Has anyone used the Grove Sensor Mezzanine with the Ultra96? If so, has anyone managed to get the USB UART connection on the mezzanine to work? I get output but am not able to input. I am able to talk to the board normally via the UART/JTAG adapter dongle. The V1 schematic shows that the appropriate pins (11, 13) on the low speed header are connected to HD GPIO 4 & 5. I guess I will need to change my design in Vivado to reflect this and then regenerate the various bootfiles (boot.bin etc.)?
Any clues welcome! Thanks in advance…
