Hi Bipin,

I'm glad it worked now. Yes, the modification you made to add {BANK_VALID_APP}; in should only be used if you want to flash the application manually without using the bootloader. When you update bootloader and softdevice the application will be erased, you should not use that modification.

Hi Hung,

"DFU_SmartBeacon_nrf52832AA_V1R1_B3_V0_0_4.hex" is a bootloader hex file. I have given name to it.

Actually my issue is resolve. Issue was with following line in bootloader_settings.c.

uint8_t m_boot_settings[CODE_PAGE_SIZE] attribute((at(BOOTLOADER_SETTINGS_ADDRESS))) attribute((used)) = {BANK_VALID_APP};

I have change it to

uint8_t m_boot_settings[CODE_PAGE_SIZE] attribute((at(BOOTLOADER_SETTINGS_ADDRESS))) attribute((used));

First line used only for merge file not for upgrade of bootloader.

Thanks Bipin Patel

Hi Bipin,

Have you made sure the DFU_SmartBeacon_nrf52832AA_V1R1_B3_V0_0_4.hex is actually the bootloader ? not your application ? Have you tried with our stock bootloader ?
