nrf5util dfu package incorrect size

[gaminn]

I have nrfutil version 5.0.0. I run this command:

nrfutil pkg generate --hw-version 52 --sd-req 0xA8,0xAF,0xB7 --application-version 2 --application ./nrf5/Debug/nrf5.ihex --key-file priv.pem app_dfu_package.zip

It outputs: Zip created at app_dfu_package.zip

However, this .zip file has size of 1 kb, two files there: manifest.json and nrf5.ihex. Original hex file (./nrf5/Debug/nrf5.ihex) has almost 500 kb, so the size of app_dfu_package.zip is obviously incorrect.

What is wrong?

Hi,

Do you know what format the hex file has? I noticed the 'i' in front of hex which I haven't seen before and suspect the format is not recognized or supported by nrfutil.

Hi and thanks. I use VisualGDB and their toolchain which is GCC. I think it is standard hex format.

I see it. Renaming the file to nrf5.hex helps.
