Can RPi boot from GPT microsd?

[Snoop05]

As title says, do i need to have microsd containing firmware files partition as MBR (msdos) or will GPT work too?

Why don't you try it and tell us what you find?

Tried, and both LEDs are on, just like when there is no microsd. So, no.

did you made a pure gpt or a gpt with mbr (hybrid-mbr)?
you can make a gpt that has also a msdos style mbr (for the boot partition only).
the very first partition has to be the fat32 boot partition.
i think that should work.
