bootloader not working in NRF52810 SDK17

[Surya]

Hi,

I have a custom NRF52810 board in which i flashed modified code of low power ESB example and is working.

but when I flashed along with the bootloader, the application is not started. it is hanging in bootloader code.

I am using SDK 17.0.0.

application Linker settings 

DFU Linker settings

Hi Surya, 

What is the application after the bootloader jump for?

Do you generate a bootloader setting manually and merge it with the bootloader to trick the bootloader to accept the pre-flashed application?  See this tutorial getting-started-with-nordics-secure-dfu-bootloader. 

You have to download nRF-Command-Line-Tools to generate bootloader_setting and merge the image. 

I usually do like this:

mergehex -m softdevice.hex bootloader.hex -o merged_SD_bootloader.hex
nrfjprog --program merged_SD_bootloader.hex --chiperase

nrfutil settings generate --family NRF52810 --application app.hex --application-version 1 --bootloader-version 1 --bl-settings-version 1 settings.hex
mergehex -m hrs_app.hex settings.hex -o merged.hex
nrfjprog --program merged.hex --sectorerase -r

When you generate the bootloader setting, you should use --family NRF52810 for nRF52810.
