#rockbox log for 2012-05-27

00:06:52*bertrik gets confused
00:07:37bertrikthe OF only touches the offset register, but RB does that too, so there's no way to set the RTC seconds directly now
00:07:58pamauryright
00:08:21pamaurythat's why you should avoid touching seconds or roll it back to some reasonable value. Otherwise the OF won't be too happy
00:09:11bertrikthe offset2 register is now at 10 years offset and the RTC seconds registers is now in 1980 epoch
00:09:31pamaurythat's probably ok
00:11:45bertrikit would make sense to me if the offset register was near 0 not near +10 years
00:12:54pamauryyou can do what you want I guess, it doesn't really matter
00:13:34pamauryin the end, the OF probably uses this mechanism to prevent time roll back so it will keep the offset near 0 when you play DRM'd file ?
00:15:52 Quit lorenzo92 (Remote host closed the connection)
00:17:34bertrikOTOH, you said the OF doesn't handle negative offsets, so perhaps its kept at a seriously positive value
00:17:50CIA-79Commit fca9e7b in rockbox by 03Bertrik Sikken: zenxfi3: RTC is used in same was as in fuze+, using seconds-since-1970 plus an offset

00:20:27CIA-79fca9e7b build result: All green
00:26:19pamaurystill no luck with dri and audio, dma is not starting, I must be missing something
00:26:40bertrikthe stfm1000 driver has some code to setup the dma
00:27:15bertrikperhaps a clock gate somewhere?
00:28:03bluebrotherhmm. genlang writes a subheader for each "user", but where does it write the number of users? We have "core" only right now, but well ...
00:36:08bertrikI must be doing something wrong, it looks like plugins are disabled for the zenxfi3, yet they are built anyway
00:36:46bertrikmaybe "no" is interpreted as "yes" and I should just provide an empty string instead
00:37:22bertrikah, that was it, it appears
00:40:48CIA-79Commit 2fb4fe9 in rockbox by 03Bertrik Sikken: zenxfi3: disable building of plugins ("no" means yes, use an empty string instead)

03:52:14rocktriangleHello everyone, I was thinking of buying a fuze + but it seems it's not up to date with rockbox
03:52:59rocktriangleSo I was wondering whether or not I should buy it keeping in mind that I'd ONLY buy it knowing that sooner or later, it'll have rockbox
03:54:46rocktriangleI was also wondering if it's possible to tweak the contrast for my clip+ (same brand) since it's painful to look at it in the dark.
03:58:23Kaiscenefor adjusting the brightness on the clip+ here's the setting: Settings > General Settings > Display > LCD Settings > Contrast.
04:00
04:01:27rocktriangleIt exists, I'm aware.
04:01:34rocktriangleHowever I want it to even further down.
04:03:36rocktriangleLike I've written earlier, it's quite problamatic that the minimal light is quite bright, enough to blind me from seeing my natural surroundings in the dark.
04:03:58rocktriangleI'd rather not look at it, only to have my eyes adjust again, hence why I need the contrast to go further then what 0 states.

15:25:18rocktriangleMy DAP won't turn on properly and I don't know how to troubleshoot, who do I go to
15:25:19rocktriangle?
15:28:26rocktriangleThis is all rockbox related.
15:28:39rocktriangleOnly the original firmware could be booted.
15:28:42rocktriangleWhat do I do?
15:28:51gevaertsIt can't be. Rockbox doesn't run on unspecified players.
15:29:08rocktriangleHeh, very funny.
15:29:28funmando you see bootloader messages ?
15:29:49rocktriangleI used to get one with numbers and letters but now all I get it "undefined instruction"
15:30:23rocktriangleI can tell you what was different today that I didn't do before .
15:30:52funmando you use current build?
15:30:58rocktriangleI've had some sort of problems adding this one extra microSD card, it often came up with problems.
15:31:03rocktriangleYes I did.
15:31:18funmanwell try booting without the card inserted
15:31:26rocktriangleSame problem.
15:31:31rocktriangleSame result.
15:32:51rocktriangleOh my, without the chip it's a worse result. All I get is a black screen and by pressing any button it reboots itself.
15:33:40rocktriangleYAY
15:34:01rocktriangleI turned it on to the default firmware and back to rockbox and I got an error message.
15:34:11rocktriangleSWI at 34EA0004
15:34:46funmanwhich version is it exactly: 872a3a7 ?
15:35:01funman
15:35:27funmanwell, we dont use SWI and we also dont use 34ea* addresses so something is seriously fucked up
15:35:30rocktriangleI have no idea what you're talking about but can you tell me how to find out?
15:35:45funmani suggest moving .rockbox to .rockbox-bak and extracting the build again
15:36:10rocktriangle.rockbox-bak?
15:36:11funmanelse like gevaerts we dont know which player it is. i just know you mentioned the clip+ yesterday
15:36:26rocktriangleYup, that's all I have.
15:36:41rocktriangle(that can support rockbox)
15:38:00rocktriangleOnce again I set it to the original firmware and back to rockbox and once again I get "undefined instruction"
15:38:08funmanformat it and reinstall
15:38:21rocktriangleFormat the entire thing?!
15:38:56funmanformat, or delete .rockbox/ directory/folder - whichever is simpler
15:39:10rocktriangleAlong with the music in it?
15:39:58rocktriangleNow here's the problem, it's not being recognize by the computer.
15:40:48funmando it from the OF then
15:41:00rocktriangleThank you, I tried 2 seconds ago, it worked.
15:41:49rocktriangleWow
15:41:57rocktriangleBelieve it or not, the .rockbox folder is gone
15:43:05rocktriangleMany of the folders that came wit hte OF are also gone
15:43:13rocktriangleWhat do I do?
15:44:07rocktriangleMy guess: reboot it with the clip+'s latest firmware update then install rockbox on it
15:47:04***Saving seen data "./dancer.seen"
15:47:33rocktriangleand possibly format it on the OF to factory settings

18:07:27pamaurybertrik: I managed to "plug" the dri dma output to the dac one but I don't get anything useless
18:07:30pamauryjust noise
18:07:57pamauryalso I'm pretty sure the dri one has a much higher rate (like ~4Mhz) and the format is unsure
18:08:33bertrikThe radio doesn't seem to be very configurable (at least not in the linux stfm1000) with respect to dri configuration
18:09:20bertrikbut indeed I think I read several config options on the SoC side, for number of bits, alignment, etc.
18:09:38pamauryI'm trying different dma configuration like looping on a buffer of size X for DRI and the same buffer of size Y on the DAC so that X/Y gives the correct rate ratio
18:10:06pamauryI've sent a mail to creative to ask them the datasheet, we never know
18:10:24bertrikgood
18:15:05pamauryactually, I'm wondering how the linux driver gets RDS. Because the RDS stream is not at the same frequency as the audio signal right ?
18:18:46 Join Totalled [0] (~Totalled@c-98-245-9-211.hsd1.co.comcast.net)
18:19:30bertrikRDS is locked to 3 times the stereo pilot
18:20:26pamaurywhat the stereo pilot ?
18:20:32pamaury*what is
18:21:37 Join kadoban [0] (~kadoban@ip98-165-177-158.ph.ph.cox.net)
18:28:49pamauryMy fear is that the STFM basically just locks on the FM frequency you select and gives you the raw output and you have to manually decode everything (L+R, L-R, stereo pilot, RDS). Which means that just feeding the dac with the dri output will likely produce noise. But I don't know enough about stereo FM and how this receiver works
18:32:25bertrikthe FM signal (what the ~100 MHz carrier is modulated) with, consists of several "sub-signals". The L+R (mono) component is at 0-15 kHz. To get stereo, there is a pilot at 19 kHz and an L-R signal at 38 kHz. RDS is at 57 kHz (3x pilot freq).
18:32:53bertrikBut yes, it looks like a lot of software intervention is needed to get usable output.
18:34:20pamauryif you "just" want to get L+R, you at least need to implement a low-pass filter
18:39:01bertrikprobably yes...
18:39:55bertrikIt looks like stfm1000_alsa_dma_irq calls stfm1000_decode_block which calls stfm1000_filter_decode which does the actual decoding
18:41:19pamauryyeah, I'm trying to implement something and pastebin it so you can have a try at implementing this filtering
18:41:38bertrikthe raw undecoded data appears to be formatted in frames of 4 16-bit words containing "lpr", "lmr" and "rssi" and some unknown (unused?) quantity
18:42:59pamaurywhat are lpr and lmr ?
18:44:15bertrikI'm trying to figure out :)
18:44:39pamauryok, I let you work on this, I'll try to give you a framework where you "just" need to implement the filter ;)
18:44:41bertrikLeft Plus Right and Left Minus Right, I guess

19:02:05pamauryit's not working, the pcm callback doesn't work apparently, but should be close to something hackable
19:02:53pamauryI must leave now, so good luck
19:08:24bertrikthanks
19:16:56bertrikpamaury, the filter can be very basic at first, just doing L = (LPR + LMR) / 2 and R = (LPR - LMR) / 2 to get basic stereo and we can gradually enhance the filter for better performance (like RSSI-dependent stereo blend/low-pass/soft-mute)
19:17:41bertrikno idea yet how they make it run at 44.1 kHz, the i2s clock seems to run at either 24MHz/4 or 24MHz/5

19:51:58Bagderthat's rockboxdev.sh
19:52:19Bagderbut most probably you can still use the set you built before
19:52:35Bagderyou just need to get the sources off a new server to build rockbox

23:17:55rocktriangleI have a question about contrast that I had difficulty understanding last time I asked.
23:18:13rocktriangleIs it possible to set the contrast to have it go lower than 0?
23:18:57rocktriangleAt night when I use the player, it's quite blinding at the minimal amount so I need it lower however 0 is as low as it could go.

23:27:20gevaertsrocktriangle: I'd expect 0 to mean "as low as the hardware allows"
23:28:08rocktriangleAre you sure it's the hardware?
23:28:15rocktriangleOr a limitation by the firmware?
23:28:21gevaertsCheck the source code
23:28:35rocktriangleSince I'm a amature, could you tell me how?
23:28:38rocktrianglean*
23:30:15rocktriangleI don't understand how it's a limitation of the hardware, surely it can go as low as possible. It's not like I'm asking the hardware to have more rom than it has. If it can change the brightness to a certain range then surely it can go lower.
23:31:08Tornerocktriangle: what player is it?
23:31:11Torneis it an OLED screen?
23:31:17rocktriangleYes
23:31:27Tornebecause those may well not go lower; the driver circuit for them is complicated and probably only operates within a given range
23:31:28rocktriangleclip +
23:31:37gevaertsOf course the hardware can go as low as possible. That's the definition of "as low as possible"
