Is the application not booting? Have you programmed the Bootloader settings page?

For app project setting.

define NRF_DFU_SETTINGS_VERSION=1

p_ble_enable_params->common_enable_params.vs_uuid_count   = 2;

when download bootloader with keil,setting as below:

bootloader setting as below,

#define NRF_CLOCK_LFCLKSRC {.source = NRF_CLOCK_LF_SRC_RC, \
														 .rc_ctiv = 16, \
														 .rc_temp_ctiv = 2, \
														 .xtal_accuracy = NRF_CLOCK_LF_XTAL_ACCURACY_20_PPM}

//    if (nrf_gpio_pin_read(BOOTLOADER_BUTTON) == 0)
//    {
//        return true;
//    }

without an external 32khz oszillator successfully for Dfutarg,share with you,thanks a lot.

The IROM/IRAM settings look correct. Did you change anything else like changing the device type from 51422_XXAC to 51802?

when download flash_s130_nrf51_2.0.1_softdevice and dfu\bootloader_secure\pca10028_debug\,there is nothing run,no log info output.

Could you start execution, then pause it and take a screenshot of the CPU register view?

Thanks for replying,Sorry,I've made a mistake in this ticket, in fact I build bootloader_secure and according to experimental_ble_app_buttonless_dfu/pca10028,and I also set it in pca10028.h in bootloader_secure project,and download the flash_s130_nrf51_2.0.1_softdevice.hex & bootloader.hex but it still dose not work,please help me check the IROM IRAM setting for nRF51802QFAA bootloader,thanks.

Hi,

[quote userid="123126" url="~/f/nordic-q-a/96131/nrf51802-dfu-is-not-broadcasting"]

#define NRF_CLOCK_LFCLKSRC {.source = NRF_CLOCK_LF_SRC_RC, \

.xtal_accuracy = NRF_CLOCK_LF_XTAL_ACCURACY_20_PPM}

Did you remember to apply this configuration in your bootloader project too? If so, can you try to debug the bootloader via Keil to see where the program hangs?

[quote userid="123126" url="~/f/nordic-q-a/96131/nrf51802-dfu-is-not-broadcasting"]I bulid it according to your experimental_ant_bootloader template,It also has a DFU service successful,However, Dfutarg broadcast cannot into.[/quote]

This bootloader is for ANT only, but it seems like you are planning to use BLE?

nrfutil settings generate --no-backup --family NRF51 --application app.hex --application-version 1 --bootloader-version 1 --bl-settings-version 1 settings.hex

Yes, except the --hw-version should be set to '51' and '52' if you use the default bootloader configuration.

Best regards,
