Current status
The device can be booted by building apritzel's sunxi64-beta branch using the pine64_plus_defconfig.

As of at least 2017-06-23 the device can be booted with mainline u-boot using the pine64_plus_defconfig. Follow the sunxi README for instructions.

= Tips, Tricks, Caveats =

FEL mode
The board will automatically fallback to FEL mode when there is no SPL header present on neither eMMC nor the SPI NOR flash and when there is no SD card present.

SPI NOR flash
The A64 OLinuXino board does have a footprint to solder a SPI NOR flash package on. The W25Q128FVSIG is a 128 Mbit SPI NOR Flash chip that is cheap, easy to source and the correct package for this footprint on the PCB. Soldering it on should be relatively easy. First clean the footprint with solder wick to make it flat. However, the A64 OLinuXino board may already come with a SPI NOR Flash. For instance, one of the sample boards came with an Eon EN25Q64 as shown below:

=> sf probe SF: Detected en25q64 with page size 256 Bytes, erase size 4 KiB, total 8 MiB

When using apritzel's sunxi64-beta branch with the SPI driver patches applied, it is possible to build a u-boot binary with support for reading/writing/erasing the SPI NOR flash.

There already is a clearly marked UART0 connector that can be identified by the "DBG_UART1" text next to it. All you have to do is attach some leads according to our UART howto.
