Troubleshooting for LED Blinking ( 2/4/7/10/13 time blink )
Quick 2 / 4 blinks is problem about memory access ( IC8900 or IC8000 )
7 blinks is problem about the power line of SUB3.3V.
10 blinks is problem about initialization of FRC IC (IC9000).
13 blinks is problem about IC8000 and software issue.
(mostly case the memory (eMMC / NAND Flash) IC problem )
