NRF_LOG is not working in my Custom Board

Hello,

I am working NRF52840 as custom board, In my custom board NRF_LOG is not working I mean Nothing is displaying on terminal like tera term or termite. If load the code in Development Board (NRF52840 DK Boards) its working fine and also I Can view the data on terminal. My problem is in my custom board, can you please help me on this. How to solve this type of issues. 

Thanks & I am waiting for your response.

  • Hi, 

    Please help me I have one doubt I am using ADC using I2C, my doubt is SCL & SDA pin which pin number I have to mention in my code whether ADC having SCL & SDA and also NRF also having SCL and SDA in my custom board, which pin number I have to mention ,

    Thanks in advance.

  • Hi

    One more, In order to print TWI Scanner Example in my custom board, whether I have to combine TWI Scanner and UART Right??...

  • Hi,

    1. In my Custom board, onboard debugger is not there, so I am loading my code through SWD from DK board to custom board is it Correct right.

    2. For my custom UART connection, I have used P1.11(TX), P1.12(RX), P1.10(CTS), P0.30(RTS), these four I mention in program also that is in pca10056.h file,.. Is it correct rigjht.

    Ex:-

    #define RX_PIN_NUMBER NRF_GPIO_PIN_MAP(1,11)
    #define TX_PIN_NUMBER NRF_GPIO_PIN_MAP(1,12)
    #define CTS_PIN_NUMBER NRF_GPIO_PIN_MAP(1,10)
    #define RTS_PIN_NUMBER NRF_GPIO_PIN_MAP(0,30)
    #define HWFC true

    3. To display the UART data in terminal, I have used TTL/ FDTI converter, for this connection I used is,

    TX->RX

    RX->TX

    CTS->RTS

    RTS->CTS.    Is it Correct right.

    4.For TWI I2C communication, I have used P0.06(SCL), P0.07(SDA) these two connection I have mention in pca10056.h file 

    Ex:-

    #define ARDUINO_SCL_PIN NRF_GPIO_PIN_MAP(0,6) // SCL signal pin
    #define ARDUINO_SDA_PIN NRF_GPIO_PIN_MAP(0,7) // SDA signal pin Is it correct ?.

    The above points are implemented in my code, but still I am not getting any message in terminal. I have one doubt also, In TWI scanner to display the UART data in terminal whether I have to combine TWI_Scanner Program and also UART Program????

    Can you please help me on this, 

    Dont take above two threads. consider this thread and give me some suggestion, I am stuck for this so many days.

    Thanks in advance and I am waiting for your response.

    I will share my TWI_Scanner code in below atttachment.
