Firmware vs SDK

[avizipi]

Looking at these two disscuasions I see that for the 2.53 and 2.51 have a recommended firmware which supports the sdk.
#11173
#10807

Also I noticed that intel support upward compatibility. Therefore, the same SDK will support firmware versions higher than the recommended firmware.

However I couldn't find a discussion or issue that will clarify this subject for other SDK versions. For example which firmware versions can be used while using the 2.48 SDK. while looking for a solution I found this page which pair firmware version with SDK version. https://dev.intelrealsense.com/docs/firmware-releases

Also I find this link:
https://dev.intelrealsense.com/docs/recommended-production-camera-configurations
This table recommend firmware version and SDK version but the list isn't full.

So my questions are, does Intel have a complete list of SDK versions and recommended versions? Does the SDKs have upward compatibility for firmware version? What does the right pipe line when it comes to working with the cameras? Where should I follow for the next recommended production configurations?

Thanks!

Hi @avizipi The RealSense SDK's Releases page lists details for each SDK version dating back to the beginning, with recommended firmware for each version.

https://github.com/IntelRealSense/librealsense/releases

The recommended firmware version for SDK 2.48.0 is 5.12.14.50

I strongly recommend using the recommended firmware for a particular SDK version instead of one that is newer or older than the recommended. Otherwise, a newer firmware may have a change that causes problems when used with an earlier SDK version.

The Recommended production camera configurations page is not intended to be a full list of firmware versions. It represents confirmed-stable firmwares that Intel recommends for use in projects where possible failures cannot be risked, such as commercial products or critical applications.

When a newer Recommended production camera configurations firmware is selected by Intel, it will be listed at the section that you linked to, so I recommend monitoring that link for updates.

If you would prefer to use more recent versions then an alternative to using production firmwares is to apply a 'one version back' rule, where you use an SDK and firmware version that is one version older than the latest one so that there is time for any problems to come to light before you commit to adopting them.
