Problems running K60FN1 tower with FNET code.

flacca — Wed, 18 Feb 2015 00:36:38 GMT

I'm looking for some suggestions on resolving very sluggish performance on the ethernet link. I have downloaded the example K60 shell code from the fnet site and it seems to be running fine on the tower. I have the K60 configured to run with a 120mhz core clock and the ethernet chip on the SER board is setup for RMII using the 50mhz clock. When I ping the tower from my PC I very rarely get 4 good replies without a time-out. Not sure how to resolve this....any debug suggetstions out there?

Hi Frank

Unreliability usually stems from the 50MHz clock source - check the jumpers carefully again and verify with the setups recommended in http://www.utasker.com/docs/KINETIS/uTaskerV1.4_Kinetis_demo.pdf (chapter 7).

If you have the TWR-K60F120M check with the binary at http://www.utasker.com/kinetis/TWR-K60F120M.html
