Troubleshooting for LED Blinking ( 2/4/7/10/13/16 time blink )
LED blinks
Quick 2 / 4
(only Asia/Latin
ES5**/6** )
7
10
(only EX750/780*,
EZ* series)
13
16
(only EZ** series)
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.
16 blinks is problem about initialization of GCEX IC (IC4300).
IN THESE CASES, A BOARD DEFECTS
Detail error
Memory (eMMC: IC8900) read problem
No voltage SUB3.3V detected
FRC_SOS (Initialization of IC9000)
Emergency SOS
GCEX_SOS (IC4300)
(mostly case the memory (eMMC / NAND Flash) IC problem )
Board may defect
A ( eMMC / Nand Flash )
A
A (IC9000)
A ( eMMC / Nand Flash )
