5. Run Linux and RPU app
5. 1. Boot Linux using petalinux-boot
petalinux-boot --jtag --kernel
Note:
As per CR-973961, JTAG cannot run when cpuidle is on. So run script (zcu102.tcl) on xsdb to load petalinux images:
Load Images
xsdb% source zcu102.tcl
xsdb%Boot Linux on APU using SD Card by coping BOOT.BIN and image.ub on the SD Card.
Once above script execution is done,boot start U-boot prompt
...
on serial. Press Enter again and again to interrupt u-boot till ZynqMP prompt appear. Run below
ZynqMP > setenv bootargs ${bootargs} cpuidle.off=1
5.2. Run RPU app
If XSDB method is used to start linux, this step should be skipped.
...
(RPU application Application source) (rpu_deep_sleep.elf) when Linux is upup)
{rpu_deep_sleep.elf}
Perform following command on xsdb

Xilinx uses Yocto eSDK build system within our PetaLinux product which is the exclusive extent to which we test Yocto. Xilinx does provide Yocto recipes for all key components but we do not test these outside of the PetaLinux tools context. It is incumbent on our customers to address any issues between their own in-house Yocto build system and the Yocto recipes provided by Xilinx.

You can use FPGA Manager to load an FPGA bitstream onto the PL from Dom0. Follow the standard Linux instructions here: http://www.wiki.xilinx.com/FPGA+Manager+ZCU102 for details on loading the bitstream. This will only work from Dom0.
Additional Commercial Support and Professional Services
Xilinx recommends DornerWorks , one of our Premier partners to those who desire support beyond the topics and scope described above, for customization or optimization of one of the many elements of a full Xen-based solution including new DomU OS support, frontend drivers, and for optimization for performance, DMA, or boot time.

Overview
Xen is an opensourcea type-1 Hypervisor which isdefined, maintained and provided to the open source community by the Xen Project. Xilinx actively contributes code to the Xen Project to provide Zynq UltraScale+ MPSoC platform support as well as key enhancements which benefit Xilinx customer use-cases.
Xen allows users to run multiple instances of operating systemssystem(s) or baremetal codebare-metal applications to execute on a single host. For moreZ US+ MPSoC. Additional information on what the Xen hypervisor is have a lookcan be found at the projects overiew here: Xen Project Software Overview
Since page.
Xilinx provides within the 2017.1 release, Xilinx has support customers who deploy combinations of LinuxPetaLinux Tools and Xilinx bare-metal application guestsalso on Xen hypervisor. Information linked below will be very helpful as you work to configure, buildour GIT, core elements and deployexample designs that enable a software solution consistingbasic usage of Xen hypervisor + Linux Dom0 + Linux DomU + bare-metal guests.
Based onsystem configurations across the recurring need for our customers to optimize performanceprocessing cores of their bare-metal guests, our material currently focuses on configurations with "CPU Pinning", where physical CPU cores are dedicated to guest OS, and Z US+ MPSoC devices are dedicated for exclusive use by a guest.
