Based on the interest and number of embedded modules currently available, it appears that the OMAP3 CPU from TI will be very popular in the general purpose embedded Linux market. One of the OMAP3 modules available is the Overo from Gumstix. As the company name suggests, this module looks about like a stick of gum, […]
One of the most common power management modes for ARM processors is the suspend mode. In this mode, peripherals are shut down when possible, the SDRAM is put into self-refresh, and the CPU is placed in a low power mode. A useful bit of information is to know how soon the system can respond to […]
The Gumstix Overo Pinout Spreadsheet has been updated with the Palo board connector pinouts, and a few mistakes have been fixed.
As we look at new projects, both the Intel Atom and the TI OMAP3 processors generate considerable interest. As we have already shown, the OMAP3 does offer a considerable performance improvement over earlier generations of ARM CPUs. The following video I found on YouTube shows a similar comparison of a OMAP3 and Atom systems rendering […]
Several of my customers have built applications using the GTK+ tookit. While GTK+ works fairly well for what we have done, I have been wondering how the performance compares on the new Omap3 processors from TI. As we are evaluating the OMAP3 for several projects, I did a simple comparison with an existing application. Below […]
One of the first things I do when designing a system based on a processor module is create a spreadsheet listing all the connector I/O. This is the easiest way I’ve found to make sure nothing gets missed. My first pass at a I/O spreadsheet for the Gumstix Overo is available at: http://redmine.bec-systems.com/bec/documents/1
