Unfortunately, we are going to implement it, but don't have an accurate estimate of when that will be. That said, this redesign has made it easier to add custom transport layers compared to the legacy bootloader in case you would be interested in creating your own.

Thanks Vidar! Any timeline on getting serial DFU supported in SDK12?

Hi,

The DFU was redesigned in SDK 12.0.0, hence two different versions of nrfutil. From the readme:

Versions

There are 2 different and incompatible DFU package formats:

legacy: used a simple structure and no security

modern: uses Google's protocol buffers for serialization and can be
cryptographically signed

The DFU package format transitioned from legacy to modern in SDK 12.0. Depending on the SDK version that you are using you will need to select a
release of this tool compatible with
it:

Version 0.5.2 generates legacy firmware packages compatible with nRF SDK 11.0 and older

Versions 1.5.0 and later generate modern firmware packages compatible
with nRF SDK 12.0 and newer
