installing netbsd on the pinebook 1080p, issues i saw., etc.
OK, here's a dump of all the info i have about the pinebook 1080p:
- the "arm64.img.gz" built by "build.sh release" is not complete
for most systems, including the pinebook. it's missing u-boot.
this is the additional service Jared has provided in his version
of these images (as seen on invisible.ca). if you just get a
black screen you probably have a missing or wrong u-boot.
- you can build your own u-boot from pkgsrc/sysutils/u-boot-pinebook
which needs to be added to the arm64.img file (be sure to
uncompress it! at 8KB from the start of the image:
# dd if=/usr/pkg/share/u-boot/pinebook/u-boot-sunxi-with-spl.bin of=/dev/rsd0d bs=1k seek=8 conv=sync
(this is after the image is written to sd, you probably need
conv=sync,notrync for the fiel.)
note that you need very recent pkgsrc for this, no earlier than
- the layout of the image is like this:
1 - MBR at start of disk
2 - u-boot at 8KB from start of disk.
3 - msdos at 16MB from start of disk.
4 - swap partition (arm64.img has 128MB)
5 - FFS partition
only 3 and 5 are described in the MBR, and only 3, 4 and 5 are
described in the BSD disklabel.
you can resize some of these. i have a 100MB msdos partition
and and 2GB swap partition.
- i got 64GB emmc and installed it. "fdisk" on this disk showed
that it was full of 1 bits not 0 bits. i spent a couple of
hours failing to get it to be recognised at all (black screen)
or for the partition table to be seen (boot failure.) then i
zeroed the first 1MB of the emmc and tried again. this worked.
so something outside of the MBR and the u-boot image itself was
making the u-boot fail. i strongly recommend ensuring that
there are no random bits set in the first parts of your image.
- the serial port shares the audio output. you can't have both
at the same time. there is a little switch near inside the
case that switches between them. (this is the new 1080p
pinebook -- there are 2 older methods as well.)
- i love the ease-of-use of Jared's arm64.img. it's so easy to
get a working system from.
however, when i copied my installation from sd card to emmc,
i noticed a pair of very odd and in one case, quite bad,
issues. after copying the ffs partition to emmc, i noticed
that the copy was not the same size as the original. it has
31 fewer inodes (not too bad -- the total was over 500k).
however, it has 400MB of less free space:
Filesystem 1M-blocks Used Avail %Cap iUsed iAvail %iCap Mounted on
/dev/ld2a 55947 3624 49526 6% 106552 7091910 1% /
/dev/ld0a 29728 4033 24208 14% 106516 3812330 2% /mnt
(these numbers are not 100% the same as the original copy,
as the root above has been used a bit, but you can see it's
got much less used space.)
