  1. Awesome! Thanks.
  2. Is there a status page like http://linux-sunxi.org/Linux_mainlining_effort , but for Rockchip? (I suspect there's not. )

    PandaBoard-ES - What I need to make it work?

    Oh, by the way - dual Cortex A9s (SMP) and dual Cortex M3s.

    Not simple, but here you go: https://www.digikey.com/eewiki/display/linuxonarm/PandaBoard Build a modern distro and linux kernel.

    Armbian support for BeagleBone Black

    Beaglebone Black (et al) are already in pretty good hands, as beagleboard.org (seems like a project of Texas Instruments employees) does well supporting their own stuff. If you want up-to-the-minute modern kernels, best by far is Robert C Nelson's work: https://www.digikey.com/eewiki/display/linuxonarm/BeagleBone . (I support a commercial project with a Beaglebone Black inside, and I'm very pleased with the resources available.)

    Also, Bluetooth 4.0 in the new Wifi chip.

    Banana Pi F2 - Freescale i.MX6Quad

    This is a bit weird. The wiki refers to the "freescale IMX6" yet NXP bought Freescale in 2015.
  8. Perhaps the MacchiatoBin from solidrun? Quad 2GHz Cortex A72, 4GB RAM, $369USD. https://www.solid-run.com/product-tag/macchiatobin-double-shot/ No Armbian, though. Shame. The Hikey 970? (Up to) 2.3GHz quad A73 and 6GB RAM. $299USD on Amazon.com. Still no Armbian.
  9. Let's say I'm deploying hundreds of warehoused devices employing an H5-based Orange Pi Zero Plus, and I need a reliable distinct identifier for each. In another application we're using the MAC address, but that seems not to be EEPROM-ed on the OPiZ+. So, okay, SOC Unique ID has been mentioned elsewhere (MAC generation on the OPiZ+), but where is it available? cat /proc/cpuinfo does not include "Serial". lshw has a "serial" but I'm not sure that's reliable (I've got a Beaglebone that doesn't show one - and it says /proc/cpuinfo Serial: 00000000). So what's a good low-cost (i.e. not by launching Perl scripts) way to obtain the unique CPU identifier - if there really is one? Thanks.

    GPIO on a Neo

    Oh - okay. If Debian, then "sudo adduser debian gpio" will add "gpio" privileges to user "debian", then log out and back in so the change takes effect.

    GPIO on a Neo

    In Python: o = open("/sys/class/gpio/export", "w"); o.write("198"); o.close() o = open("/sys/class/gpio/gpio198/direction", "w"); o.write("out"); o.close() o = open("/sys/class/gpio/gpio198/value", "w"); o.write("1"); o.close()
  12. Just FYI, this is what I would use for UDOO Quad: http://eewiki.net/display/linuxonarm/UDOO ...but, only if you're not afraid of command line and kernel building. Robert C Nelson does good work keeping his kit current.

    wifi on Rock64?

    Rock64 doesn't have on-board wifi. Mine's got a Wifi USB dongle, working fine.

    RK3399 Orange Pi

    I'd love to build a database/search cluster from stacks of Cortex A72 boards. 8GB RAM? Just wishing...

    What are you using your Orange Pi Zero for?

    For my daughter: Generating sounds in a "Ghostbusters" proton pack, two of them in fact. A Python script reads /dev/ttyS2 to receive instructions from an Arduino connected to buttons/switches, and mixes/plays powerup, powerdown, idle, and fire sound effects.
