joschls1028a is still in berlin according to ups tracking :(16:52
joschscheduled or arrival on thursday16:52
joschfolks seems to be having a long weekend :)16:52
joschminute: could we quickly revisit the decision to not preserve ${bootargs} in ubootenv.d/00reform2_ubootenv? I've now come across a few forum posts like https://community.mnt.re/t/screen-goes-black-after-boot/1653/7 which suggest to add XY to ${bootargs} to see if it fixes the problem. grepping the IRC logs it happened a few times that you or others suggested to edit the cmdline this or that way to try 16:55
joschsomething out. If ubootenv.d/00reform2_ubootenv does not respect ${bootargs}, then there is no good way anymore to do any of this other than editing ubootenv.d/00reform2_ubootenv itself which is bad advice as that file is not meant to be edited by the user (because it will be overwritten during the next upgrade). Stuf in /etc like /etc/default/flash-kernel is meant to be user-controlled configuration 16:55
joschbut now gets ignored.16:56
joschI understand the motivation to make sure that no bad kernel option ends up in the final cmdline but this also takes away quite a bit of flexibility and i think it would be surprising to some users why the value they set in u-boot env is not picked up by the kernel. This already happened a few days ago.16:56
joschThe platforms that must not receive the default /etc/default/flash-kernel for imx8mq have their own system image that ships without /etc/default/flash-kernel anyways, right? So respecting ${bootargs} would only be a problem for people who migrate their system from one SoM to another without adjusting or deleting their /etc/default/flash-kernel. Is that enough of a reason?16:58
joschwell, what i meant as "quickly" became a wall of text, sorry XD17:06
sevanit's just a case of having an up to date v3 system image & doing the hardware swap when the thing arrives?17:16
joschsevan: not quite because the hardware you swap contains your /boot partition on its emmc :)17:18
joschwith sysimage-v4 though you can have the exact same rootfs and only have /boot differ17:18
sevanah, right.17:23
minutejosch: oooh true there is a holiday wedged in between17:25
minutejosch: i can follow your reasoning, and agree... it is mainly a problem for existing installs. 17:26
minutejosch: i need to check if ls1028a and a311d don't have any "bad" default bootargs17:27
joschyes, if it is only a problem for people migrating to another SoM, removing or changing /etc/default/flash-kernel could just be one of the steps in the documentation that explains how to move from imx to a different SoM17:56

abortretryfailwoah, my Reform drained its batteries down to 1.6V yesterday... wtf21:00
BoostisbetterOh really? DO you have the new battery save boards?21:01
abortretryfailno, it wasn't an option from CrowdSupply when I got it this spring21:02
BoostisbetterIf you can I would recommend picking those up, they specifically prevent this kind of draining. 21:02
abortretryfailI think I put it to sleep Sunday morning and went out. Then I grabbed it today just now to use it and it was totally dead.21:03
Boostisbetteryeah that really sucks. However, the Reform will run with no batteries in at well. 21:04
BoostisbetterThere is a chance you might be able to revive the cell though. 21:04
Boostisbetterminute or josch would know better than me on the specifics there though. 21:04
abortretryfaili'm familiar with the process. I rescue totally "dead" cells from salvage laptop packs all the time. It's just surprising to see them that low.21:05
Boostisbetteryeah21:06
abortretryfailIt's charging right now with -1.47A so i don't think they need rescue 21:06
Boostisbetteryeah that sounds good. 21:06
Boostisbetterseems like you dodged a bullet on that one. 21:06
abortretryfailI just wonder *why* it did it21:07
Boostisbetterthere is no under voltage protection in the original battery boards. 21:09
Boostisbetterhence the revision and upgrade.21:09
Boostisbetterthe Reform has incrementally improved a lot, but with steady changes over a period of time. 21:10
abortretryfailthe lpc has low voltage shutoff stuff in the code, i wonder if it got stuck or hung somehow 21:10
BoostisbetterJust be mindful that this is something that can happen in the future, until you get the new battery boards. 21:11
abortretryfailyeah, not putting it to sleep again until i get those.21:13
Boostisbetterminute: the wifi card supplied with the Reform does not do Bluetooth right?21:14
abortretryfailmine doesn't21:14
minuteBoostisbetter: it does not.21:14
Boostisbetterabortretryfail: it will do it when not in sleep as well. 21:14
Boostisbetterjust needs to be on a charger if not going to be used for a long period of time (read more than 8 hours)21:14
Boostisbetteror off21:15
abortretryfailBoostisbetter: so the undervoltage state in the lpc code doesn't turn off the SoM correctly then?21:15
Boostisbetterminute: any advice on what software I can install to control a BT plugable dongle?21:16
Boostisbetterabortretryfail: I am not sure of the specifics, I just know that undervoltage protection was not working correctly on the previous battery boards. 21:16
minuteabortretryfail: it normally does, but then the batteries are already at the edge, and there is some ongoing drain (although quite small) from LPC waking up periodically21:16
minuteabortretryfail: there was also a design error which makes the system turn _on_ in a very low voltage situation21:17
abortretryfailI bet that's what happened. I doubt the LPC could have drained them that low on its own21:17
minuteabortretryfail: i.e. there's a UVLO resistor on the LPC's power supply. but that's not good because the LPC keeps the main regulators _off_. if it doesn't run, they turn on21:17
minuteabortretryfail: a workaround is to remove this uvlo circuit and make sure EN on 3v3 standby regulator is always pulled up21:18
abortretryfailFixed in MB 2.5 like the headphone jack's decoupling caps? 21:19
minuteyep21:19
minuteand also the protected battery boards are included in all new builds (since we launched them)21:20
abortretryfailI'll have to take a look at the schematic and see if i can fix that too. I was planning on tacking some extra capacitors on to fix the headphone bass anyway.21:21
abortretryfailBoostisbetter: re: bluetooth, I just use bluetoothctl21:22
abortretryfailnever had great luck with the tray applets 21:23
Boostisbetterdoesn't seem to be in the Debian repo. Or is it under a different package name?21:23
abortretryfailpart of bluez i think21:25
minuteBoostisbetter: blueman-applet / blueman-tray / blueman-manager21:29
minuteit also ships with the standard config of sys image v4.21:30
Boostisbetterthanks! bluetoothctl doesn't seem to support audio agents21:34
Boostisbetterminute: any idea what the package name for those are? Because trying to install it with blueman is using bluez components instead of blueman elements you mentioned. 21:37
Boostisbetterminute: disrregard. was just blueman. 21:44
BoostisbetterI was just getting thrown off that it was saying it was including bluez, but it turns out that blueman utlitzes that for the backend work. 21:53

joschconcerning the system switching off when volatage is too low i once had the funny situation that i had the system on and had forgotten to put the plug in22:23
joschwhen i came back it was off of course but i did not yet realize that it was off because i forgot to plug it in22:24
joschso i switched it on and it managed to boot, i entered my luks passphrase, then logged in22:24
joschthen in sway i noticed the battery status22:24
joschi reached to the power cable and that's when it went off again22:24
minuteeek22:26
joschmy system switches off at around 9-10% according to the oled (which shows the identical value as sway) so when sway showed me 9% remaining after having booted i thought i had a few more seconds to get the cable than i actually did :D22:28

sevanthis doesn't affect the Reform but I'm mentioning it since it's for the standard SATA version of SSDs (not m.2) but the WD Green drives have a new firmware for critical issues, and I realised the only way to update it is with a machine running Windows, what a faff. https://support-en.wd.com/app/answers/detailweb/a_id/51127/h/p222:39
sevanI do have a WD Black installed in my reform however. No recent version of Windows, nor a PC with nvme slot onboard.22:40
sevanI think I'm complaining about WD's firmware update mechanism in the room for mnt-reform. ignore. ;)22:42
joschremember the days when you bought hardware and the firmware that came with it was just it forever? :)22:44
sevanneed more EEPROMs!22:45
minutei personally use wd blue 2tb in my reform22:59
sevanI went for the black because it was on sale I think. there's some impressive heatsinks on some of these drives. very fashionable :)23:04
sknebelIf you push them NVMe drives can use cooling, its not entirely pointless/for show23:06

sknebeldont get me started on weird logos and slogans on hardware ...23:08
sevan:D23:08
joschhonestly, i'd be happy to have the MNT on my reform a bit more visible than it is23:08
sknebellike I sort of get the entire thing with PCs with windows in them and cool looking hardware... except 90% of high-end stuff is plastered in what amounts to ads23:08
joschit annoys me to be a walking advertisement for IBM, Lenovo etc but having an MNT device makes me quite proud to show off23:09
sknebelyou could line it with something23:09
sknebelbeen thinking about copper tape23:09
Zabanobody ever got fired for buying MNT23:09
minuteperhaps one could make a different screen back that has some perforation along the logo23:09
minutethe innolux display at least is open at the back and provides a light to the back23:10
sknebela PCB that snugly fits in it would also be fun, if you get a really thin one it could fit into the recess (without components of course)23:10
sevanZaba: <323:11
sevanminute: will things eventually lead to an animated started up logo, just like in the laptop scene from hackers? I hope so :)23:14
minutesevan: hehe23:18
BoostisbetterI don't know team, I feel like the MNT logo on the Reform is perfect as is. I think the clear bottom is the biggest logo there could be for MNT. 23:18
BoostisbetterI'm pumped about the pocket though, and I am happy that it doesn't have a see through something because we need durability even more on a mobile device. I think it is going to be awesome. 23:19
BoostisbetterReally looking forward to getting my pocket all set up as well as I have the Reform. 23:19
joschBoostisbetter: do you follow Lukas on mastodon? There were some new Pocket posts today. :)23:32
Boostisbetteryou bet I do. Let me check them out. 23:36
Boostisbetteraww yeah! 23:37
