TFTP works. I applied the changes suggested by James Jiao. I've modified the udelay routine in /cpu/pxa/interrupts.c the way he explained and it works.

Why are you posting the very same message twice from two different mail addresses?
Please NEVER do this again!!!!
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)..
What happens then? Is there an error mesaage or what? Did you try to debug the problem?
Which can be the problem?? Newer versions work fine??
Ummm... did you try it out? If yes, what was the result? If not, why
not???
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!
