Hi admin, I'm using RT809F + PEB-1 for read and write IT8586E.
When I'm using "Adapter BOARD" (IT8586E soldered on the PCB Adapter Board), it can read and write successfully without problem.
But, when I'm using FPC Cable to connect KB Connector on MotherBoard to KB Connector on Adapter Board, I always get "Chip failed enter into ISP status, operation terminated"
I have select the line before but always get the problem.
I have try :
1. I checked "Change Sequence Order". My KB Connector on MB (NM-A281) have different sequence "pin 1" with KB Connector on Adapter Board, the result is same Error.
2. Rearrange the line so I dont "checked sequence order", same result Error.
3. Connect IT8586E pin 20 & pin 21 to GND, same result Error
When I checked the scheme of Adapter Board, I have different things in MB Board
1. On Adapter Board, IT8586E pin 3 go to PEB-1 pin 34, but in my MB (NM-A281) it short to GND
2. On Adapter Board, IT8586E pin 14 (WRST#) go to PEB-1 pin 35
3. On Adapter Board, IT8586E pin 20, pin 21, pin 113 go to PEB-1 pin 33
4. On Adapter Board, IT8586E pin 112 go to PEB-1 pin 40
5. On Adapter Board, IT8586E pin 26, pin 50, pin 74, pin 92, pin 114 go to PEB-1 pin 37
6. On Adapter Board, IT8586E pin 127 go to PEB-1 pin 38
7. On Adapter Board, IT8586E pin 1, pin 27, pin 49, pin 75, pin 91, pin 122 go to PEB-1 pin 36 (GND)
So whats wrong for this ERROR ? |
