How to check whether a Raspberry Pi is 32 bit or 64 bit ?

The latest version of Raspberry Pi comes with 64 bit CPU, but prior to that it was with 32 bit CPU. Some softwares and applications are dependent on CPU and OS architecture.

There are various options to check the architecture.

Method 1:

type the following command and check the response

uname -m

You will get a response something like armv7l or armv8.

ARMv7 and below are 32-bit. AMRv8 introduces the 64-bit instruction set.

Method 2:

Install lshw using the command

apt-get install lshw

Then type the command lshw.  You will be able to find the architecture from the response of the command.


Raspberry Pi 3 released.

Raspberry Pi 3 got released this week. Still remembering the moment before 3 years, my colleague introduced me about this magic device. Then I googled about this device and read the details. I am using this device from the past one year . I have used Raspberry Pi B+, Pi2 and now waiting for the delivery of Pi3 from element14. It is one of the superb devices that I have ever used. I can use my electronics knowledge and computer science knowledge using this. Now the Pi3 came with builtin wifi and bluetooth module so that it can be connected to a wifi or a bluetooth device without any external peripheral. Physical appearance is same as that of Pi2, but this version is more powerful. Now we can say Good Bye..!!! to wifi adapter modules. This will be a very big hit in the IoT market. Expecting more wonders from element14. 🙂
