Hello everyone,
We are developing an app what communicate by TM4C1294NCPDT with LAN or WIFI,
however, it returns 'Timeout' from Ping Result when PING TM4C1294NCPDT via Router Ping Test,
we also tested on iOS / MacOSX through PING apps, but it's same result.
Besides, we have developed on TM4C1294 LaunchPad Evaluation Board perviously, iOS / MacOSX devices can PING it without any issues , even the router ping test works perfect.
We have no idea that why PING from Router Ping Test is failed and iOS / MacOSX devices cannot PING the designed board (TM4C1294NCPDT) and this board is based on Evaluation Board's design.
Could it be a layout problem or something?
We would very much appreciate a suggest to the article or a maybe an answer to this question.
Attached is the circuit diagram what we design.
