serverip: IP address of your PC or server.Now, let’s configure networking in U-Boot: If that’s not the case, you can reflash U-Boot on your board using our instructions. This part may just work out of the box if the U-Boot version on your board is recent and was built using the default configuration for your board. These instructions should also support the Pocket Beagle board, which is similar, though much simpler. All you need is the USB device cable that you’re using for power supply too. Note that the below instructions also work on the original Beagle Bone Black, bringing the convenience of not having to use an RJ45 cable. Something easier to use is networking over USB device (also called USB gadget as our operating system is running on the USB device side), which is supported by both Linux and U-Boot. The Beagle Bone Black Wireless board has WiFi support, but booting on NFS directly from the kernel (instead of using an initramfs) is another kind of challenge. However, things get more complicated with boards that have no such port, such as the Beagle Bone Black Wireless or the Pocket Beagle. There’s no need to transfer them in some way.ĭoing this is quite straightforward on boards that have an Ethernet port, and well documented throughout the Internet (see our instructions). Whyīooting a board on a root filesystem that is a directory on your workstation (development PC) or on a server, shared through the network, is very convenient for development purposes.įor example, you can update kernel modules or programs by recompiling them on your PC, and the target board will immediately “see” the updates. I’m writing this here because it doesn’t seem to be documented anywhere else (except in our Linux kernel and driver development course, for which I had to support this feature). Here are details about booting the Beagle Bone Black Wireless board through NFS. BeagleBoneBlack Wireless board booting through tftp and NFS
