TRK-USB-MPC5643L Rev B?

I just bought a second (I'm a big spender) TRK-USB-MPC5643L, and when it arrived the bag was marked "REV B".

Comparing with my Rev A, the only obvious difference, besides the silkscreen, is the addition of J11, which (no surprise here) doesn't appear in my Rev A schematic.

Does anyone know what J11 does? It comes not-connected (no jumper installed, e.g.); should I just leave it that way?

More generally: Are the Rev B schematics available somewhere?

Hi, I have just obtained Rev B schematic (see attachment). J11 only enables pull-up for CAN0_RXD pin.

I haven't found the schematic anywhere. I have send a question to the factory engineer waiting for his response. I will let you know as soon as possible.

Thank you. In the meantime, I did plug it in, and it worked fine without J11 populated.

I'm still interested in finding out what J11 does (along with any other Rev B "goodies").

Somewhere on the board should  be a number very similar "700-27701". Could you please tell it to us?

On the bottom of the board there is a (silkscreen) box with two lines: "SCH-27701 / 700-27701" . This marking is the same for both boards.

On the top of the board there are 3 lines: "SPF-27701 / TRK-USB-MPC5643L / "<copyright>, where <copyright> is "(c)2012 FREESCALE" for the old board and "(c)2016 NXP" for the new one.
