Flashing bootloader and application via J-Link

[Nikita]

Hello. I want to make flashing of devices for production faster. So I want to write application together with bootloader via J-Link simultaneously and not via OTA DFU. I'm using S110 v6 and dual bank BLE DFU from SDK 5.1 example. I know that after flashing bootloader and application I just need to compute CRC16 of the DFU bank 0 and write this value to the bootloader settings in the flash, but maybe someone already has a solution to this problem?

It seems you didn't initialize m_boot_settings in your bootloader_util_arm.c: uint8_t m_boot_settings[CODE_PAGE_SIZE] attribute((at(BOOTLOADER_SETTINGS_ADDRESS))) attribute((used)); But what you need is: uint8_t m_boot_settings[CODE_PAGE_SIZE] attribute((at(BOOTLOADER_SETTINGS_ADDRESS))) attribute((used)) = {BANK_VALID_APP};

If I add BLE_VALID_APP I will get ERROR: The file specified is not a valid hex file, has data outside valid areas ERROR: or does not have data in valid areas.
