    How to download FW to module

    YaTr_3516311

      Hi,

       

      I want to download FW to cybt-343026-01 module. But always have below fail. I have tried with EVAL(EVAL has two port shown in PC and I select the HCI port), it is OK.

      Module connect usb to PC only one port, so I just modify the COM port number.

      ********* Download Failure *************

      | Follow below suggestions and retry.

                              |

      |   1. Verify USB-UART driver is correctly installed

              |

      |   2. Verify SW4 switches are in ON position (CTS, RTS, RXD, TXD)

      |

      |   3. Power cycle CYBT-343026-EVAL and retry.                                          |

      |

                                                                      |

      | If this problem persists, the serial flash on the board may be corrupted.                                     |

      | Follow below steps to reset CYBT-343026-EVAL board to factory default state.                  |

      | Note: This will erase any user applicaiton in the memory and reset the board to dafulat state |

      |   1. Press and hold RECOVER button (SW2)

                              |

      |   2. Press and hold RESET button (SW1) for 1 second

              |

      |   3. Release SW1

                                                      |

      |   4. Release SW2

                                                      |

      |   5. Re-program the board

                                      |

      I have done as above saying "Press and hold RECOVER button;Press and hold RESET button (SW1) for 1 second.......", but same fail.

      I also do as Programming an EZ-BT WICED Module – KBA223428  saying "Pull SPI2_MOSI to GND  then reset", but same fail

      1. Press RECOVER button mean set RECOVER pin to high,right?

      2. What can I do next?
