But this hardware tweak did a trick! I have changed combinations to the configuration registers for many different startup configurations — my only conclusion is that the DMAEP version of the chip seems to work with nearly all combinations of MII register settings, it is difficult to stop it working!! I xatasheet looked at the datasheet to the point of desperation catasheet despair! Prague branch Temporarily out of stock.

Thanks you so much again, i spent 3 days trying to make this work. Datadheet help investigate the problem I have the following setup: It detects the cable type straight through or crossover and makes the appropriate changes. Pilsen branch Temporarily out of stock.
At this stage I have tried countless combinations of MII register settings and nothing dm9161aepp to get it to work. The only difference between these who setups is the PHY chips. I did some initial investigation. Read at least twice as it may latch. Who is online Users browsing this forum: Because of the clock DP Phy is not latching the configuration pins.

Please tell me some hints how to debug that. Few points to note: This is d9161aep I see. Also, step through your code to make sure the new PHYID is taken into account when calling getPhyId In this example below you can see how I take a different branch when the ‘EP’ chip ID is read back – In this case I setup the registers for use with my fibre tranceiver.
It is my guess the router took care of all that for me. Proceed to wholesale Login Registration Shopping cart 0. No registered users and 0 guests. What’s pin 45 SD connected to?

Next the same code is run on the board that has the DMEP version of the chip. Description of the problem. I guess my question is why is the DMEP being so fussy!! Pilsen branch Temporarily out of stock. Of course thanks, am aware of that, it was just easier to cut the track from pcb to see how will behave before i add additional cap.
