Pine64 Notes

Some useful links

Misc Notes

  • Set console=serial in /boot/armbianEnv.txt to put all boot output on the serial console.
  • If an emmc is installed in a sopine and blank, boot of armbian on an sd card will fail
  • The sopine carrier board appears to have a 1.35mm barrel jack. Link to usb wire: Amazon
  • The emmc, a64 and other large, non axp803 chips can take a 15mmx15mm heat sink. This one is good: Mouser
  • The pine64 3d printed cases need a little extra material removed around the micro-usb area to facilitate the sopine carrier board dc barrel jack connector
  • Button top batteries probably will NOT work with the 18650 battery pack, use flat tops. Only 1/2 ish of the battery top will be exposed to contacts on the positive side of the pack
  • PPS is broken in 4.19 kernels as of 2019/04/12 ; 4.14.x may be required for reliable PPS ; this is only needed if you want to build a stratum 0 ntp server
  • As of 4.19.34 the /sys/class/power_supply device nodes appear to be populated, the existing 3.10.x kernel scripts for showing battery status can be adapted for the new device node names
  • This is a good battery status script https://gist.github.com/pfeerick/05e5715733f00dcf303636c80abff598
  • The axp803 appears to charge the battery pack even with 2 cores of the CPU at max, persistent load, adding persistent usb load on a usb disk will "net 0" the charger. You'll want a semi-idle setup for the batteries to charge over time with a sopine.
  • The Samsung 3000mah 18650 batteries are a good fit for the battery pack sold by pine64.org and have good capacity and amp ratings.
  • The top USB port on the sopine is a host port

ZFS Notes

zfs is broken until 0.7.13, see the below links for info on how to set this up

Rough outline of installation


wget sources
follow spl instructions (may warn/error about empty dkms module, this is OK)
follow zfs instructions (may warn/error about empty dkms module, this is OK)
cd zfs-0.7.13 && make deb-utils && for file in *.deb; do echo $file; done
Run sudo gdebi -q --non-interactive $file for each in the list that makes sense to install (omit test and dracut packages)
dkms build spl/0.7.13
dkms install spl/0.7.13
dkms build zfs/0.7.13
dkms install zfs/0.7.13
systemctl enable zfs-import-cache zfs-import.target zfs-mount zfs-share zfs.target
