TWR-K60N512 kit and 10 Mbps Ethernet

[jes]

I had problems with getting the Tower start-up demo to communicate via Ethernet.  It was unresponsive to a ping at its reconfigured IP addresss (192.168.1.40).  I configured all the necessary macros to no avail.  Stepping through code everything appeared to be ok but still nothing.

I recalled that we had a problem with a previous product of ours in which either the IP stack or the Ethernet driver had a bug, I don't recall which, that prevented communications at 10 Mbps.  I was using an old 10 Mbps hub in order to capture network traffic (via Wireshark) which a more sophisticated switch would avoid sending toward the PC hosting the packet analyzer.  I switched out the 10 Mbps hub with a 100 Mbps switch and retried the ping.  The ping was successful.  So it appears the MQX RTCS code may not support 10 Mbps Ethernet or is there perhaps a jumper on the Tower Serial board that needs to be reconfigured or have I missed a macro defining 10 Mbps operation somewhere?

Has anyone else had problems with 10 Mbps operation of Tower or MQX RTCS code?

Did you get the TWR-K60N512 kit working with a 10MB connection?

Hi Joe,

I have a patch for the micrel PHY/K60/MQX which will renegotiate the link to 10 mbps.

Let me know if your still interested and ill send it you.

Hi Jonathan

Can you please share this patch with me as well?

WE seem to have the same issue

thanks in advance

Hi Igor,

sorry I missed you message before, do you still require the patch?

Just to be clear the patch is for MQX.

Drop me an email to jonathan@microwatt.co.uk and I will send it to you.

Try putting a jumper on pins 13-14 of J12 which selects 10Mbps Ethernet. That should make it work then.

See the data sheet for the PHY we have on the TWR-SER for more details: http://www.micrel.com/_PDF/Ethernet/datasheets/ksz8041nl.pdf

I put the jumper on but the device is not detecting the cable being connected.  Is there an additional step needed to get it working with 10MB?

Same problem here...any solution?
