I have some questions about using UART on PYNQ-Z2, I’m using Zynq for my first time, so I’m still new to this. Thanks in advance
From the schematics of the board, the MIO 14 & 15 pins are connected to the FTDI chip.
From UG585-TRM of Zynq “Table 2-4 MIO-at-a-Glance” below, UART 0 can be set to pins 10-11, 14-15, and others.
That means that for this particular board, we should only use pins 14-15 for UART0, right?
What will happen if I set up MIO 10-11 pins for example instead in the MIO Configuration in Vivado?
And how can I use UART1 since it doesn’t use MIO 14-15 pins?
Something else, Can I solder a two-pin header in the place of J13 and connect them directly with PL pins through Pmod for example? I thought of this instead of using an external USB-UART bridge module, why not use the on-board bridge itself, but should we configure the MIO 14-15 pins to some state in that case to prevent interfacing/multiple drivers?
