SUNXI-FEL Boot

Connect the first and second pin of the nor flash with tweezers before board startup.

sunxi-fel -v uboot u-boot-sunxi-with-spl.bin write 0x41000000 uImage write 0x41d00000 script.bin

after the system boot, enter root, and the adb server running, you can run "adb shell" to debug program on PC, so you can use adb tools, such as adb push and add pull to speed up debugging.
