[U-Boot-Users] TFTP with U-Boot

[Midhun Agnihotram]

Hi All,

  I am still not able to do a tftp. I have checked and rechecked my
server settings according to the DULG manual.

**  I am using a Fedora Core 6 as my host. My /etc/xinetd.d/tftp is as below:

service tftp
{
        disable = no
        socket_type             = dgram
        protocol                = udp
        wait                    = yes
        user                    = root
        server                  = /usr/sbin/in.tftpd
        server_args             = -s /tftpboot
        per_source              = 11
        cps                     = 100 2
        flags                   = IPv4
}

** When I start xinetd :

# /etc/init.d/xinetd start
Starting xinetd:                                           [  OK  ]

** The netstat gives ;
# netstat -a | grep tftp
udp        0      0 *:tftp                      *:*

** The /etc/services file also contains the correct the port number too.

tftp            69/tcp
tftp            69/udp

** cAll seems to be fine. But still the tftp does not work.

** When I connect the ethernet cable of the target to the host, the

Jun  6 12:17:50 kernel: e100: eth0: e100_watchdog: link up, 10Mbps, half-duplex



        Can anybody please let me know what could be the problem? Has
anybody used Fedora as their host for U-boot? Is it the problem with
the host or the target?


Thanks a lot,

Hi Midhun.

The tftp client seems to be timing out.

Some tips that might shed light on your problem :

1. For testing purposes, ensure that you only have the host and the
target board on the network, either via a crossed ethernet cable or a
hub.

2. As a quick test, run /usr/sbin/in.tftpd "by hand", ie not via the
init.d scripts and see if that makes a difference.

3. Triple-check your portmapper setup. Invariably, tftp is clamped in
the hosts.allow/deny framework by default.

4. Use wire-shark (formerly ethereal) to snoop on the wire and see
what's going on. This is probably your best bet.

Cheers,
Robin

If you have not done this already, make sure your server is serving the 
file to itself and another computer before trying to use u-boot to get 
the file.

a. On your linux server, do "tftp localhost" and get the target file.

b. On a separate machine, do "tftp 222.222.101.117" (your server_ip per 
below) and get the target file.

You also have a link status "Jun  6 12:17:50 kernel: e100: eth0: 
e100_watchdog: link up, 10Mbps, half-duplex".  Is 10Mbps half duplex 
correct for your link?  If not, you are likely having an autonegotiation 
problem - 10/half is the "other side is stupid, I gotta guess" 
configuration.  If this is wrong, you probably have a PHY configuration 
problem (likely the MII connection to the PHY - H/W and/or S/W).

I couldn't tftp with -s, at least for me. Please try.

try to deactivate SELinux and firewall (for testing).
My problems with tftp was related to a misconfigured SELinux.
By the way, if you find a SELinux-setting that works, please inform me.
