I want to communicate stm32f407(bare metal) with the PC using ethernet (TCP/IP) and send as well as recieved data....How to do this can ay body guide me....I have experinced in writing linux systems  but not with this can anybody help me....

Several TCP/IP stacks can be found under ''Design Resources'' for the chip

The lwIP implementation is here

There are other IAP examples using Ethernet

HI clive

Thanks for the link .....but I have a doubt like my board is stm32discovery it doesn't have MAC and ethernet port within it . So without MAc how it will get the ip address ......how they are doing in the code the way they have mentioned it's bit complicated . What is this MII configuration mode and RMII configuration mode got to know  from the read me file. I am pretty sure some interface is required which is having MAC as well as ethernet port. for that which is the thing is available so that i can able to test. I mean which pin to connect they are using some DHCP server what it do exactly. Can you explain me some basics of this code which is acting as what .

Yeah, I'm not up for that level of tutorial stuff,

Want to add Ethernet to an STM32F4-DISCO, take a look at the

http://www.element14.com/community/community/knode/dev_platforms_kits/element14_dev_kits/stm32f4-discovery-expansion-boards

and it's supporting materials. There are other break-out board available, and boards like the WaveShare

and Olimex

LwIP is one of the possible TCP/IP stacks, there are others both free and pay. You get to hard code a MAC address, and chose if you want a fixed IP address or dynamic IP via DHCP.
