Hi,

For MTCA specific configuration in mrfioc2, please take a look at the sample configuration here:
https://github.com/epics-modules/mrfioc2/blob/master/evrMrmApp/Db/evr-mtca-300.substitutions

in particular the substitutions for mrmevrout.db (from line 99 onwards). You see lines with FrontUnivOut[0,1], those should do the job for the Universal I/O slots in the front panel.

For the RTM outputs there is no example in the above file but I think you should be able to configure them using definitions like "RearUniv0" etc.

I am a little bit rusty on this so if there is somebody with recent practical experience, I would be happy if you could confirm that this is the case, or give the correct solution.

I hope this helps.

Best regards,

Timo

Hi Giampiero,


From the hardware point of view on the mTCA-EVR-300U the front panel 
Universal I/Os are configured/mapped through registers at offset 
0x440-0x447 (Front Panel Universal I/O Mapping Registers) and the RTM 
Universal I/Os are mapped through registers at offset 0x480-0x493 
(Transition Board Output Mapping Registers).


Unfortunately, I cannot help with configuring this through mrfioc2.


Thanks,
Jukka
