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.
