I ended up checking the manifest for each release tag and then creating my own table that maps git hash to release tag. So I'm good for now. Thanks.

Hi!

[quote user="denis"]So to summarize, the fw_version, fw_revision , fw_build numbers get turned into the git commit prefix. Correct?[/quote]

A Git commit number is used to generate these 3 variables.

The ll_subversion_number seem to be incrementing though.

[quote user="denis"]Is there any way to get a soft device version number from the git repo? And/or nRF Connect SDK version number?[/quote]

Not sure what you mean here, didn't you just do that by reading the manifest that is part of the git repo?

So to summarize, the fw_version, fw_revision , fw_build numbers get turned into the git commit prefix. Correct?

In the manifest.xml I see:

description: SoftDevice Controller
git_revision: 2d79a1c86a40b73cf674f90b22d3c480747282ba
ll_subversion_number: '0x206B'
ll_version_number: '0x0E'
timestamp: '2024-12-12T12:43:40Z'

Is there any way to get a soft device version number from the git repo? And/or nRF Connect SDK version number?

Hi!

The numbers looks correct. There is no major.minor.patch format to these fw_version, fw_revision , fw_build numbers. So you can't determine if the stack is newer or not by only comparing 2 sets with fw_revision,fw_revision, fw_build .

You need to look at the rev for the SDC, e.g. SDC for nRF53 NCS 2.9.0 here:

https://github.com/nrfconnect/sdk-nrfxlib/tree/v2.9.0/softdevice_controller/lib/nrf53/soft-float

For 2.9.0 it's 2d 79a1 c86a40b7 3cf674f90b22d3c480747282ba

hex 2d -> dec 45

hex A179 -> dec 41337

hex B7406AC8 -> dec 3074452168

[quote user=""]

fw_version =45 '-'

fw_revision =41337

fw_build =3074452168
