virtualbox ubuntu and tftp

You create directory on host and after boot board you try run application from this directory, I am right?

If you must run application on your board you must copy it on board or mount directory with application, e.g. on NFS.

Hi Oliver,

Make sure that your copied location (directory) and accessing from the target are same.

I have some questions here,

Which file system you are using? NFS/SD/JFFS2?

Does tftp server is running on your virtual machine (ubuntu)? Do you copy the helloworld application to tftp folder?

Many thanks for your prompt reply. You
gave me the inspiration not to take a timeout.

What I basically not understand is the
way how the target can find the “path” to the folder where the wanted
application is located. What do I have to mount?

What I did until now is the following:

./setup.sh

iptables –F

windows 7 firewall all to off

File system  nfs.

For the SD-card I was using

host
$ sudo ${EZSDK}/bin/mksdboot.sh --device /dev/sdb --sdk ${EZSDK}” as shown in
the manuals

On host xinet is used:

Hello Anil

Thanks for your answer.

This command I've tried on target yesterday, too.

I do "ifconfig eth0 192.168.0.154 netmask 255.255.255.0" on target

The exact command I've set on target is "tftp -g 192.168.0.154 -r hello.txt". The ip is the what I get with windows command ipconfig at the host.

For that I get "tftp: timeout".

Regards

Oliver

Hi Oliver,

Can you answer to my first question in my previous post?

ipaddress should be get from ubuntu not from windows, because your tftp server is running on ubuntu not on windows.

Another way is you can install tftp server in windows and you can tftp from there.

I think you missed out the Network bridge connection in virtualbox.

Hello Anil

helloworld is "helloworld*" after make. I'm just using the examples out of the manual "DM814x AM387x EZ 5.02 Software Developers Guide"

Oliver

Hi Oliver,

Can you try building with static keyword?

linux-host$ arm-arago-linux-gnueabi-gcc -static -o helloworld helloworld.c

Hi Anil

nothing changed. The file is just 10 times larger.

I've changed the network ip of ubuntu to 192.168.0.155 with netmask 255.255.255.0.

by using command tftp -g 192.168.0.155 -r helloworld I get tftp timeout

Regards

Oliver

Hi Oliver,

Can try these commands in you host machine (ubuntu)? You should call these from any where except /tftpboot

linux-host$ sudo tftp 192.168.0.155

tftp > bin

tftp > get helloworld

tftp > quit

linux-host$

Regards

AnilKumar

Hi Anil

the server works:

host$ sudo tftp 192.168.0.155

tftp> bin

tftp> get helloworld

Received 5686 bytes in 0.1 seconds

tftp> quit

Regards

Oliver

Hello

I got same problem.

How did you fix it???

chshin@chshin-desktop:~$ sudo tftp 192.168.0.189

Hi Shin,

Have you followed the exact steps specified in "DM814x AM387x EZ5.02Software Developers Guide"?

Can you try this command on board?

$ tftp -g <tftp server ip> -r helloworld

Hi Shin,

Your ethernet port is not up.

Have you connected ethernet cable to the board? If yes, can you try this command

$ ifconfig eth0 up

And provide the ifconfig details.
