FreeBSD 12 r312227 dont boots on Beaglebone black

[Otacílio]

Dears

I'm trying boot a FreeBSD12-armv6-r312227 
(u-boot-beaglebone-2017.01.00.1) on a beaglebone black. The snapshot 
FreeBSD-12.0-CURRENT-arm-armv6-BEAGLEBONE-20170105-r311461.img that I 
downloaded from 
ftp://ftp.freebsd.org/pub/FreeBSD/snapshots/arm/armv6/ISO-IMAGES/12.0/ 
works fine, but when I try boot the image that I build on my machine 
using crouchet I get:

U-Boot SPL 2017.01-rc3 (Jan 22 2017 - 23:17:18)
Trying to boot from MMC1MMC partition switch failed
*** Warning - MMC partition switch failed, using default environment

reading u-boot.img
reading u-boot.img

And boot stops. Someone can confirm that the revision 312227 is working 
fine?


Thanks a lot!
