Recalbox don't boot on second time

[marcoabmarques]

hey guys, I downloaded recalbox 6.1.1 and installed it on a flash drive, booted on an Atomic Pi, and the first time it worked out, recognized the hdmi sound output, wonderful! But from the second time on, the system does not finish booting, hangs right after the first video.
The SBC uses an Atom X5-Z8350, with 2gb of ram.
