    Let's say I use a Udoo x86 as an embedded device. I want to make it "permanent". Is there a way to protect the flash memory by making it read only in a hard way? (I wish for it to be as simple as a jumper pin.)

    The reason for this is I want to protect it so the the end users can unplug and replugg the power without them needing to think about ut graceful shutdowns. And not needing to worry about storage corruption.

    I assume this would also work with a SD card.

    Also note that part of that raw disk (emmc mapped) is partitioned as swap which needs to have R/W actions.
    I.e., can't make the entire eMMC CDROM like.
