We're working on producing a new round of controllers -- the first since about a year ago -- and we have a new purchase of PicoZed's to build them with. Our previous builds used Rev C of the PicoZed and our latest builds use Rev E.
Unfortunately, somewhere along the manufacturing chain we missed some important changes between Rev C and E (http://zedboard.org/sites/default/files/documentations/Product%20Change%20Notification%20PCN17003.pdf). We had been using most of pins MIO10-MIO15 for a pair of I2C busses. With the removal of U1 and U2 as described in the PCN it seems those signals are no longer, by default, routed to the JX2 connector.
I just wanted to check a couple things with you:
1. Can you verify that flipping these jumpers will route the corresponding signals to JX2? We're not using the PicoZed's on-board eMMC. Would only flipping these jumpers result in any adverse behavior?
* JT14 (MIO13)
* JT12 (MIO12)
* JT13 (MIO15)
* JT11 (MIO14)
2. The PCN I linked (which is, admittedly, about 1.5 years old) states: "If for any reason the Rev-E board can’t be qualified Avnet can continue to build the rev-C boards but an MOQ may be required." Is that still valid -- can Rev C boards still be purchased (at some MOQ?)?
Thanks for any insight you can provide!
