Mapping old kconfig symbols to new versions of the SDK

[finkbr]

Hi,

I have a working set of code that we are going to move to the latest version of the SDK.  Currently we are using v2.3.0.  I am trying to move to another version (2.6.0). I know there will be things that will cause problems but what i cant figure out is how to find new kconfig items such as CONFIG_COUNTER_TIMER1.  this works in 2.3.0 but doesn't in 2.6.0 when defined in the prj.conf.  Is there someplace I can look to see what config items are removed and what they now should be for each new version?  These types of things are very difficult to find and I am new o this set of code so im having a difficult time figuring out how to map the old defines to new defines if they even exist.  Suggestions?

Thanks in advance

Brian

Hi Brian,

My usual approach is to search through the release and migration notes to see if there is any mention of the change. Unfortunately, the removal of the CONFIG_COUNTER_TIMER1 symbol does not appear to be mentioned anywhere.

These symbols were removed by this commit: https://github.com/nrfconnect/sdk-zephyr/commit/656b0e642698be47b44931ea1b81ccf60f4b34cb.  The fix is to remove the CONFIG_COUNTER_TIMER1 symbol from your prj.conf file and make sure the timer1 node is set to 'status = okay' in your devicetree.

Best regards,

Vidar

Is there a central place for release and migration notes?  This makes it REALLY hard to upgrade to a new version of the SDK.  :-/

You can search across the SDK tree as shown in the screenshot to find keywords in the Zephyr and nRF Connect SDK release/migration notes. You can also read through the release/migration notes here : https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/releases_and_maturity/release_notes.html and here: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/releases/index.html#release-notes

ok thanks for the information.  Looks like moving to a new version of the sdk is just a painful process.
