TWR-K60N512 cannot get ethernet to work.

[mvanlamz]

I have followed the instructions in the TWR-K60N512 Quick Start Demo Lab Guide, and all the demos work, except for the Web Server demo.

On TWR-K60N512 board, I changed J6 to pins 2-3.

On TWR-SER board, I changed J2 to pins 3-4, added a jumper to J3 pins 2-3, and added a jumper to J12 pins 9-10.

(For the last two, I borrowed jumpers from J5, as directed in the lab instructions.)

One other thing -- I don't have an SD card handy, so I skipped that demo.

With an ethernet cable plugged in, the ethernet jack does not light up. It is either defective, or somehow turned off.

What do you think? I am just starting on my first Freescale project, and I would appreciate any suggestions.

Do you have any LED turn on in TWR-SER? Have you run the usb examples as well?

Sometimes, TWR-SER is plugged incorrectly or backward. Make sure you could see a LED. Does the TWR-SER turn on a LED if the TWR-K60 is unplugged from the TWR system? This is just a proof of concept.

Hi Mike

We received two serial boards recently that didn't work due to bad soldering of the PHY on it. One could be corrected by re-soldering the pins. These boards were replaced and both new boards were then OK. This means that you may have received a bad board (?).

Try the test software for the tower from here: http://www.utasker.com/SW_Demos.html

also double check the settings from here (guide to running the test software from link) http://www.utasker.com/docs/KINETIS/uTaskerV1.4_Kinetis_demo.pdf 

If that runs it will presumably be due to a SW config error or similar. If it doesn't run and the boards are configured correctly I would try a new board.
