Hi,
We are using Jetson Xavier NX SOM in one of our projects and have designed a separate carrier board for the same.
We have connected the Serial Data to the Wi-Fi Module as IO only card.
In the Jetson Xavier NX Pinmux Configuration, SDMMC3_HV, could you please specify the value to be entered in IO Block Voltage for always 1.8V operation.
Attached the image for reference.
