Well and what do you expect us to suggest? You are comparing some firmwares which we have no clue about, E.g. if ZIP is bigger then I suppose that input HEX file is much bigger;) Have you used genpkg utility to prepare your won ZIP files from example project's HEX files and compare how that works vs. ZIP file generated by Nordic and delivered with SDK or other method?

Sorry don't take it wrong but the description sounds to me like "I've constructed space shuttle and now it doesn't work, what should I do?" The only suggestion I would give you is "Disassemble it to pieces and start slowly step by step and verify that all works after each little step" aka "Go back to some working code, verify that it works as it should and then do small customizations and verify that none of these small steps break the functionality".

hey Thank you for quick reply, i have tried with DEBUG, there is no errors and hex is able to flash on the board and if i power reset the board it is going to bootloader mode but the flashed application is not running on the board. i have tried with ZIP file present in the example SDK also still i am getting same issue.

You should run target in debug mode so you can see if the problem happens before upload is finished or after it (when new app should boot). And all that only for application which is 100% working when flashed over JTAG/SWD! Without that never go to things like OTA bootloading or other auxiliary features...

As endnode said, you should debug your program and see what happens in your bootloader after uploading your application.

yes its

FLASH (rx) : ORIGIN = 0x1c000, LENGTH = 0x64000 RAM (rwx) : ORIGIN = 0x20002080, LENGTH = 0xdf80

Also make sure you did set the correct start address for your application (0x1C000 for sd132 v2.0.0)

Then you need to go back to basics and debug:)

Hi,

You will need to create a ZIP package from your hex application file. You can use nrfutil to do such zip packages. For example with s132v2.0.0 softdevice:

nrfutil.exe dfu genpkg --application app.hex --application-version 0xFF --dev-revision 0xFF --dev-type 0xFFFF --sd-req 0x81 dfu_app.zip
