Warning While creating a DFU package

[sridharnaidu]

Hi,

While creating a DFU package using nrfutil with dfu genpkg command, it is showing following warning. 

===============================================================|
|You are not providing a signature key, which means the DFU |
|files will not be signed, and are vulnerable to tampering. |
|This is only compatible with a signature-less bootloader and is|
|not suitable for production environments. |
|===============================================================|

What is the possibility for this error?. if i have to sign the image , how to do it?

Thanks,

Sridhar.

Hi.

You have to generate a key file that you use to sign the DFU package with.

Are you working on an example in the SDK? Which example and which SDK are you using?

Best regards,

Andreas
