Issue: Older versions of u-boot than -R1604 have a known problem with duplicate serial numbers and MAC addresses. This is a result of an error in the a hash function that takes Intel's factory-assigned serial number from the on-board flash to generate a MAC address.  

Resolution: Gumstix Engineering believes that this hash function error was resolved by a patch which is included in u-boot version 1604.

As of October 2008, all verdex and connex motherboards are shipped with u-boot 1604 and with a Gumstix factory-issued serial number that is included in the OTP area of the on-board flash. Basix motherboards do not all include this feature. 

Older motherboards, shipped with u-boot versions before 1604,  still require a hash of a known-unique serial number that is embedded in the on-board Flash chip.

Any motherboard with a u-boot version older than 1604 should have this u-boot updated to u-boot 1604 to ensure correct hashing of the Flash serial number.

The change to a Gumstix factory-issued serial number will generate the MAC address now using the Gumstix OUI (OUI - Organizationally Unique Identifier, also referred to as 'company id'). Thus becoming a universally administered MAC address instead of a locally administered MAC address.

 

 

As of September 2008, Gumstix has introduced the verdex PRO product line to replace the verdex product line in OEM projects and is phasing out the verdex product line, as per the EOL information posted here.

The PXA270-based "verdex PRO" product line addresses a number of issues including the recent discontinuance by Molex of their 120-pin connector that Gumstix uses in the verdex product line.

Gumstix recommends that all customers designing an OEM product use the verdex PRO product line rather than the verdex product line.

 Important: Take note of the "Introduction and key items" section section of the verdex PRO information to understand changes and relative issues.

Gumstix is shipping netmicroSD and netwifimicroSD boards of PCB version "PCB10039-R1700", as written next to the microSD connector.

Erroneous part: Some boards produced in late 2007 and shipped as recently as early January 2008 have proven to be faulty. These faulty boards can be identified by the chip labeled "U11" which has, as its second line, the identifying characters "WBH4245".

Issue: Any netmicroSD and netwifimicroSD boards with a U11 chip of this "WBH4245" identification will prevent attached verdex motherboard from booting.

Resolution: Customers that have a board(s) with the U11 chip labelled "WBH4245" should contact This e-mail address is being protected from spam bots, you need JavaScript enabled to view it for an RMA.

Note: PCB10039-R1700 Boards with the chip labelled "WB4245" (no letter H in the label) are NOT considered to be faulty under this notice. Customers having a problem with a PCB10039-R1700 expansion board with the chip labelled "WB4245" (no letter H in the label) should contact This e-mail address is being protected from spam bots, you need JavaScript enabled to view it to request an RMA.

Issue: CRC errors present when booting some recent verdex XL6P motherboards.

Features: At boot, the system emits well more than 10 of the following errors:

JFFS2 notice: (213) jffs2_get_inode_nodes: Node header CRC failed at 0x9199dc. {0080,0080,00800080,00800080}
