L5 does not start charging on plugin of the original power supply

dos · March 30, 2022, 6:27pm

Hard to tell without knowing why it doesn’t charge in the first place.

guru · April 1, 2022, 5:34am

Last night I have had another such case. The battery level was around 30% and I tested two original power supplies (I have two L5). None worked. Then I did a reboot (without the power supply plugged in) and after this charging started as usual.

dos · April 1, 2022, 5:37am

An output of tail -n+0 /sys/class/power_supply/*/uevent gathered when plugged in but not charging could tell something more.

Captain_Morgan · April 2, 2022, 2:27am

had that happen to me once in two weeks, it was a little scary. i think the red charging light did not turn on when plugging in the charger.

reboot fixed the issue. the following likely wont show it since it has been a week:

Yeah, there’s no point in checking that when things work fine

There are a few reasons why charging may stop working until a reboot that come to my mind, and checking this command’s output while in that state could point us to which one is it.

Captain_Morgan · April 13, 2022, 11:18pm

@dos caught it:

Whats happening:

phone doesnt charge on charger and cable with or without PD,
phone lock shows solid red LED indicating charging but it isnt charging,
battery status indicator shows no charging or usb cable being plugged in while it is definately plugged in,
phone knows when usb is unplugged because sound over headphones disrupts briefly,

OK, could you keep it in that state for a moment while I’ll prepare next things to check?

dos · April 13, 2022, 11:27pm

It would be helpful it you could catch the output of:

sudo i2ctransfer -f -y 0 w10@0x3f 0x16 0x08 0xff 0xff 0xff 0xff 0xff 0xff 0xff 0xff
echo 1 | sudo tee /sys/kernel/debug/tracing/events/tps6598x/enable
sudo cat /sys/kernel/debug/tracing/trace_pipe

during plugging and unplugging the cable in this state. The last command is going to block and wait for events to come, which is when you should do the (un)plugging, so don’t wait for it to finish (you’ll have to ctrl+c it anyway when you’re done).

In any case, it appears that the USB-C controller gets confused for some reason. Now I’d like to see whether it’s its firmware (in which case we likely won’t be able to do anything with it) or the driver (which would be a good news, as we can fix it ;)).

Captain_Morgan · April 13, 2022, 11:28pm

let me try the other cable again, ok its not charging again

dos · April 13, 2022, 11:31pm

Also, please tell what kind of cable are you using. The original thread was about the charger provided with the phone, USB-PD is complex enough that we can’t even rule out the problem with the cable (some are violating the specs and can in turn be picky).

Captain_Morgan · April 13, 2022, 11:45pm

ok apparently thats not a PD cable (a cable i found in my drawer) , surprised it doesnt charge even without PD, the Purism cable works and charges. I maybe mistakingly thought it was charging before due to red LED.

irvinewade · April 13, 2022, 11:52pm

You will note

in your original configuration, for some reason it was only ‘negotiating’ standard USB-C power, not PD. In other words, either negotiation didn’t happen at all, or it did happen but it failed.

Why that is would be anyone’s guess … however I think the golden rule is: if you are having problems with charging, you must revert to the original Purism-supplied charger and cable for fault isolation.

Captain_Morgan · April 13, 2022, 11:55pm

Agreed it does not explain the red led charging indication though when not charging.

Captain_Morgan · April 13, 2022, 11:57pm

it was a non PD cable i am pretty certain of that now.

dos · April 14, 2022, 1:52am

Red LED indication is on whenever the charging controller receives external power. This, however, doesn’t necessarily mean that it’s getting enough power.

If you turned the phone off while connected to such source, it would actually be charging (although still a bit slowly).

BTW. There’s a fresh patchset that implements BC1.2 handling, which is often used with USB-A sources. It’s not merged yet: https://source.puri.sm/Librem5/linux/-/merge_requests/570

Captain_Morgan · April 14, 2022, 2:44am

@dos ok i think it is fine how it is- unless we would want to add any condition that results in a no or too slow charging situation to the slow blinking red light (failure to negotiate correct charging voltage, current etc).

Side note the unmerged kernel patch, there is no deb file so i imagine i cant sideload install this patch somehow to test?

dos · April 14, 2022, 2:25pm

As it is right now we don’t really control the red LED as it’s operated by the charger controller itself (although that could change in the future), but with the newest kernel (5.16.19pureos1) the battery icon in phosh and gnome-control-center should actually notice that the battery is getting slowly discharged instead of being charged and hide the bolt sign in that case.

Not sure what you’re talking about regarding debs, the package is there in CI job artifacts: https://source.puri.sm/sebastian.krzyszkowiak/linux-next/-/jobs/388541/artifacts/raw/debian/output/linux-image-5.16.0-1-librem5_5.16.19pureos1+gitlabci1_arm64.deb
