I'm trying to find out, where I can determine my RPi firmware version. I did sudo rpi-update recently and I know, that my current firmware version is c8da643e606a55971d22482ce829a6c109a6a7ad, because I save its number after firmware update. But for future, I want to be able to determine my firmware version somehow, and so far, I wasn't able to find any way by looking on the internet. There are many posts about finding kernel version, or GPU firmware version, but so far I haven't had a luck with finding way to show RPI firmware version.
Does anybody here know, how to determine that?
