FRDM-K64F, NRF-CE is no longer connected to PTC12


I have-3 FRDM K64F cards, one is a "REV D1", the other two are "REV E" (sch, see the bottom side). On the card REV D1, NRF-CE is connected to the port PTC12 (as reported in the documentation), but on the other two cards (REV E) NRF-CE is connected to PTB20 port.

The reference card of the two boards revision "E" do not reflect the change ...

I do not know yet where is now connected PTC12 (but I will look)


When I write NRF-CE, I mean "pin 3 of connector J6"

jsut look at the schematic, all revisions should be available for download on freescale webpage. Not certain what "reference card" is..

Are you sure? Can you show me the link? In the "download" section, I only see (now) the schematic version D1 -03/21/2014-. (http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=FRDM-K64F&fpsp=1&tab=Design_Tools_Tab#)

... But you're partially right. In "Printed Circuit Board bill of materials and design files: Available files and documentation for printed circuit board" in the zip FRDM K64F-file, there is a "SPF-28163_E1.pdf" file which is the latest schematic version (E1). All Other occurrences of the schematic for now refer to the version D1.
