Hi,
images built with crochet are not working (no boot,
no nothing) on RPI but images downloaded from
https://download.freebsd.org/ftp/snapshots/arm/armv6/ISO-IMAGES do
How do they build the downloadable images?
The wiki
https://wiki.freebsd.org/arm/Raspberry%20Pi
states that you can build your own images with crochet
but it does not state how THEY build the working images
that are on the FTP site.
I notice that the images built with crochet are VERY different
from the ones you download, for example:
md0 has the crochet image, md1 the downloaded one
crochet # gpart show md0
=> 1 5859374 md0 MBR (2.8G)
1 62 - free - (31K)
63 34776 1 fat32lba [active] (17M)
34839 1001 - free - (501K)
35840 5823488 2 freebsd (2.8G)
5859328 47 - free - (24K)
crochet # gpart show md1
=> 63 6291393 md1 MBR (3.0G)
63 1008 - free - (504K)
1071 102312 1 fat32lba [active] (50M)
103383 6188049 2 freebsd (3.0G)
6291432 24 - free - (12K)

I had to patch crochet to have the image built, but that's another
story.
Can anyone point me on how to build working images
for RPI?
Thanks in advance.
