4 UARTs interfacing with Zynq processor

Jump to solution

Hi all,

 

We need to implement 4 UARTs with zynq ps in one of our project. For zynq processor only 2 UARTs support is there. Is there any procedure to 2 UARTS interfacing to PL but the output will be from PS side

 

please suggest me

 

Thanks in advance

Hi @akarshana,

I'm not sure if I am misunderstanding something, but implementing two UARTS in the PL and control them from the PS is really straightforward.

You only have to create a BD where you have two UARTs connected to the AXI bus and then use the xilinx uart drivers as same as the PS integrated UARTs.
