Raspberry Pi setup with L515
Unable to download SDK 2.0, i need to download it to access the pyrealsense2. I am using Raspberry Pi OS.

Hi Vipulatluri98 If you have the option to use the Ubuntu OS instead of Raspberry Pi OS then I would recommend doing so, as installing librealsense for Ubuntu on Raspberry Pi can be difficult and doing it for Raspberry Pi OS (formerly Raspbian) even more difficult.
If you need to use Raspberry Pi OS then the Acrobotic guide for installing librealsense and pyrealsense2 on a Pi 4 with Raspbian may be the best reference to use.

It is over three years old though, so may need updating in places. For example, in the part of the guide where it suggests installing protobuf 3.10, a newer protobuf version (at least 3.12) can make the process of bulding librealsense smoother.
If you have problems with building with the Acrobotic guide then one Reasense user at the link below found that using gcc7 and g++7 helped.

If you would like to install on Ubuntu then I would recommend the libuvc backend installation method at the link below, as libuvc works well with Pi boards.
https://github.com/IntelRealSense/librealsense/blob/master/doc/libuvc_installation.md
With the libuvc backend installation method, you run a pre-made installation script called 'libuvc_installation.sh' to initiate the install.

Having an L515 camera is a complication though, as the libuvc procedure will attempt to install the latest version of the librealsense SDK, but support for L515 was removed in version 2.54.1 as it is a retired camera model.
In a recent case at the link below, I suggested a method for modifying the libuvc procedure to install the earlier 2.53.1 version of librealsense which still had L515 support.
