Subject: [lwip-users] BSD socket
communication with FreeRTOS
I'm developing BSD socket UDP, TCP communication with FreeRTOS
now. I tested raw UDP, TCP without FreeRTOS in my system already and it works
well. But it doesn't work with RTOS. I reffered a few demo project offered by
FreeRTOS. sys_arch.c is also reffered it. I'm using lwIP 1.4.1. ping works
1) It can sends UDP data, I can check the packets. But it cannot receive
any data. It goes to line 366 in
conn->recv_timeout) == SYS_ARCH_TIMEOUT)
then the thread is closed..
2) TCP has another problem. I check some packets using Wireshark, there are
few packets between my system and PC. I can see the 3 way handshake.. But the
next packet has 'RST' it sent from my system..
Please let me know check point to solve these problems.
