Hi. I try to operate lwip_tcpecho_sa examples without freertos. when dhcp is inactive, given ip,gw and mask is sended to uart port. TCP is default 7 in code (ı am not sure for that ? ). I ping this ip and this response is coming "target  host unreachable". I cant open tcp server with putty or hercules. 

when dhcp is active, ip is not set and sended default 0.0.0.0. 

Cables and component is true, ı checked it with easyweb examples.

I use mcuexpresso and ı have custom board with lpc1769.

How can ı solve this problem , Which settings should be made ?
