Hi Andri,

it would be great if you could confirm if your trying to update the dongle with an application built with Zephyr or if its an application built with the nRF5 SDK. If it is a Zephyr application then you will have to make sure it is compatible with the interrupt forwarding scheme of the MBR, as stated by PaKa.

just to make sure, if you plan to use Zephyr then you should not have the Softdevice programmed, seems the suggestion from Bjørn used this.

The Dongle will always have the MBR from the Softdevice in the first block (unless you use an external SWD programmer for programming) so your Zephyr application needs to work despite this, that means work with the MBR interrupt forwarding scheme. You may use VTOR to change the location of the interrupt table as an option.

Hi Bjørn,

It's understandable given the fellesferie.

You wouldn't happen to know how I can configure the FLASH start address in Zephyr? They have quite a complicated build system. Editing the linker script does not seem to be a straight-forward task.

HI Andrii,

I sincerely apologize for the late reply.

You should be able to generate an application firmware image that uses the S140 v6.0.0 using the following command

nrfutil pkg generate --application ble_app_blinky_pca10059_s140.hex --application-version 5 --hw-version 52 --sd-req 0xA9 ble_app_blinky.zip

Note: You need to set the FLASH length so that ORIGIN+ LENGTH < 0xE0000 (start address of the bootloader)

I found out that the nRF Connect programmer will work if I edit the GCC linker script. Replace:

MEMORY
{
  FLASH (rx) : ORIGIN = 0x0, LENGTH = 0x100000
  RAM (rwx) :  ORIGIN = 0x20000000, LENGTH = 0x40000
}

with

MEMORY
{
  FLASH (rx) : ORIGIN = 0x1000, LENGTH = 0xff000
  RAM (rwx) :  ORIGIN = 0x20000008, LENGTH = 0x3fff8
}

It does not help with nrfutil, so I'm still missing a way to do it on the command line.
