It's supposed to be nrf5sdk-tools, not nrfsdk-tools.

Hi Vidar
Thank you for the information however I am struggling.

I have
nrfutil 7.5.0 (063f665 2023-05-11)
commit-hash: 063f665c8ef5e4d46167077b52d39cf4e66ca24f
commit-date: 2023-05-11
host: x86_64-pc-windows-msvc
build-timestamp: 2023-05-11T07:46:36.6366955Z
classification: nrf-external

Running as per your suggestion I have ..

E:\Temp\NordicDfuTest>nrfutil nrfsdk-tools pkg generate --application app.hex app_dfu_package.zip
Error: nrfutil command `nrfsdk-tools` not found. See `nrfutil list` for full list of installed commands, `nrfutil search` for installable commands, and `nrfutil install` for installation of new commands.

Caused by:
Subcommand nrfutil-nrfsdk-tools.exe not found

And the following:-

E:\Temp\NordicDfuTest>nrfutil list
Command Version Description
nrf5sdk-tools 1.0.1 nRF5 SDK tools that were available in nRF Util 6
dfu
keys
pkg
settings
zigbee

Found 1 installed command(s)

Goal: I have created an APP.hex built using the example application "usbd_ble_uart_freertos" and I want to create a dfu package that can be deployed to customers.

Hi Mahendra,

No problem. Yes, you should use nRF Util to generate the DFU distribution packets, see 'Generating DFU packages' for what commands to use. I also recommend taking a look at the getting started guide here: Getting started with Nordic's Secure DFU bootloader, a step by step guide

Note: For secure DFU commands in nrfutil version 7.0 or higher, 'nrf5sdk-tools' must be specified as the initial command argument.

E.g.,

nrfutil <= 6.x.x

nrfutil pkg generate --application app.hex app_dfu_package.zip

nrfutil >= v.7.0

nrfutil nrf5sdk-tools pkg generate --application app.hex app_dfu_package.zip

Kind regards,

Vidar

Hi Vidar
Thank you for your feedback.
I was able to get to that understanding.
What I am struggling with is
(1) taking my APP.hex and SD.hex and creating a package so that I can feed it into the upgrade process.
(2) what utility do I use to upgrade that implements that process.

I bet that information is somewhere but I struggling to locate it.
I know nrfutil is involved but not how.

Kind regards
Mahendra

Hi Mahendra,

It is possible to perform DFU over USB within the bootloader if you use the /examples/dfu/secure_bootloader/pca10056_usb example (Secure DFU Bootloader over Serial Link (UART/USB). DFU can be performed via the bootloader without involvement from the application. The only requirement is to have a mechanism in place for resetting the device into bootloader DFU mode. This can be achieved by having the application set the 'DFU enter' flag in the GPREGRET register followed by a soft reset, or by assigning a button that triggers the bootloader to enter DFU mode upon startup.

There are several methods to signal the bootloader to enter DFU mode following a reset. You can find an overview of the different available methods by searching for NRF_BL_DFU_ENTER_METHOD_ in the bootloader's sdk_config.

Best regards,

Vidar

The DFU is a separate firmware that is flashed at the end of the Program Flash. No extra work in application firmware except if you want it to be able to boot into DFU directly or use Nordic DFU ble service.

Send me PM for paid services.

Magic. Thank you for the suggestion. However quick glance there is no further documentation regarding how to integrate my usdb_ble_uart_freertos application on top of that.

Or is it the case that the DFU application will be loaded at the top of the flash and so there is nothing extra I need to add to my application?

Offer still on table for paid help :-)

look in the examples/dfu of your SDK folder
