| uvos | freemangordon: kernel with CONFIG_IIO_SYSFS_TRIGGER is on the way | 00:04 |
|---|---|---|
| Wizzup | uvos: did you also pull the n900 debugfs thing? | 00:29 |
| Wizzup | arno11: if you want to be directly included in these voice call mails, please lmk what email you'd want to be mailed at | 00:49 |
| Wizzup | actually my bionic is still on beowulf | 00:56 |
| Wizzup | I want to test a few more things on it that broke in the chimaera update | 00:56 |
| Wizzup | (syncevolution) | 00:56 |
| Wizzup | sicelo: I think a UCM2 for the n900 will probably help with the calls too eventually | 01:00 |
| Wizzup | uvos: btw qtwebbrowser does run on the n900, albeit it very slowly | 01:02 |
| Wizzup | at least for static pages | 01:02 |
| Wizzup | it seems the touchscreen as mouse pointer though, so no scrolling | 01:02 |
| Wizzup | scrolling with arrows has <1s response time | 01:03 |
| tmlind | uvos: not quite sure what omapdss register that was, i think i only tinkered with the sgx clock speed | 07:07 |
| tmlind | Wizzup: false alert on the dss blank/unblank test, it was just the ssh connection over wlan that was timing out, no reboots seen | 07:07 |
| tmlind | need to try that also with sgx enabled though | 07:08 |
| Wizzup | tmlind: ок | 11:13 |
| Wizzup | er, ok | 11:13 |
| Wizzup | uvos__: how do you use bt on the d4/bionic? | 13:11 |
| Wizzup | like, with what devices, and when do you start/stop it | 13:11 |
| Wizzup | I'm still baffled that you don't get these modem drops that I see shortly after using bt | 13:11 |
| antranigv | hey al | 17:33 |
| Wizzup | hi | 17:35 |
| antranigv | silly question: I have a Nokia N900, but I don't remember what I've done with it. it just booted fine, but I don't remember if I used a custom bootloader, or anything. do I need to reset it before installing Maemo Leste? | 17:37 |
| Wizzup | I think you need to set up u-boot on it, easier to do with fremantle | 17:38 |
| antranigv | Wizzup hi! long time no see :)) | 17:38 |
| Wizzup | but the wiki has instructions on how to try it without changing anything | 17:38 |
| antranigv | looks like I need an SD card. time to turn the house upside down! | 17:39 |
| antranigv | Wizzup should I download maemo-leste-1.0-armhf-n900-20230326.img.xz ? wait, when did you reach v1.0? :D | 17:42 |
| Wizzup | 1.0 was always in the images | 17:47 |
| Wizzup | that image ought to boot, yes | 17:47 |
| antranigv | I wonder if there's a way in shell to alias an operator | 18:01 |
| uvos | Wizzup: i just modprobe the module by hand | 19:26 |
| uvos | start the bluetooth serivce | 19:26 |
| uvos | and thats it | 19:26 |
| uvos | autoconnects with my qcII hadphones i paired using blueman-manager | 19:26 |
| uvos | I have never seen the modem drop away at all - ever | 19:26 |
| uvos | btw i know the kernel build yesterday failed | 19:27 |
| uvos | i tagged the wrong thing, ill fix it in a bit | 19:27 |
| Wizzup | uvos: ok, I wonder if it is thermal related or something | 20:03 |
| uvos | Wizzup: well i did on occasion play openlara with audio going via bt | 20:12 |
| uvos | the device can hardly get any more loaded than that | 20:13 |
| Wizzup | I mean, I see it on both my d4 and bionic, so it can't be a hw defect | 20:13 |
| Wizzup | at least it's very unlikely | 20:13 |
| uvos | i gues you elliminated all other differences | 20:13 |
| uvos | i also have used several d4 | 20:13 |
| uvos | never seen it | 20:13 |
| uvos | so no hw defect is unlikely | 20:13 |
| Wizzup | do you customise much beyond the normal image | 20:14 |
| uvos | the other differences would be: my specific bt client (ok this one is hard to repo), my sim and operator being 2g only, | 20:14 |
| uvos | nothing related to the modem | 20:14 |
| uvos | i dont use telepathy maybe it causes ofono to issues some qmi commands that the modem dosent like or something | 20:15 |
| Wizzup | my bionic is on 2g here usually | 20:17 |
| Wizzup | I also didn't have tp there per se | 20:17 |
| uvos | Wizzup: well my sim not even having umts entries means the modem probubly dosent even scann for umts | 20:18 |
| Wizzup | mhm | 20:21 |
| Wizzup | I think the bionic does the same unironically :P | 20:22 |
| Wizzup | I can't get it to go into 3g mode even though it should | 20:22 |
| uvos | i mean bionic may just have poor reception on your umts band | 20:32 |
| uvos | its not intendet to be used on these bands after all | 20:32 |
| tmlind | hmm getting this now on doing dist-upgrade: dpkg-divert: error: 'diversion of /lib/udev/rules.d/85-input-devices.rules to /lib/udev/rules.d/85-input-devices.rules.leste-orig by leste-config-droid4' clashes with 'diversion of /lib/udev/rules.d/85-input-devices.rules to /lib/udev/rules.d/85-input-devices.rules.leste-orig by leste-config-mapphone' | 20:35 |
| uvos | yeah sorry about that | 20:36 |
| tmlind | any idea how to fix? | 20:36 |
| uvos | yeah you need to undisplace that file | 20:36 |
| tmlind | so how does one undisplace? | 20:37 |
| uvos | good question i dont quite remember the command amt | 20:38 |
| uvos | atm | 20:38 |
| uvos | Wizzup: ^^^^ | 20:38 |
| tmlind | dpkg --undisplace maybe? :) | 20:38 |
| uvos | that sounds correct | 20:38 |
| uvos | dpkg-divert --remove /lib/udev/rules.d/85-input-devices.rules | 20:40 |
| uvos | tmlind: ^^^ | 20:40 |
| tmlind | thanks | 20:40 |
| tmlind | ok up to date now i think assuming beowulf is still the current version | 20:42 |
| uvos | no | 20:42 |
| uvos | we are all on chimaera | 20:42 |
| tmlind | ah ok will update to that then | 20:42 |
| uvos | yay resonably modern pacakges | 20:43 |
| tmlind | nice | 20:43 |
| freemangordon | uvos: have you ever built a graphic of the battery SoC approximation function? | 20:49 |
| uvos | a graph? no why | 20:49 |
| uvos | but this shal not be hard no? | 20:49 |
| uvos | what do we need this for? | 20:49 |
| freemangordon | as either I am doing something stupid or that function is useless | 20:49 |
| uvos | hmm | 20:50 |
| uvos | what function exactly are we talking about? | 20:50 |
| uvos | the one in charge-mode is not so great, we know this | 20:50 |
| freemangordon | fuel_level_LiIon | 20:51 |
| uvos | dident you come up with an improvent | 20:51 |
| freemangordon | yes, I did | 20:51 |
| freemangordon | but now I question the function | 20:51 |
| freemangordon | sec | 20:51 |
| freemangordon | uvos: http://95.43.220.235/leste/liion.png | 20:55 |
| tmlind | getting some dist-upgrade errors after changing to chimaera: | 20:56 |
| tmlind | E: This installation run will require temporarily removing the essential package hildon-base:armhf due to a Conflicts/Pre-Depends loop. This is often bad, but if you really want to do it, activate the APT::Force-LoopBreak option. | 20:56 |
| tmlind | E: Reverse conflicts early remove for package 'elogind:armhf' failed | 20:56 |
| freemangordon | hmm, actually it is not *that* bad | 20:56 |
| freemangordon | tmlind: do as it says, activate the option | 20:57 |
| tmlind | freemangordon: ok thanks | 20:57 |
| uvos | freemangordon: i mean this dosent look totaly unresonable | 20:57 |
| uvos | a bit high in the middle | 20:57 |
| freemangordon | uvos: so, it is very, very bad at the linear approximation part (the straight line @ 20%) | 20:58 |
| freemangordon | between 20 and 10 % we shall have something else | 20:58 |
| uvos | i mean if you look at a typical lip dscharge curve | 20:59 |
| uvos | this bit is alot steeper | 20:59 |
| freemangordon | see https://www.powertechsystems.eu/wp-content/uploads/sites/6/2018/11/LiFePO4-vs-Lead-Acid-Discharge-Curve-EN.png | 20:59 |
| freemangordon | right | 20:59 |
| uvos | i dont think the function is totaly out of wack, i doubt you can do mucht better than 10% without mesureing the discharge curve for the battery that is installed | 21:00 |
| uvos | so +-5% | 21:00 |
| freemangordon | hmm | 21:01 |
| freemangordon | anyway, I think I now measure Ri with much bigger precosion | 21:02 |
| freemangordon | for the battery here it is Ri ~= 0.12 | 21:02 |
| freemangordon | depends on the current ofc | 21:03 |
| freemangordon | but not much | 21:03 |
| tmlind | freemangordon: also the 1-wire chip on the battery consumes some minimal amount of power that we're not measuring in addition to the 20mohm shunt resistor | 21:03 |
| freemangordon | you mean a couple of mV that we don;t account for? | 21:04 |
| tmlind | yeah, i think it's a ds2450 on the battery, the datasheet might say how much it consumes | 21:05 |
| freemangordon | but, that should be part of Ri, no? | 21:06 |
| freemangordon | I mean - no matter how many resistors we have before the stunt, they are all part of Ri that we calculate based on the measurements | 21:06 |
| tmlind | i guess, the datasheet for ds2450 says 25 μW idle | 21:07 |
| tmlind | battery voltage is sampled before the 20mohm shunt though | 21:08 |
| freemangordon | umm, no | 21:08 |
| * freemangordon checks the datasheet | 21:08 | |
| freemangordon | oh, right | 21:09 |
| freemangordon | but thats ok, no? | 21:09 |
| tmlind | i guess just trying to list what all is outside the pmic | 21:09 |
| tmlind | see mc13783 8.1.1 dual path charging for the shunt, i think BATT is what the adc measures, then your 2x4 also uses BATTISNS | 21:12 |
| freemangordon | yes | 21:12 |
| tmlind | and then the ds2450 is before BATT | 21:12 |
| freemangordon | yes | 21:13 |
| tmlind | ok | 21:13 |
| freemangordon | but, we can account it as part of Ri | 21:13 |
| tmlind | ok great | 21:13 |
| freemangordon | because we don't really care about the internal structure of the battery | 21:13 |
| tmlind | ok | 21:13 |
| uvos | i mean if its very inductive it might throw you off | 21:19 |
| uvos | since you assume the battery is a first order thevenin model | 21:20 |
| freemangordon | I am doing lots of non-linear filtering, so spikes does not do much damage | 21:20 |
| freemangordon | hmm, wait | 21:21 |
| uvos | ok | 21:21 |
| freemangordon | actually it is not that bad | 21:21 |
| freemangordon | because 100% full for the driver is ~95 for 'us' | 21:21 |
| freemangordon | because driver stops charging before OCV hits 4.2V | 21:22 |
| uvos | ofc | 21:22 |
| uvos | since charge terminateion is based on current dropping below some thresh while charge voltage is 4.2 | 21:22 |
| freemangordon | mhm | 21:22 |
| uvos | nessecarly this means that ocv is a bit below 4.2 | 21:23 |
| freemangordon | right | 21:23 |
| freemangordon | which we account as 95%(or similar) full | 21:23 |
| freemangordon | so driver reports a bit highr value | 21:23 |
| freemangordon | *higher | 21:23 |
| freemangordon | ok, I'll capture a couple of discharge curves (driver vs algo) for idle, medium and full load | 21:24 |
| freemangordon | charge curve as well | 21:24 |
| tmlind | that will be fun to see :) | 21:29 |
| freemangordon | mhm | 21:29 |
| freemangordon | but will take time | 21:30 |
| tmlind | yeah.. i'll leave dist-upgrade running here, ttyl | 21:33 |
| freemangordon | ttyl | 21:33 |
| uvos | your lucky your not updateing a n900 | 21:33 |
| freemangordon | heh | 21:34 |
| tmlind | yup.. later | 21:34 |
| krolden | hello | 22:34 |
| krolden | any chance to run maemo on photon Q (xt897)? would the droid 4 image work or do i need to build? | 22:35 |
| krolden | im gonna try a sailfish image but looks like it has a hard time dealing with the lack of ram | 22:37 |
| Wizzup | is it omap? | 22:44 |
| Wizzup | the droid 4 img won't work I think | 22:44 |
| krolden | no ive been reading in the irc logs i just found after i joined lol | 22:45 |
| krolden | https://libera.ems.host/_matrix/media/r0/download/connolly.tech/vywfbjfkhdzfoIXnKYZyrIxl/IMG_20211113_010422.jpg looks like fun | 22:45 |
| krolden | buddy just sent me one for free and im loving it. great slide mechanism | 22:50 |
| krolden | no sim card slot without mod tho | 22:51 |
| Wizzup | yeah | 22:55 |
| Wizzup | I have one at home but had no time for it | 22:55 |
| Wizzup | I sent one to a guy in the UK | 22:55 |
| Wizzup | I don't know if he did much with it | 22:55 |
| krolden | its too bad the screen is nicer than the droid 4 | 22:57 |
| krolden | gonna give sailfish a shot | 22:58 |
| krolden | always wanted to try meego | 22:58 |
