Details

• Session begins at 13:15
• Submitting CoherentModeTestsCal SB in mode c1500x4096 at 13:25
  • Scan ran OK except that I had apparently turned the cal off in the configuration at some point. Running again to double check that it looks OK when it's actually on.
  • Second scan aborted due to faults on Bank A
    • Faults in roach_state, master_slave_sel, scape_p1, scale_p0, nchan, dest_port, dest_ip
    • Tried manually tweaking scale_p0 and scale_p1 in CLEO. Still in fault.
    • Tried to conform params and prepare using CLEO. Still in fault.
    • Can't communicate with ROACH2 using katcp in python. Luke is coming up to investigate.
    • Did a manual progdev using katcp and that worked. Was then able to read back from arm register.
  • Tried to submit a scan again. Above faults cleared but then scan aborted due to HPC program taking too long to be ready. Tried again and got the same abort.
  • Cycling manager off/on and trying again.
    • Got register faults again while activating.
  • Seems like ROACH is alive but not programmed??
  • Another manual progdev worked and cleared the register faults again.
    • Tried an off/on and it faulted again.
  • Luke is going to look into this more.
• Putting release BOF files back into vegas.conf and restarting VEGAS.
• Taking verification scans at 14:03
• Looks OK. Session ends at 14:16

Conclusions

• Holding off on any further testing until we know what is causing these faults.
