[manhattan]

what does the mean of the statements the red line marked  on  above picture ? In my product ,i want to combine the softdevice,application and bootloader into one hex,and burn this all_in_one hex to nrf51822 chip with the tool jlink ,this method is ok?

Hi,

It means that the default bootloader in the SDK does not know that there is a valid application on the chip and will not branch to the application. You can however change this with one line of code such that you can flash the bootloader, SoftDevice and application at once using e.g. jlink. See this post for how.

Thank you ! The other question i got! In the site [https://devzone.nordicsemi.com/questi...] , i found in order to get the combination hex file of bootloader, SoftDevice and application , i need combined the "bootloader_settings.hex",so my problem is how can i create own " bootloader_settings.hex" file?
