 Fri Apr 9 16:40:36 2021, NH, nnrpi1 Update
|
nnrpi1 is now back in S4 with a new SD card and new raspberry pi.
The freezing originally continued (it was the USB system failing) but was fixed with a change to /boot/cmdline.txt coherent_pool=4M
It seems the kernel update to fix one bug introduced another...

Wed Mar 31 15:46:09 2021, PJCS, HowTo : Synchronize the ASIC clocks.
|
To Synchronize the FEE64 ASIC clocks to rise at the same timestamp time use the System function Synchronise the ASIC clocks in the System
Wide Checks browser page.
The Server will read the current timestamp value and calculate, based on the number of FEEs and the access delay, a timestamp value sometime |
|
Wed Mar 31 15:40:42 2021, PJCS, Check Options files function added
|
There is a new operation available in the System Functions menu in the System Wide Checks page. ( The page needs to be reset once when the FEEs are powered
before this function will appear )
Check the Options files are all the same size |

Here is a document showing how and where to calibrate the LMK3200 devices that lock to the system clock and generate the clocks for the ADCs and the
FPGA internal logic. |

|
We had issues with all TTYs reading out on nnrpi1, I have moved them from an apparently faulty USB hub to a new one.
Trying to reboot the pi to detect the new USB ports and it didn't recover from boot
Trying to repair SD card but I get a lot of errors on my laptop, indications are the SD card is completely dead

08:07 Realised the correlation scalers hadn't been enabled again. Have enabled them now. R56_151
Looking through the merger messages from the nightshift we see bad timestamps in FEE 11. This FEE does not have any scalers going into it.

24:00 Joined in with TD to debug the dropout of AIDA05 - See https://elog.ph.ed.ac.uk/DESPEC/193
After both powercycles and telnet reboots we were still seeing 0 in the statistics but did note that the counter was > 0
The last check we did was a restart of the merger server. This solved the issue.
