Welcome to LQ!
I've had this problem when playing with an embended system with uclinux 2.4. I had a 3com switch which sometimes stopped working. I did look for the problem, I tried with an other switch (the exact same model, but a different part number, newer) and the problem disappeared. It was the only problematic switch out of 10. Maybe you're PHY is loosing link or a duplex problem?? Electrical problem??? I did not dig into the problem as changing the switch solved it. Still this problematic switch seemed to work well with PC. So I can just tell you that it happened to me... maybe borrow someone else's switch or hub. |
Thank you for answer.
well. it is something like methaphisycal problem. My switch works with PC great. Therefore packets from embedded system is worster than from PC. I can't understand it. I need to ensure that it is hardware problem. if it is not - that is my (programmer) problem. (it is very bad practice to remove own problems to someone else) I still asking for help. |
