Samuel Jacob Posted January 3, 2013 Report Share Posted January 3, 2013 Is there a plan to create an Ethernet wing for Papilio?Or does anyone know any breakout board for http://www.micrel.com/_PDF/Ethernet/datasheets/KSZ9021GQ.pdf or similar?ThanksSamuel Link to comment Share on other sites More sharing options...
hamster Posted January 3, 2013 Report Share Posted January 3, 2013 If you were happy a 10/100 NIC, you could try using a PMOD (http://www.digilenti...rod=PMOD-NIC100) with a few short wire jumpers.I don't know of any gigabit equivalent. Link to comment Share on other sites More sharing options...
Felix Posted January 3, 2013 Report Share Posted January 3, 2013 iirc jack also mentioned a WiFi wing in progress or something Link to comment Share on other sites More sharing options...
Jack Gassett Posted January 3, 2013 Report Share Posted January 3, 2013 We've had an RMII Ethernet Wing designed for years now... The problem is that we have not found an Open Source Ethernet core that supports RMII yet... It should be possible to convert MII to RMII but there just never seems to be the time to do so. Alvie has a prototype board and in his work with Linux might get the time to bring the board up. But until we can get a core to support it the Wing is just sitting in my dropbox folder...I do also have a Wifi Wing, I started working on porting the libraries a couple weeks ago, but didn't get too far before I ran out of time. The WiFi Wing uses the same module, from microchip, that the Async Labs WiShield does. It should be just a matter of modifying the library to work with the AVR8 and ZPUino before I can get the ball rolling with making this Wing available. It will probably take a couple days with the logic analyzer to get it working.BPW5014-RMII-Ethernet_nl_1.0_.zipBPW5043-Wifi-Wing-V1.0.zip Link to comment Share on other sites More sharing options...
neslekkim Posted January 3, 2013 Report Share Posted January 3, 2013 what about the marvel chipsets?http://people.ece.cornell.edu/land/courses/ece5760/FinalProjects/f2011/mis47_ayg6/mis47_ayg6/index.htmlhttp://www.orangetreetech.com/mycms/files/products/datasheet/9.pdf Link to comment Share on other sites More sharing options...
neslekkim Posted February 12, 2014 Report Share Posted February 12, 2014 The ethernet wing that is in the shop now (But not buyable.. ) is that this wing? Link to comment Share on other sites More sharing options...
Samuel Jacob Posted February 12, 2014 Author Report Share Posted February 12, 2014 From pictures I read SPI ethernet wing. So does not looks like it will expose any ®MII pins. Link to comment Share on other sites More sharing options...
Jack Gassett Posted February 13, 2014 Report Share Posted February 13, 2014 Sorry guys, I thought that the page was hidden from view while we added all of the details about the board. It is a SPI Ethernet Wing, the details are posted and it is available for purchase now. Link to comment Share on other sites More sharing options...
neslekkim Posted February 13, 2014 Report Share Posted February 13, 2014 Yes, found it active yesterday and pulled the trigger, no use for it yet, but who know.. Link to comment Share on other sites More sharing options...
Jack Gassett Posted February 13, 2014 Report Share Posted February 13, 2014 Oh, I should mention, there is a 24 hour sale period going on right now. It's 50% off until midnight tonight, $9.99. Regular price is $19.99. Jack. Link to comment Share on other sites More sharing options...
mkarlsson Posted February 13, 2014 Report Share Posted February 13, 2014 Is there a schematic or ucf file available to guide me how to hook it up? Link to comment Share on other sites More sharing options...
Jack Gassett Posted February 13, 2014 Report Share Posted February 13, 2014 The pins are printed on the bottom silkscreen. I need to ask Logxen for the schematic. Jack. Link to comment Share on other sites More sharing options...
EtchedPixels Posted August 10, 2014 Report Share Posted August 10, 2014 Playing with this today getting it working in SocZ80 Useful things I have learned - 10MHz or less- SPI mode 0,0 only- 100nS is needed between deselect and reselect- 100nS is needed between the transaction end and deselection That was far too much fun because the chip responds to just about any SPI protocol timing violation of the above by almost working, everything the mac address writes which mysteriously fail a lot. I have added SPI mode 0 to the SocZ80 SPI master and figured out the delays. Unlike a little microcontroller that the libraries are written for on a 128MHz Z80 on FPGA you can violate them! I can now send and receive packets. On the bright side since we now do SPI 0,0 I can switch Will's SD card driver to use the correct SPI modes, which might explain why some of the cards I have didn't work.
