Hello all!
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!
