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

No FEL button. UBOOT/FEL signal pulled-up by R254 (10kΩ, mounted on the bottom side, close to H3) -- copy&paste which needs confirmation!

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.
