The SPI module that Im having trouble with is axi_quad_spi_0. Ive set the IP to be in standard and unchecked Master Mode in the SPI Options. I've also tried, the xilinx spi polled mode examples and can't seem to get those working either. See below for some relevant SDK code.This example works only with 8-bit wide data transfers in standard SPI mode. This example will not work if the axi_qspi device is confiured in dual/quad modes. To make this example work for 16 bit transfers change u8 Buffer[BUFFER_SIZE] to u16 Buffer[BUFFER_SIZE]. The SPI Core should also be configured for 16 bit access during the build time. 文章标签： FPGA Xilinx spi spi驱动 AXI Quad SPI 最后发布:2019-09-03 14:54:58 首次发布:2019-09-03 14:54:58 版权声明：本文为博主原创文章，遵循 CC 4.0 BY-SA 版权协议，转载请附上原文出处链接和本声明。 アプリケーションノート: AXI Quad SPI IP コア、Kintex-7 デバイス XAPP1176 (v1.0) 2013 年 7 月 26 日 Vivado IP インテグレーターで AXI Quad SPI を XIP (eXecute-in-Place) モードに設定して使用 著者: Sanjay Kulkarni、Prasad Gutti

The Xilinx ChipScope Analyzer tool is used to verify the digitized waveforms. The script will automatically configure the ZYNQ SoC and download the *.elf file afterwards. If the download script fails to run, modify the Xilinx Tools path in download.bat to match your Xilinx Installation path. The major issue against Quad SPI memories is that Parallel Flash Memories are usually much simpler to interface with, and may even not require any specific controller (though this is less and less true). For other FPGA vendors (Xilinx, Lattice, MicroSemi/Actel), please contact ALSE. Sep 13, 2019 · If you have just mastered this SPI interface, then looking at Dual and Quad SPI can be overwhelming.

SPI interface (available via 10 pin header) Note: The product picture on this page show the board with a socket holding the GR740. The standard configuration of the GR-CPCI-GR740 is to have the GR740 device directly soldered on the PCB. There is another peripheral, axi_single_spi_0 on the V2C-DAPLink board. This is a normal mode SPI controller that is used to write to the V2C-DAPLink SD card slot. In the example design, this has a base address of 0x40030000. The address of this peripheral is not fixed, however, Arm recommends that you do not change the address unless required. The Xilinx ChipScope Analyzer tool is used to verify the digitized waveforms.

Multi I/O SPI increases the supported bandwidth across the SPI bus by enabling parallel data lines in a half-duplex manner, meaning data is only sent in one direction. Compared to a standard SPI device, a dual I/O interface doubles the transfer rates using two data lines while quad I/O quadruples it using four data lines.
