FRWY-LS1046 J67 Connector Pinout

[matthej]

On the FRWY-LS1046 eval board getting started guide, figure 4 on page 5 shows a picture of this evaluation board. If you zoom closely it shows the pinout of J67 connector as follows:

2   1

4   3

 etc, but the actually board shows the connections as

1  2

3 4

etc. Which is the correct pinout of J67?

Thanks,

Matty

Here is the photo of the actual board. You can clearly see that the pinout is reversed. Look at pins 19 and20 on J67

The photo you provided corresponds to the Rev.B of the FRWY-LS1046A board which design data (including PCB layout and schematics) is available by the link:

In the Layerscape FRWY-LS1046A Board Getting Started Guide, Rev. 1 there is photo of the Rev.A (prototype) of the FRWY-LS1046A.

Can someone please help? I received an email back from NXP asking for clarification which I sent back in an email. But anyway here is the issue:

The acutal board which I have shows the pinout for the J67 connector as

1 2

3 4

etc.

If I look at the photo on the FRWY getting started guide the photo on there shows

2  1

4  3

etc.

Please verify which is correct?

Thanks!
