arno11KREYREN: most of them are in the wiki: https://leste.maemo.org/Nokia_N90000:29
KREYRENand those which ain't? :p00:30
KREYRENi am the kind of guy who would spent weeks of work to get 0.1% improvement00:30
arno11ah cool same as me lol00:30
KREYREN:D00:30
KREYRENit's passion art and a curse!00:31
arno11definitely. so to resume, you mainly need to block trackers from $HOME, use 500MHz as min freq, deactivate apt-worker and the important stuff missing is a custom transitions.ini file00:36
arno11let me find a link00:36
arno11https://github.com/Arno1103/leste-config/commit/ae3f5db00:40
Wizzupah yeah let's see if we can get these things in tomorrow, the swap as well, for 6.600:40
Wizzupsince I think we can put 6.6 in devel this weekend00:40
arno11ah yes could be really cool00:41
Wizzupmy n900 doesn't always boot well still, but this could be home wrt trackers or not havnig 500 as min freq00:45
arno11KREYREN: other tips: in the wiki there is the old overclock method using uImage: this way you can tweak dts and change voltage and freqs00:45
arno11Wizzup: ah ok00:46
Wizzupbut I also have *both* swaps atm since when I removed the emmc one I didn't get it to boot well at all00:47
Wizzupnot sure what's up :D00:47
arno11emmc is definitely buggy now but boot issue seems an 'unknown' stuff (mine doesn't boot well also)00:50
arno11i tried to remove everything i can and still have boot troubles00:51
KREYRENwhy is 500 as min frequency important? won't that hurt the battery life?01:12
KREYRENWizzup, elaorate on the fails to boot part? Mine sometimes boots without backlight on, but that seems to be due to getting it to boot via plugging in the USB cable instead of doing the power button that seems to be very important to charge capacitors to get proper display initialization01:13
arno11KREYREN: absolutely no impact on battery life01:14
KREYRENarno11, that sounds like it's breaking the laws of physics O.o01:14
arno11not really, there is a bias01:14
KREYRENWhat's the benefit of that? faster overall responsiveness and avoiding the annoying times when the apps loading and maemo seems frozen?01:15
arno11exactly01:15
arno11and avoid power draw during unresponsive times01:16
arno11but other things make it unresponsive: trackers, emmc swap (with kernel 6.6), blur effect in transitions01:23
KREYRENi see01:24
arno11and slow sd cards ofc01:28
KREYRENyea01:29
arno11tbh now it is quite easy to improve/solve. the difficult stuff with n900 is power management01:30
arno11long weeks needed for few mA lol01:30
dsc_arno11: ok, thanks01:31
arno11no probs01:32
KREYRENarno11, yea i imagine that NixOS would make things a lot easier for like the deep optimization, but getting hildon packaged will take some time01:34
KREYRENDo you get a good audio for SIP calls btw? mine is currently very unusable i hear like every 4th word and bad at that01:35
KREYRENi noticed that there is a command to change the pulseaudio priority though01:35
arno11yes it helps most of the time01:36
arno11and yes i get good audio with sip01:36
KREYRENDo you get more than 2G network?01:36
arno11yep 3.5g01:37
KREYRENsays 2G for me at all times in country which has 3G everywhere01:37
KREYRENcalls are much better with that chrt command, but still way too quiet and it seems to be loosing signal a lot01:39
arno11weird01:39
KREYRENoh it suggests Twinkle i am using the sphone thing01:40
arno11??? so you mean you got sound both ways with sphone/sip ?01:40
KREYRENyes01:40
arno11Wizzup: ^^^01:41
arno11great01:41
KREYRENis that not suppose to happen? :D01:41
arno11yep :D01:41
KREYRENlol01:41
KREYRENwas using that for phone calls for last 2 days kinda had to employ talking as if it was a very unreliable radio but it got the message across.. with the chrt it seems much better though01:42
KREYRENi just sometimes get the phone vibrating in my pocket and wont stop unless i reboot it though01:43
KREYRENwithout like anything on the display01:43
arno11ok that's an old bug being back01:44
arno11and when you say phone calls, you mean sip calls through sphone, right ?01:45
KREYRENyes01:46
arno11ok let's see what Wizzup and uvos think about that.01:47
KREYRENalso with those tweaks the phone feels like a modern flagship in terms of responsiveness :D01:48
arno11yes :D01:49
arno11did you try boost mode btw ?01:49
KREYRENnope how to enable it? though i kinda prefer the battery life01:50
arno11oh no worries, almost no impact (well...just a bit)01:50
arno11see overclock in the wiki01:51
arno11just 2 command lines to use boost mode01:51
KREYRENwill do though i should probably wait for the new battery as the one i am using is kinda really old and i fear that it won't be able to pull a lot of watts out of it01:52
arno11yeah ok01:52
KREYRENbought paxona branded one but it didn't arrive yet01:52
arno11ok01:53
arno11zzz time here01:54
arno11gn01:54
KREYRENwoah that boost is fast :D01:54
KREYRENgood night thanks for helps <301:54
KREYRENnow i just need a functional web browser and i am happy :D01:54
arno11you're welcome01:55
WizzupInteresting to hear that KREYREN gets audio in sip calls in voicecall manager11:15
Wizzupthat would be super welcome news, then we just need to figure out how he got it to work and what we need to change :)13:09
arno11Wizzup: i can confirm it works on my device as well. but only in one way (but with a very bad connection btw)14:01
arno11i'll try again when back to home14:01
Wizzupok, it might be time to rnu gabble with additional debug and compare our config/settings14:02
arno11ok14:08
Wizzupback in a few hours :)14:08
arno11me too14:08
arno11ttyl14:08
KREYRENSo i turned the boost mode on and it actually killed the battery xD Won't charge anymore15:56
KREYRENgood thing the replacement that should have much better health arrived today15:56
sicelothat shouldn't happen16:03
sicelothe won't charge anymore part, that is16:03
KREYRENsicelo, the battery is very old it was barelly hanging by, it seems that the increase of 0.2A is too much for it16:08
siceloi think that shouldn't prevent charging16:09
siceloanyway, you have a battery on the way ...16:09
KREYRENit's effectively charging at 1.4W atm and afaik the BMS cut out is 1.5W bcs it has too much of internal resistance now?16:12
KREYRENand it was at 1.58W charging before16:13
KREYRENtook like 14h to get full charge16:13
KREYRENalso heats up a lot16:14
sicelook16:14
KREYRENDid anyone tried to make a DIY battery for N900 before btw?16:17
KREYRENwas thinking about reverse-engineering the BMS and putting a lipo on it16:17
siceloi think you asked in #maemo the other day, or was it someone else? yes people have run the N900 on 18650 in 2S config for example16:19
KREYRENwasn't me16:19
KREYRENoh there is a whole forum post about it on maemo website :D16:19
KREYRENcool16:19
KREYRENThe diagram is kinda sketch16:20
KREYRENhmm it has 3 pins right do you need anything special sent on the 3rd pin for the data>16:20
siceloiirc it's meant to be a thermistor, whose resistance feeds an ADC in the phone. it's used to estimate the battery capacitance16:22
KREYRENi see16:23
sicelothere should be information about the average resistance you can put it (so no necessarily a thermistor)16:23
KREYRENso basically it tells the N900 when to stop charging when the battery is too hot right16:24
sicelonot really @ getting hot16:25
sicelounfortunately n900 charging & fuel gauge circuitry is a bit of a hack. tldr; the chip that does temp sensing for the battery is actually located in the phone, not in the battery16:26
KREYRENi see16:27
arno11KREYREN: 14h to get full charge ?...wow something went really wrong lol17:03
arno11usually boost mode has almost no real impact on a good battery (no excessive heat or high power usage)17:05
arno11at least on my device17:05
arno11btw 600 and 805MHz use the same voltage actually17:09
KREYRENarno11, it seems to have increased the power draw by 0.2 A which apparently was enough to finish it :D17:15
arno11200mA seems a lot17:17
arno110.2A @idle ? or doing something specific ?17:18
KREYRENarno11, how's the power consumption on your end? the pcb that i have in it atm was very hugged up when i got it so it's possible that somethign does too much resistance17:18
arno11pretty sure something is really wrong17:18
arno11most of the time with boost mode, it stays @500 600MHz as usual17:19
arno11and i've never seen such a power draw with higher freqs17:20
KREYRENarno11, would it be too much trouble for you to take the PCB out of the device and report to me the resistance on the test pads using a consistent ground? Would help me a lot to fix the other N900 which basically has a black spots over the PCB and lithography sparks on the antenna on the case17:20
KREYRENideally the ground on the hackerbus17:21
* KREYREN 's both N900 were saved from e-recycling service and he basically had to rework the whole PCB to get the device to work17:22
arno11sorry too much trouble for me: already have damaging parts on it :(17:22
arno11ah ok i see17:23
KREYRENyea i ideally need this from a device that is in mint condition :D17:23
KREYRENi will be open-sourcing the PCB so that should fix these issues after though17:23
arno11really ?17:25
KREYRENyep :p17:25
KREYRENi have plans to put a riscv SoC on it as well, but first i need to figure out the SOM solution https://git.dotya.ml/kreyren/OSHW-System-On-Module17:26
KREYREN(not up to date there is more work that i am putting together into a sensible standard)17:27
arno11ok, really cool btw17:28
KREYREN^^17:29
KREYRENthere is still like 2 weeks of work so hopefully in a month the SOM will be handled and then making the PCB is like 8 days of work17:30
KREYRENbcs just making exact copy would be too expensive to fabricate17:31
arno11ok, ofc17:32
KREYRENthe SOM fixes that by utilizing that lot of PCB fabricators will do up to 8 layer pcbs for 2 EUR and you get 5 of them, but they have to be below 50mm2 so putting that on a 2 layer board with spread out pins to be able to route it17:33
siceloyou're the one that asked for Neo900 files (gerber)? I've been asking myself where I remember your nick from17:39
arno11really interesting stuff17:40
KREYRENsicelo, ye17:41
KREYRENsicelo, h17:42
KREYRENsicelo, guy from the hackerspace that cooperated on the neo900 project was at our hackerspace yesterday even :D17:42
WizzupKREYREN: which hackerspace?18:59
KREYRENWizzup, Ours is Base48 and the german one is ChaosZone18:59
WizzupAh in brno19:04
KREYRENYe19:05
Wizzupbtw, I think the PA change for shm also fixed ringtone for me23:27
arno11it works again for me as well23:30
Wizzupmaybe we should try the 4? (or 8?) that FMG suggested23:32
WizzupI think I am still on 32 or 1623:32
arno11i tried 423:33
Wizzupworks well?23:33
arno11performances with emulators decreased23:33
arno11otherwise, no change23:34
Wizzupinteresting23:34
arno11yep23:34
arno11example:23:34
WizzupI will set 8 for now23:34
arno11with 64, picodrive can't run @60 fps + audio 44100 and need a bit of frameskip23:35
arno11with 32, works fine23:35
arno11with 4, same as 6423:36
Wizzupstrange23:37
arno11yep23:37
arno11maybe that's just a weird stuff with pico23:37
