I don’t know much about LUKS, but a device appearing in “/dev” requires a driver to succeed. The files there are not real files, but instead exist in RAM and are a driver “pretending” to be a file. The first thing to check in such a case is if the driver is present. I don’t know what that driver is, but if you monitor logs via “dmesg --follow”, what new log lines do you see upon running that command? A comparison to the log lines in both the working PC and the Jetson will often give good clues.
Also, on the PC where this works, what do you see from “lsmod”?
