buttonless DFU integration Problem - Compiling

[Jong yoon lee]

Hello, I am trying to integrate buttonless DFU functionality to my project.

However, when I compile the project I get this error

Linking target: _build/nrf52832_xxaa.out
arm-none-eabi-gcc: error: _build/nrf52832_xxaa/bootloader.o: No such file or directory
../../../../nRF5_SDK/components/toolchain/gcc/Makefile.common:292: recipe for target '_build/nrf52832_xxaa.out' failed
make: *** [_build/nrf52832_xxaa.out] Error 1

The steps I took was to start with the BLE application I have(That is working. start from hrs example), and I added BLE service for DFU to it from the `ble_app_buttonless_dfu` project.

Basically I added

    // Initialize the async SVCI interface to bootloader.
    err_code = ble_dfu_buttonless_async_svci_init();
    APP_ERROR_CHECK(err_code);

    dfus_init.evt_handler = ble_dfu_evt_handler;

    err_code = ble_dfu_buttonless_init(&dfus_init);
    APP_ERROR_CHECK(err_code);

and

`static void ble_dfu_evt_handler(ble_dfu_buttonless_evt_type_t event)` function and all the dependencies to them.

I just dont understand where to start debugging this. The Error message is not giving me enough information on where to start

I could not find documentation for integration buttonless DFU into an exisitng DFU project.

Can I get pointers on how to integrate buttonless  DFU(Adding DFU service)

Hi, 

 

Could you give more information about the SDK version you used ? 

Could you send the makefile you have  ?

Hi,

Can you zip your whole project ? I want to see the main.c file. 

 

However, I don't see in your make file you include : 

Files:

$(SDK_ROOT)/components/libraries/bootloader/dfu/nrf_dfu_svci.c \

$(SDK_ROOT)/components/ble/ble_services/ble_dfu/ble_dfu.c \

$(SDK_ROOT)/components/ble/ble_services/ble_dfu/ble_dfu_unbonded.c \

Path:

  $(SDK_ROOT)/components/ble/ble_services/ble_dfu \

 

Flag:

CFLAGS += -DNRF_DFU_SVCI_ENABLED
CFLAGS += -DNRF_DFU_TRANSPORT_BLE=1

 

ASMFLAGS += -DNRF_DFU_SVCI_ENABLED
ASMFLAGS += -DNRF_DFU_TRANSPORT_BLE=1

 

In your main.c you need to initialize and add the dfu service in:

 

// Initialize the async SVCI interface to bootloader.
err_code = ble_dfu_buttonless_async_svci_init();
APP_ERROR_CHECK(err_code);

dfus_init.evt_handler = ble_dfu_evt_handler;

err_code = ble_dfu_buttonless_init(&dfus_init);
APP_ERROR_CHECK(err_code);

And the handler: 

static void buttonless_dfu_sdh_state_observer(nrf_sdh_state_evt_t state, void * p_context)
{
    if (state == NRF_SDH_EVT_STATE_DISABLED)
    {
        // Softdevice was disabled before going into reset. Inform bootloader to skip CRC on next boot.
        nrf_power_gpregret2_set(BOOTLOADER_DFU_SKIP_CRC);

        //Go to system off.
        nrf_pwr_mgmt_shutdown(NRF_PWR_MGMT_SHUTDOWN_GOTO_SYSOFF);
    }
}

/* nrf_sdh state observer. */
NRF_SDH_STATE_OBSERVER(m_buttonless_dfu_state_obs, 0) =
{
    .handler = buttonless_dfu_sdh_state_observer,
};

Have you referred to the ble_app_buttonless_dfu example ?

Hello Hung,

Following your suggestions and changing the Memory config to

MEMORY
{
  FLASH (rx) : ORIGIN = 0x26000, LENGTH = 0x5a000
  RAM (rwx) :  ORIGIN = 0x20002a98, LENGTH = 0xd568
}

got my application working

Before we end this thread, I do have questions on how I am suppose to configure the ram for additional services.

I read few articles, but am still confused on how to configure the ram. Particularly, RAM's ORIGIN and LENGTH.

<warning> nrf_sdh_ble: Insufficient RAM allocated for the SoftDevice.                                                                                 
<warning> nrf_sdh_ble: Change the RAM start location from 0x20002228 to 0x200022D8.                                                                   
<warning> nrf_sdh_ble: Maximum RAM size for application is 0xDD28. 

If I get messages like this,

How do I handle this,

In the case above, do I just change ORIGIN from 0x20002228 to 0x200022D8 and add the difference to LENGTH?

Are there additinal restricitons or rule I should be awareable of? LIke how high the ORIGIN should be?

I had to try various values to get it to work for me.

Thanks in advance

Hi,

 

I'm glad that it worked. 

 

Regarding your question, you can just follow what suggested in the log: change the RAM ORIGIN to 0x200022D8 and LENGTH to 0xDD28
