lwIP needs you to provide some time base. That depends on you using NO_SYS=1 (usually bare metal) or NO_SYS=0 (OS underneath). The fact that you are getting the linker to signal a missing file is an indication that you are missing part of what lwIP expects, according to the way you configured it. I ported to bare metal (NO_SYS=1) so I can't help you with FreeRTOS, you can check out the wiki or the already running FreeRTOS ports around. The wiki is at wikia: http://lwip.wikia.com/
PS: Search the list, I think this has been answered before. _______________________________________________ lwip-users mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/lwip-users
