Hi All, I'm working on a small, portable, handheld device that is required to have gigabit ethernet available to a user for certain use-cases. In other words, this device will be used most of the time without the ethernet powered up. However, when ethernet is needed, I'll need gigabit. Since the device is very size-constrained, we'd like to include as little of the actual ethernet hardwar...

A bit OT for the group, but it is related to an embedded system ... I have an application that requires Ethernet to be extended through an existing RS485 serial link, such that I have Ethernet RS485 Ethernet. I'm aware that there are any number of copper wire Ethernet extenders that will work on bare copper, but unfortunately I have the serial link in the path so I can't get to t

There are many MCUs with embedded Ethernet (MAC). It seems most of the open-source examples are lwip-based. I have to design a board with one RS485 port and one Ethernet port. It could be seen as a serial-to-Ethernet converter, where the protocol on RS485 is proprietary. On Ethernet side I will contact a server (cloud) with a protocol that must be defined. At the moment, I don't need...

We are running application written in C# under .NET framework under Windows CE 6.0 on our hardware based on LPC3240 with PHY DP83848I. This application communicates with PC over Ethernet. Everything goes well when there is other activity on Ethernet. When we have quite Ethernet (no communication from other nodes) our application stops after couple of hours, e.g. every 2 hours. If during stop state...

I am thinking of developing an embedded device, and the device will transfer the data to the server via ethernet interface to internet. At the same time I would like to debug the device in remote. I think I can either use one ethernet, or two ethernet for the task. By using one ethernet, I can use one port address to exchange data between the device and the server, and another port address fo...
