Hi folks,I am a beginner with the DaVinci and in this forum.We are using a UdWorks DM8168 Rev. 05B platform with software DVRRDK_01_09_00_19. Our development platform is a Ubuntu 10.04 running in Virtualbox.At the moment we do the first steps with this device.I compiled the Linux kernel and the dvr_rdk with success.Now we want to load the kernel via Tftp and the root file systen via NFS.Loading the kernel with Tftp works, the kernel starts up but getting the jffs2 rootfile system fails.We have a NFS server (nfs-kernel-server) running on our host. The access to this server works fine.I have tested this with an client from an external machine. The hosts firewall is turned off. The client has access to the nfs root. But loading the jffs2 while startup up the DM8168 fails.Do You have any idea what our prblem can be ?Here is the log, the Uboot settings, hosts.deny, hosts.allow and exports:

Did a bit of reading on the "Connection refused" error (https://help.ubuntu.com/community/SettingUpNFSHowTo). Might indeed be a portmapper problem. Check "/etc/default/portmap" for binding to loopback, eg -l option. However that does not explain why other machines can connect to the NFS server. Maybe a router between your target and server causing problems? Yeah, grasping at straws here.
Comparing your bootloag against another bootlog (http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/t/158046.aspx). A few differences. His has IPV6, random MAC address and just 1 PHY. Probably not important? The "Link is Up" message is missing from your bootlog. When you are running from flash do you get that same message? Perhaps try a ridiculously long rootdelay. Appears the JFFS2 bootarg okay with NFS bootargs. A red herring I think.
Hi Norman,Thanks for watching my problem. Nice community here.I checked /etc/default/portmap. The line with loopback is commented.I also did try a long rootdelay (60 seconds).Using the bootarg "rootfstype=jffs2" has no effect.
And last bur not least, I used a new kernel. I tested Kernel 04.04.00.01 with the same results.
Tomorrow, in the office, I will try to setup another PC and run Ubuntu without Virtualbox.I will post my results.
The mention of Ubuntu and VirtualBox reminded me about posts about "bridged adapter" mode in your virtual machine. Quickly mentioned here:
http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/100/t/121814.aspx#435754
Hi folks,I found the problem. Running Ubuntu in Virtualbox avoids contact to the NFS server.I made a setup for Ubuntu 10.10 standalone and now I can boot the root file system.For me it is not easy to understand, because I have access to the NFS server form an external client (Windows PC) also via Virtualbox. And the network adapter in Virtualbox is configured "Bridge"Has anybody a solution for using Virtualbox with NFS ?
Hi Holger,
I'm using the same board with a 2.6.34 kernel and boot it via nfs. Virtual host has Ubuntu 10.04. with EZSDK + toolchain + tftp + nfs + targetfs image. I was using VirtualBox for the first time but when its screen resolution brakes a little I started using vmware. No special adjustments were made to them. Networking mode - bridge. Real host - Ubuntu 11.10.
Below my uboot config allowing a number of different boot modes (mmc, nfs, tftp and combinations). Perhaps it will be useful for you.
To choose a special boot mode once I write `run bootorig` to run original boot from sd or `run boot_tftp_nfs` (I'm using it and it is default boot mode now) or other command.
Uboot config: 1715.uboot.txt
Good to see that problem is resolved.
I observed the same if I connect my Virtualbox to wireless network, I am able to access the NFS if I use the wired network. But I haven't investigated why this is happened?

Hi Michael,
Thanks for Your answer and Your bootsettings.
At the moment, I use Windows XP with VirtualBox. Next I will test VMWare.
I have good experience with VMWare in the past.
I will post the results.
Hi folks,
I have tested Ubuntu10.04 running in VMWare with Windows 7.
NFS boot works perfect.
Thank You to all the folks here in this forum for the support !
