Problemy z wielokrotnym połączeniem TCP w module WIZNET W5100 przez SPI

Sat Feb 09, 2008 9:40 am   

witam,

czy ktos korzystal z tego cuda? Udalo mi sie uruchomic to to przez SPI,
otwieram socket (TCP), robie connect, send, disconnect i niestety nie moge
tej operacji powtorzyc. Zwisa mi na send, ale tak naprawde rzecz w tym, ze
bez software'owego resetu uklad na drugie polecenie connect nie posyla nic w
siec Ethernet. Podczas pierwszego polaczenia dziala ksiazkowo (SYN,ACK,FIN).
Testowalem juz rozne kombinacje rejestrow robiac ich zrzuty - jak dotad nic
nie moglo. Uklad utyka w grafie stanow na SYNSEND (cos go blokuje chyba
wewnetrznie, ze nic nie posyla) i stad dalsze proby koncza sie
niepowodzeniem.
Korzystam z modulu WIZ810MJ i sprawdzalem efekt juz na dwoch - powtarzalne.
Taiwanczycy nie odpisuja pomimo, ze poslalem im zrzuty rejestrow ukladu w
roznych stanach :/

pozdrawiam

P.S. Nie oczekuje odpowiedzi typu uzyj Ethernuta czy lwIP, bo nie w tym
rzecz. Jak nie odpale tego to tak postapie, bo doswiadczenie z nimi mam
(glownie lwIP).

Czy na pewno przed każdym połączeniem otwierasz gniazdko?

I try to implement TCP client (HTTP exactly) using W5100 chip. I do (using
functions from w5100.c/h and socket.c/h like for PIC24 demo):

INITIALIZATION
-----------------------
iinchip_init(); // SW reset
setSHAR(SHAR);
sysinit(0x55/*2K*/, 0x55/*2K*/);

// DHCP before?
setGAR(GAR);
setSUBR(SUBR);
setSIPR(IPR);

LOOP
----------
wait 0.5s
socket(s, Sn_MR_TCP, 0/*source port: temporary*/, 0/*flags: none*/)
connect(s, (uint8*)&iptl, 80)
send(s, dd, sizeof(dd)-1)
getSn_RX_RSR(s)
recv(s, &b, sizeof(b))
recv(s, &b, sizeof(b))
disconnect(s)

My problem: W5100 halts on send() in second loop. What is the problem?!

best regards
