SDK11 : DFU fails with re-build application/bootloader example

[Gotta]

I am using a custom board with NRF51822-QFAC-R7 and Master Control panel on Android. The DFU is working with test images from SDK130. BL : examples/dfu/bootloader/hex/dfu_dual_bank_ble_s130_pca10028.hex SD: components/softdevice/s130/hex/s130_nrf51_2.0.0_softdevice.hex App: examples/ble_peripheral/ble_app_hrs/hex/ble_app_hrs_s130_with_dfu_pca10028.hex Other info: SDK11 nrfutil version: 0.5.1 Host environment: Ubuntu 14.04 Flashed the above images using nrfjprog on ubuntu.

Case(A):
A.1) I build an application image with noridc_sdk_11/examples/ble_peripheral/ble_app_hrs/pca10028/s130_with_dfu/armgcc with _MINOR ver as 0x05 and Adv name (no other changes) here after call as app_ver_5.hex

A.2) Created .zip file using below command: $ sudo nrfutil dfu genpkg --application _build/nrf51422_xxac_s130.bin --application-version 0xFFFFFFFF nrf51422_xxac_s130_hrs_ver5.zip

A.3) Copied to android mobile and updated using DFU option form the Andriod mobile app nRF Master Control Panel.

Result: New application came-up well and able to see change in advertisement name version.

Now, I repeated the above step A.1 (with _MINOR as 6 and some other adv name) A.2 and A.3, but this time observed some strange behavior

(1) It failed to boot the latest application image.

(2) Only Bootloader boots up with DfuTarg

Earliest response would be a great help.

Could you try one of the "default" .zip files in the SDK, and check if you see the same problem?

Could you upload your .zip file here (the one that is failing)?

Do you have an extra nRF51-DK or a nRF51-Dongle? If so, could you use the sniffer to track what is being transferred over the air? And upload the sniffer trace here?

The sniffer should be used with Wireshark, and it works best with version 1.10, not one of the newer versions.
