Subject: | [lwip-users] BSD socket communication with FreeRTOS |
Date: | Tue, 4 Nov 2014 15:58:10 +0900 |
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
