Hi im working on getting a Ecos conrolled ECU to communicate with a counterpart, using only the ethernet 302.ab MMI layer of Ecos with no phy present. So whats the plan? The plan, is to provide the whole os with a stump, creating the happy ilusion of a ever present connection. Has anyone done this previously? If so, can you hook me up with a link to a repo/sampleconfig, where this was done? Please keep in mind that im still reading into the ecos source...

Without PHY? Would you like to connect to a counterpart with using MII bus? Please remember about electrical constrains of the MII bus. > So whats the plan? > > The plan, is to provide the whole os with a stump, creating the happy > ilusion of a ever present connection.

First of all which controller/processor do you plan to use?

Has anyone done this > previously? Sure. It's done all the time in embedded devices that include an Ethernet switch. One port on the switch has a "reverse" MII interface that connects directly the the microcontroller's MII interface. >If so, can you hook me up with a link to a repo/sampleconfig, where >this was done? Not really, all the examples I know of are proprietary. Just take out whatever code you have that's trying to talk to a PHY, then configure the microcontroller's MAC to 100M Full-Duplex (or whatever you want for the link), and you're done. -- Grant Edwards grant.b.edwards Yow!
