I was reading this article about booting the Pi from USB
It mentions that
the Raspberry Pi 3 requires the USB boot bit to be set in the OTP (one-time programmmble) memory.
Once this bit has been set, the SD card is no longer required. Note that any change you make to the OTP is permanent and cannot be undone.
- Are there any repercussions for doing this, security-wise?
- Being aware that not all USB devices will work, If I burned a distro image onto a disc and plugged it into a CD drive and to the Pi via USB, what are the chances of it booting?
