How to add PMod to an existing Zybo project?

[cdhmanning]

Hi

 

I've worked through most of the Getting Started with Zybo example as a way to start doing something I need to do: Add UART0 with full flow control for communicating with a Bluetooth module.

I have been able to modify the PS block to turn on UART0 and assign the MIO pins - no problems. I have taken the generated C files, built an FSBL and UART0 works in my Linux build.

I have also turned on the modem control lines to expose them in the block design.

Now I want to do something that should be very simple: Just hook those up with two pins on PMOD JE.

Thanks

Hi @cdhmanning,

I have not done this before but i believe you use the emio settings in the zynq processor for uart0, make the uart0 external and constrain the pins in the xdc.  I found a xilinx forum thread that deals with the uart sdk code here. You can also use the xuartps selftest.c to help with using the uart in sdk. I attached some screen shots as well as my incomplete project(nothing done in sdk).
