Re: [Gumstix-users] No response from my new Verdex...

[Dan T. <da...@lo...>]

Like I say, the cable I'm using works with my old gumstix but not with
the new one, so I'm pretty sure it's not that - unless there are
handshaking requirements on the verdex that aren't required on the
basix...?

Plugged the verdex into the old waysmall STUART/console-st board
(which again works with the basix) but got no joy there.

One other thing I noticed is that one of the 232 line driver chips is
missing from my consoleLCD-vx board.  The chip is shown as being
present in the following image, along with several components between
the USB and power connectors.

Probably a red herring.  If it was just a faulty console board then
surely my verdex would work with my old waysmall board...?
