| sicelo | arno11, Wizzup : i got the N900 earpiece working :p | 00:14 |
|---|---|---|
| sicelo | but i really must sleep now, will share in the morning | 00:14 |
| sicelo | looking at the maemo kernel sources helped me solve it | 00:15 |
| sicelo | the asound.state: https://paste.debian.net/1289750/ | 00:19 |
| sicelo | i'm sure this needs some cleanup, but at least the sound works ;-) | 00:20 |
| * sicelo now has even stronger desire to get the FM receiver going - pity about the bluetooth :-( | 00:34 | |
| arno11 | sicelo: well done man ! | 08:55 |
| arno11 | sicelo: well done man ! | 09:02 |
| arno11 | channel seems to bug | 09:03 |
| sicelo | arno11: do test it and let me know if it works for you too | 09:57 |
| Wizzup | sicelo: wow, great! | 10:11 |
| wunderwungiel | Is it possible to boot Maemo Leste on N900 in different partitions configuration? I want boot partition to be 3rd partition and rootfs partition to be 4th partition | 13:18 |
| wunderwungiel | I guess changing U-Boot item file isnt enough | 13:18 |
| buZz | wunderwungiel ; yes | 16:28 |
| arno11 | . | 17:38 |
| arno11 | Wizzup: Leste irc log seems down | 17:39 |
| Wizzup | hm | 18:01 |
| arno11 | last message on log is from yesterday | 18:03 |
| arno11 | (and our messages from now are not appearing) | 18:05 |
| Wizzup | will fix, gimme a few mins | 18:06 |
| arno11 | ok :) thx | 18:07 |
| Wizzup | should work again | 18:25 |
| arno11 | yes thx | 18:27 |
| arno11 | Wizzup: sicelo: btw generic pwm-ir-tx seems a bit unstable and timers seems not perfect | 18:30 |
| arno11 | i mean pwm-ir-tx works when it wants to work and it seems not possible to send correctly a single pulse (sending quickly several same pulses works) | 18:33 |
| arno11 | repeating quickly the same pulse is the way i use to control my cd player for example | 18:35 |
| arno11 | so not ideal | 18:37 |
| sicelo | oh, that sucks | 18:41 |
| sicelo | maybe we should look at the old driver first and see if we can fix it? | 18:41 |
| arno11 | yes i think that's the best way | 18:41 |
| sicelo | however, we could also just ask linux-media to help us make the pwm-ir-tx work better | 18:42 |
| sicelo | but sure, if you think n900-ir is better option, let's look at it :-) | 18:42 |
| arno11 | yes because according to forums like raspberry ones, there are lot of troubles with pwm-ir-tx | 18:43 |
| sicelo | mmm, i see | 18:43 |
| sicelo | but then are we sure old driver wouldn't have these issues? | 18:44 |
| arno11 | yes i'm pretty sure | 18:44 |
| sicelo | if it really wouldn't have the issues, maybe whatever it does better should get ported to pwm-ir? | 18:44 |
| sicelo | let's see if we can grab the crash/oops from old driver, and take it from there | 18:45 |
| arno11 | yes agreed but how | 18:46 |
| sicelo | or do you have another idea how we can fix the older driver? | 18:46 |
| arno11 | maybe we can look on dts parameters first, it sounds really unclear | 18:48 |
| sicelo | < arno11> yes agreed but how --> well, Wizzup has serial, but he's got his hands full :-) | 18:48 |
| arno11 | ok :) | 18:49 |
| Wizzup | I will be home in ~5 days and have access to the serial | 18:49 |
| sicelo | i'm quite sure the dts is fine ... N900 is the only consumer for that older driver, so driver and dts are very unlikely to be out of sync | 18:49 |
| arno11 | cool | 18:49 |
| sicelo | arno11: i don't recall exactly where now, but something i read in the past led me to believe there's a timing issue with the older driver, responsible for that oops | 18:50 |
| arno11 | ok interesting because timing seems the main issue for the generic one as well (but with no oops) | 18:52 |
| sicelo | anyway, let's wait for the crash info. hopefully it will help us | 18:52 |
| arno11 | yes | 18:53 |
| sicelo | as far as the hardware/electronics goes, it's really just straightforward - IR LED connected via a transistor to a CPU pin | 18:57 |
| arno11 | yes really basic | 18:58 |
| arno11 | btw if we have the cpu pin number, another driver seems possible to use according to raspb forums | 18:59 |
| arno11 | gpio-ir-tx iirc | 19:00 |
| arno11 | anyway, crash info first lol | 19:04 |
| sicelo | is gpio-ir better? | 19:15 |
| arno11 | not sure | 19:24 |
| arno11 | but could be a third alternative just in case | 19:25 |
| arno11 | sicelo: i'm able to load gpio-ir-tx (already in the kernel) | 19:49 |
| arno11 | i'll try to use it (editing dts in a custom uImage just in case it goes wrong). back in a bit | 19:51 |
| arno11 | gpio-ir-tx doesn't work with original dts parameters (no surprise) | 20:45 |
| sicelo | arno11: yes gpio can't work. it's connected to a PWM line | 21:47 |
| sicelo | the CPU pin is labelled `GPT9 PWM` | 21:48 |
| arno11 | sicelo: ah ok so impossible to use | 21:57 |
| sicelo | yes. we either need to get pwm-ir to play along, or fix n900-ir | 22:00 |
| sicelo | i want to think asking the linux-media people for suggestions about the delays could help for pwm-ir. i haven't looked at both drivers in-depth, but i don't expect they're doing something completely different from each other | 22:01 |
| sicelo | will see if i can find time to look later on | 22:02 |
| arno11 | ok :) | 22:03 |
| sicelo | but it's the bluetooth that's stealing my interest now. unfortunately my skills for it are close to 0 | 22:05 |
| sicelo | arno11: i guess you'll prepare updated UCM2 files for Wizzup to include in Leste? you're the resident ucm expert here :p | 22:18 |
| Wizzup | for the earpiece? | 22:20 |
| sicelo | yes | 22:21 |
| arno11 | sicelo: :D it's too late for me today but tomorrow night it should be ready | 22:54 |
| sicelo | yeah no rush ;-) | 22:55 |
