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

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, Midhun Agnihotram
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

Hi Midhun.

Some tips that might shed light on your problem :
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.
