![]() Obviously the output will vary depending on what hardware you are running the command on. You're done OP how to know the current MHz, not how to change it. For example : Raspberry Pi 3 Model B Plus Rev 1.3 You can type sudo raspi-config in LXTerminal, use the arrow keys to navigate to 'Overclock' and hit enter, hit enter again, and look at the MHz section under None. cat /proc/cpuinfo Processor : AArch64 Processor rev 3 (aarch64) processor : 0 processor : 1 processor : 2 processor : 3 processor : 4 processor : 5 processor : 6 processor : 7 Features : fp asimd evtstrm aes pmull sha1 sha2 crc32 CPU implementer : 0x41 CPU architecture: AArch64 CPU variant : 0x0 CPU part : 0xd03 CPU revision : 3 Hardware. With the latest version of Raspbian you can also retrieve the Pi model as a string by using : cat /proc/device-tree/model ![]() The reading the cpuinfo file is a useful technique if you want to find out this information within a Python script. In this example I have a Model B “Rev 1.0” with a hardware revision code of 0002. This is not the same as the Raspberry Pi Rev number sometimes used to describe updated PCBs. NOTE : The Revision number given in cpuinfo file is the hardware revision number. That is a plain old “Model B Revision 1.0”.įor models with multiple cores (Pi 2 and Pi 3) you will see a block of information per core with the Hardware/Revision/Serial numbers at the bottom. In this example I’ve got a PCB with a Revision code of 0002. This will give you a text output something like this : Processor : ARMv6-compatible processor rev 7 (v6l)įeatures : swp half thumb fastmult vfp edsp java tls The traditional method of finding the Pi Revision Number was reading the “cpuinfo” file by running the following command at the command prompt or via a terminal window : cat /proc/cpuinfo More information about the Pi’s GPIO header can be found on the simple guide to the GPIO header page. This can be run at the command prompt or via a terminal window :using : pinoutĪnd the output will look something like this :Īs well as the Pi Revision number this method also provides lots of other information including the position of GPIO numbers on the Pi’s GPIO Header and amount of RAM fitted. In the new versions of Raspbian the pinout command was added. OpenELEC es una distribución de Linux extremadamente ligera y de arranque muy rápido diseñada. In order to find out what hardware revision you have you can use two methods Method 1 – Pinout Utility OpenELEC proporciona un completo conjunto de aplicaciones de software para centro multimedia que incorpora una versión preconfigurada de XBMC y add ons de terceros con emuladores de consolas de videojuegos de estilo retro y plug-ins para DVR. It comprises a set of functions to identify various 32-bit and 64-bit x86 processors ranging from those released in 1980's like 386DX to the latest ones of the Intel Core and AMD Phenom microarchitectures. To edit, simply click directly on the text to start adding your own words. Methods for Finding Raspberry Pi Revision Number CPUinfo is a compact library written in the x86 assembly language completely.
