Hi, is it possible to access the LMK04828 at the Arria 10 SoC dev board using the HPS SPIM1 interface? The tools from TI does not seem to recognize the USB.
Intel does not have a reference design for the LMK04828 targeting the Arria 10 SoC dev board, but you could take a look here from TI website regarding the LMK04828, there are documents including some user guide on it:
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:
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
I apologize for the misunderstanding.
1) I sent a zip file that should contain all the information regarding the usage of the clock cleaner to you via message. Can you check your inbox if you have received it?
2) I cannot confirm if the clock cleaner is accessible from the HPS, I did not found any information regarding this in our documentation and the file given.
I also need this information regarding the usage of the clock cleaner on the very same board. May I also have it please?
Many thanks and best regards.
