Tried this UserRst with blowoff/clearreadout, but doesn't help:

Also tried FpgaReload above and running the DAQ (including configure, since presumably the FEB lost its configuration) but still 100% deadtime.

Tried increasing the TriggerPulseWidth to 100us (was 0.092us?) but doesn't help with deadtime:

This TxOpCodeCount under Hsio→PgpMon[0] seems to only increase with L1Accepts.  We are getting far fewer of these than the L1Accept rate says we should.  Suggests we're dropping camera frames?

Possible breakthrough:  if I power cycle the camera and run without reconfiguring then L1Accepts show up in pgpreader at the correct rate.  Feels like our configuration is breaking the camera?  Compared the power-on defaults (https://www.slac.stanford.edu/exp/npa/manuals/opal1000man.pdf) to our config.  Don't see an obvious difference in UART settings except we have VR=1 (vertical remap) and OVL=1 (overlay frame counter and integration time on early pixel data)?.  Other differences (BL(black level), DPE (defect pixel correction) OFS (output offset)) feel like they don't matter.  Tried setting VR=0 and OVL=0 but it didn't help.  Set them back to 1.
