I had not heard of a mTCA-EVRTM-300 before, though as I recall there was
a previous IFB breakout module for early mTCA-EVR-300 cards (there are
two variants, which both identify as mTCA-EVRTM-300).

Are "TBOutput" and "RearUniv" the names which appear in the MRF
documentation you have?

Could you also give the register offsets?

see also the output register ranges currently understood by mrfioc2:

Probably not.  The mrfioc2 driver may need to be updated with the
mapping between physical and logical outputs.


The input/output configuration for the mTCA-EVM-300.  This does list 16 rear output
ports for the older IFB breakout.  Maybe your card is being mis-identfied?

The software mapping of output register to symbolic name:

Note that there are some special cases here, including with the mTCA-EVR-300
for the TCLKA and TCLKB GTX registers.
