Make sure to review the information behind each tab of that product page for more gumstic information and product specifications. The Gumstix Overo is built and sold by Gumstix, Inc. This is where you will provide information to the Linux kernel about your SPI device, so that it will allow you to communicate with it.


If you cat one of these files, you get, eg: Files that are needed such as bootloader and operating system to create a bootable disk imageare available below. So I had to manually change the defconfig file.

I’m okay with compiling a kernel and soft software, but I’ve never written a driver before.


This is a simple uEnv. Once you have tested the board, you may use Geppetto online to design and customize it for your own project. The company accepts no liability for any damage caused by any virus transmitted by this email. This page on the Gumstix Wiki explains in more detail how to.

SPI and Gumstix Overo w/Summit Board

JavaScript seems to be disabled in your browser. It’s the pendown signal on the touchscreen controller but it’s available if you aren’t using a expansion board with touchscreen support. Post by nw Post by will2km Post by Markus Svilans and its limitations. In this section, I commented out the existing definitions, and added.

Instructions and functions are explained in the file. For updates about your order, please contact us via chat below or email at sales gumstix. Thank you so much.

According to the PXA datasheetmost of yumstix pins are limited to 3mA, and a few can go upto 4 mA see page Things you might want to change are the bus speed and the mode. Set to ON by kernel during init not all configs, see board-overo.

Currently all the GPIO multiplexing for the Overo’s is being done by the bootloader U-Boot, so the conventional way to modify the pin muxing is to edit overo. That COM would then be turned over and connected into an expansion board, such as the Summit board shown on the left. Smith, the AeroCore from Gumstix offers everyone from enthusiasts to educators the opportunity to power their very own micro-aerial vehicle.


Spend less time writing and rewriting code and more time creating.

But anyways, it’s working. The alternative functions are described in the PXA Developer’s Manual link spj be found in the Featured links-box section 4.

There are some synchronous helper functions exposed by the interface to simplify the asynchronous behaviour of the Linux SPI system for protocol driver writers. Retrieved from ” https: Add sensors or remove unused components with the ease of a drag-and-drop interface. Thanks for your test-program though, i will definitely try that one tomorrow as well. To reconfigure pins from within a kernel module the following code can be used: If you are writing your own driver, it is probably more convenient to do it in the driver code itself.
