Eventually I’d like to set up two static IP (IPv4) on the Ethernet interface on the Zedboard: One IP address as a TCP server, and the other as a UDP client. -----lwIP TCP echo server ----- TCP packets sent to port 6001 will be echoed back WARNING: Not a Marvell or TI Ethernet PHY. Connection details and data transfer This project contains two echo servers (one using UDP and the other using TCP) implemented using lwIP RAW API and running on Xilinx Zynq platform. Dear all, I am currently using zc7045 chip, and trying to build a TCP connection on standalone system. You can't send more data with one tcp_write() call than there is available space in the send buffer. There are two instances of this server, each running on a different RPU in split mode. For Socket mode, you can use mutiple thread which is easy to program. Hello, I'm using lwip with FreeRTOS on a Xilinx zynq ultrascale\+ (R5 processor). - I build my hardware in Vivado 2014.
