NFS boot of DM365 IPNC-MT5

can you break into u-boot and see if you can ping your host from your target?  You should since TFTP appears to have worked, which means your firewall on your host should be properly set as well.  One other thing to check is your hosts NFS service; make sure is is enabled and that the directory specified by $(rootpath) in you settings above match your host's /etc/exports file settings.

Hello,

I am able to ping to my nfs server.

Following are the settings in my /etc/exports file.

/home/users/Kalpesh/IpNetCam/ipnc/target/filesys_ipnc   *(rw,sync,no_root_squash)

I think there is not any problem with /etc/exports settings..

I dont know why it is saying "IP-Config: No network devices available".

Is there any problem with my kernel uImage or the problem in my bootargs????

Regards,

Chintan Choksi 

your fisrt post had the following

   DM365 IPNC :>setenv rootpath /home/users/Kalpesh/IpNetCam/ipnc/target/filesys_ip

and your las post stated that your /etc/exports file has

   /home/users/Kalpesh/IpNetCam/ipnc/target/filesys_ipnc   *(rw,sync,no_root_squash)

first directory path has an additional 'IpNetCam' directory not found on /etc/exports.  If this is true, this could be the source of the issue.

No this is not the source of the issue.

I have given correct path in the bootargs and also in the /etc/exports.

I think the issue is because of kernel searches for NFS file system before initalization of eth0 driver at boot up.

You can observe in my first post.

If i am worng somewhere,please correct me.

Please guide me. how can i make sure that ethernet driver initializes first at the bootup. 

It appears you were able to TFTP, so it seems like the network support in u-boot is ok.  Therefore, this sounds like it is eithet a problem with the host's NFS service or the Linux kernel.  What flavor of Linux are you using for your host OS?  Also, which uImage are you running, the pre-built one that came with IPNC, the pre-built one that came with our DVSDK, or one you built yourself?  I am attaching a working boot log on my DM365 EVM (not an IPNC kit) so you can compare to your bootlog (you may want to remove the 'quiet' from your bootargs to see all the log).

     I got an same problem with chintan choksi, I runing the pre-built uImage from IPNC,

this is the default params which can work well with ramdisk boot:

DM365 IPNC :>print

       I have use DM355, DM365 board before but never used Appro program, so maybe somewhere I made an mistake, please let me know if anything can help me, thanks

looks like you are using static ips (as opposed to dynamic IPs) in your bootargs (e.g. ip=dhcp for dynamic ips).  I have not tried the short-hand form, but the folloing worked for me on our dm365 EVM

bootargs=console=ttyS0,115200n8 noinitrd rw ip=192.168.1.41:192.168.1.40:192.168.1.1:255.255.255.0:::off root=/dev/nfs nfsroot=192.168.1.40:/home/user/dm365/dvsdk_2_10_00_18/filesys,nolock mem=76M

where 192.168.1.41 = evm ip,

          192.168.1.40 = host ip

          192.168.1.1 = gateway

          255.255.255.0 = netmask

Juan:

      I have test that before, and have the same problem as mentioned, and I use the same params on 365EVM board and got passed with an good NFS mounted. so I want to know why I can "ping" and "tftp" well in U-boot which means network device work well, but when I run uImage and mount NFS got an message like "IP-Config: No network devices available"? dose this mean network card haven't start?

Hello All,

Finally I found where the problem exists.......

Ya its in kernel configuration 

kernel was  configuring  CONFIG_TI_DAVINCI_EMAC as 'm' . It means it was configuring EMAC driver as file system module.So kernel  was searching for FileSystem in the network   before loading the EMAC driver. I have configure it to 'y'. It means it will be preconfigured in the kernel.

Now my kernel boots properly.

I guess this is the problem with DM365 IPNC only because i have checked kernel configuration file for Dm365 EVM. In that case CONFIG_TI_DAVINCI_EMAC as 'y'

Regards,

Chintan Choksi

Hi,

    Do you know how to specify the bootargs of IPNC to configure the framebuffer and the display stand?

    Is it like the evm's configuration

bootargs=console=ttyS0,115200n8 noinitrd rw ip=dhcp root=/dev/nfs nfsroot=192.168.198.1:/opt/dmsw/MVL401_rootfs,nolock mem=116M video=davincifb:vid0=0:vid1=0:osd0=720x576x16,2025K davinci_enc_mngr.ch0_output=COMPOSITE davinci_enc_mngr.ch0_mode=ntsc

?

   Thanks!

Hello All

We are facing the same issue with IPNC i.e we are not able to boot using tftp and NFS file system. 

Did it work by just changing the EMAC driver option? It didnt work for us by just changing the EMAC driver option. 

Could you share your bootargs so that we can cross verify with your bootargs? Our bootargs are as below.

setenv bootdelay 4

setenv baudrate 115200

setenv bootfile uImage_dm365

setenv videostd NTSC

setenv serverip 192.168.1.1

setenv ipaddr 192.168.1.2

setenv netmask 255.255.255.0

setenv ethaddr 00:0C:0C:A0:02:BC

setenv nfshost 192.168.1.1

setenv gatewayip 192.168.1.3

setenv rootpath /mnt/DaVinci/workdir/filesys

setenv bootcmd 'nboot 0x80700000 0 0x200000; bootm'

setenv bootargs 'mem=60M console=ttyS1,115200n8 root=/dev/nfs rw noinitrd ip=192.168.1.2 eth=00:0C:0C:A0:02:BC nfsroot=192.168.1.1:/mnt/DaVinci/workdir/filesys,nolock'

saveenv

printenv

We get the same error every time we try to boot

Kernel panic not syncing VFS 

Please suggest what could be the issue?

With Regards

Pravin 

Pravin,

Have you modified the uImage on the NAND after you changed the EMAC driver config to "y" instead of "m" in kernel configuration file? Can you please share your log during boot-up?

Ideally, once you use debug kernel config, it should work fine. Ofcourse you have to use the newly created uImage instead of the one already burnt on IPNC.

Regards,

Anshuman

Hi Anshuman

We followed these steps  in the ti-davinci/linux - --- --- folder

i) make distclean

ii) make davinci_dm365_ipnc_defconfig_dbg

iii) make uImage

The resultant uImage we are transfering to /tftpboot folder and given the above mentioned bootargs.

We always get kernel panic message "unable to sync VFS".

Please let me know in case you need any more details.

With Regards

Pravin Angolkar

Pravin,

Your bootargs show that you are trying to boot from NAND and not from TFTP. So even if you place your uImage in /tftpboot, it is not going to help. You are not using your newly generated uImage to boot.

Either change bootargs to boot from TFTP or program the uImage on NAND and boot from NAND.

regards,

Anshuman

Hi All,

I also cound not boot from nfs on DM365 ipnc-MT5.

According to the Posted by chintan choksi on 25 Sep 2009 12:42 AM , I try to modify lsp_ipnc_dm36x_1.0.0.tgz, configuring  CONFIG_TI_DAVINCI_EMAC to 'y', I also modify File Systems according to seeddsp's dm365 EVM. Then booting as follow,

Thanks!

1. At first, you can boot IPNC from cramfs, and test you NFS，

     $mount -t nfs -o nolock 192.168.1.240:/opt/dm365ipnc/fage/rdmnts /opt/test

    Only test success, you can do next.

2. You must set IP address through bootcmd, not use dhcp.

   like this:

      setenv bootargs console=ttyS1,115200n8 noinitrd rw ip=92.168.1.21 gw=192.168.1.xx eth=00:0c:0c:A0:02:b5 root=/dev/nfs nfsroot=192.168.1.240:/opt/dm365ipnc/fage/rdmnts,nolock mem=60M

Try to do it.

Looking at your bootlog, it is clear that the network device is not initialized. Please ensure that you have built the defconfig of the kernel (dm365_ipnc_defconfig_dbg), which enables the ethernet as built-in driver instead of module.

Which version of IPNC software are you using?

Regards,

Anshuman

Anshuman，

  NFS configuration is ok.

  I really don't know how to built the defconfig of the kernel. how ?

  Version of IPNC software,  is it mean DVSDK? I use dvsdk_dm365_setuplinux_2_10_01_18.bin.

Please guide me.

Regards,

swinter

Hi,

You are using IPNC-MT5 and hence you would have got IPNC software which has version number for it. For example IPNC ver 1.0, ver 1.1, ver 1.5, ver 1.9 etc...

Anyways, specifically for the problem of building the debug version, if you are using IPNC software, follow the below steps:

1. Go <IPNC_REF_DESIGN_FOLDER>/ipnc/ti_davinci/arch/arm/configs/

2. # mv davinci_dm365_ipnc_defconfig_dbg davinci_dm365_ipnc_defconfig

3. Go <IPNC_REF_DESIGN_FOLDER>/ipnc

4. Do complete build steps for lsp (# make lspall)

5. Copy the uImage generated and use it for TFTP or NAND boot

Regards,

Anshuman

PS: Please mark this post as verified, if you think it has answered your question. Thanks.

Thank you Anshuman,

You help me a lot, but I still could not boot from nfs.

Sotfware version is DM365PrivatePackage-1.0-Setup.exe,  Open_src_IPNC_DM365_1.0.0.tgz,  lsp_ipnc_dm36x_1.0.0.tgz, ipnc_app_dm365_open_1.0.0.tgz .

///////////////////////////////////////NFS File system installing/////////////////////////////////

(1)I do it according DM365PrivatePackage\Docs\Users_Guide_IPNC_DM365.pdf(section 2.4), show as picture 1,  so the nfs rootpath is /opt/dm365ipnc/fage/filesys.

 (2) Another way i do it is like that, so the another nfs rootpath is /opt/dm365ipnc/nfs_target.

# cd /opt/dm365ipnc/
# mkdir -p nfs_target
# cd nfs_target
# cp /opt/dm365ipnc/montavista/pro/devkit/arm/v5t_le/target/* .

Then I config /etc/exports as follow,

/opt/nfs *(rw,no_root_squash,no_all_squash,sync)
/opt/dm365ipnc/nfs *(rw,no_root_squash,no_all_squash,sync)
/opt/dm365ipnc/nfs_target *(rw,no_root_squash,no_all_squash,sync)
/opt/dm365ipnc/fage/rdmnt *(rw,no_root_squash,no_all_squash,sync)

It is like EMAC has initializted through boot up, but failed. Now I want to know how to install nfs file system on linux host?

Please guide me. What should I do? What is wrong with my steps?

Regards,

swinter.

I am sorry, I check my configuration,  the bootarg is problem. IP is wrong. I use follow string, then I could boot from nfs.

setenv bootargs console=ttyS1,115200n8 noinitrd rw ip=192.168.1.21 gw=192.168.1.1 eth=00:0c:0c:A0:02:b5 root=/dev/nfs nfsroot=192.168.1.240:/opt/dm365ipnc/nfs_target,nolock mem=60M

but i still want to know how to instll nfs file system, because I can not boot from nfs when using root path /opt/dm365ipnc/fage/filesys.

Thanks,

Have you copied the filesys folder from the mounted cramfs to any other folder and then used it as NFS root filesystem? I usually mount the cramfs to a local directory say /mnt/mmc and then copy the contents from /mnt/mmc to say /opt/dm365ipnc/fage/filesys, then use it for exporting the network file system on NFS server.

hi please follow the link

http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/100/p/52262/190925.aspx#190925

with subject DM365 IPNC setup issues.

the same NFS problem has been solved and discussed in the post dated 28-06-10.

one more thing would like to addthe IP address in ur PC should have a IP similar domain with the camera.

for example your PC IP is 192.168.17.195 and camera ip id 192.168.1.168 the in TCP IP properties add a temporary ip for ur pc might be 192.168.1.40.

for your reference below is my boot env.

Hi all,
 I use DM365 IPNC-MT5, meeting issues when boot from nfs.
 By the way, I really don't know SW version, maybe is ver1.0.

///////////////////////////////////////NFS File system installing/////////////////////////////////

(1) I do it according DM365PrivatePackage\Docs\Users_Guide_IPNC_DM365.pdf(section 2.4), so the nfs rootpath is /opt/dm365ipnc/rootfs/filesys.

#cd /opt/dm365ipnc/rootfs
#mkdir filesys
#mount -o loop -t cramfs cramfsimage_ipnc_dm365_1.0.0 filesys

(2) Another way i do it is copying the mount dir as follow, so the another nfs rootpath is /opt/dm365ipnc/rootfs/copyfilesys.

# cd /opt/dm365ipnc/rootfs
# mkdir copyfilesys
# cd copyfilesys
# cp cp -a /opt/dm365ipnc/rootfs/filesys/* .

But I get some warning here,
root@vresearch:/opt/dm365ipnc/rootfs/copyfilesys# cp -a /opt/dm365ipnc/rootfs/filesys/* .
cp: will not create hard link `./etc/dhcpc' to directory `./dev/pts'

cp: will not create hard link `./var/run/usb' to directory `./dev/pts'
root@vresearch:/opt/dm365ipnc/rootfs/copyfilesys#

Then I config /etc/exports as follow,
/opt/nfs *(rw,no_root_squash,no_all_squash,sync)
/opt/dm365ipnc/nfs *(rw,no_root_squash,no_all_squash,sync)
/opt/dm365ipnc/nfs_target *(rw,no_root_squash,no_all_squash,sync)
/opt/dm365ipnc/rootfs/filesys *(rw,no_root_squash,no_all_squash,sync)
/opt/dm365ipnc/rootfs/copyfilesys *(rw,no_root_squash,no_all_squash,sync)

# exportfs -rv

 I could not boot from nfs using rootpath /opt/dm365ipnc/rootfs/filesys(I even could not mount it on linux host), I copy filesystem from mount, then meet a lot of errors(see NFS boot log), as I see it, booting from nfs using /opt/dm365ipnc/rootfs/copyfilesys should autostart applications normally, How do deal with it? Please guide me.

Regards,

swinter

Hi swinter,

have you referred the discussions made by me while i was doing the same.

kindly follow this link below

http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/100/p/52262/190925.aspx#190925

you will find all the problems related to NFS on IPNC and the solutions too are discissed.

Oh yes,

The problem is just solved yesterday,  installing the filesystem is like this,

a. Copy cramfsImage_ipnc_dm36x_xxx to /home/<useracct>/ in your Linux desktop 
    b. Go to working directory and create a new directory to mount file system
            #cd <Filesystem Mount Directory>
            #mkdir filesys
            #mkdir rdmnt2
    c. Mount the file system using following command:
            #mount -t cramfs -o loop cramfsImage_ipnc_dm36x_xxx rdmnt2/
            #cd rdmnt2
            #tar -cf  - . | tar -C ../filesys/ -xpf –

And then make sysall the dvsdk &app, built the dbg kernel and boot from nfs, all is ok!
