Hey,
It does matter :), i had the problem too, you''ll have to use the nfs-user-server. My /etc/exports is as follows:

/160GB/ris/nfsroot 192.168.2.0/255.255.255.0(rw,no_root_squash,sync)

Kind Regards,
Daan Biere

Hello all,

I suspect now the problem is on my linux machine hosting the NFS serv.
Is there a significant difference between an NFS share being served in user mode or kernel mode? I just learned of these different modes reading up on some unrelated documentation. I can mount my NFS share on other systems just fine, but i suspect that doesn't guarantee the board will be able to boot off it. I am running CentOS 3.6, which came with an nfs service, which is what I'm using for this. Are all NFS services created equal and does the mode (user or kernel) matter for this task?

Thanks,
Andy

Hello all,

I'm trying to boot off an NFS share as laid out in the OSK Users
guide so I can begin my software development process. My buidling of the system with the approrpiate makefiles has all gone seamlessly. I am attempting to boot from the NFS share on my linux machine, which I've demonstrated is possible from a neighboring machine. The error is as follows:

Kernel panic: No init found.  Try passing init= option to kernel.

I have tried putting an "init=/bin/sh" argument into the bootargs string, but that hasn't solved the problem. Does anyone else have a bootargs string for an NFS share that they have used succesfully? Here is the string I am currently using for refference:

console=ttyS0,115200n8 noinitrd rw ip=dhcp root=/dev/nfs nfsroot=192.168.1.101:/home/usr/projects/filesys,nolock mem=30M init=/bin/sh

Thanks for your help,
Andy

Andy, this is a working NFS boot string for my 1611 H2 with today's git kernel:

mem=32M console=ttyS0,115200n8 noinitrd root=/dev/nfs rw nfsroot=172.30.2.32:/home/markh/omap/nfsroot ip=dhcp

Cheers,

Mark.

Hello all,

I'm slated to develop an application that sends and recieves UDP
packets over the ethernet port of the OMAP5912 EVM board from spectrum digital. Does anyone have a decent document pertaining to this process, and better yet, a working application that could help guide my development there-in? Any help you can offer will be greatly appreciated.
