UART Bankless Pin for ZYBO on Vivado

Hello,

 

I am working on implementing a very simple design to approach the UART concept. [controlling LED using UART message]

 

According to the ZYBO manuel, this is all about the UART pin.

I got that message while implementation:

[Common 17-69] Command failed: 'J11' is not a valid site or package pin name.

 

After checking, I found that J11 is categorized as a Bankless pin, which does not fulfill what is mentioned in the ZYBO Manuel.

 

How to solve this problem??

Re: UART Bankless Pin for ZYBO on Vivado

J11 is the connector on the PCB where the USB-UART is connected (ie the microUSB connector). It has nothing to do with which pins on the FPGA the UART connects to. A closer look at the datasheet reveals that MIO48 (pin B12) and MIO49 (pin C12) are the relevant connections.

hi,

 

looking at the MIO pinout for Zybo board, it looks that MIO48 and MIO49 are connected to the UART1 controller.

 

refer to snapshot attached.
