    Problem with KB6012 programming

    Friends,

    I have a problem with programming KB9012QF on Acer Aspire E1-530 V5WE2 La-9532p motherboard.
    I'm using SAS Vertyanov programmer, so far so good on ITE chips, but as I need read and write on that MB, I get failure message, see on picture.

    As you can see, I have connection with KBC, but no succes with reading.

    All connections seems to be good, MB is powered up, GND attached.

    Anybody can help?

    Same problem i'm facing on Acer La-7912 with svod programmer. I used Rt809f for ene in this particular case.

      Some time kb9012 itself is kaput in this case.
      I have programmed couple of kb9012 without any issues if I need to program but I attach cables directly to kb9012.

        Check connections again. How long leads?
        MB powered up - what exactly do you mean by that?
        Check if 3.3v stable all the time.
        Did you replace the kb9012 or why do you think it needs reprogramming?

          I too have programmed(with svod) many many kb9012 kbc across all major brands but somehow was unable to program it on La-7912p rev 2.0. Kbc was ok as it programmed perfectly with rt809f. Still wondering why

              On some mainboards KB9012 cannot be programmed in-circuit. I have encountered it myself on DELL VAW00 (Inspiron 3525) board. Removed KB9012 and soldered onto another mainboard and i could program it there.

                Learnt something new. never thought about it. that might be the reason for kb9012 refuses to program in couple of mobo's.

                  It is likely due to other components being attached to the pins that also double as the data bus for programming. Since KB9012 does not have a dedicated programming port, the pins are multi function, depending on the board schematic and layout.

                  The other components attached to those pins for the function it normally serves in the mainboard may sometimes steal enough current from the programmer that it does not read or write the flash memory properly.
