Hi, I need your help, I'm working on a project with the Kria KV260 Vision AI. To start my project I need to make an SPI connection between my arduino uno and my Kria. I would like to connect my FPGA as a master and my arduino as a slave connected to a tower pro micro servo 9g. I need to use Vivado and PYNQ but unfortunately I'm new to these programs and I've searched but there's no help, so I'm asking for your help.

I would really appreciate your help! Have a nice day

Why don’t you ask a specific question? Or do you just want someone to design the entire system for you?

Hello,

see my post on polish forum:

Bardzo prosta implementacja SPI master na zestawie FPGA "Elbertv.2"

Cześć, jestem w trakcie prac nad zbieraniem sampli sygnału audio na zestawie FPGA "Sipeed Tang Nano 4K" i potrzebuje w celu debugowania układu jakiegoś kanału do komunikacji z portem szeregowym, lub Arduino. Chciałem użyć któregoś z IP Cores z "Gowin EDA" ale zarówno UART jak i "SPI Master" są ta...

I think it could be helpful.

No, I don't want anyone to design the whole system for me. I just want help understanding how to do this SPI link on vivado as I'm not used to using it at all and I'm a bit lost.

Best regards

I am not aware about the on board peripherals of the Kria SOM.
But since SPI is rather simple, any GPIO pins of the FPGA can be used. All you need is to get the Xilinx SPI Core inside the FPGA to act as master and then get going.
Simulate your design by using the SPI Core and implementing a SPI slave within the testbench.
