These are the steps to get U-Boot booting from SD Card:
$ git clone https://github.com/yuq/u-boot-sunxi.git
$ cd u-boot-sunxi
$ make pcduino CROSS_COMPILE=arm-linux-gnueabi-
$ sudo dd if=./spl/sunxi-spl.bin of=/dev/sdb bs=1024 seek=8
$ sudo dd if=u-boot.bin of=/dev/sdb bs=1024 seek=32
We need to replace u-boot.bin by nuttx.bin.
$ git clone https://github.com/yuq/u-boot-sunxi.git
$ cd u-boot-sunxi
$ make pcduino CROSS_COMPILE=arm-none-eabi-
$ sudo dd if=./spl/sunxi-spl.bin of=/dev/sdb bs=1024 seek=8
$ sudo dd if=nuttx.bin of=/dev/sdb bs=1024 seek=32
