13:23 <wunderwungiel> Is there some command like startxfce4 but starting Hildon on Leste through command line?

13:45 <Wizzup> I would look at what diejuse did

13:53 <wunderwungiel> Yeah I'm analyzing it right now

13:54 <wunderwungiel> I want to run Leste on Android without root, through proot on Termux, just like the distros from Andronix apps and similar

13:54 <wunderwungiel> For now I can access Leste's raspi2 image command line

13:54 <wunderwungiel> I once accessed the Hildon, but without any backgrouds, and colors. But I was able to launch apps. Now I don't remember what I exactly did and I can't repeat it :D

13:56 <Wizzup> so the geneic image I gave you didn't work?

13:57 <wunderwungiel> AlienDalvik on F(x)tec is arm32

13:57 <wunderwungiel> I will try yours image on S5e which is arm64 soon

14:02 <Wizzup> ah

16:58 <sicelo> Wizzup: https://lore.kernel.org/all/20230821152623.196541-1-sean@mess.org/

16:58 <sicelo> :-)

16:59 <Wizzup> great

16:59 <bencoh> neat

16:59 <sicelo> i decided to just email him and explain my findings, because i could see he was still active (in fact is the maintainer of the IR framework anyway) ... he offered to resubmit the patch.

17:00 <sicelo> bencoh: know a thing or two about alsa/asoc/dapm?

17:02 <bencoh> ehh ... I've read code and fiddled a bit, but not that much ... I'd be glad to help if I can :)

17:03 <sicelo> i'm trying to get the earpiece working, so with arno's great work, we can have 'normal' calls

17:03 <sicelo> i can see how this whole thing fits together, by looking at the schematics, and the driver

17:04 <sicelo> but so far i've not had success getting sound out of it

17:06 <bencoh> on n900 the earpiece is connected to cpu / audio codec, right? or is the audio from the modem routed to earpiece?

17:06 <sicelo> i can summarize it as follows: the earpiece is connected to an output of the 2nd codec (well, 2nd stage of the one codec). the input of this codec is hardwired to a mono output of the first codec

17:08 <bencoh> uhh

17:08 <bencoh> that's funky, but ... so be it

17:08 <sicelo> so in connection with modem audio, it will be cpu -> codec A -> DAC(A) -> mono out -> line2r (codec B) -> ... -> Left High Power Output (codec B)

17:09 <bencoh> so basically you should be able to just play audio from linux to that specific codec output to test it?

17:09 <sicelo> yes, that's what i've been doing

17:09 <sicelo> except, clearly i'm getting it wrong somewhere, since aplay hangs (which is normal if you've got the routing wrong)

17:10 <bencoh> possibly meaning that something should be enabled/powered first

17:10 <sicelo> i *think* both codecs are correctly powered

17:10 <bencoh> did you try dumping amixer output on fremantle and compare it to what you get?

17:10 <bencoh> also you can use /sys/kernel/debug/asoc

17:10 <sicelo> at least /sys/kernel/debug/asoc/ 'sees' both of them and can show the endpoint configurations

17:11 <bencoh> and /sys/kernel/debug/tracing/events/asoc

17:12 <sicelo> maybe the kernel i was testing with doesn't have correct stuff for tracing. last time tried, nothing showed up

17:12 <bencoh> you can enable it (/sys/kernel/debug/tracing/events/asoc/enable), then enable /sys/kernel/debug/tracing/tracing_on, and tail /sys/kernel/debug/tracing/trace_pipe

17:12 <sicelo> i'll check the config

17:13 <bencoh> I'd suggest enabling it if it's disabled, it can be very useful for that kind of stuff

17:19 <sicelo> thanks. i'll have a go at it again.

17:20 <sicelo> i can see jack insertion events

17:35 <sicelo> bencoh: the next question is probably: how to interpret the trace? :p

17:36 <sicelo> for example, https://paste.debian.net/1289596/

17:37 <sicelo> this one was not specific to earpiece ... just testing how the thing works

17:47 <sicelo> previously i had looked at /sys/kernel/debug/tracing/trace , so i guess that's why i never saw anything useful

17:49 <sicelo> arno11: so it looks like we have no alternative - BT really *must* work before the fm receiver works

17:51 <sicelo> while it has i2c access, by default it's ... dead. i2cdetect won't find it. to turn on the i2c access, you need to send it a specific bluetooth command :p

17:59 <arno11> ok

18:07 <arno11> btw i successfully ported Pierogi ! the app works fine (like Fremantle but a bit slower), able to send pulses (visible with a phone camera) but pulses seems a bit too slow to be recognized well (that's a well known issue with pwm-ir-tx...). I got better results with LIRC/irsend because it's easy to repeat pulses quickly

18:08 <sicelo> https://github.com/maemo-leste-extras ... add it here :-)

18:08 <arno11> giving higher cpu priority could maybe solve the issue (?)

18:09 <arno11> yes (for maemo-leste-extras)

18:13 <arno11> Anyway i learned so many things about maemo qt4->qt5 port :) probably useful to share on TMO

18:14 <sicelo> or wiki

18:14 <arno11> oh yes

18:30 <arno11> sicelo:(about FM/Bluetooth) <to turn on the i2c access, you need to send it a >

18:30 <arno11> is it an AT command ?

18:32 <sicelo> no, this is it: 0x08, 0x15, 0xFC, 0x03, 0x29, 0x00, 0xa2

18:32 <sicelo> disabling is the same, just 0x7F at the end

18:36 <arno11> argh ok

18:37 <sicelo> Fun

18:37 <arno11> yes

19:00 <arno11> sicelo: (for earpiece stuff) did you have a look at alsa/pulse config ?

19:01 <arno11> i just remember seeing specific alsa module earphone parameters in default.pa in Fremantle iirc

19:07 <arno11> got it. /etc/pulse/default.pa : load-module-alsa-sink-volume sink_name=sink.hw0 mixer_load=HP_DAC,Headphone,Earphone mixer=HP_DAC device=hw:0

19:10 <arno11> sounds weird. i think even if we activate earphone we will have troubles to set up the volume

19:11 <arno11> or maybe earphone is already working but with volume at 0

19:12 <arno11> another question: why alsamixer/amixer shows earphone ON/OFF but not the Volume like in Fremantle ?

19:15 <sicelo> That enables the function

19:23 <arno11> this module seems specific to volume.

21:14 <sicelo> btw arno11 , here's a fun thing that can be done with n900 and its sound card, https://talk.maemo.org/showpost.php?p=1062144&postcount=1

21:23 <arno11> !?! wtf, really cool

21:33 <arno11> it means we can probably plug something like a cd player with a specific adaptor (rca to jack)

21:34 <arno11> i think i have one, i'll try :D

21:37 <sicelo> just make sure you lower the volume first

21:37 <sicelo> and of course, you won't get stereo

21:46 <arno11> not sure for stereo, i mean using a double rca red-white / jack stereo

21:48 <arno11> or maybe the original n900 cable works in the 2 ways lol

21:49 <sicelo> you can't get stereo audio, simply because this trick basically connects input audio as if it was headphone mic

21:50 <sicelo> that's why the thread says to not push the connector fully in

21:50 <arno11> ok makes sense
