Hi, all lwip fans:
Last week I had ported uIP to Hitachi H8 series MCU (h8/3664F and H8/3069F),
and I have put it on my homepage (http://www.i-da.co.jp/~tyou/embd/embedded.htm
)
And these days I am porting Lwip to Hitachi H8/3069F with Hitachi C
complier. Several
days ago I sended a mail about that mem_sanity will never goes out. now I have
found
out where is wrong with my codes instead of abort(); I made a mistaken that I
forgoten the {}.
if (c< 0) {
xxx
while(1);
}
:(((((((
Now the Lwip is working ,with SLIP baud rate 38400, it has handled 1000 times
of ping from the slip client, windows2000.
And these two days I am debugging with the httpd application. I got
problems :
the Lwip can establish TCP link, but http client of windows2000 can not receive
the data needed.
from the lwip printf logs, seems send out segment failed and finally TCP timer
overflows.
I debug it only with my DIYed boot loader, so I can not find too much clues
of the codes.
the http client logs are as follows :
//////////////////////////////////////////////////////////

As the lwip side , the logs txt file is attached.
If anyone has experience of this problem , please give me a hand.
thanks. btw , the enviro:
