ensure that Matt's latest xpm firmware fixes the xpm link-glitch storms
reproduce/fix TxLinkReset workaround
reproduce/fix xpmmini-to-lcls2timing workaround
reproduce/fix link-lock failure on timing system KCUs
reproduce/fix timing nodes assigning wrong timestamp to configure transition by 1 or 2 buckets
- matt thinks this is on the receiver side: some fifos that carry daq data separate from timing data. matt thinks perhaps we have to connect the resets to those fifos.
manufacture new boards
check/fix loopback fiber problem in production xpms in room 208
work on high-speed-digitizer timing robustness
check wave8 timing robustness

testing double offence.
rebooting a node with cameralink without the fiber connected and connect the fiber after

action	issue found	stat	remedy
rebooting cmp005 with timing fiber disconnected from xpm, then connect fiber when cmp is back on line	none	0/5	xpmpva does not see the opal until the daq is booted up. No ISSUES.

Brainstorming Session

Nov. 16, 23 with mona, dan, weaver, caf, claus, melchior, cpo

...

matt has an idea for bucket-jumps. could direct julian.

Results from Julian

has kcu1500 xpm (not xpmmini) transmitting to txi epixHR
with Dawood observed RxLinkUp never came up until they added debugging stuff
- saw something weird with the logic that reset the GTH on errors (state machine stayed in reset): this is fixed
- never saw any 929kHz frames counted (perhaps similar to xpmmini→lcls2timing issue we also observed?): not fixed
  - matt asks: are they stuck at zero? polarity wrong? two-byte sequences aligned on wrong byte?
also saw that the ConfigLclsTimingV2 button in devGui didn't work correctly (a missing register) and found a software bug which he has fixed for epixHR, but which may be broken elsewhere (fixed for epixHR)
- Julian will check camera link as well.

(from mtg on Nov. 27, 2023)

Julian:
- focus on the stuck frames in the epixHR system
- boards are in production (new AMC connector) just came back (4). Larry will work with Julian (with advice from Matt) to test the boards. One goes to BPM group, another to low-level-RF test stand
- will implement bucket-hopping fix (with advice from Matt)
Riccardo
- will test when bucket-hopping fix is available
- non-self-locking xpm ports
- longer term: add hsd/wave8 systems to test stand
cpo will try to reproduce the stuck-frames (which we "fix" with xpmmini→lcls2 workaround) with the tixel system that Christos Bakalis is using. Now scheduled for Dec. 12
