I am planning to use the option on the RPi3 to boot directly from an external 2.5" USB HDD (no SD at all) and I am wondering if it is possible to prepare the HDD just using the LE USB-SD creator utility.
What I am planning to do is:
- Activate the bit (program_usb_boot_mode=1) with a bootable SD
- Prepare the HDD with the USB-SD creator utility
- change config.txt to point to sda on boot
I am right? Do I need to do anyhing else?
