Hello,
We have a small experiment with MIDAS based DAQ.

Dear all,
in 13 Feb 2020 to 21 Feb 2020 we had a talk about how I try to create MIDAS events directly on a FPGA and

Any error messages printed by the frontend? any error message in midas.log? core dumps? crashes?

I finally got the dummy program working. There were several issues:
- event_buffer_size was defined as 10000 * 32 MB = 320 GB, exceeding the RAM of the computer

The problem has been fixed on commit 825935dc on Oct. 2021 and runs fine since then at PSI. If TRIUMF people

I just came back to this and started to use the dummy frontend.
Unfortunately, I have a problem during run cycles:
