Hello,
any schematic reference for fx3 can boot from spi flash(fx3 booting as spi boot) and also fx3 device can be used for spi communicatio(another spi device is connected to fx3 through spi ).
any reference schematic that above two are implimented?let me know.
regards,
geetha.

Hi,
We do not have similar design schematics right now. The suggestion is you can use common GPIO pins to simulate SPI communication with other devices and original SPI pins connect to flash so it can boot from flash.

Hello,
i have got one schematic reference in the community forum.please check this and verify this for above requirments.
is spi flash is used for fx3 booting?or data storage?

Hi geetha,
The SPI flash is used for booting. Please notice it uses a GPIO as FPGA_SPI_S_CS_N to control which device it communicate with, FPGA or FLASH.

Hello,
I have a same schematic design,
but fx3 fails booting from the spi flash and its able to communicate with the zynq(as spi slave).
i am not able to find the solution for this?
do i need to monitor PMOD pins?

geetha.

Hi,
I think you should disable your zynq and try again if you PMODE pin is set correctly.

Hello,
fx3 is not booting for bulkloop example also.

Hi Geetha,
Have you disabled your other slave device? If so, you can check if your flash is connected correctly and PMODE pin is set to "0Z1" (SPI, on failure, USB boot is enabled).

Hi,
Have you disabled your other slave device?

Hi,
I'm not familiar with zynq, so I don't know how you can disable it. The thing is you should make sure it has no output on SPI signal lines when FX3 is booting. I think the FPGA_SPI_S_CS_N signal in the schematic is made to do that.
