It is a very old question, but I will reply as it may be useful.

#elif defined ( __ICCARM__ )

const uint8_t m_boot_settings[CODE_PAGE_SIZE] @ BOOTLOADER_SETTINGS_ADDRESS = {BANK_VALID_APP};                                                    
__root    const uint32_t m_uicr_bootloader_start_address @ NRF_UICR_BOOT_START_ADDRESS = BOOTLOADER_REGION_START;                   

#endif

This seems to be solved.

thanks.

Can you readout the bootloader settings page after you have flashed the bootloader, softdevice and application using the nrfjprog command below?

nrfjprog -f nr52 --memrd 0x7F000 --n 64

Please post the output in a comment here.

Thanks! It was compiled . But the app doesn`t starts . I flashed the softdevice after it the bootloader and the app. I am flashing using the nrfjprog. Maybe there is another way?

Can you try to remove the __no_init attribute, i.e.

uint8_t m_boot_settings[CODE_PAGE_SIZE] @ BOOTLOADER_SETTINGS_ADDRESS = {BANK_VALID_APP};

I cannot compile this change : Error[Pa034]: an initialized variable can not have the __no_init attribute

Let me know if you run into any issues with setting the flag. If the answer above solved the issue, then I would appreciate if you could mark the answer as correct by clicking the checkmark in the circle to the left of the answer.

Hi Anna,

if you're using IAR then you have to change the m_boot_settings variable that is within the IAR specific statement, indicated by the #elif defined ( ICCARM ) ... #endif statement and not the gcc specific statement, i.e.

#elif defined ( __ICCARM__ )

__no_init uint8_t m_boot_settings[CODE_PAGE_SIZE] @ BOOTLOADER_SETTINGS_ADDRESS = {BANK_VALID_APP};                                                    
__root    const uint32_t m_uicr_bootloader_start_address @ NRF_UICR_BOOT_START_ADDRESS = BOOTLOADER_REGION_START;                   

#endif

Best regards

Bjørn
