Firmware Versions Details
Version C11 and Earlier
These versions had random channel timing offsets of 4 ns which changed from run to run.
Version C12
Summary
The 4ns offsets appear to be gone. There is evidence of corruption in a single event in a single channel at low probability very early (within the first few events) in the beginning of a run. Following this all data seems okay.
Evidence
- 4ns shifts are gone https://logbooks.jlab.org/entry/3743512
- Pulses show up later in the run: https://logbooks.jlab.org/entry/3756335
Version C13
Summary
Does not appear to show any issues.
Evidence
- No errors on the updated boards https://logbooks.jlab.org/entry/3756284
- Emulating raw mode shows no errors https://logbooks.jlab.org/entry/3756356
- No errors on the updated boards https://logbooks.jlab.org/entry/3756772
- test runs 71243-71248: no crashes in decoding https://logbooks.jlab.org/entry/3756734
