Zynq boot process, Sep 10, 2025 · BOOT. Stage-2 : Typically this is the user design that will run on the processing Booting Zynq Now that we have looked at the traditional Linux boot process, we shall now focus on the changes that are introduced when booting Linux on a Zynq device. The Cortex-R5F -0 processor also supports lock step mode. Boot and Configuration This chapter shows how to integrate the software and hardware components generated in the previous steps to create a Zynq® UltraScale+™ boot image. Without operating system Power-on: Boot ROM -> First stage boot loader (FSBL) -> User application: System running With operating system Power-on: Boot ROM -> First stage boot loader (FSBL) -> Second stage boot loader (SSBL) -> Linux May 30, 2024 · This section describes the boot and configuration sequence for Zynq 7000 SoC devices. Stage-1 : Typically this is the FSBL (First Stage Boot Loader). BIN is the core boot image file for the ZYNQ 7000 series SoC. Stages of the Zynq Linux boot process Stage-0 : On power-on reset, system reset or software reset, a hard-coded boot ROM is execute on the primary processor. Post-configuration stage After FSBL execution starts, the Zynq UltraScale+ MPSoC enters the post configuration stage. It can, however, be any user controlled code. BIN file. Boot process – Configuration Stage – CSU Details CSU – Configuration Security Unit Determines the boot mode / boot device (by bootstrapping Zynq external pins) BootROM can boot from following devices: FLASH - Quad-SPI, SD, eMMC, NAND JTAG USB through Device Firmware Upgrade (DFU) protocol The boot image BOOT. The Linux kernel initializes CPU1 and provides SMP support. This chapter also covers how to create a boot image and how to program a flash device. (A boot image is a packaged file containing multiple programs or data required for system startup, typically a binary file used to guide the system through the entire process from power-on to operating system launch. Instructions on how to build the Xilinx Shell Archive (XSA) handover file can be found here: Dec 3, 2025 · There are two boot flows in the Zynq UltraScale+ MPSoC architecture: secure and non-secure. Through the boot header, you can execute FSBL on the Cortex®-R5F -0 / R5-1 processor or the Cortex®-A53 processor. The following sections describe some of the example boot sequences in which you bring up various processors and execute the required boot tasks. BIN is built using the bootgen tool which requires several input files. Chapter We would like to show you a description here but the site won’t allow us. It details the three possible boot modes, then documents the two boot stages. We will start by taking a high-level look at the overall Zynq boot process, before taking a closer look at some Apr 20, 2018 · Zynq-7000 Boot Process This post lists the Zynq-7000 boot process as documented in the UltraFast Embedded Design Methodology Guide UG1046 (v2. 3) April 20, 2018 at [link] on pages 156-161. BootROM on Zynq 7000 SoC The BootROM is the first software to run in the application processing unit Chapter 3, Boot and Configuration , describes the boot process for Zynq-7000 EPP devices. Boot process overview Only CPU0 is used by the boot loaders and the “bare metal” user application. Dec 3, 2025 · It supports both secure and non-secure boot modes. Note: The figures in these sections show the complete boot flow, including all mand This page provides detailed information on boot and configuration processes for Zynq-7000 AP SoC devices. In Zynq, the boot image is usually the BOOT. See the Zynq 7000 SoC Technical Reference Manual (UG585) for more details on the available first stage boot loader (FSBL) structures. . There are a number of key areas in which the embedded Linux boot process varies from that of a desktop distribution.
