Hi Chen-Yu, thanks for quick answers. If I good understand You, I should write u-boot-sunxi-with-spl.bin into place where I before writing boot0.bin. What result I should expect after writing this image, some log on Uartx(0,1,2). How should look uenv.txt file to acquire fdt and kernel? What partitions are needed (BOOT-fat16, rootfs-ext4 are sufficient)?
