#rockbox log for 2012-12-09

00:00:21gevaertsThere's almost never a good reason to PM people for technical matters
00:03:01DmLGood to know, thank you.
00:04:28saratogaif its just some problem in the emulator, you're probably on your own since no one has worked on it in ages
00:04:38saratogai guess you could try it in the sim and see if it works there
00:04:48DmLthe fuze+ sim?
00:05:14***Saving seen data "./dancer.seen"
00:06:05saratogaor any sim
00:06:37DmLI'll try that first before posting about it then. I've been wanting to get the development environments setup anyway. I suppose this is as good a reason as any. I do have some coding experience but haven't really had time to look into rockbox dev. And since Lua became an option I didn't think I would worry about the compile process at all.

00:07:43DmLBut in future, would a forum post or flyspray post be better for this sort of thing, do you think?
00:09:57saratogadidn't you say you already posted one?

00:18:23DmLI have previously, but not about this issue. Those other issues were never viewed or addressed.
00:18:39DmLWhich is why i wondered if that was the apporpriate place for it.
00:22:38DmLAlright then, thanks. I'll take a look at the simulator. Thanks for your help Saratoga, and all your various replies on the forums!

00:55:27dfktsaratoga, is there a difference in audio quality between the already committed hermite resampler and the new one without the real audio code?
00:56:09saratogadfkt: no they're equivilent, just i didn't want to use their code so i wrote a different but mathematically equal version
00:56:13saratogahowever, i don't think i ever committed it
00:57:05dfktc231 is commited, c304 isn't, as i understand it?
00:57:45dfktor "merged" as gerrit calls it
01:02:03saratogai think i screwed up the gerrit thing because i can't figure out how to use it
01:02:55dfktheh, i see

01:39:35saratogawhich one were you trying?
01:39:45dfktthe older one, patch set 7
01:40:01dfkti read in the comments that the new one has issues?

01:43:01saratogaah ok
01:44:09dfktthat's where it says "merged" in the box, what i meant before.. which obviously doesn't mean committed
01:44:45saratogano it does, but i think i committed by accident and then reverted it
01:45:12dfktcause the patch applied flawlessly on my source

05:26:52wagnerfcan you tell me are there several read_line functions ?
05:27:08wagnerfI see one named fast_readline
05:30:55JdGordonthey work slightly differently
05:31:41JdGordonfast_readline will be faster because it does much bigger reads from the disk and calls a callback for each \n it finds, regular read_line does 1 byte reads untill it finds a \n and returns which will be super slow on some targets
05:31:57JdGordondepends if the disk driver caches secotrs (which i dont think any do)
05:32:07JdGordonso fast_readline is always preferable
05:33:35wagnerfok i'll take a look at both

21:17:27pamaurybertrik: is this about checking whether the fm tuner has int connected to the cpu ?
21:18:26pamauryyou should monitor all pins because on the fuze+ it was connected to a pin of the cpu but unused by the OF oO
21:20:42bertrikit looks like most GPIO pins are input already (I guess that's the default) on as3525
21:21:26bertrikI think the clip+ OF doesn't use interrupts either
21:23:49bertrikrmmh: here's the patch:
21:24:30bertriktry to see if any GPIO value changes in the I/O ports debug menu, when you switch the radio 'force mono' on and off
21:26:12bertrikpamaury: I think I did see the fuzev2 OF reading GPIO A4 but I didn't understand why. Perhaps it was to check if this pin is connected to the tuner interrupt.

21:27:03pamauryit wouldn't be the first mysterious I/O pin which purpose is unknown :-/
21:27:59bertrikand I sometimes suspect bugs in the OF, like for the clip+, the OF display init code messes with one of the FM I2C pins

21:41:07rmmh(for improved station detection)
21:42:41rmmhI don't understand your patch −− that seems to be for the RDA5802?

21:43:56bertrikoh, sorry
21:44:07bertrikcan you make the same changes to the si4700 driver?
21:44:29bertrikI think GPIO2 from the tuner is connected to GPIO A4 from the SOC
21:47:33rmmhfrom looking at the PCB?
21:47:44bertrikIf that's the case, just enabling HAVE_RDS_CAP should be all that's needed for RDS to work on the clip+.
21:48:00bertrikbut the dual-tuner thing might complicate things a bit
21:48:01rmmhI tried that and it definitely didn't work
21:48:32bertrikno, I didn't look at the PCB yet
21:49:51bertrikrmmh: have you looked at the diagnostic mode of the original firmware yet?
21:50:10rmmhno, how do I do that?
21:50:52bertrikdo you have an OF .bin file?
21:51:19bertrikGPIO2 of the tuner is connected to *something* in
21:52:05rmmhwhich chip is the tuner? the one labeled "0219 CKQW 927"?
21:53:26CtcpIgnored 1 channel CTCP requests in 0 seconds at the last flood
21:53:26*bertrik tries to edit the image to point it out :)
21:56:55rmmhokay, this just makes the tuner turn off when I force mono: si4700_write_masked(SYSCONFIG1, (2 + value) << 2, 0x3F);
21:57:30bertrikeven GPIO1 seems to be connected, but perhaps only for selecting the tuner bus mode
21:58:30rmmhwhat does GPIO dir do?

22:06:18rmmhnothing :(
22:06:21bertrikthe rda5802 seems to be some kind of clone of the si4702, the register map is different but parts of it are suspiciously similar
22:06:57bertrikdid you try rds, or did you have a look in the I/O debug screen?
22:08:54rmmhlooking at the I/O debug screen while toggling the tuner's GPIO2 high and low

22:12:20rmmh20 E5 00 00 here
22:14:13bertrikdo you have a variant 0 or 1 (under "View HW info") ?
22:15:47bertrikI have variant 0, I think that explains the difference for GPIOB_DIR
22:17:04bertrikI'm pretty sure variants 0 and 1 have different mainboard PCBs, perhaps the image on our wiki doesn't match with your player
22:18:56bertrikyou didn't turn of the fm radio when moving from the radio screen to the debug screen, right?
22:19:59bertrikit would be a shame if sandisk removed the fm interrupt line in variant 1

23:30:19darkoI was the guy who bricked sansa clip back then
23:30:44darkothen wrote a history of successfull unbricking with opening and unsoldering battery...
23:30:58darkonow I have iriver H10 6GB and 5GB
23:31:08darkoboth succesfully rockboxed
23:31:13darkoawsome players
23:31:22darkobut with this 6GB version I have a problem
23:31:35darkowhen I power it ON it reports low battery
23:31:57darkobut it powers ON with AC Adapter and when I remove it it stays ON for hours playing music
23:32:07darkoany idea what is wrong?
23:32:28darkoas if player wrongly registers empty battery which is fully charged in fact
23:32:48AlexPIt is probably failing - the internal resistance rises so it is struggling to supply the current needed to spin up the disk
23:33:07AlexPWhen it is already playing the music is buffered from memory, which it can cope with
23:33:12darkobut battery is working for 5+ hours after immediate ac adpater removal
23:33:24darkobuffer is only like 27 MB ?
23:33:25AlexPIt is probably doing other things on startup too
23:33:32darkoi play several gigs of WAV files?
23:33:40AlexPAnyway, it is likely to be a failing battery
23:33:49AlexPNot unsurprising after this amount of time
23:33:56AlexPReplace it
23:34:00darko5GB model)
23:34:12darkobut butteries are OK
23:34:16darkotested in another iriver
23:34:25stripwaxand that one didn't say 'low battery' ?
23:34:36darkonope, that iriver boots fine
23:34:42darkowith all 4 of them
23:34:52darkoall batteries hold 4-6 hours of WAV layback
23:34:55AlexPand another battery in the one that says low battery?
23:35:24AlexPAnd what are the other players?
23:35:29darkonope, neither of 4 batteries are enough for the 6GB model
23:35:45darkoit must be "booted" only with AC adapter
23:35:50stripwaxdoes the 6gb model use a different capacity battery perhaps?
23:35:54AlexPI wouldn't be surprised if this one is trying to draw a bit more current which drops the voltage just under whatever level triggers the warning
23:36:09darkoahh, you are probably right!
23:36:21darkothe player is otherwise just perfect
23:36:33darkoworking fine, long life afterwards etc

23:37:05darkoabout capacity, nope I received it with 820mAh standard ones
23:38:06darkothanks Alex for help
23:38:16darkoat least you got me in right direction
23:38:17AlexPWell I'm only guessing :)
23:38:39darkojust could I modify rockbox firmware to just continue with booting without battery check?
23:38:57gevaertsYou could
23:39:17darkobut that might be unsafe when battery gets drained after 4-6 hours, just loud thinking
23:39:23darkodo you know how?
23:39:29gevaertsYes, that's the main issue
23:39:40darkohi gevaerts
23:39:47darkolong time no see :)
23:40:16darkoso I am stuck then... ok will live with that

23:48:31AlexPSo doesn't boot at all?
23:48:44darkoit boots, but only with AC adpater attached
23:49:01darkowhen thats done the next second you can disconnet adapter

23:52:25darkomaybe but this is old player :)
23:52:44darkoeverything does work fine, just this minor annoyance
23:52:55AlexPUSB seems to be generally buggered on so many players these days I lose track of which are supposed to be working :)
23:53:10darkoI have another h10 5GB as a reference, it works 100% perfect
23:54:06darkoI also replaced a hard drive inside this 6GB, the player is very good for repair, very clean, simple inside
23:54:40darkoalso have a third one
23:54:49darkobut that one has issues with the board
23:55:17darkovolume at -20 dB gives almost perfectly balanced sound on both channels
23:55:25darkobut as soon I lower it or boost it
23:55:32darkoI get balance efffect
23:55:40darkoalso some thiny noise in background
23:57:00darkohmmm does anyone knows with what program to read .mi4 firmware?
