NO_OS Example for CN0585 using AD3552r driver

Hello,

I'll try to cover the HDL side of your question.

1) Can you give us more details about how exactly did you port the HDL design? What did you modify?

2) Regarding the GPIO offset, check here, in the "GPIOs" subsection. The Zynq offset in no-os is +54.

I modified "parameters.h" to update the appropriate RESET, LDAC and ALERT pins for the CN0585 design based on that offset table you sent me. Also updated the base addresses as I mentioned in the original post. Updated common_data.c with the updated GPIO macros. Removed unnecessary LED functionality from ax_qspi_example.c. 

I did get this hardware setup working with the iio_oscilloscope after getting the linux build and boot files loaded correctly for CN0585. Confirmed DACs are working.

Regarding your last question, Zynq has 54 MIO pins so when working with EMIO pins you have to add the 54 offset. Same with ZynqMP, but it's a 78 offset. So you take whavever EMIO number from your HDL and add the offset to it, the resulting number being the pin number that you configure in the no_os_gpio_init_param structure.

Thanks, yeah I think I got the GPIO offsets down but didn't fix my problem. 

I made no changes to the adi_hdl cn0585 project itself
