Total build time for omap3-console-image was 2 hours and 20 minutes, on a iMac 27" quad-core i7 2. The virtual machine was configured to use 4 CPUs, 2. VMware Fusion cannot use more than 4 CPUs per VM, so I guess if someone were to run Linux native on a quad code, they would be able to utilize all 8 core and reduce the build times even further. This document describes how to setup a development environment for the Overo platform using a Fedora x86 bit VMware image.

If you need to create your own bootable microSD card, follow instructions to create a bootable microSD card step in the Getting Started Guide. If you just want to add some more software to your current image, check out the Add Software Package on the opkg package manager section. The following information explains how to set up a basic cross-compilation environment. These instructions are given for a Debian-based host system; however, they are similar for other Linux OS distributions.
First, we explain how to cross-compile just the Linux kernel and run it on your Gumstix device without using a full build system. First, we need to get the cross-compiler. From Debian, Ubuntu, or Mint, use the following command:. Next, we need to download the kernel source code, follow the steps under Compile from Source Code on this page.
Next you will need to get a default configuration defconfig for your architecture. We recommend you use the same defconfig Gumstix uses in its Yocto Project builds.
Currently you can find this at:. From these files, select the kernel version you are using, then your platform, and finally download the file defconfig. Overwrite anything already there. You can now run the configuration. Replace the -j4 option with however many threads you want GNU make to utilize. Usually using twice as many threads as CPU cores available is good practice.
Run depmod on the gumstix to make sure these new modules can be found. Grab any binary files that you don't build yourself from the downloads page section for Yocto Project. You may want to write a script that copies over the kernel automatically each time you build. If your kernel doesn't load, try using an earlier version.
If you can't login or the image freezes, try using a different rootfs. If you want to test the kernel without access to physical hardware, you can emulate the system using Qemu. You use it like this:. Note: this section of the page is not yet finished and requires additional content. Thanks for your patience and check back soon. A common case is building the Linux Kernel.
These blogs offer good information and can be a valuable resource:. Developing directly on Gumstix hardware i. Likewise, if codes you wish to run on the COM do not have a Bitbake recipe, and you would rather compile directly from the source, try compiling it natively on a COM. Please note that the exact instructions depend on the operating system running on your COM. For larger projects, you might consider cross-compilation or the OpenEmbedded Cross build system.
