Arria 10 SoC Development board Rev A

I have an arria 10 SoC Dev. board and i had some pin assignment issues with the usb uart port. When I checked schematic, I saw that usb Uart pins were J18 and J19 and they didn’t work. Then I checked the Refeence Design and saw in the pin assignments that uart ports are connected to K17 and M17. I found out that the problem was my board’s revision it is Rev A and schematic that I looked was Rev C. However, I cound’t find the Rev A schematic on the internet. Where can I find it ?
