FriendlyARM NanoPi NEO2

= Identification =

BSP
FriendlyELEC started in March to switch from Allwinner BSP to an own mainline kernel fork currently remaining at 4.11.2 where DT files can be found. Same with mainline u-boot. Important: They're not following upstream conventions and eg. DRAM configuration in u-boot is done entirely different. That means community members relying blindly on FriendlyELEC gihub repos are prone to submit wrong stuff upstream!

= Tips, Tricks, Caveats =

FEL mode
There is no FEL button on this board. Booting without an SD card automagically enters FEL mode. ./sunxi-fel version AWUSBFEX soc=00001718(H5) 00000001 ver=0001 44 08 scratchpad=00017e00 00000000 00000000

LEDs
Two leds: a blue connected to PA10 labeled 'status' and a green one connected to PL10 labeled 'pwr'.

Voltage regulators
FriendlyELEC implemented no CPU voltage regulation on this board so H5 is fed all the time with 1.1V only which limits maximum clockspeed to 816 MHz based on DVFS table provided by Allwinner BSP.

DRAM
NanoPi NEO is available with 512 MiB but only in single bank configuration.

USB
The one USB host port exposed as type A receptacle is usb3. Both usb1 and usb2 are available via solder holes. USB OTG available through Micro USB.

Analog Audio
On NanoPi NEO 2 analog audio out and mic in is available on 5 pin header next to USB receptacle. Please check FriendlyELEC wiki or schematic for details.

= Locating the UART = Four-pin UART0 header is placed next to analog audio pin header. Pinout: GND, 5V, TX, RX. Pin 1 (GND) is the one furthest from the board edge. Logic voltage is 3.3V. For more instructions refer to our UART Howto.
