2. Review GBT-SCA Development Card Zedboard
I’m sure you guys remember what I’ve been up to.
This setup has mostly just been for practice -- the important part is learning how to work with the Zynq SoC.

3. Zynq Workflow PC UART JTAG Ethernet Include packages (i.e. python)
Create Petalinux project
Add custom applications
Build PetaLinux project
Boot on SD card
Running system
Create hardware design in Vivado
Program FPGA from SDK
Install and debug through SDK
SCP scripts
Run bare metal application
JTAG
Write application in SDK
Ethernet

4. Building PetaLinux Distribution
Include packages (i.e. python)
Create hardware design in Vivado
Create Petalinux project
Add custom applications
Build PetaLinux project
Boot on SD card
Building PetaLinux Distribution
Kernel configuration
drivers, filesystems, etc
rootfs configuration
Python (with standard library: sockets, ctypes, etc)
Custom applications and modules
Cross-compilation

5. SD Card Boot Mode Load BOOT.BIN and image.ub files onto SD card

6. But Why?
Implementing an integrated software framework on Zynq-based emulators for HGCal DAQ and test orchestration
Create documentation so that other people can follow through the same process
So my project started off with my mentor giving me some circuit board and telling me to see what I can do with them. There were a lot of different possible directions that my project could go in, but we weren’t entirely sure what it would end up looking like. Over the past few weeks, we’ve formed a much more solid plan for me going forward…
Look at diagram -- everything is Zynq! wowza!

7. Working toward a framework
Idea: Have some python-based system that can use ctypes to call on-Zynq applications
Yocto: TCP/ZMQ, python-pip
Pyrame? GCC/GDB? On-Zynq debugging? Who knows! PL PS
Firmware
Library/Driver
Python + network
FW API ctypes TCP, ZMQ
