Booting the Kernel with Initramfs

Hi All,

I am trying to boot the kernel 3.28 with initramfs filesystem. For this, I have added the path for root file system in ‘General Setup->Initramfs source file’. But, I am unable to boot the kernel, since it stops with a message ‘Kernel Panic : unable to find root, try setting root="" to some valid device file’. But as far as I know, we don’t need to set the ‘root’ in bootargs when using the initramfs.

Can anyone please help me in this regard? Thanks in advance.
