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??
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.
