errors in nrfutil trying to generate DFU zip file

[Frank Hobelman]

Hi,

trying for a few days now to generate a DFU zip file from the blinky example on a PCA10056: 

nrfutil pkg generate --hw-version 52 --sd-req 0x9A --application-version 5 --application blinky_pca10056.hex --key-file private.key app_dfu_package.zip

errors keep on turning up:

first tried to install nrfutil with python 3.9 but I cannot install a version of nrfutil beyond 5.2.0 and pc-ble-driver-py 0.11.4

downgraded python to 2.7 has no effect:

Traceback (most recent call last):

size = max_address - min_address + 1

It would be great if somebody could help me get this up and running. 

Thanks

Hi,

python 3.9 but I cannot install a version of nrfutil beyond 5.2.0 and pc-ble-driver-py 0.11.4

Try using python 3.8 instead, and install it with 'pip3 install nrfutil' , for details, see these posts:

https://devzone.nordicsemi.com/f/nordic-q-a/68560/python-3-pip-and-nrfutil

--sd-req 0x9A

This looks to be an firmware ID for a S132 SoftDevice. You should double check that you are using the correct value here.

Hi Sigurd, 

Thanks for your response.

got it running with Py3.8.6, pc-ble-driver-py 0.15 and nrfutil 6.1.0

indeed i was not sure about the sd req.   im using the 1.4.0. / pca10056 

still no real progress to be honest.

This example does not use a Softdevice.Try the ble_app_blinky example instead(in folder examples\ble_peripheral\ble_app_blinky)

Hi Sigurd,

Thanks a lot. that made the difference!
