Petalinux application to run on ZYNQ

[engr_joni_ee]

I am wondering how we can run different applications provided petalinux is already running on ZYNQ. Do we really need to compile and build the whole petalinux project to run a new application or we just load the new application through USB UART cable ?

The PetaLinux tool contains:
• Yocto Extensible SDK (eSDK)
• XSCT (Xilinx Software Command-Line Tool) and toolchains
• PetaLinux CLI tool

What benefits does the Yocto Project provide embedded developers and how is the Yocto Project superior to existing, similar tools?​

Unlike build systems based on shell scripts or makefiles, the Yocto Project automates how source is fetched from a variety of upstream sources or from local project repositories. Updating to a new version of a package is often as easy as renaming a recipe file.

From any source (SD, etc )
