Dear lwip users:
I have a problem with
lwip+ucos-II+ADI-Blackfin532,for nearly a month,In my application,I
have several thread: main thread,tcpip_thread and
transmit_thread.Usually my application can send undefinite bytes data to
the client,but it will stop send data to the client,and
I find the following debug information through UART
output:
"In tcp_write(),len =0",and it will not call
tcp_enqueue,but actually I want to send data to client endlessly.And
why "tcp_sndbuf" sometimes will always be zero? Sometime I also
found that after a short period of time my application will come back
to life again and go on sending data to the client,but it still will
be dead at last.Please help me! Where can my application be deadlock??? Thanks a
lot.
note:I use lwip version:0.5.3
ucos-II version
2.75
