Re: Problems using Universal I/O

[Han Lee via Tech-talk <tech-talk at aps.anl.gov>]

Hi Timo,

Oh, it is great news for them, good to hear about them. When I worked there, we didn't have a RTM unit.

I remembered we developed the ess customized MTCA EVM and EVR substitutions also, but I cannot find them anymore, except my personal copy.

After my leaving, ESS changed e3 architecture a lot, so I cannot follow their changes, and how they want to use all db, and substitutions files.

You may suggest ESS engineers, especially those who know mrfioc2 and maybe e3-mrfioc2, and push their changes and improvements to the community, which I always did regularly.

I don't think we can do this every time, I think, RTM units are available now, and ESS designed and has the working version. It is better to share them with the community from my view.

Thanks, Timo, always!

@Giampiero, if you work with ESS as in-kind projects, sometimes, it is easy to talk to them directly, since MTCA MRF products were introduced by ESS. I think I contributed to them when I was there.

Best,

Han

Hi Han,

 

Well…both Jerzy and Javier are absent at the moment (parental leave) so asking them may not work. However, the file I linked is already in the community repo. Did you also develop files for the RTM outputs? If yes, I try to find it tomorrow and make a pull request.

Hi Timo,

 

This file was developed by me and Javier, and I think ESS has the corresponding db or substitutions files locally. If so, could you, Jerzy or Javier, push ESS local files to the community repository?

 

Best,

Han

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
