- my company already have firmware with nRF51 and SDK11
- recently, we made new Firmware
- watchdog timer feature
- so we modified application and bootloader
now, we want to make zip file for DFU. so end user can upgrade their firmware of device.
Question 1. how can I make a zip file for bootloader+application version
- in manual, it said, we cannot make BL+APP version zip. is it right?
Question 2. our old firmware had to make hex file with BL+SD+APP and "app_valid_setting_apply.hex" using mergehex.exe
as I know "app_valid_setting_apply.hex" is provided from Nordic and it prevents loading bootloader instead of Application, just after firmware programming.
If I had to make BL+APP version zip file, how can I make it with "app_valid_setting_apply" using nrfutil.exe
