Hi Michael, Alexis,

We have been working with the RTM card from MRF for the last year and with the new versions of the mtca EVR card (mTCA-EVR-300U and mTCA-EVR-300RF).
We have found that RTM is working as expected with both of them, but you need an EVR FW that is at least **0F0207** and a corresponding MMC firmware. 
You can check with us directly or reach out to Jukka for the correct/latest versions. 
We are still testing the RTM functionality with UNIV-IO modules with Delay functionality.

My colleague (Žan Matic Pratnemer) has published (in the last day or so) some pull requests to the official mrfioc2 github repository that should help others with the new HW.

Please take a look and provide comments/guidance on pull requests.

Best regard,

Žiga
