Is there a way to find the current firmware version number? Either the running version or the version currently installed in /boot?

uname -a shows only the kernel version, not the GPU "binary blob."

You can check the GPU's firmware version by entering the following on the command line:

sudo /opt/vc/bin/vcgencmd version

    The real question is why have they put it in such an obscure location? – Alex Chamberlain Aug 7 '12 at 8:12

    @AlexChamberlain, It is because of the architurcture of the linux operating system. The /opt folder contains the optional packages, That is why the vcgencmd package must be installed there – Suhaib May 17 '13 at 1:31
