I am using eCos V3.0 on my lpc2290 board. My board have 2MB nor FLASH(0x80000000), 1MB SRAM(0x81000000), DM9000EP(0x83000000, IRQ is EINT0). I modify the phycore229x's bsp for my board, now it works. But , i meet a problem, when it power on, I can ping the board, TTL is 1-2ms. A TCP server thread for echo received data, it worked well. After several minutes, I ping the board, it will no reply or the TTL over 1000ms. I use wireshark catch the packets, I find the PC send arp request,but the board no arp replay, or replay pack will delay above 20~30seconds, The TCP thread worked deviant also. But same time ,the timer, TTY worked well. can anyone help me? Thanks! Brg Jeff Liang 2010-03-24
