NRF51802 DFU is not broadcasting

[boysplay]

Hi,

    My nRF51802QFAA Module without an external 32khz oszillator.

    I use SDK 12.3.0 with keil,the ble_app_uart template works well the configs 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}

but the experimental_ant_bootloader and bootloader_secure/pca10028 template  can not wrok,I have experience with 52832 DFU and I tried many ways, but it didn't work.

my bootloader_secure/pca10028 configs for keil:

I bulid it according to your experimental_ant_bootloader  template,It also has a DFU service successful,However, Dfutarg broadcast cannot into.

And Is this script right with nRF51802QFAA?

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

mergehex --merge bootloader.hex settings.hex --output bl_temp.hex
mergehex --merge bl_temp.hex app.hex s130_nrf51_2.0.1_softdevice.hex --output BLE_Latest.hex

nrfutil pkg generate --hw-version 52 --sd-req 0x87 --application-version 1 --application app.hex  --key-file private.pem BLE_ota.zip

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?

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

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

Best regards,

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.

#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}

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?

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.

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:

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

The app runs good with the setting,I just share the info with other developers,thanks a lot.
