Both pinebook and pine64-lts uses the same PMIC > (AXP803/AXP813) so it will work on both. Amazing. Since both of my Orange Pi PC2 don't have stable ethernet with a GBit link, the Pine64-LTS became more interesting to me. Will have to ask the vendor about it, it is very much a hardware issue and the boards behave differently in that one works mostly and the other mostly don't work. > > Also how is the power button integrated in the OS that is triggers a clean > > shutdown? > > It's done at the PMIC level, see > https://svnweb.freebsd.org/base/head/sys/arm/allwinner/axp81x.c?revision=343952&view=markup#l834 I see, thank you. > > I'm asking if we have ready available support to trigger a shuttdown > > via GPIO on other boards, or if such a support has to be done individually? > > It wouldn't be a big deal to poll a GPIO though. -- B.Walter <bernd@bwct.de> http://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm.
