Marvell PCN Number: 0910071 (Marvell Document Number: MV-Q200026-00)
PCN Date: 10-AUG-09
Subject : PXA270 624MHz Supply
Description of Change by Marvell: Due to supply shortages, all PXA270 624MHz customers of Marvell (ie Gumstix) are requested to convert to the 88AP270M 624MHz device immediately...... This PCN only impacts the 624MHz version (of the PXA270 processor). All other speeds are not impacted.
As such, the only Gumstix product affected by this Marvell PCN 0910071 is the Gumstix XL6P computer-on-module.

PCN2009-5: R2277 changes the position of the 27 pin connector (J5) and the two antenna jacks on each Overo computer-on-module.
Notice Date: September 2009
Effective Date: September 2009
In reference to Gumstix Overo computer-on-modules:
Revision 2173 locates the 27-pin, J5 connector on the top of each Overo COM in a position next to the Bluetooth / Wifi module (R2173).
Revision 2277 and higher positions the 27-pin, J5 connector in a central position next to the OMAP processor. The pair of antenna jacks are also shifted slightly. These changes were made to improve RF performance.
These location changes are the only differences in layout R2277 as compared to R2173. There aren't any functional changes.
Gumstix is only shipping R2277 or higher of the Overo Fire COM and Overo Air COM.
As of October 27th 2009, Gumstix is shipping R2173 versions of both the Overo Earth COM and Overo Water COM modules until currenty inventory runs out. This stock depletion is projected to occur on or before the end of 2009, depending upon demand.
All future builds of any Overo Earth, Water, Fire or Air computer-on-modules will be completed using layout R2277 or higher.
A design engineer planning their product(s) based on the Gumstix Overo series should:

PCN2009-4: Change to Tobi expansion board to accomodate every Overo COM.
Notice Date: June 2009
Effective Date: June 2009
As of June 8th, 2009, Gumstx is only shipping Tobi boards of revision 2441 or higher to ensure that each Tobi expansion board will properly connect with each and every Overo COM.
The clearance between the Tobi expansion board and the components of the Overo COM has been designed to allow proper connection of the Tobi expansion board with any of the Overo COMs, including Overo Fire and Overo Air.
Gumstix recommends that the revision 2392 of the Tobi expansion board only be used with the Overo Earth COM and the Overo Water COM.
==================================================PCN2009-3: Change of pin 46 on Overo J4 connector
Notice Date: January 2009
Effective Date: January 2009
As of version 2106 of the Overo Earth, pin 46 on connector J4 has been changed to be 4030GP2_N_MMC3_CD.
==================================================
PCN2009-2: Removal of resistor R26 on Overo to allow EHCI (USB Host) to function.
Notice Date: January 2009
Effective Date: January 2009
Gumstix has determined that the removal of the resistor R26 from any Overo COM will allow the EHCI (Enhanced Host Controller Interface Specification for Universal Serial Bus) host controller to function. EHCI is also called USB Host.
Connection of the Overo COM to any Overo-capable expansion board, such as the Summit board, have a connector for a USB cable.
==================================================
PCN2009-1: Revision on the netpro expansion board to prevent physical interference with verdex pro
Notice Date: January 2009
Effective Date: January 2009
The micro-SD connector on the verdex pro board interfered with an IC on the netpro-vx in early versions of the netpro expansion board. This interference may cause shorts on pins due to metal to metal contact. As of January 2009, Gumstix has adjusted the netpro expansion board to prevent this interference.
