ARINC653_ARMV7A_Z7000

Bare-metal Real-Time Operating System (RTOS) for Xilinx Zynq-7000 Cortex-A9 (ARMv7-A) multi-core SoCs (ZedBoard, PicoZed, MicroZed and similars) based on the ARINC 653 Part 1 specification

IDE installation:

• Run Xilinx Unified Installer v2018.3 (or a similar superior version)
• Select "Vivado HL WebPACK" installation
• Ensure "Vivado Design Suite", "Software Development Kit (SDK)" (with the ARM Cortex-A9 Compiler Tool Chain) and "SoCs/Zynq-7000" are marked

Compilation configuration:

• C/C++ Build / Settings / ARM v7 gcc compiler / Directories / Include Paths += "${workspace_loc:/${ProjName}/src/ARINC653_PORT/include}" (add to both "Debug" and "Release")
• C/C++ Build / Settings / ARM v7 gcc compiler / Directories / Include Paths += "${workspace_loc:/${ProjName}/src/ARINC653/include}" (add to both "Debug" and "Release")
• C/C++ Build / Settings / ARM v7 gcc compiler / Directories / Include Paths += "${workspace_loc:/${ProjName}/src/Test/include}" (add to both "Debug" and "Release")
• C/C++ Build / Settings / ARM v7 gcc linker / Linker Script = "../src/Application/ARMV7A_Z7000.ld" (change for both "Debug" and "Release")

MicroPhase Z7-Lite JTAG debugging configuration:

• J1 = 1-2 [JTAG]

Debugging on the target platform:

• Select "Run" -> "Debug Configurations..."
• Double-click "Xilinx C/C++ application (System Debugger)"
• Configure the debug configuration as follows:
  • Target Setup / Debug Type = Standalone Application Debug
  • Target Setup / Connection = Local
  • Target Setup / Reset entire system = TRUE
  • Target Setup / Program FPGA = TRUE
  • Target Setup / Run ps7_init = TRUE
  • Target Setup / Run ps7_post_config = TRUE
  • Application / Stop at 'main' = FALSE
  • Application / Processor "ps7_cortexa9_0":
    • Summary / Download = TRUE
    • Stop at program entry = TRUE
  • Application / Processor "ps7_cortexa9_1":
    • Summary / Download = FALSE
    • Stop at program entry = FALSE
• Click "Apply"
• Click "Debug"

Debugging on the second core (after the debug session is started):

• Select "Run" -> "Debug Configurations..."
• Select debug configuration to be used
• Configure the debug configuration as follows:
  • Symbol files / Debug context "/APU/ARM Cortex-A9 MPCore #1" ():
    • Click "Add..."
    • Select the project's ELF file
    • Click "OK"
  • Click "Close"

Programming the bitstream into the QSPI memory:

• Build the project
• Open the project in Vivado
• Open "Hardware Manager" -> "Open Target" -> "Auto Connect"
• In window "Hardware", right-click "xc7z010_1" and open "Add Configuration Memory Device..."
• Set "Manufacturer" to "Winbond"
• Set "Type" to "qspi"
• Set "Width" to "x4-single"
• Select the "w25q128fv-qspi-x4-single" part number
• Click "OK"
• Accept programming the device by clicking "OK"
• Set "Configuration file" to the "BOOT.bin" file built
• Set "Zynq FSBL" to the "fsbl/Debug/fsbl.elf" file found in the software project directory
• Click "OK"
