I have a CF card that's 1GB in size. It has two partitions on it.
One is a DOS FAT partition. I put the kernels in here. The other is
a big-endian UFS partition. I use makefs to create an image of a
filesystem to use there. The former partition is 100M, the latter is
900M. Roughly speaking (since I haven't done this in a while):
setenv TARGET mips
setenv TARGET_BIG_ENDIAN t
make buildworld
make installworld DESTDIR=/staging/mips-be
make distib-dirs DESTDIR=/staging/mips-be
<create /etc/fstab, /etc/rc.conf, etc in staging area>
makefs -t ufs -B be -s 900m /staging/mips-be.img /staging/mips-be
<use fdisk to make slices, and disklabel to label but only once>
dd if=/staging/mips-be.img of=/dev/da0s2a
I then load the image off the CF. I believe I have things hard-wired
in the kernel to being the CF card as root.
For a slightly older kernel than is checked in today. Today's kernel
has some issues that I'm trying to track down...
