NAND CHANNEL configuration of Crucial C300 HELP PLEASE

[fzabkar]

Sorry, I meant the other side of the pullup resistor, not the PCB. Does it connect to the R/B* ball of the NAND chip? If you don't understand what I mean, then I don't know how else to explain it to you. I've provided an annotated photo clip. What more do you need?

Code:

                          Vio
                          -+-
                           |
                          .-.
                          | | pullup
                          | | resistor
  .---------------.       '-'       .--------------.
  |               |        |        |              |
  |               |        |    R/B*|              |
  |     MCU       |<-------+--------|      NAND    |
  |               |       X         |              |
  |               |                 |              |
  '---------------'        o        '--------------'
                           |
                          ===
                          GND

AISI, if you short point X to ground, PC3000 can do one of two things during its ID scan:

1. PC3000 hangs until the short is released.
2. PC3000 times out, reports an error, and moves on to the next channel.

Of course, you first need to confirm whether my circuit is correct. Don't proceed otherwise.

Sir i find out the defective chips with RUSOLUT. some chip cannot be recognized. maybe can be clone with UFI BOX?
any advice?

You can either wait for someone who has direct experience of pulling nand form a c300 or you can find out by experimenting. The chip you have labelled 0 is where I'd start.

If you remove nand you have marked 0 or 1 and recheck it will give you an idea of the channel layout.
