| T42 | <edp_17> Mal: good morning. I tried those but didn't make any difference. | 05:21 |
|---|---|---|
| T42 | <edp_17> It looks already zomed in when the camera app starts because the image is big. Manually I can zoom in/out and all other settings in the app work. The app doesn't crash or freeze. Strange. | 05:23 |

| T42 | <edp_17> mal: In init.rc the led paths doen't look correct for that device: https://paste.ubuntu.com/p/spmpd3vccK/ | 09:07 |
| T42 | <birdzhang> you can manually trigger leds to figure out which is the correct one | 09:21 |
| T42 | <edp_17> I already have tested that with echo. Like: echo "255" > /sys/class/leds/led_b/brightness | 09:34 |
| T42 | <edp_17> That worked. | 09:34 |
| T42 | <birdzhang> on vince, it has fake rgb leds, only red is working | 09:48 |
| T42 | <birdzhang> 😅 | 09:48 |
| T42 | <edp_17> Well, I've amended those lines on device in init.rc but after reboot leds are still not working. https://paste.ubuntu.com/p/5cmbqQ94Q9/ | 09:50 |
| mal | group should be input, not system | 11:16 |
| mal | for sailfish use, in android it's system group | 11:17 |
| T42 | <edp_17> And what about the others, where the group is system? https://paste.ubuntu.com/p/qWwKDPW2Rr/ | 11:19 |
| T42 | <edp_17> /sys/module/sco/* and /sys/kernel/ipv4/* Are they correct? | 11:20 |
| T42 | <edp_17> I've amended all /sys/class/leds/ entries to have chown system input but still no LEDs. | 11:36 |
| mal | usually just things we use directly from sfos might need permissions changes | 11:46 |
| T42 | <elros34> @edp_17 did you confirm that changing permission in init.rc actually worked? chmod a+rw your led paths then restart mce and you will see what happen. | 12:53 |
| T42 | <edp_17> @elros34 : I confirm changing permission in init.rc didn't solve the issue. (I rebooted the device rather than restart mce.) | 13:09 |
| T42 | <edp_17> Here is how the leds permission look like This is example of red: https://paste.ubuntu.com/p/YtpFj3YbXB/ | 13:10 |
| T42 | <edp_17> This is how I amended init.rc on device: https://paste.ubuntu.com/p/rK73tnVwHk/ | 13:12 |
| T42 | <elros34> it's better to chmod and restart mce to rule out permission issue, especially that this second report about mce/led issue which suggest some other source for this | 13:17 |
| T42 | <edp_17> Okay, let me try that. | 13:19 |
| T42 | <edp_17> @elros34 : I set this and restarted mce but didn't help: https://paste.ubuntu.com/p/pVPG6ZpYkg/ | 13:23 |
| T42 | <edp_17> Also tried to set chmod system:system on blink and brightness and restart mce, didn't help: https://paste.ubuntu.com/p/TPgHbGwjfH/ | 13:27 |
| mal | why system:system? | 13:36 |
| T42 | <edp_17> That was originally in init.rc | 13:37 |
| mal | where is your config repo on github? | 13:37 |
| T42 | <edp_17> mal: https://github.com/edp17/droid-config-treltexx | 13:38 |
| mal | try setting 644 system:input for those delay* ones also | 13:39 |
| mal | 664 | 13:40 |
| T42 | <elros34> you should be do chown for all files or what mal just said to rule out unlike pemission issue and focu on debuggin mce itself | 13:40 |
| T42 | <edp_17> Should I change blink and brightness to system:input ? | 13:40 |
| mal | yes | 13:40 |
| T42 | <edp_17> Okay. | 13:41 |
| mal | hmm, or do those actually affect anything | 13:41 |
| mal | wait, why is that backend in config RGB, use vanilla for that | 13:44 |
| T42 | <edp_17> It was always RGB for this device. | 13:45 |
| mal | well just try | 13:47 |
| T42 | <edp_17> still no luck: https://paste.ubuntu.com/p/kstX9zVd53/ | 13:55 |
| T42 | <edp_17> Should I just chmod a+rw all those files? | 13:56 |
| mal | anything in journal from mce | 13:56 |
| mal | even 666 for those paths doesn't help? | 13:56 |
| T42 | <edp_17> Okay, so those files chown to system:input and chmod 666. Still no leds. Journal: https://paste.ubuntu.com/p/GQxfzG3yPX/ | 14:07 |
| mal | try checking debug output from mce or even strace to see if it even tries to do anything with leds | 14:24 |
| T42 | <edp_17> I tried to strace mce but got a full screen of running text constantly. In there I didn't even realize when tried the leds in csd. | 14:31 |
| T42 | <elros34> with "strace -f -e file"? | 14:37 |
| T42 | <edp_17> Like this? https://paste.ubuntu.com/p/KfWnfqVwsp/ | 14:42 |
| T42 | <elros34> but mce is system process not user one, see systemctl cat mce | 14:43 |
| T42 | <elros34> ah you use sudo, sorry | 14:44 |
| T42 | <edp_17> Yes. And mce service was stopped. | 14:44 |
| T42 | <elros34> did you start leds via charging or something when gathering this log? | 14:45 |
| T42 | <edp_17> I started csd from command line and went into the test LED. | 14:46 |
| T42 | <elros34> looks like mce led plugin is not used | 14:47 |
| T42 | <edp_17> These are the installed *mce* packages: https://paste.ubuntu.com/p/txcR2PBWVn/ | 14:48 |
| T42 | <edp_17> Or is that led plugin embedded into one of the installed one? | 14:49 |
| T42 | <elros34> I this is the one: https://github.com/mer-hybris/mce-plugin-libhybris | 14:49 |
| T42 | <elros34> you need some mce debug magic command | 14:50 |
| T42 | <elros34> from channel logs, maybe this one: mce -Tq -l plugin*:* -l sysfs*:* -l hybris*:* -l modules/led.c:* | 14:50 |
| T42 | <edp_17> Thanks @elros34. Here is the output: https://paste.ubuntu.com/p/rQqsqrXRsC/ | 15:06 |
| mal | you still have BackEnd = RGB | 15:08 |
| mal | sysfs-led-main.c: sysfs_led_probe_files(): led sysfs backend: N/A | 15:08 |
| mal | I told you to change that | 15:08 |
| mal | in /etc/mce/60-rgb.ini | 15:10 |
| T42 | <edp_17> Okay, I've amended that to be vanilla and now the wite led lit up however, there is no red, blue and green. I guess need to amend csd config for that too? | 15:14 |
| mal | csd config is different | 15:15 |
| mal | afaik | 15:15 |
| T42 | <edp_17> okay, I'll leave it then. Just reboot and see what happens. | 15:16 |
| mal | the csd config list what are supported in there | 15:16 |
| mal | and it's separate from mce | 15:16 |
| T42 | <edp_17> I see. | 15:16 |
| T42 | <edp_17> After reboot, the same happens. When I plug charger in, no led lit up. WIth csd, only white works it is blinking but when red/blue/green should be lit, only white is shown. Once I close the test the led turns yellow. I'll continue later. Thanks for your help so far! | 15:19 |
| mal | so check mce logs again, that last one | 15:20 |
| mal | and show the /etc/mce/60-rgb.ini file you have now | 15:20 |
| T42 | <elros34> max77843-rgb? don't you have poweroff issue on this device? Or crash at least in dmesg when writing to led_w/blink? | 17:11 |
| T42 | <edp_17> Yes, I do have power off issue. It always starts even if I shut it down. | 18:29 |
| T42 | <edp_17> Yes, leds do react when I echo a value in them. | 18:30 |
| T42 | <elros34> I mean that bug in my kernel was like: writing echo 0 > led_r/delay_on and then reading led_w/brightness trigger kernelcrash/reboot | 18:32 |
| T42 | <elros34> it's probably not related otherwis you you wouldn't be able to boot but still worth to try https://github.com/elros34/android_kernel_samsung_exynos7420/commit/c26cfa2775850723b869f7175ca1160e89180882 | 18:33 |
| T42 | <edp_17> I'll try this thanks. | 18:39 |
| T42 | <edp_17> Since I changed rgb to vanilla, white led does work. The others still don't. | 18:40 |
| T42 | <elros34> you need to run this mce magic command to see what is hapening during initialization and when you test | 18:43 |
| T42 | <edp_17> What's that mce magic command? | 20:00 |
| T42 | <elros34> same as previously: mce -Tq -l plugin*:* -l sysfs*:* -l hybris*:* -l modules/led.c:* but without this RGB backend set you have or even whole file not sure | 20:02 |
| T42 | <edp_17> Ah, okay. Thanks. | 21:13 |
