Hi.

In step 4:
nrfutil settings generate --family NRF52 --application nrf52840_app.hex --application-version 3 --bootloader-version 2 --bl-settings-version 1 settings_52840.hex

Try:

step4:
nrfutil settings generate --family NRF52840 --application nrf52840_app.hex --application-version 3 --bootloader-version 2 --bl-settings-version 1 settings_52840.hex

Hi.

Could you please provide only the bootloader settings .hex file?

Hi.

Could you provide log from test 3?

I do not have a good solution to this problem now. so if there is a better way to merge these hex, can you tell me?

Hi:

this is test 2 log. I haven't changed anything bootloader or application.

Hi.

If test 2 fails then there is something wrong with the bootloader.

Have you edited anything in the bootloader? If not, then the address jump in the bootloader is most likely wrong.

Hi.

Test 1: Softdevice and Application merge,application can be start.

Test 2: Softdevice,Application and bootloader,application cann't start.

Test 3: Softdevice ,Application,bootloader and settings.cann't start.

The result is the same as nRFgo and mergehex.exe.

AndreasF — Thu, 01 Nov 2018 08:08:11 GMT

Hi.

Could you try this:

1. Flash your SoftDevice and Application without using mergehex.exe, does the application start?

2. Flash your SoftDevice, Application, and bootloader without using mergehex.exe, does the application start?

3. Flash your SoftDevice, Application, bootloader , and bootloader-settings-page without using mergehex.exe, does the application start?

I use the version of s140_nrf52_6.1.0_softdevice.hex.Application start address.I haven't changed anything.

RE: nrf52840 app and bootloader merge. the program did not jump to application execution.

AndreasF — Wed, 31 Oct 2018 08:04:00 GMT

Hi.

You have to make sure that the SoftDevice version matches with the application start address.

If they do not match, the SoftDevice will not know where to start the application from, and it will not start.
