The ping response is perfect:. Last edited by Jacon on Mon Apr 02, I have verified that dataaheet the same firmware running at Mbps worked only in MCB Can it replace the use of magnetics in such a case?

Ethernet PHYs have various ways of biasing themselves and the biasing of one brand of Phy will be different from another brand. Following lines mostly repeated from my previous post, for newcomers Hardware changes: You will vp83848 at least one transformer and terminating resistors on both ends. At my project hardware, the RJ connector was away from the DP Again, it depends on the Ethernet Phy’s you are interfacing to and that they get biased correctly.

Products Download Events Support Videos. We actually ran into lots of trouble making this chip work at all, but every problem we had was related to the driver for the MAC it was a nios2 softprocessor in an Altera FGPA I ran into two small problems, just as catasheet But naturally we’d like to have 10Base-T compatibility also if possible.

Just added some stuff from the lwip demo makefile, the. You do not have the required permissions to view the files attached to this post. I had successfully datasheeet this once in my carrier. I need to work at Mbps to increase my network performance. The end result will be frustration. According to the datasheet page 76, RMII uses two data bits.

Ping failure by the change of 10M to Mbps Mike Kleshov You should check the capabilities of your hardware. Maybe Diego, Again, it depends on the Ethernet Phy’s you are interfacing to and that they get biased correctly. I tested it using up to meters of Cat5 cable without problems. Items 1 and 2 are already on the mbed. We used a NatSemi development module that ep83848 the crystal and magnetics and all, we’ll copy that circuit when we flatten it onto our board.

You should check the capabilities of your hardware. Now “the registers and capacitors” are close to DP at my project hardware and the same firmware running at Mbps is working well on it.

So it’s not RMII mode. Thanks for datazheet support. Look up your Ethernet PHY part number and download the datasheet.

The Ethernet PHY is a separate chip on your board. Uh oh – I was about to build a board with dataaheet of these on it! And an errata to add. A cross-over connection should be no problem.

It may or may not support support link speed autonegotiation. Only cosmetic changes in lwip.
