Description:
LG published the End-of-life notification for the 4.3” LCD Display that Gumstix, Inc. resells and supports with expansion boards. Current stocks of our displays will not be replenished; however, Gumstix is introducing a pin-compatible replacement from Samsung.
As of January 25th 2012, Gumstix is selling Samsung (LMS430HF26) 4.3" LCD touch screen as a replacement of the LG 4.3" LCD touch screen.
These two LCD touch screens are compatible and both work with the 4.3" LCD-ready expansion boards of the Overo series, such as Chestnut43 and Palo43.
Custom expansion boards should function without modification. There is a pin (35) that differs in the pinout description: a 3.3V connection required on the discontinued LG product ; however, on the replacement screen (Samsung LMS430HF26) the signal is ignored.
PCN 2011-1: POP memory change on each Overo COM: 256/256MB to 512/512MB

Gumstix is now shipping each OMAP35xx-based Overo COM built with Micron 512/512MB POP memory @ R3119 or higher.

Update on August 17, 2011: Gumstix is now shipping each OMAP35xx-based Overo COM built with Micron 512/512MB POP memory only: ie R3019 or higher.
Instructions: Gumstix Overo COMs with 512 MB RAM and 512 MB NAND flash require a recent version of MLO and u-boot otherwise they won't boot correctly. Bootable microSD cards with software older than Oct 2010 will not boot these upgraded COMs.
Gumstix recommends making a fresh bootable microSD card as per the instructions here:
The factory software here should correctly support R3019 Overos. This MLO and u-boot should support older kernels and root file systems if you have customized
this software.

Revision Number: R3018/R3118 and R3019/R3119 or higher
Description:
In preparation for the discontinuation of the Micron MT29C4G48MAKLCJI ·memory, in the spring of 2011 Gumstix started shipping some Overo COMs with 512 DDR / 512 NAND configuration from Hynix.
Gumstix has since switched to the Micron MT29C4G96MAZAPCJG, another 512 DDR / 512 NAND package-on-package memory. ·
An Overo COM ordered at www.gumstix.com may be fulfilled with either 256/256MB or 512/512MB memory - with the exception of the Overo Tide COM, which ships only with 512MB DDR. ·
Once this stock has been shipped, Gumstix plans to supply Overo COMs only with Micron 512/512MB POP memory.
- A board revision number of R3018 ·or R3118 (check on the white label on the top of an Overo COM) confirms that the Overo COM has been populated with the Hynix 512/512MB memory.
- A board revision number of R3019 ·or R3119 confirms that the Overo COM has been populated with the Micron 512/512MB memory.
- A ·number of 2899 or lower on the white label on the top of an Overo COM confirms that the Overo COM has been populated with the 256/256MB Micron memory.
For each volume, Gumstix plans to supply only Micron 512/512MB POP memory on each Overo COM.
