Posted on June 17, 2015 at 18:31I am trying the LwIP TCP/IP stack demonstration for STM32F2x7 microcontrollers based on LwIP TCP/IP stack and FreeRTOS on a STM3221G-EVAL board,(
http://www.st.com/web/en/catalog/tools/FM147/CL1794/SC961/SS1743/LN1734/PF257896
), particularly the
UDP and TCP echo server application
described at the application note AN3384, and running the firmware under folder
LwIP_UDPTCP_Echo_Server_Netconn_RTOS since I am using FreeRTOS.
I am running the echotool on a couples of PCs, but the firmware respond to only 1 PC at a time. When responding to echotool running on 1 PC, I am getting timeout responses on the other PC.
Also getting the error of “Only one usage of each socket address (protocol/network address/port) is normally permitted�?, any ideas?
Thanks,
