Hi,

The mcuboot doesn't support the nRF5 SDK DFU protocol. Their roles are the same, but they are different protocols. The nRF5 SDK bootloader cannot support SMP DFU, and the mcuboot cannot support nRF5 SDK DFU.

Hi,

my question was more about the MCUBoot and not the nRF Util.

Does the MCUBoot support also the "old" nrf sdk DFU protocol. So that its behaving like the bootloader examples from the nrf sdk 17 or older?

Hi,

[quote user="MatthiasJ"]so it's possible to use the "old" nrf sdk DFU in the new nrfconnect MCUboot bootloader. That support the SMP DFU protocol and the nrf DFU?[/quote]

The current nRF Util can support only known Nordic kits/samples like thingy:53.

[quote user="MatthiasJ"]It's only not possible to test with the command line tool?[/quote]

No, nRF Command Line Tool cannot support updating DFU.

Hi,

From the team, the nRF Util currently only supports known Nordic kits/samples like thingy:53 etc for DFU updates via UART. We are working to support more use cases in the next release. Sorry for the inconvenience.

Ah, ok. Thanks I only used to know the pypi tool.

The first with USB connected to the dev board. Second one only serial adapter connected, while chip is in bootloader serial recovery.

Please upgrade to nrfutil v7.x.x and take a look at this One tool to rule them all: nRF Util becomes a unified command line utility .

Sorry I'm using nrfutil==6.1.7, the latest one. this does not have the device list. Do you mean onother tool?

Kind regards,

Could you run "nrfutil device list" and provide the return?

Thank you for answering. But maybe I missed some points for details. I tried to use the nrfutil dfu via serial, no USB.

I'm using a FTDI 3V3 UART converter.

Maybe you have also some comments.

Kind regards,

Matthias

Hi,

Try to add the following config into child_image/mcuboot.conf:

CONFIG_USB_DEVICE_VID=0x1915
CONFIG_USB_DEVICE_PID=0x5300
