[U-Boot-Users] tftp problem

[Martinez Sonia]

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

Why are you posting the very same message twice  from  two  different
mail addresses?

Please NEVER do this again!!!!

What happens then? Is there an error mesaage or what? Did you try  to
debug the problem?

Ummm... did you try it out? If yes, what was the result? If not, why not???

[U-Boot-Users] TFTP PROBLEM

[Masami Komiya]

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.

[U-Boot-Users] TFTP PROBLEM

[Sonia Martinez]

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

  ethaddr=00:08:33:33:00:01

  stdin=serial

  stdout=serial

  stderr=serial

  filesize=4a6

  netmask=255.255.0.0

  ipaddr=172.16.16.220

  serverip=172.16.16.70

Output with minicom:

  $ tftp a1000000 little

Many timeout are occured. It seems hardware trouble...

I recommend recompile with debug flag of net.c and the driver's code
to get the more messages. also observe the packet with ethereal
or tcpdump command.

FWIW, I've noticed that the Lubbock SMC_inb macro in drivers/lan9196.h is
broken. Take a look at that Lubbock SMC_inb macro definition:

#define SMC_inb(p)	({ \
	unsigned int __p = (unsigned int)(SMC_BASE_ADDRESS + (p * 4)); \
	unsigned int __v = *(volatile unsigned short *)((__p) & ~1); \
	if (__p & 1) __v >>= 8; \
	else __v &= 0xff; \
	__v; })


I believe that definition should be rewritten as follows (ignoring issues
of coding style or personal preferences : ):

#define SMC_inb(p)	({ \
	unsigned int __p = (unsigned int)(SMC_BASE_ADDRESS + ((p) * 4)); \
	unsigned int __v = *(volatile unsigned short *)(__p & ~4); \
	if (__p & 4) __v >>= 8; \
	else __v &= 0xff; \
	__v; })


I don't have a Lubbock target so I can't vouch for the accuracy of my
assertion. But it clearly seems broken as currently written. Also have a
look at the Lubbock kernel lan91c96 support to review those macros there
and draw your own conclusions.

I have no idea if this will help with this problem. But it probably won't
hurt. : )

HTH!

You've probably checked this, but make sure the cable is good.  I've had 
a bunch of problems with crossover cables in particular.  For example, I 
worked on one board that had no problems with the crossover cable under 
Linux, but under U-Boot, TFTP just wouldn't work.  Using an Ethernet hub 
alleviated this.

I also have a Sony notebook computer that connects fine over a crossover 
cable to a 10Base-T card, but not to a 100Base-T card.

Consequently, I've pretty much given up using crossover cables, for the 
time being.

It sounds like some of you have duplex negotiation or mismatch 
problems.
