nrfutil generate dfu zip pkg error

[Kelper]

Hello,

I use nrfutil to generate the dfu .zip file, the error log is listed below. what is the reason?  the softdevice is s140.  thanks.

>>nrfutil pkg generate --hw-version 52 --application-version 1 --application nrf52840_xxaa.hex --sd-req 0x96 --key-file private.key AppDfuPkg.zip

Hello, 

Does the nrf52840_xxaa.hex contain any data outside of the application region? I haven't seen this error before, but seems to be related to hex to bin conversion. Could you share the .hex file so I can test it here?

Hello Vidar Berg,

The hex file attached. thanks!

Hello, 

The application FW starts at address 0 but should start at 0x22000 if you use s140 v.5.0.0-2 Alpha (memory layout). The first flash page is actaully reserved for the Master boot record (MBR), and is probably the reason for the error you see in nrfutil. Recommend that you use one of the BLE SDK as starting point, these will have the correct linker settings for use with the softdevice. 

For reference, here is the memory layout for the .hex file you provided:
