Update the Firmware and Kernel
The Debian image already comes with firmware for the Pi, but the developers of the Linux kernel and the Pi’s firmware release updates frequently. New releases usually contain bug fixes and improvements, so it’s beneficial to update both the kernel and the firmware from time to time. To check which versions of the kernel and firmware are installed on your Pi, run the following commands:
| | pi@raspberrypi ~ $ uname -a |
| | Linux raspberrypi 3.10.25+ #622 PREEMPT Fri Jan 3 18:41:00 GMT 2014 armv6l GNU/Linux |
| | pi@raspberrypi ~ $ /opt/vc/bin/vcgencmd version |
