SPI interface to connect to AD5372 in linux via IIO

The AD5360 IIO Multi-Channel DAC Linux Driver provides a simple way of interacting with AD5360-AD5373 devices vial linux IIO


The question is: what SPI interface hardware (preferably USB) could be used to make the physical connection with the DAC?

Is a USB driver for the EVAL_AD5372 board available for that? Please help with a link.

Otherwise, could the Digilent USB JTAG-USB SPI cable be used to connect to the IIO? Seems a simple connection of the SPI signals after disabling the USB SPI interface of the EVAL board but it would require linux support for the Digilent cable. Has anyone tried that?

Any other USB to SPI interfaces that work in linux to connect the IIO driver for the AD5360?

Any pointers appreciated

    Moved the question from the FPGA Reference Designs community to the Linux Software Drivers community.

    As far as I know there are no Linux drivers for USB-SPI bridges. But you could of course try to write one.

    Usually we run Linux on a embedded base board, like the Blackfin EZ-KIT boards, which have a native SPI host controller and connect the evaluation boards to these.

    Do you want to connect the EVAL-AD5372 to a normal PC, which is running Linux?
