One issue that is related is the case where you now wish to use a proxy with your device. This is common within universities and other organisations and the limits on what […]

Network routers typically run a DHCP server that allocates a pool of addresses to devices attached to the network. While DHCP works well for most devices on a local network, it can cause difficulties if you […]

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:

You can see […]

Automatically Setting the Beaglebone Black Time Using NTP

Setting the Time on a Once-off Basis
On my current distribution the Beaglebone Black does not come with a working NTP installation in order to set the time. Because the board doesn’t have a battery backup, this means that we need a way to set the time when the board is running. If you wish to set the time you could […]

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 […]
