software pack compatibility confusion

[Vito]

I am working with nrf51422 chips version 2, so according to this table taken from the compatibility matrix v2.0, the last supported versions of SDK/SD/SDS I should refer to are:

I suspected compatibility issues in my projects, so I have erased the software packs manually and reinstalled the SDK 6.1.0 with nrf51_sdk_v6_1_0_b2ec2e6.msi (I couldn't find the .zip with the software pack installer)

What happens is that the software pack installer misses many software packs, and it offers me to download higher versions of everything. And other libraries has even different numbering. How should I choose the correct version of everything? Can I also use the following row (i.e. S110 v8.0.0?)

@Vito:

Could you try to follow this tutorial: https://devzone.nordicsemi.com/blogs/671/how-to-use-the-latest-keil-5-for-keil-4-projects-u/ and let me know if it worked for you ?

You can download the SDK v6.1.0 SDK zip file here.

Yes exactly, that's a bit of a boring job :) Unfortunately I have been tricked by the similar version numbers (SD S110 v7.1.0 goes with SDK v6.1.0...), and I have developed everything with the higher SDK. It was even working, unless some weird Hardfault showed up.

Thanks, unfortunately I have a stock of boards already equipped with XLR2 and I need to guarantee support for those.

By the way, SDK 6.1.0 seems compatible with XLR3, so I shouldn't have problems, right?
