Introduction
The BSP is based on Yocto Project-based BSP for Intel® Atom® Processors (Formerly Known as Elkhart Lake) on IoT Platforms of MR3 version. In particular, Yocto 3.1 (dunfell) with 5.15.21 LTS kernel are used. Although this BSP is an x86_64 distribution, it's also possible to run a 32-bit application since IA32 emulation feature is enabled in kernel.
