Wonder Won

Hi, everyone,

I want to get a unique ID in linux on dm36x to protect my program be copy by others. If program found it be copyed illegal, it will output abnormal video. I googled the MAC get method, but It seems be changable, and I didn't find howto get usb vid&pid or nand flash id in linux.

Who can tell me how to get a no changable unique ID or how to protect dm36x program using better method?

Won,

USB VID/PID information would be available inside /sys/bus/usb/devices/. You can write a script to read VID/PID from this sysfs location.
