Programmer: Part of the HEX regions are out of the device memory size, but you can still proceed write operation.

[hannes]

We're using a nRF52DK and the Nordic-Programmer-App to flash our firmware on our custom boards. After upgrading to Programmer v2.3.3 I'm getting the Error-Message "Part of the HEX regions are out of the device memory size, but you can still proceed write operation." after adding the bootloaders HEX-file to the file memory layout. After flashing (App, Settings. Softdevice, Bootloader) the board stays in DFU-Mode.

Flashing the same HEX-files with the previous version of the programmer-App worked just fine. When I flash all the components with Segger Embedded Studio as "Additional Load Files" it's also working fine. So what has chenged in the new Programmer version, and how can I solve it?

Kind regards

Hi Amanda,

thanks. I already saw this answer but the solution there seems to be just to ignore the message, which is not possible in my case because after flashing the device stays in DFU-Mode without running the application...

Hi,

Do you also generate and flash the HEX file that contains the Bootloader Settings page? See the nrfutil documentation for instructions.

Yes of course. I'm flashing App, Softdevice, Bootloader and Bootloader Settings. With the old Programmer version it worked. It also still works using Segger Embedded Studios "Additional Load Files", but it doesn't work with the new Programmer app.

Mhm, sorry - I just recreated the bootloader_settings.hex and now it works. Don't know, maybe the file was damaged as we were using the same file since months....

Happy to know it works.
