bootloader_util_arm.c has been renamed to bootloader_util.c in SDK v8.1, which is not reflected in the SDK documentation. Using bootloader_util.c insted of the bootloader_util_arm.c file referred to in the documentation will result in correct behaviour.

Documentation error have been reported internally so that it may be fixed.

@zcmm: Please create a new question regarding the issue with Samsung S7 Edge and nRF Connect returning GATT_CONN_TERMINATE_LOCAL_HOST often.

Ok, then I will report the documentation error internally so that it may be fixed.

yes,it can jump,and work normally.but the 8.1.0 document let me add bootloader_util_arm.c file.

Yes, then I agree that it uses bootloader_util.c. So if you add the bootloader_util.c file, does your application jump to the bootloader?

The above screenshot is from SDK v8.0.0 and the ble_app_hrs example with DFU support for the PCA10028 board., which uses the bootloader_util_arm.c file. If you're using another SDK or board, then please let me know.

No, the examples\ble_peripheral\ble_app_hrs\pca10028\s110_with_dfu\arm5_no_packs\ble_app_hrs_s110_with_dfu_pca10028.uvprojx example includes bootloader_util_arm.c

if add bootloader_util_arm.c file,jumping to bootloader is fail.I see the HRM_DFU exmaple,it only add bootloader_util.c file.

No, you should only have to add bootloader_util_arm.c, dfu_app_handler.c and ble_dfu.c as instructed in the documentation found here. You also need to set up the DFU BLE services and propagate SoftDevice BLE events to the BLE DFU Service as shown in the documentation.

Your app shouldn't try to directly jump to the bootloader. The bootloader runs after a reset, before the application.

yes,but not jumping the bootloader,maybe the document is wrong.it should add bootloader_util.c file,rather than bootloader_util_arm.c file.

Firstly, you need to adjust the IROM1 size so that there is enough space for the bootloader since 0x18000 + 0x28000 = 0x40000 (128kB). The bootloader start adress is 0x3C000, so the correct size should be 0x3C000 - 0x18000 = 0x24000.
