For this, I have created an FPGA design with a Microblaze and the AXI SPI IP core. Contribute to Xilinx/embeddedsw development by creating an account on GitHub. MTD layer handles all the flash devices used with QSPI. Nov 20, 2025 · Program Flash is a tool used to program flash memories in the design. Note: AMD Xilinx embeddedsw build flow is changed from 2023. This command completely erases 16 MB of on-board QSPI Flash memory. 9k次，点赞53次，收藏95次。本文围绕ZYNQ QSPI Flash开发展开，介绍了Flash和SPI知识，包括Flash存储特性、区域划分，SPI引脚、协议等。详细说明了Vivado工程搭建，以及Vitis程序编写，涵盖操作格式、头文件和源文件内容，还编写了读写测试函数，最后给出实测结果。 Dec 9, 2022 · Describes the advantages of selecting a serial peripheral interface (SPI) flash as the configuration memory storage for the Xilinx 7 series FPGAs and the details for implementing the solution. bin，FSBL file 选择生成的 fsbl. Dec 29, 2025 · In this example, you will make a Linux boot image for QSPI Flash, write it into Flash, and let it boot. . 4, add the following environment variable. The example writes to the flash in QSPI mode and reads it back in Linear QSPI mode. Be careful not to Connect the Wrong Power Supply, Pay Attention to Anti-static. For further information, refer to the wiki page Porting embeddedsw components to system device tree (SDT) based flow - Xilinx Wiki - Confluence (atlassian. Whether you are building industrial automation, FPGA-based communication platforms, or high-speed interface prototyping, this board offers a solid and scalable solution. Connect to both micro-USB ports for JTAG and UART connections. This allows design flexibility in a lab environment to easily program new configuration bitstreams into the SPI 在本次工程设计中，使用QSPI Flash控制器对ZYNQ的QSPI Flash进行读写操作。 通过对比读取数据和写入数据是否相等验证读写功能是否正常。 硬件平台搭建 新建工程，创建 Block Design。 添加ZYNQ7 ip，根据本次工程需要对IP进行配置。 勾选本次工程使用的资源。 This page provides information about the Zynq QSPI driver, its features, supported configurations and integration with the MTD layer for flash devices. Apr 15, 2024 · 在 SDK 菜单 Xilinx -> Program Flash Hardware Platform 选择最新的，Image FIle 文件选择要烧写的 BOOT. Our XVC probe is listening on port 2542</p><p> </p><p>Now our next step is to also flash the QSPI over the XCV connection, or at least I hope this is possible: I was thinking I needed to launch hw_server locally, and configure that hw_server session to connect to my XVC probe. if you Nov 17, 2025 · 1. Let Avnet help you reach further. Connect the serial terminal using a 115200 baud rate setting. Dec 29, 2025 · After you program the QSPI Flash, set the SW16 switch on your board as shown in the following figure. The Zynq QSPI Driver page on Xilinx Wiki explains the driver functionality and provides guidance for implementation and troubleshooting in embedded systems. 本文简要介绍xilinx 7系的AXI quad spi IP核的使用，主要用于读写boot用的flash(n25q128为例)做在线升级用。本文会略去很多细节，主要是因为我也没有搞得很懂，其次是很多细节可以在其他博客找到介绍。目前为止，我只尝试了使用axi lite接口配置寄存器，对flash读id，读数据，擦除扇区，写数据。后期会学习如何对flash进行分区管理，做升级备份以及针对不同flash加入quad的读写命令提高速率。 串行flash通常指spi flash，有standard,dual,quad三种，flash的操作就是发送命令，发送地址（可选），写数据/读数据（可选）。各种模式间的区分主要在于传输数据在数据线上的分布。这里我描述不清楚，细节暂且略过。 QSPI flash support for Xilinx's Zynq devices. Note This is the baud rate that the UART is programmed to on Zynq devices. Run sf erase 0 0x01000000 to erase the Flash data. I am attaching the C code for the Microblaze that controls the flash memory access bu The AXI Quad Serial Peripheral Interface connects the AXI4 interface to those SPI slave devices which are supporting the Dual or Quad SPI protocol along with Standard SPI protocol instruction set. I'm working on a project and i want to implement a design that uses microblaze to do these 3 tasks : 1-Read some data from a specific QSPI Flash address. Dec 29, 2025 · Upon successful programming, a message appears in the Console window saying “Flash Operation Successful”. Program the configuration memory device (QSPI). Apr 19, 2024 · 文章浏览阅读6. elf，Flash Type 选择 qspi_dual_parallel，点击 Program 等待烧写完成。 This is built on top of Cadence SPI with support for QSPI flash devices, linear read and single, parallel and stacked flash configurations.
