merged hex for production

[Martin Andersson]

Hi, I have NRF52 issues creating one hex file containing softdevice + app + bootlader + settings. The device does not boot up. But if I have flashed the softdevice first then flash my merged app + bootlader + settings everything works as it should. What do I do wrong?

It would be helpful if you gave the entire script you use to create the package and flash it. 

Here's what works for me:

#!/bin/bash
MODE="Debug"
NAME="dev"
VERSION="0.0.1"

while getopts "m:n:v:" option;
do
case "${option}"
in
m) MODE=${OPTARG};;
n) NAME=${OPTARG};;
v) VERSION=${OPTARG};;
esac
done

if [ -z "${MODE+x}" ]; 
  then echo "MODE is unset"; 
  else echo "MODE is set to '$MODE'"; 
fi

if [ -z "${NAME+x}" ]; 
  then echo "NAME is unset"; 
  else echo "NAME is set to '$NAME'"; 
fi

if [ -z "${VERSION+x}" ]; 
  then echo "VERSION is unset"; 
  else echo "VERSION is set to '$VERSION'"; 
fi

bootloader="ruuvitag_b_bootloader_3.0.1_s132_6.1.0_debug.hex"     
if [ -f $bootloader ]; then
   echo "Found bootloader."
else
   wget https://github.com/ruuvi/ruuvi.nrf5_sdk15_bootloader.c/releases/download/3.0.0/ruuvitag_b_bootloader_3.0.1_s132_6.1.0_debug.hex
fi

key="ruuvi_open_private.pem"     
if [ -f $key ]; then
   echo "Found key"
else
   wget https://github.com/ruuvi/ruuvi.nrf5_sdk15_bootloader.c/releases/download/3.0.0/ruuvi_open_private.pem
fi

Hi Otso, Thanks for the quick help, below is part of the original bat file:

nrfutil settings generate --family NRF52 --application nrf52832_qfaa.hex --application-version 47 --bootloader-version 1 --bl-settings-version 1 settings.hex
mergehex -m nrf52832_xxaa_s132.hex settings.hex -o bootloader_and_setting.hex
mergehex -m nrf52832_qfaa.hex bootloader_and_setting.hex -o app_bootloader_and_setting.hex
mergehex -m s132_nrf52_6.1.0_softdevice.hex app_bootloader_and_setting.hex -o softdevice_app_bootloader_and_setting.hex

nrfjprog --family NRF52 --program softdevice_app_bootloader_and_setting.hex --sectorerase

to 

nrfutil settings generate --family NRF52 --application nrf52832_qfaa.hex --application-version 47 --bootloader-version 1 --bl-settings-version 1 settings.hex
mergehex -m nrf52832_xxaa_s132.hex settings.hex -o bootloader_and_setting.hex
mergehex -m nrf52832_qfaa.hex bootloader_and_setting.hex -o app_bootloader_and_setting.hex
mergehex -m s132_nrf52_6.1.0_softdevice.hex app_bootloader_and_setting.hex -o softdevice_app_bootloader_and_setting.hex

nrfjprog --family nrf52 --eraseall
nrfjprog --family NRF52 --program softdevice_app_bootloader_and_setting.hex --sectorerase
nrfjprog --family nrf52 --reset

That did the trick! Thank you!

I wish I have put this question here earlier
