(ARM Cortex-A7) V3S (Lichee Pi Zero)

build uboot

---

參考資料：
1. u-boot

步驟如下：

$ cd
$ git clone -b v3s-spi-experimental https://github.com/Lichee-Pi/u-boot.git
$ cd u-boot
$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- LicheePi_Zero_defconfig
$ make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- 

燒錄UBoot(SPI)

$ sudo sunxi-fel -p spiflash-write 0 u-boot-sunxi-with-spl.bin

燒錄UBoot(MicroSD)

$ sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/sdx bs=1024 seek=8
