Kernel panic on dvevm6467 board when using NFS

This error has come up many times in the past on the forum, usually the 'Kernel panic - not syncing: No init found.  Try passing init= option to kernel.' means that either your filesystem is corrupted (such as symbolic links broken by using a plain cp to copy it or not being extracted as root) or missing.

Simon said:

The board seems to recognise that there is an NFS server there but seems to ignore the rootpath.

The NFS server itself seems to be working as you suggest, though it is probably taking into account the rootpath or you would be getting some other error, the rootpath= having nothing after it in the kernel boot log is ok.

Thanks, I removed the file structure on the host and reinstalled and now the board loads up fine.

I do have another problem now after compiling and trying to run the demo apps

I can compile them fine but have trouble when trying to load the CMEM module

root@davincitest:/# cd opt/dvsdk/dm6467/
root@davincitest:/opt/dvsdk/dm6467# ./loadmodules.sh
CMEMK Error: CMEM phys_start (0x87800000) overlaps kernel (0x80000000 -> 0x90000

The demo apps won't load due to the CMEM module not being loaded.

Any help would be most appreciated.

Your CMEM driver isn't loading b/c of the reported overlap in memory map.  You need to resolve this memory map issue.

Thanks easy.

Hi,

im user of Davinci DM6467 but i have some problem to boot my EVM: kernel panic, i followed the option recommanded in this forum but the problem is against here. the nfs start well but i think there are a problem below.

here, the part of getting started guide: Please tell me if im wrong: i followed:

4) Perform the following commands to create a copy of the target file system with permissions set for writing to the shared area as useracct. Substitute your user name for useracct. If you installed in a location other than /opt/mv_pro_5.0, use your location in the cp command.

host $ cp -a /opt/mv_pro_5.0/montavista/pro/devkit/arm/v5t_le/target/* .

here I did: cp -a /opt/mv_pro_5.0/montavista/pro/devkit/arm/v5t_le/target/ /home/thierno/workdir/filesys/   Its correct to copy?

host $ chown -R useracct opt
here i did: chown -R thierno /home/thierno/workdir/filesys/    Its correct?

5) Still as root, edit the /etc/exports file on the host Linux workstation (not the exports file on the target filesystem) using a text editor like gedit, for example:

host $ gedit /etc/exports 
no change

Add the following line for exporting the filesys area, substituting your user name for useracct. Use the full path from root; ~ may not work for exports on all file systems. By editing the exports file you are effectively sharing the folder so that other devices (such as the EVM) can mount it.

/home/useracct/workdir/filesys *(rw,no_root_squash,no_all_squash,sync)
no change

thanks
Thierno

there is a small error in the line: cp
it is:

cp -a /opt/mv_pro_5.0/montavista/pro/devkit/arm/v5t_le/target/ /home/thierno/workdir/filesys

ITs correct for copy ?

thanks

thierno

thierno,

the copy looks fine.  However, chown command should be executed on    /home/thierno/workdir/filesys/opt   directory.  I have not tried what would happen if you change ownership of the entire target filesystem (normally has root ownership).  Can you delete filesys directory, recopy the filesystem and only change ownership on this directory? 

Also, there is still the possibility that your kernel can be corrupt (assuming it is compatible for now); you may want to reflash your kernel (uImage)

Juan, thank you again
but the directory / home / thierno / workdir / filesys / opt does not exist.
the directory / home / thierno / workdir / filesys  him exist.
therefore it is chown: chown -R thierno  / home / thierno / workdir / filesys?
or else: chown-R thierno / home / thierno / opt / mv_pro ...? where the /opt/mv_pro is the installation directory of the target linux software.
not well detailed in the guide

Thierno

we definitely want the filesys directory and not the other....

Can you copy your bootlog to a post similar the the person that started this thread?  also a copy of your /etc/exports file may help...

hi,

here  the gedit of my /etc/export file

According to  your boot-log, your kernel appears to be an older MV pro 4 (based on 2.6.10 kernel)

Linux version 2.6.10_mvl401-davinci_evm

However, your copy command above suggests your file system is based on MV Pro 5 kernel... This could certainly explain the issue.  Both kernel and file-system must come from same DVSDK release.  Please upgrade your kernel to MV Pro 5 and this should help resolve the issue.

hi,
I still have not received my score card DM6467T, I always use the DM6467 card (This DM has already been used by others).
I re-installed all soft (mvl5 and dvsdk from ti.com website) but I still have the same problem (kernel panic ...)
but when I look at the boot log, I see that version remains mvl4.
how to update the mlv55 in the EVM by serial link from the host linux (where i have all sources). please.
Thank you in advance
best regards
