Gumstix with LCD Pt. 1



Managed to make the LCD displaying the bootscreen and a login prompt. The framebuffer console is also working with an external usb keyboard. But no luck so far with TinyX, which segfaults upon startup and complains about the lack of several utilities  and  the  matchbox  window manager. After recompiling back and forth, the following post by Christ Dollar on the gumstix-users mailinglist helps to remain optimistic:

As you've noticed, the tinyx and microwin packages are broken in the
current buildroot (in fact, I don't think they've ever worked).  The
gumstix buildroot is a fork from the main uclibc buildroot, which is
made to compile for lots of arches other than ARM and gumstix. So some
of the packages are just migration artifacts from the original
buildroot.

There are alternatives for getting tinyx and matchbox running for
gumstix.  If you are comfortable with linux in general and have a decent
working knowledge of cross compiling then you should checkout the
Openembedded based gumstix build at gumstix.net  Just follow the quick
start instructions and build the 'gumstix-X11-image' which will give you
tinyx + matchbox + cairo + gtk etc.  It currently is just over 16MB in
size, so it will only fit on a verdex xl6, but work is being done to
make it lighter. I've used this procedure on a number of machines with
great success.

UC-232A USB 2 Serial adapter with Ubuntu

The Aten UC-232A is a serial interface adapter for RS232 to USB. Since there are no hints regarding the chip on neither the plug nor the package, googling unveiled that it is about a `PL-2303'. The appropriate kernel module can be configured under USB-to-Serial -> Generic Driver -> Prolific-2303 and leads to a module named pl2303.ko
