Hi,

I've got an ARM chip that will interface with a RMII chip for 10/100 Ethernet connectivity. I know that RMII well defines the electrical signal interface but what is the story on software level? Are all RMII ICs compatible or do they need some kind of driver adaption on my ARM?

Thanks
/Bjorn

Popular phy chips seem to be dp83848 and the smc lan7xxx series. Yes, there are differences. See the discussions on mbed and lpcxpresso sites.
