For example, if you were to build a battery powered BBB application that required low processing requirements, you could reduce the clock frequency to conserve power. You can find out information about the current state of the BBB by typing cpufreq-info:

Custom Kernel and Ångström Distribution Recipe (SPI/CAN bus Support)

I have already posted on how we can build a vanilla Angstrom distribution from source at this post: Building Angstrom for Beaglebone from Source. This post looks at how we can add SPI to the kernel and rebuild the Linux kernel and Angstrom distribution. The post isn’t specific to SPI, so it may be that you are looking to make […]
