TFTP server in the host (Mandrake 9.2 ) is configured like this:

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

}

The environment variables are:

$ printenv

bootargs=root=/dev/mtdblock2 devfs=mount console=ttyS0,115200

bootcmd=bootm 40000

bootdelay=3

baudrate=115200

stderr=serial

filesize=4a6

netmask=255.255.0.0

ipaddr=172.16.16.220

serverip=172.16.16.70

TFTP can work fine in 1.0.0, but be affected by network environment. What's kind of the server do you use for the host configuration, DHCP, BOOTP ?

Could you show the console messages ? Also I want to know your environment variables. That is shown by "printenv" command.

Hi all,

We're using u-boot 1.0.0 to boot Linux on a Lubbock based platform. We've been able to boot Linux from RAM, with JFFS2 and nfsroot too. But we've a problem with tftp.

We know that the tftp server works because we've tested it with other clients. But with tftp in u-boot we're only able to transfer little files (1, 2 Kb)..

Which can be the problem?? Newer versions work fine??

Thanks in advance

Regards,

Sonia
