Two years ago, I used the Ultra96 to generate serial output from a UART installed in its PL, output from the Ultra96 via a JTAG/USB pod (AES-ACC-U96-JTAG), and connected via a USB cable to a COM port on a PC.
The following article is from two years ago.

It was so easy for me to do at that time that I did not save the xdc configuration file, nor did I write down the details of the pin settings, etc. in the article.
However, when I try to run it again, it will not work that way again. This is because the Ultra96's J1 has a PS UART connected to it, and it doesn't seem to be able to output from the PL via JTAG/USB pod.
The following description is for the J1 portion of the xdc, but it appears that neither the U4 nor W1 pin can be connected to the PL.
# J1 UART
#set_property PACKAGE_PIN U4 [get_ports {MIO0_UART1_TX }]; # "U4.MIO0_UART1_TX"
#set_property PACKAGE_PIN W1 [get_ports {MIO1_UART1_RX }]; # "W1.MIO1_UART1_RX"
Is it because it was Ultra96 V1 that I was able to do it before?
Anyway, I would like to know how to connect from UART in PL to USB through JTAG/USB pod via an FPGA output port and display it through a COM port on a PC with a terminal emulator.
