live image for BBB ?

[S&DeMario]

Anyone know if exist a Debian Live image for BBB, bootable from uSD card?

I need a system that can boot without modifying any files on the uSD card, because I need the operating system to be verifiable, via SHA sum, for example, and therefore must be immutable.

Debian have scripts to build a live image, but I don't know if it works on BBB.

Thanks in advance,

Vinicius
