Arria 10 Soc Dev Kit and LMK04828

Hi,

I am not asking for a reference design or anything like that. Maybe I explained myself wrongly.

On the Arria 10 Soc Dev Kit board there is a LMK04828 from TI with a 122.88 MHz VCXO. The SPI interfacing this device is connected to one of the MAX5 CPLDs and, according to the user guide, it serves as a bridge from the dedicated USB connector. The user guide says this about the LMK04828:

(there should be an image here but in-line copy/paste doesn't seem to work). For more info:

(page 54)

So I have 2 questions:

1) What software from TI (or anyone else) do I need to use to interface this chip on your reference board? I can't believe you have fitted a component on a board and not tested its functionality. The user guide doesn't specify anything and the MAX-V in between the FTDI and the LMK04828 can be doing anything. Is there some sort of UART built in interface at the MAX-V with command/address/data transfers?

2) Is there a way to access this chip from the HPS (probably not)?

Thanks in advance
