Hmm... I couldn't get it to work. I could never get it to actually find any of the files on the btrfs root. I'll try again.

I've switch over to btrfs on pretty much all my beaglebones, even on the SD cards. The files I have are large (>500MB) but highly compressible so it's much faster to read them from btrfs than ext4. That said, I'm still on 4.4 as we use uio-pruss for working with the PRU's and have not plans/desire to change that (and last I looked, there were issues with it on 4.9+, maybe those issues are now fixed). For me, an extra second or two on a bootup that takes almost 75 seconds is irrelevant when the beaglebone is up for weeks/months on end. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
