Exporting a Shared File System for Target Access in dm6446??????

With out knowing what errors or what steps you have performed already, all i can do is recommend http://processors.wiki.ti.com/index.php/Category:DaVinci

Which PDF, what steps you took, sections of the code you used and how you hooked things up may help resolve this issue,

TMS320DM6446 DVEVM v2.0
Getting Started Guide
host $ cp -a /opt/mv_pro_5.0/montavista/pro/devkit/arm/v5t_le/target/* : in this command,I must ignor "*"
host $ chown -R <useracct> opt: in this command says "There is no opt directory"

/home/<useracct>/workdir/filesys *(rw,no_root_squash,no_all_squash,sync): in this command,must add "etc/exports" at the end.
and it says: syntax error

host $ /usr/sbin/exportfs -av : for this one says "There is no exprot.d directory"..!!!!!!!!!!!!

host $ /sbin/service nfs restart: it says "service not recognized"

host $ /etc/init.d/iptables status
host $ /etc/init.d/iptables stop : for these ones says "there is no file or directory"

Ok, I read some of the setup and where it says Host $ try it with out that.  Part of 4.1.1 Command Prompts in This Guide is a lot unclear if you type " Host $ " for the command or not, from what experience I remember, most commands I didn't have to from a command prompt window.

At this point, it looks like ( from me at least ) what I can do is point you to http://linux.davincidsp.com
TI DaVinci Software Updates: http://www.ti.com/dvevmupdates

Also for recommend reading ( for me to read as well ) http://www.nslu2-linux.org/wiki/HowTo/SetUpPDCWithSamba

I do not say try it, just look over the Linux code and skim over what they are doing in case this fits along the lines of what you want to accomplish.

Once that is resolved ( and all needed services started ) it seemed you would want to set the Ethernet as on.  If i found the correct getting started PDF, " Note: The default U-Boot bootargs definition sets "ip=off", which disables the Ethernet connection "  http://www.ti.com/lit/ug/sprue66e/sprue66e.pdf

Also Flash boot with NFS file system (Section A.4.3) Also see Section A.4, Alternate Boot Methods ( recommended reading even if you do not intend to now )
