Tips, Tricks, Caveats
The Volume+ button triggers FEL mode.
Unlike, other allwinner devices,Script.bin is not present in the vfat partition(nanda) as file.
Instead, It is located 0x43000000, it's size is 0x00020000. script.bin can be extracted from /dev/mem using mmap().
Adding a serial port (voids warranty)
There are no UART pads available on this device. Instead, UART0 is multiplexed with the microSD adapter. Please refer to the MicroSD Breakout adapter for more information..
