About Build Machine

To create an image of bc10-router, a build machine is needed. The detail specifications of the build machine, such as its software and hardware, are shown below.

  • CPU: Coi7 2.93GHz
  • Memory: 8GB
  • OS: Ubuntu 10.04 (64bit)
    • kernel: 2.6.32-43-generic

Build System

To create the image of bc10-router, these two build systems are used.

arago-project

This is a part of OpenEmbedded Linux Project, which is maintained by TI. The information of how to create the build system, which uses arago-project, is listed at bc10-router/arago-project.

buildroot

This project is managed by buildroot, which provides a set of Makefiles and patches for generating an embedded Linux system. This uses the buildroot, which is originally and specifically created for beagleboard-xm. For farther technical information of buildroot, please visit bc10-router/buildroot.

To measure the network performance

The network performance of bc10-router is measured, and the results of the measurement is published. The details and results of the network performance measurement are listed at the page of bc10-router/network performance measurement.

To Update System

To improve the network performance of bc10-router, the image's linux kernel is updated. The image is created by arago-project. The steps of how to update are published at bc10-router/kernel update.

As linux kernel is updated, u-boot, which is the second boot loader for OMAP3530 is also updated. the process of how u-boot is updated is shown at bc10-router/u-boot update.

tftpboot

As kernel is frequently updated, such as in a development, u-boot's tftpboot is highly useful. For the farther information of how to execute tftpboot, please visit bc10-router/tftpboot.

Power Management

This article reports the operation verification for the power management of OMAP3540, which is used for bc10.

cpufreq

The results of the examination of cpufreq, the dynamic operating frequency change function, are reported at bc10-router/cpufreq.

Suspend / Resume

This section examines the details of Suspend/Resume of OMAP3530. In Suspend is state, the current operating information is stored into the memory, then CPU goes to sleep status. Resume is the revere of Suspend. CPU brings back the saved information from memory and goes to active. For the details, please look at bc10-router/Suspend Resume.
