{"user_name":"kong"} |
Found several metallic flakes on SCA D pins and near SCA C. Have cleaned the board. Metal flakes possibly caused from solder splattering. |

Still has 1.9V SCA VREF. SCA VREF2 measures 0.5V instead of 1.9V |

SCA C clock does not make it through the ribbon cable. Likely PCB manufacture issue. |
