i just got a brand new AT91SAM7XC-EK and tried the lwIP demo. it compiled fine with arm-elf-gcc and i flashed it via jtag (with openocd). The web server demo works fine at first, but after a couple minutes at most, it’s no longer accessible (trying auto-refreshing web access only, with no other IP traffic to the board). when the web access blocks, the leds still keep blinking the same, so i guess freertos didn’t freeze, but the ip stack seems dead (doesn’t even take a ping any more, which had worked before trying the web page). the link/act led still blinks showing ethernet packets, but that’s all. It happens systematically, though not always at the same time / page hits count. with auto-refresh web access alone, i once got over 400 int the “page hits” count (which always gets incremented by 3 between refreshes), usually it stops before. when i try to access from another machine simultaneously or with a simultaneous ping, it can go down to 25 “page hits” before the ip stack freezes (btw since the reset button doesn’t work in this demo, i have to take the usb power cable out between tries.) But as i said: the 4 leds near the joystick go on blinking normally.
any clue what might be the source of my problem?
