Subject: [lwip-users] BSD socket communication with FreeRTOS
Hello.
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 well.
1) It can sends UDP data, I can check the packets. But it cannot receive any
data. It goes to line 366 in api_lib.c
(sys_arch_mbox_fetch(&conn->recvmbox, &buf, 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.
Thank you
