someone actually using the two ethernet ports on sam440ep ?

Post by voxel »

tried to use the second motherboard port and just can't :(

"impossible to open port 1" is the only answer I get.

The device driver only supports one port.

For curiosity, is there a hardware limitation underlying this restriction?

Or is this a possible limitation of the driver itself?

As I said above, the device *driver* only supports one port.

Just to clarify, the device driver is only software restricted to using one port right?

If someone was to write a replacement (or a team member modifies the existing driver...) the second port doesn't have any hardware restrictions stopping it from being used concurrently right?

As far as I know, no one has ever tried to get both going. Certainly no support for two ports has ever been released for beta test.

Someone somewhere may have a project running, but I'm sure we would have heard of it.

So at this time the only restiction is the device driver only supports one port,

and is this specifically a software limitation?

If an alternate device driver was written, can both hardware ports be accessed concurrently or is it hardware limited to a single port usable?

No idea about the hardware specifics and is there hardware documentation in the repo with the device driver sources as reference for it?

Because I would certainly like to access a BeagleBone here by networking as well as USB without losing access to the rest of the LAN in the process.

so both network ports being usable concurrently are a "would like this" but not an essential right now.

Kinda hard trying to deal with some problems when even Sashimi isn't reliable enough to display data.

Ahh well.
I'll just keep trying with what I have.
