During a couple of weeks testing of a Zgemma H7C. I have seen some crashes. Sometimes only in /var/log/messages and sometimes the box stop responding. I haven't had time to investigate these, but now I starting to write about it. Because now I have one situation I can recreate. After a factory reset I select to auto restore backup. The box will stop responding on OpenPLi logo and the following can be found in messages file:

I notice a CI function. It is a CAM in the box. I remove it and did factory reset and autorestore - OK. Plug in the CAM and factory reset and autorestore - OK.

So now it seems the problem disappear.

This looks like a driver crash in the CI module handling code. Nexus is the name of the Broadcom SDK.


Currently in use: VU+Duo 4K (2xFBC S2), Amiko Viper T2C (T2), SAB Alpha Triple HD (S2+T2), Zgemma H3.T2C (T/C), Zgemma H6 (fallback), VU+Zero (fallback)

I shutdown the box, power off and reflash with USB... same crash again. After autorestore, increasing digit in the front display and now show "-00-".

How can reflash fix a bug in the drivers?


* Wavefrontier T90 with 28E/23E/19E/13E/9E/4.8E/0.8W/5W via SCR switches 2 x 2 x 6 user bands
* Ziggo digital cable TV (FTA)
I don't read PM -> if you have something to ask or to report, do it in the forum so others can benefit. I don't take freelance jobs.
Ik lees geen PM -> als je iets te vragen of te melden hebt, doe het op het forum, zodat anderen er ook wat aan hebben.

No, but it was to get the fault again. Since after one reset/autorestore, it doesn't happend at second reset/autorestore, or third. However after a reflash it happen.

Here comes two other exceptions. I think one of these came while playback a recording over samba share. The playback went ok, the box didn't stop. Maybe out of memory?

Two identical crashes in two different processes. I wonder if this box doesn't have some hardware issue?

 

Or something running that eats up all memory?

I have installed a H7 at my parents home and its has many problem, they often need to reboot it. So I replace it with with another brand and model and now everything is running fine. It was used only in DVB-C.

This is physical memory (not virtual memory) being all eaten up. Which is very strange to happen, you can't get this to happen from allocating memory from a user space process.

 

So the drivers are to blame (once again).

 

I am never getting these errors, what kind of weird things are you (TS) doing on your receiver?

I have doing a lot of terrest channel search (I think, I am actually unsure about which settings I had while this appeared). It seems like it mess things up. For example press the All button sometimes result in less channel show in the list. The day after these memory messages I played the same movie again and no messages. I have planned to test more, playback and watch the memory - we will see when I get time for it. I will not use any old strange settings. The box will either be terrest or fallbacktuner.

I have played some more movies the same way in this box and no strange messages in the message file.

PS. One thing that might be little special is that the fileshare is read-only. I don't know if that can be a problem or not.

Are you playing many media files?

I have played 2½ recordings (via samba share). So answer is: No

Now this machine have 7.1 and no old backup of settings. However now I am testing what I really should test on this machine, terrest and recordings (doesn't go good, but another story). I might test fallback and fileshare playing again later on.

After the exceptions I have written about in this thread, I haven't seen any more - except this:

Blue dot spinning around in top left corner - what is it?
The box not responding!

It means the UI thread is busy. It may come from a plugin not properly programmed and doing lots of work in the foreground, but it may also come from a driver crash (check dmesg).

I'm testing a Zgemma H7C for receiving of terrestrial signals (twin tuner). For the wanted channels a CAM (CI+) is needed together with the smartcard.

I have these settings in OpenPLi 7.1:
config.recording.always_ecm=true
config.recording.never_decrypt=true

1) I watch a channel and start a recording (on that channel). If I now change channel, it will be black picture! I guess the CAM is occupied, but it shouldn't. What do I do wrong (missing a setting)?

2) I have recorded a program, via timer. Box was not in use during recording. In the file list I select the recording and start offline decoding. The live channel is still playing (in the little window) during this, should it? I thought the offline decoding would take exclusive ownership of the CAM.

3) I try to watch the origin recording (scrambled). Time jumping in steps and after a while picture appear, but still time is jumping. I'm actually not sure what it is I'm seing. Stop play. Now start play the decoded file, it is possible. Now I tested to play the scrambled again. I don't remember exactly what I did (play), at exit of the file list view I got the spinning blue dot in top left corner:

Thanks. Took some time, but find it below CI settings. So now I also have: config.ci.0.canDescrambleMultipleServices=no

...but it didn't help. Still black picture if I change channel, if recording started.

If I start recording a free channel. I can watch other channels, both free and scrambled.

If I start recording a scrambled channel. I can watch free channels, but not scrambled channels (except the one being recorded).

Dimitrij: Do you also have a H7 box?
