.
----->And this message shows that the init file is not found. I think after mounting image the kernel looks for /etc/inittab and starts executing it. This file is present in the filesystem. Though the kernel does not accept it.
I also tried to explicitly provide the file by its path via the bootargs environment variable init=/etc/inittab
Still I get the same problem.
I also tried providing init=/linuxrc. But it was of no use.
Can anyone tell me what is the problem?
Following is the output on the console. Is there anything wrong with my ramdisk image
Following are my bootargs:

I dont understand the last few lines. Are they partitions or wat?
Please provide your suggestions. Thank you.
