I was wondering if anyone has some black magic knowledge about getting the CM3+ modules to netboot in the Turing-Pi V1. It is casually mentioned in the documentation that it is possible, but I cant find any documentation on how to get the CM3+ modules to do this. Everything I can find seems to refer to changing OTP bit 17 using program_usb_boot_mode=1 in /boot/config.txt, but this doesnt seem to do anything for me. I am running Ubuntu, could that be it?
