10:42:00c0uttag'day there linus
10:43:26c0uttai haven't done any more work since we last spoke
10:43:36c0uttamy pc dies a horrible death :(
10:45:27LinusNouch, what happened
10:46:44c0uttaupdate to xp sp2
10:46:55c0uttaupdate to xp sp1
10:47:16c0uttaincompatible sound driver - sysaudio.sys
10:47:45c0uttaone of the base sys files for xp and took me ages to find out
10:48:19LinusNso it won't boot?
10:48:40c0uttano, not even safe mode
10:49:07c0uttaended up doing a complete reinstall
10:49:40c0uttai bought Ghost so now keep a backup of my latest image on my jbr
10:50:35c0uttahow are you ? have you settled into your new apartment ?
10:54:12LinusNstill full of boxes .-)
10:56:18c0uttawe did 10 moves in 10 years
10:56:40c0uttastill have boxes
10:58:04c0uttajörg and i spoke about including sound into the menu system
10:58:22c0uttabut i notice that quelsaruk (?) is also doing some menu changes
10:58:37c0uttayou offered to review them - correct ?
10:59:44LinusNyup, he's doing a splash()-like menu look
11:00:00LinusNgives a nice "popup" touch to it
11:00:18c0uttaare you going to incorporate into cvs ?
11:00:28LinusNi haven't seen the code yet
11:01:23c0uttaok. i will finish the quickscreens in the next 30 minutes
11:01:33c0uttajust to save you from being accused of breaking them
11:06:23dwihnoLinus: vaken?
11:06:58LinusNsom fan
11:07:09dwihnostabilt :D
11:11:30dwihnoså här är det
11:11:57dwihnovisst kan man greja hur mycket som helst med flaggor i en mp3 bara man inte har sönder nåt? :)
11:12:05dwihnoalltså ta bort CRC-flaggan och ta bort crc-bytes:en
11:12:19dwihnooch justera så att frame 1 börjar på byte 0
11:12:25LinusNdwihno: english please
11:12:38dwihno<−− is lazy today
11:13:04 Join AciD` [0] (
11:13:25LinusNI'm not entirely sure that you can remove the CRC that easily
11:14:00LinusNyou could try to clear the crc flag and remove the two crc bytes
11:14:07dwihnoThat's what I ment :)=
11:14:08LinusNin each frame
11:14:23dwihnoThe audio data isn't affected.
11:14:27dwihnoSo it SHOULD be ok?
11:14:29LinusNbut i'm not sure if that would work
11:14:47dwihnoAs well as "rewinding" the stream to byte 0
11:15:12LinusNthe thing is that i think those two bytes would have been used for audio data if the crc was disabled when encoding
11:15:31dwihnoyes, but if shift the stream two bytes, it should be ok
11:15:35LinusNso the decoded would expect two more bytes of audio data
11:15:50LinusNin each frame
11:16:17dwihnoYou just change the number of bytes as well.
11:16:34LinusNthere is no "number of bytes" field in an mp3 frame
11:16:35dwihnoAs long as the frame headers are kept OK, it should be OK to remove the CRC.
11:16:49LinusNthe crc flag is in the header
11:17:25dwihnothe frame length is in the frame header
11:17:56LinusNthe frame length is calculated from the contents of the header, yes
11:18:06dwihnoSorry, my mind is all messed up.
11:18:25dwihnoMixing the stuff up.
11:18:42LinusNalso, there is a separate crc in each frame
11:19:20dwihnobut removing the flag and the crc bytes, and shifting the audio stream sounds like a go.
11:20:11dwihnoOr am I out in the blue?
11:20:59LinusNthis is how i see it:
11:22:30 Join Nibbler [0] (
11:22:56LinusNa 128kbit/s, 44100Hz frame is always 417 bytes long, with our without CRC
11:23:21LinusNso if you remove the CRC, the frame will be too short
11:23:44dwihnoso it's irreversible?
11:23:49LinusNi guess so
11:23:56LinusNwhy are you asking this, btw?
11:24:03dwihnoLearning :-)
11:24:15dwihnoAnd my Super Duper Mega Cool MP3 thingy ;D
11:24:24LinusNah, that one :-)
11:24:47LinusNwhy would you want to remove the crc?
11:24:53dwihnoWaste of space :)
11:24:58dwihnoAs with ID3V1/2 tags
11:25:01dwihnoand lyrics tags
11:25:05dwihnoand all sorts of junk tags.
11:25:18dwihnoIf I want lyrics, I keep separate .txt files :)
11:25:26dwihnoI think of tags as something evil.
11:25:48dwihnoHow about rewinding a stream to start at byte zero?
11:26:04LinusNwell, the CRC could be seen as a waste of audio quality, since it uses up two bytes that could have been used to store audio data
11:26:23LinusNrewinding a stream?
11:26:35dwihnoYeah, I found out some of my files has a different sync offset
11:26:45dwihno(and I've tripled checked my algo) :)
11:26:50LinusNi don't get it
11:27:16dwihnoIn a perfect world, the first 12 bits of a file should be set, right?
11:27:23dwihno11 bits, I ment
11:28:06dwihnoSo if they aren't, it should be OK to ffw until those 11 bits are occured and "move them" to offset 0
11:28:43LinusNcorrection: ffw to the point where you find a valid frame header
11:29:08dwihnoYes, the frame header would be validated as well
11:29:13dwihnobut you catch my drift?
11:29:33dwihnoAm I validating any kind of specification by doing that?
11:29:46LinusNyou mean violating?
11:29:52dwihnoyes :)
11:29:57LinusNno you aren't
11:30:23LinusNthere is no specification on how to store an mp3 stream in a file
11:34:41dwihnoI will be removing "trash" bytes as well.
11:34:46dwihno(ID3V1 tags, yeah!) :)
11:44:30dwihnoThank you for your time \o/
11:44:56dwihnoThe PIO mode, does that come with a speed increase?

13:19:11c0uttau there linus ?
13:24:39c0uttawhen i hold down f2, press left, release left, release f2
13:24:53c0uttai get 3 events
13:24:59c0uttaf2 left
13:25:05c0uttarelease left
13:25:17c0uttawhy not release f2 on the last event ?
13:26:05LinusNyou should get release, afaik
13:26:45c0uttai've been getting f2 - very bizarre
13:27:07c0uttacode 0x0200
13:27:15c0uttai expected 0x8200
13:28:56LinusNbtw, you should get 4 events, the first event being just F2
13:29:34c0uttatrue - forgot about that one. i was ignoring it
13:30:37c0uttaanyway, it must have been my error. i used splash() to display the keycode and maybe the delay was an issue
13:30:39LinusNi just tried it myself and i got the release event
13:31:52c0uttai have restored the quickscreen functionality - wnat me to submit a new patch to the tracker ?
13:32:04LinusNyes, please
13:32:13c0uttagive me 5
13:32:37LinusNbtw, remember to take BUTTON_REPEAT into account
13:34:44c0uttai don't believe the current quickscreens take repeats into account
13:35:25c0uttaa more complete solution tho..
13:35:59c0uttamay have to wait until tomorrow for the patch - 23:06 here.
13:36:26c0uttai have another partition resize and ghost image to create yet tonight

23:00:42Guestit was working fine in the morning, so turn it on in the afternoon and there it comes

23:01:41Guestyes it did, let me tell u the exact message, one sec

23:04:13LinusNdoes the drive spin up?

23:04:33Guestyeah kind of, then it clicks...clicks some more, and I get one of those messages
23:04:53LinusNok, then my guess is either:
23:05:03LinusN1) You have a dead (broken) battery
23:05:17LinusN2) You have a broken solder joint inside the device
23:05:25LinusNwhich model?
23:05:32Guestthe 20 GB model
23:05:47Guestcan the HD break like this: when shutting down I accidentaly shook it?
23:05:52LinusNRecorder? FM Recorder? V2 recorder?
23:06:12Guestold school :D
23:06:23LinusNyes it can break, but i doubt it is that in this case
23:06:38LinusNdid you drop it?
23:06:46Guestit was in my school bag the entire time
23:06:57LinusNok, first of all, try to recharge the batteries
23:07:04LinusNthat *may* help
23:07:06Guestyup, that's what I'm doing now
23:07:13LinusNsecondly, replace the batteries

23:11:21[IDC]DragonOK (just testing Jens' code)
23:11:58[IDC]Dragonhis ATA loop is slower :(
23:13:01LinusNok here's the deal:
23:13:38LinusNthe DIOR and DIOW signals are strobes
23:14:17LinusNfor one read access, DIOR goes low once to start the access, and once to terminate it
23:14:59[IDC]Dragon2 time low for one access?
23:16:47LinusNthe cycle time is actually the time between the two rising edges of DIOR
23:17:00LinusNand the hardware doesn't solve this for us
23:18:18[IDC]Dragonso where do the 2 pulses come from?
23:19:56scunnersrry to be a pain, but before i try to flash the rom, do i copy the ajz file from the v2 folder over the daily build ajz?
23:20:01LinusNthat is the ATA specification
23:20:21LinusNscunner: at least run it by playing the ajz file
23:20:41LinusNscunner: easiest way of installing:
23:20:53LinusNunzip the entire zip file to the root of the jukebox
23:20:58LinusNand then reboot
23:21:52scunnerdid that and i have rockbox on the unit, but can i flash the rom for faster boot time?
23:22:22LinusNyes you can
23:22:57LinusN[IDC]Dragon: the ata spec says that there has to be two pulses
23:23:33[IDC]DragonOK, understood, but what incident does normally do that job?
23:24:17LinusNwell, i'm still trying to figure out why it works so well for us...
23:24:22scunnerok, i have the files necessary for that, but there's another ajz file in the flash rom folder that i downloaded plus firmware v2 and no rom ect.
23:24:48[IDC]Dragonscunner: use only the .bin files from that
23:27:03[IDC]DragonLinusN: I think it's not 2 pulses, it's one active high pulse
23:27:46[IDC]Dragonuh, no, the label indicates low active
23:28:16LinusNso, the question is: how does it work so well for us today?
23:29:08[IDC]Dragona good one, yes
23:29:23[IDC]Dragon2 pulses are crazy
23:29:47*LinusN is studying the schematics
23:30:49[IDC]Dragonwhat's disturbung me with the ATA spec: t2 is called pulse width, t2i is called recovery time
23:31:03 Quit Guest ("Leaving")
23:31:15[IDC]Dragonand for t2 it says 8-bit
23:31:54scunneryaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaahoooooooooooooooooooooooooooooooooooo! thank's guys! donation on the way!
23:32:34LinusN[IDC]Dragon: yeah, that's also puzzling me
23:33:06scunnerwow that's fast!
23:33:33LinusN[IDC]Dragon: you are probably reading the wrong timing diagram
23:34:02 Quit scunner ()
23:34:03LinusNfigure 44 is the correct one for data transfer
23:34:14[IDC]Dragonah, yes, it wasn't data
23:34:21amiconn[IDC] Dragon, Linus: There are no 2 pulses, one PIO data cycle consists of one one high and one low period of DIOR/DIOW.
23:34:35LinusNhi jens
23:34:53[IDC]Dragonah, _this_ is Jens
23:35:01[IDC]Dragondidn't know
23:35:45amiconnYes, I'm Jens. Sorry logged on but didn't watch earlier.
23:36:05LinusNok, i guess you can interpret the timing diagram like that
23:37:16[IDC]Dragonthen possibly we violate the recovery time when reading so fast
23:37:18LinusNstill, the /DIOR and the /RD timings don't match
23:37:33 Quit hardeep ("My damn controlling terminal disappeared!")
23:38:14[IDC]Dragonthe recovery starts after /IORDY is de-asserted
23:39:01amiconnLinusN: I think we are talking about the timing diagram at p. 292 of the ATA specs.
23:39:59LinusNi wonder where it samples the address?
23:40:45[IDC]Dragonat the rise of DIOR/W?
23:40:51amiconnAs far as I understand the read cycle goes as follows:
23:40:52LinusNi would guess at the rising edge of DIOR
23:42:00amiconn1. The host selects the desired device (via Cs0, CS1 and DA0..Da0. After that it has to wait at least t1
23:42:54LinusNand dior/diow has to be low
23:43:43LinusNof course
23:43:58amiconn2. The device then sets DIOR high in order to start a read cyle. It has to wait at least tA and then check IORDY status
23:44:37amiconn.[IDC]Dragon: No, as far as I read correctly, a read cycle is started by L->H transition of DIOR.
23:44:41LinusNbut the idle state of dior is high, as far as i know
23:45:03LinusNand they call it a "strobe" in the specs
23:45:25amiconnLinusN: If the devices is not selected, the state of DIOR (and DIOW) doesn't matter.
23:47:36[IDC]DragonI'm not sure about the schematics, but I think /DIOR and /DIOW are connected to /RD and /WR, which are low active
23:48:02[IDC]Dragonso, their idle state is high
23:48:30LinusNthey are
23:49:37LinusNso, the HD expects two rising edges on DIOR
23:50:27[IDC]Dragonno, a rise edge to sample the address and a fall edge to sample the data
23:50:59[IDC]Dragonwithout looking, I'd assume our bus cycle would do the opposite
23:52:06[IDC]Dragonso maybe it works because of a side effect, neighbouring transfers on the bus
23:52:17LinusNmy guess too
23:52:55LinusNi'll try to hook up a logic analyzer to it next week
23:53:26[IDC]Dragonthat'll be interesting...
23:54:04LinusNas far as i can see in the schematics, the RD and WR signals are delayed a few ns, but nothing else
23:55:03[IDC]Dragondelayed by what? is there a buffer?
23:55:30LinusNit has to be delayed, since the data goes through a buffer
23:55:51[IDC]Dragonah, found it
23:56:43amiconnLinusN: You are right, the recorder schematics don't show DIOR and DIOW but /DIOR and /DIOW
23:56:44LinusNfunny way of delaying, btw, seems like they delay the falling edge more than the rising
23:57:07LinusNamiconn: the ata specs call them DIOR- and DIOW-
23:57:12amiconnThis puzzles me, why they would describe the signals and then have the physical signals negated?
23:57:41LinusNthey don't
23:58:18LinusNthe ata spec describes dior- and diow- as strobes
