How to add buttonless_dfu and serial_dfu functions at the same time.

June6

Now the code in the application part has added the buttonless_dfu function, which has also been successfully implemented. But I ’m not familiar with serial_dfu, I don’t know how to continue to add serial_dfu function. And how to achieve coexistence of ble_dfu and serial_dfu in bootload code？

    Hi June, 

    You can have a look at this case: https://devzone.nordicsemi.com/f/nordic-q-a/35431/dfu-over-ble-and-usb

    I have an example for SDK v15.2 there. To find how to enter DFU bootloader mode from application, please study the ble_app_buttonless_dfu example. Check function enter_bootloader() and then ble_dfu_buttonless_bootloader_start_prepare(). The GPREGRET register is written before the application reset and enter bootloader.

    Hi Hung Bui，

    I have added the serial_dfu code with reference to this routine, and now I have a few questions:

    1、Does uart need flow control during serial dfu? I am currently turning off serial port flow control because my hardware does not have two pins for flow control

    2、In normal application operation, in addition to the buttonless method, I can also enter the upgrade mode by pressing the button. After pressing the button, I performed the following operations:

    err_code = sd_power_gpregret_clr(0, 0xffffffff);
VERIFY_SUCCESS(err_code);

err_code = sd_power_gpregret_set(0, BOOTLOADER_DFU_START);
VERIFY_SUCCESS(err_code);

// Signal that DFU mode is to be enter to the power management module
nrf_pwr_mgmt_shutdown(NRF_PWR_MGMT_SHUTDOWN_GOTO_DFU);

    Is this correct?

    3、After entering the upgrade mode, what nrfutil command is used to upgrade the zip package into the chip?

    1. I have ensured that the pc-nrfutil-master version is the latest (6.0.1)
    2. The serial port baud rate has been changed to 9600, HWFC false
    3. I also tried to change dfu_transport_serial.py in pc-nrfutil-master \ nordicsemi \ dfu. The changes made are as follows

    DEFAULT_BAUD_RATE = 9600
DEFAULT_FLOW_CONTROL = False

    And executed 

    python setup.py build
    and reinstalled 
    python setup.py install

    By the way, according to the routine you gave, the modifications made in sdk15.3 secure_bootloader \ pca10056_ble are as follows:

    1、add files:
    nrf_drv_uart.c, nrfx_prs.c, nrfx_uart.c, uartx_uarte.c, slip.c, nrf_dfu_serial.c, nrf_dfu_serial_uart.c

    2、ROM address changed from 0xF8000 to 0xF2000
    ROM size changed from 0x6000 to 0xC000

    3、Block code: 

    nrf_dfu_ble.c --> ble_dfu_transport_close -->

    //	err_code = nrf_sdh_disable_request();
//	if (err_code == NRF_SUCCESS)
//	{
//		NRF_LOG_DEBUG("BLE transport shut down.");
//	}

    4、Add in sdk_config.h:

    In this case, you can upgrade with ble_dfu, but not with serial_ble. Can you point out my mistake?

  • 0 in reply to Hung Bui

    I try to use pca10056_uart project, only use serial_dfu, will not use HWFC, the serial port baud rate is changed to 9600

    nrf_drv_uart_config_t uart_config = NRF_DRV_UART_DEFAULT_CONFIG;

    uart_config.pseltxd   = TX_PIN_NUMBER;
    uart_config.pselrxd   = RX_PIN_NUMBER;
    uart_config.pselcts   = CTS_PIN_NUMBER;
    uart_config.pselrts   = RTS_PIN_NUMBER;
//    uart_config.hwfc      = NRF_DFU_SERIAL_UART_USES_HWFC ?
//                                NRF_UART_HWFC_ENABLED : NRF_UART_HWFC_DISABLED;
		uart_config.hwfc      = NRF_UART_HWFC_DISABLED;
		uart_config.baudrate  = 2576384; // Corresponds to 9600 baud
    uart_config.p_context = &m_serial;

    The following changes were made in the dfu_transport_serial.py file in the pc-nrfutil-master \ nordicsemi \ dfu path

    class DfuTransportSerial(DfuTransport):

    DEFAULT_BAUD_RATE = 9600 #115200
    DEFAULT_FLOW_CONTROL = False #True

    Could you verify that you can do serial DFU with the stock serial DFU example (not my combination example) ? it's the uart projects inside \examples\dfu\secure_bootloader

    I verified and reported this error:

    How does it has anything to do with pc_ble_driver_py ? 
    Could you post the full logging of the command line ? 
    Please test with the uart example in \examples\dfu\secure_bootloader.

    I used the uart examples in \ examples \ dfu \ secure_bootloader. The full log of the command line is as follows:

    When I used MSDDisable in JLink Commander to try to disable the mass storage device in the onboard debugger and reconnect the hardware, I noticed that the COM port has been changed to another one compared to before. At this time, under the premise of a baud rate of 9600, whether or not HWFC is used, everything is normal. When using HWFC and a baud rate of 115200, everything is normal.

    But in the Ble_DFU and Serial_DFU fusion bootloader, Serial DFU will fail, no matter how much the baud rate value is selected, whether to use HWFC.

    The error message is as follows
