Hi There,

I have to implement something similar to a cluster of microcontrolers. We run on Fedora and are going to connect FPGA Xilinx Spartan kits and OMAP l138 DSP/ARM.

You can see what I mean on page 2, figure 1 here:

From the same link, on page 5 is listed the IP from eacy board in that example, but not how to get the IPs.

In fact the development boards are already wired and connected to the intranet through a switch plugged to the LAN.

My question is, how to get the list of devices in my intranet, and have the info about some IP that belongs to a specific DSK, instead of belonging to a printer, or desktop, laptop?

Thanks in advance.

You could squeeze the arp table out of the switch and use the mac addresses to get further information. The first 3 bytes in a mac address are manufacturer info, that might help seperating your microcontrollers from any other network device like printers and desktops.
