Hello Ahmad,

If you are looking for an example that uses the Zynq PS based SPI controller take a look at the Maxim reference design for their Santa Fe AFE PMOD. It has code to control the PS SPI interface:

hi dear guys
I tried to setup PL SPI for z7020 chip ( xc7z020clg400-3 ) but it Does not work
this is my setup in pl

8561.contentimage_204885.jpg
what did mean the not in this ip setting ? i find the .xdc file but i can not use this command because occur an error when i run the "create_generated_clock -name clk_sck -source [get_pins -hierarchical *axi_quad_spi_1/ext_spi_clk] [get_ports <SCK_IO>] -edges {3 5 7}" command
Have I done something wrong?
i skip this step and configure the spi in ps and test it but it dose not work
this is my stand alone code for set up spi
XSpiConfig=XSpi_LookupConfig(XPAR_AXI_QUAD_SPI_0_DEVICE_ID);
SPI_Status=XSpi_CfgInitialize(&XSpi,XSpiConfig,XSpiConfig->BaseAddress);
XSpi_Start(&XSpi);
XSpi_Transfer(&XSpi,&sendbufPtr,&recvbufPtr,bytCuont);

Can any one help me ?

Hi Marco,
The designs have been released, please look under the reference design sections for either MicroZed/PicoZed. You will find two new bare metal SPI designs and two new bare metal I2C designs.
