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?

    Does the bootloader working properly? If the bootloader working properly and updates your app just fine but app doesn't start then it may be that UICR are not programmed. If you write your UICR separately from bootloader hex then you need to add additional nrfjprog write to the UICR.
