The Kernel - BeagleBone - page 474

Solution
Use the following command to determine which kernel you are running:
bone# uname -a
Linux beaglebone 3.8.13-bone67 #1 SMP Wed Sep 24 21:30:03 UTC 2014
armv7l
GNU/Linux
The 3.8.13-bone67 string is the kernel version.
To update to the current kernel, ensure that your Bone is on the Internet ( Recipe 5.13 or Re-
cipe 5.11 ) and then run the following commands:
bone# apt-cache pkgnames | grep linux-image | sort | less
...
linux-image-3.15.8-armv7-x5
linux-image-3.15.8-bone5
linux-image-3.15.8-bone6
...
linux-image-3.16.0-rc7-bone1
...
linux-image-3.8.13-bone60
linux-image-3.8.13-bone61
linux-image-3.8.13-bone62
bone# apt-get install linux-image-3.14.23-ti-r35
bone# reboot
bone# uname -a
Linux beaglebone 3.14.23-ti-r35 #1 SMP PREEMPT Wed Nov 19 21:11:08
UTC 2014 armv7l
GNU/Linux
The first command lists the versions of the kernel that are available. The second command
installs one. After you have rebooted, the new kernel will be running.
If the current kernel is doing its job adequately, you probably don't need to update, but
sometimes a new software package requires a more up-to-date kernel. Fortunately, precom-
piled kernels are available and ready to download.
