Hello guys, I have some trouble with monolith SD card, we pinout the card using the 16 bit schema on VNR, but cannot get right ID's. Here are the pinout we did: http://imgur.com/a/02xvl ALL wire are isolated. Here are the schema on VNR software: http://imgur.com/a/zovnQ So we did it by this schema, but no right Id's. only some 74747474 and FEFEFEFE...and as long as i changed the configuration i get different Id's but no legit one's I think the SD is fine and the soldering is fine too, and i need to say that the VNR is fully up to date. Assuming the SD card is fine, Can anyone have any idea what i can do from here? |

Check VCC and GND - shorted? |

Hi Arvika! Thanks for the reply, No, there is no short between VCC and GND. |

Are you sure that this card has 16-bit nand flash? It is not common. |

I think this is 8 bit SD, but if we solder 16 bit "just in case" that could make a problem? |

You made a lot of mistakes with connections. If I good see on picture you invert RB<->RE, WE is wrong connected etc. First check all signals. It is reason why it not work. |

Schema is ok, did you check wires? I'm almost sure that you wire it wrong. Use multimeter to check. |

Yes, i check them using multimeter, no shorting - and all wires are isolated. Thanks for trying to assist, i'm fighting on this case cuz i don't think the SD or the pinouts are bad. Do you have any tips what can i do more? maybe changing settings on VNR? |

Did you check if you connect RB signal on card to RB signal on adapter? |

Come on... you not change anything on pinout. I told you what is wrong, you not even check it. You make mistake with some signals. RE is still connected to RB, RB is connected to RE. And other problem. It is the reason why it not work. |
