All of H1 models are now running back at RCG3.2, some with their most recent code. Those with new code are waiting for a DAQ restart to resync the channel lists (scheduled for noon).

As of this morning there were several models which would not run: all ISI-HAM (h1isiham[2-6]) and h1susauxh34. These models got new code yesterday, but others did also and they had no reversion issues.

To verify that a clean rebuild of the new code against RCG3.2 fixes the problem, I used h1isiham6 on h1seih16 as a test case. To minimize the risk of Dolphin glitching the corner station if this did not work, h1seih16 was removed from the switch fabric prior to testing.

1. Remove h1seih16 from the Dolphin fabric and powered off the computer

2. Disconnected the Dolphin cable from the rear of h1seih16 and powered it up

3. Rebuilt/installed and restarted h1isiham6 code. At this point everything was running, SWWD was of course tripped due to the disconnected Dolphin cable.

4. Repeated step 1.

5. Plugged the Dolphin cable back into h1seih16, powered up computer, started models

Initially all was good, but after a few seconds the IOP Dolphin IPC for the SWWD went to no reception (64kHz error rate). I restarted the IOP several times and the problem appears to have resolved itself with no input from me.

I ran some diagnostics on h1susauxh34 during its crashes, then rebuilt that code against 3.2 and it is also now stable. Finally I rebuilt h1susauxe[x,y]  and h1pemmx.

ISI-HAM systems now have the Ramped-Watchdog code.
