JTAG

Relocate the 120-pin connector on future versions of verdex motherboards and daughtercards
Verdex motherboards produced for the product launch have the 120pin connector relocated when compared to pre-launch boards. The 120-pin connector has been moved away from its nearest edge by 0.75mm.

This improves escape-routing on daughtercards from the connector towards the edge of a 20mm board significantly.

Connect the netCF-120 Board First
REQUIREMENT:

Connect the netCF-120 expansion to the GS270 motherboard first. Then, connect a 60-pin connector board such as the breakout-gs or console-st expansion board after connecting the netCF-120.

REASON:

The memory chips on the GS270 motherboard are fragile and can snap with excessive force. There is a warning printed right on the motherboard that shows where force must be applied when attaching the GS270 motherboard to the netCF via the 120-pin connector.

Attachment of the netCF expansion board must be done FIRST. If that is NOT done, there is a risk of applying excessive force directly to the chips from the STUART or breakoutGS boards.

Mounting holes
The verdex motherboard has 4 mounting holes: 2 holes are located near the 60-pin connector and these match the basix and connex mounting holes near the connector. There are two additional mounting holes in the verdex motherboard: 1 in each of the opposite end's corners for a total of four (4) mounting holes on the verdex motherboard.

The NetCF-120 board needs four mounting holes facing those of the verdex motherboard.

SVN for the verdex motherboard
Go to the HEAD of the 270 branch.

The 270 code will be merged onto the main trunk before launch, but for now, it's in a separate branch. You can check out this branch by doing:

svn co http://svn.gumstix.com/gumstix-buildroot/branches/users/craig/270 cd 270 make defconfig make ...

The "270" directory then has your complete buildroot in it.
