Unable to Run Application hex after OTA

[saiteja]

Hi, i am using nrf52, sdk11 and S132v2.0.0. so i want to flash the hex file using OTA so that, i have create zip file using fallowing command.

**nrfutil dfu genpkg --application /nRF5_SDK_11.0.0_89a8197/examples/ble_peripheral/ble_app_hrs/hex/ble_app_hrs_s132_pca10040.hex  --application-version 0xffffffff --dev-revision 0xffff --dev-type 0xffff --sd-req 0x81 myAPp.zip**

then i had run the dfu_dual_bank_ble_s132_pca10040.hex(Advertising DfuTarget) on my PCA10040 then i connected through NRFToolbox. and able to flash generated zip file in the android application it is showing that OTA success but unable to RUN on the board what may be the issue

So the Application DFU completes successfully, but the device does not jump to the application and stays in bootloader mode? Does the device start the application if you power-cycle your device?

Hello,

Which SDK version are  you using? Are you performing the update on a nRF52 DK or a custom board? Which nrfutil version are you using and please post the command you used to generate the firmware image(i.e. .zip package).
