Fix RFM channels |
|
|
[Paco, Yuta]
We tried fixing the issue of LSC_TRY and LSC_TRX channels not working. We first did some investigation, and just like previously reported by Chris, narrowed down the issue to the RFM channels coming from c1iscex/c1iscey.
First attempt : FAIL
In our first attempt, we
- Tripped ETMX/ETMY watchdogs, ssh to c1iscex/c1iscey and restart the rtcds models.
- Since the last step didn't fix things, we decided to do the same thing on c1lsc, c1sus, c1ioo.
- After hard rebooting c1ioo and c1lsc (because they died during the stopping of rtcds models), and not experiencing any timing issues (nice), we still don't fix the issue.
Second attempt: Success
A second attempt just followed Koji's previous fix explained here. Basic difference with our first attempt was a hard reboot of c1iscex/c1iscey in addition to the rtcds model restarting. RFM channels were then clear of errors and we recovered our IR transmission channels in the LSC model. |
