01:13:42bertrikmaybe you can document them on the wiki
01:14:29alexbobPgevaerts: definitely a clip +. blue-yellow screen, and takes microsd cards.
01:14:36alexbobPgevaerts: oh, and the box says "sansa clip+" on it.
01:14:41alexbobP<_<
01:14:55gevaertsAnd you're definitely using clip+ firmware? Can you install other versions of the OF?
01:15:09bertrikWhat OF version are you using? I'm using V01.02.15
01:15:09alexbobPwhen I installed the clip+ firmware directly it worked, so I'm pretty sure yeah :P
01:15:16alexbobP01.02.15 is installed now
01:15:56alexbobPwith an A at the end
01:16:01alexbobPaccording to the "Info" screen
01:16:20dfktare you in MTP mode, or in MSC?
01:16:44bertrikThis version should also accept a patched 01.02.15 version.
01:17:03bertrikI think you need a recent patcher for it though
01:17:51bertrikor a recent RockboxUtility
01:18:58alexbobPmaybe it's my version of rockboxutility
01:19:01alexbobPI'll download a new one
01:19:53alexbobPyep... I was on rbutil 1.2.7

01:39:19TheSevenbertrik: there seem to be datasheet mismatches all over the clock control regs
01:39:54TheSevenplls affecting each other, clocks being directly derived from a pll, without the usual mux+divider in between, ...
01:41:26TheSevenjudging from some diagmode code, the PLL lock count reg is actually counting *output* clocks, so it can't possibly be only 12 bits if it needs to count 150us at 200mhz
01:42:13*TheSeven wonders why we didn't notice all this way earlier. it's kinda funny to recognize that we apparently know hardly anything about this stable target :)

02:08:23[Saint]AlexP: There's two seperate tags that can tell you that.
02:08:38[Saint]but, not one generic "is playback?" tag, no.
02:08:39AlexPYes, in a big comb ination
02:09:14AlexPWhich means I end up with %?cs<%?mp<%Vd(c)|%Vd(c)|%Vd(c)|%Vd(c)|%Vd(c)|||%Vd(d)|%Vd(d)>|%Vd(c)||%Vd(d)|%Vd(c)>

02:18:01pixelmaAlexP: maybe you could "misuse" the %?if tag for it - if you can compare to the current status of %mp (which should return a number)
02:18:23pixelmanote: I just stumbled into the discussion and haven't read too much yet
02:18:39[Saint]though, if readability is an issue, %if won't make anything any easier ;)
02:19:33 Quit Judas_PhD (Quit: This is a quitting message)
02:19:56AlexPpixelma: It isn't a massive issue - I want to display one set of viewports if radio is playing (or paused), another if file is playing (or paused). %cs makes this easy in wps or fms, but in menus I need to also check %mp
02:21:07pixelmashould be shorter at least - if I see correctly it's only a different viewport on one condition of %mp so it's just one comparison and for true %Vd(d), else %Vd(c)
02:21:21[Saint]AlexP: did you mean that with the tags the pther way around?
02:21:38keenerdSilly question. Would readability improve if the config was not whitespace sensitive, instead with a manual WS glyph?
02:21:59*pixelma should rather get some sleep
02:22:04keenerd(And newline glyph.)
02:22:11AlexPpixelma: two conditions on %mp, but if if lets yu do > then it'd be shorter, yeah
02:22:19pixelmait does
02:22:20AlexP[Saint]: Not sure what you mean?
02:22:33pixelmaAFAIK, haven't tried it yet though
02:22:52AlexPpixelma: At the moment anyway, there will be another option eventually for wrs
02:27:06[Saint]AlexP: You said "%cs makes this easy in wps or fms, but in menus I need to also check %mp", I'm pretty sure you swapped the position the tags should be in in the sentence.
02:27:54AlexP[Saint]: no, %cs tells you what screen you are in - in the wps or fms I can only be playing audio from disk or radio respectively
02:28:11AlexPIn menus however, it could be iether, so I need %mp to see which it is
02:29:05[Saint]I don't understand why you'd need to use %cs in the .fms or .wps

03:19:29TheSevenhm, there's something funky going on with the PLLs
03:20:40TheSevenmy suspicion is that there is a total of 4 oscillators: a low-accuracy low-frequency on-chip oscillator, an external 32768Hz quartz, and external 1843200Hz quartz and some USB quartz
03:21:10TheSevenapparently there's a per-PLL way to choose between the external and on-chip oscillator or something
03:22:34TheSevenand there seems to be an additional clkcon reg controlling a mux+divider for i2c
03:24:55TheSevenapparently that on-chip oscillator is mainly used to survive switching between the two external oscillators, which seems to be controlled by an external component
03:28:40TheSevenjudging from sampling rate measurements the on-chip oscillator could be running at 768khz

05:37:07TheSevenas soon as I start tampering with the PLLs, I get clicks in the audio output

05:38:37[Saint]iirc bertrik has a Nano2G also...perhaps you can work it out between the two of you.
05:41:28TheSevenhm, maybe switching the HCLK clock source causes a glitch that propagates down to the I2S bus clock and is big enough to upset the codec... but I don't think that's likely

12:38:06TheSevenbattery current reported by ADC when unplugged: 13-14mA, battery current reported by ADC when plugged: 7-8mA, USB current when plugged: ~11mA
12:38:20TheSeveni know it isn't charging, so the plugged ADC value is probably spurious
12:38:39TheSevenAFAIK the charging regulator is a linear regulator
12:38:47TheSevenso I'd say the ADC is off by ~7mA
12:38:56TheSevensecond measurement:
12:39:23TheSevenADC unplugged: 35-36mA, ADC plugged: 7-8mA, USB plugged: 45mA. huh? explanations?

12:45:10TheSevensaves a whopping 2mA!
12:47:10TheSevenhm, no, that was apparently a fluke
12:47:52BuschelTheSeven: yes, LCD voltage reduction was submitted by myself −− it does not only reduce power consumption, it stopped the humming noise of the LCD :)
12:48:27Buschel(which is far more important for myself as I am really sensible to such noise)
12:50:01Buschelbtw, the nano sucks more battery current for me since a while (~20mA, measured by the ADC). Not sure why this is, even using older rockbox-builds does not reduce it back to the ~18mA I've measured before...
12:50:26Buschelall measured when playing back the same file of course
12:50:48liarTheSeven: i don't have the opened-up ipod anymore...
12:51:52BuschelTheSeven/liar: another option to save more than 2mA via white-background is to switch LCD off via using liar's patch ;)
12:52:00TheSevenfunny: locking the hold switch (which I would have though powers off the clickwheel) *increases* current by 0.5mA!
12:52:18TheSevenBuschel: that's what I will try now
12:52:21BuschelTheSeven: btw, the difference between your and my measurements could be caused by this background-effect. I am using a black one ;)
12:52:40TheSeventhis wasn't reproducibly
12:53:09bertrikTheSeven, maybe some pull-up or pull-down resistor on the hold switch drawing current?
12:53:26Buschelwhat wasn't reproducible? the background- or the hold-switch-effect?
12:53:35TheSevenbartrik: that would be way too much, considering that this would also happen if the device is powered off
12:53:40TheSeventhe background one
12:54:34Buschela pitty, this could have solved easily... I have some white-bg WPS as well
12:55:08bertrikI don't see why that would happen when powered off
12:55:18ranmachanI have an experimental patch for AMS, that uses the MMU to write-protect code, and moves interrupt vectors to the alternate high address to trap null-pointer dereferences. I was thinking this could be nice for debug builds
12:57:58TheSevenBuschel, liar: do I understand correctly that you aren't even shutting off power to the lcd in that patch?
12:58:29TheSevenbertrik: the hold switch can be used to wake the device
13:00
13:01:24TheSevenalso, disabling the lcd controller clock gate could further reduce power consumption
13:05:23liariirc currently i just send it into sleep mode. do we know how to shut the power to the lcd off?
13:07:41Buschelwe know how to switch off the power supply, and it seems like TheSeven knows how to switch off the clock gating
13:09:17TheSevenshutting off the power supply increases current by ~20mA. probably still some voltage on data lines to the lcd or something.

14:16:02Buschelnano 2g memory read suffers from non-aligned buffers (-15% for iram, -10% for dram). so, it makes perfect sense to align heaviliy used buffers in iram −− e.g. for codec stuff
14:20:14TheSeventhis is based on several assumptions that i cannot verify, but i have the impression that i can get embios idling at 192MHz down to ~6mA total :)
14:20:16amiconnI think that applies to all SoCs where IRAM is just a bit faster DRAM
14:21:19amiconnSoCs with true SRAM (PP, coldfire, SH) don't need alignment in IRAM (to more than data size, max. 4 byte); it would just waste precious space

16:33:10kugelTheSeven: you need a send_event() call somewhere in the lcd driver
16:33:45TheSevenfor what?
16:34:46kugellet apps code know the lcd is active again (without polling lcd_active())
16:35:06TheSevenwhat kind of event is that?

17:35:17bertrikPff, I don't know how to make the RSSI show up in the sim, there's a #define HAVE_RSSI in the header file of tuner that support it, so #include "tuner.h" should get the HAVE_RSSI definition, but this is not how it works for the simulator.
17:36:37bertrikIt's a tuner chip specific thing so IMO it makes perfect sense to put it in the specific tuner header file.

19:40:19*Buschel just remember one thing...
19:40:57BuschelTheSeven: wasn't the ext clock getting slower when lowering the cpu voltage supply under 0.975 V?
19:42:08*TheSeven thinks it was 0.900V
19:42:33TheSeven0.975V was the lowest stable voltage for 192MHz IIRC
19:43:17Buschelhmmm, should be easy to figure out with a codec that is boosting/unboosting while playback
19:43:33TheSeveni tried that at 0.900 today and it was fine
19:43:52Buschelok, will try so as well
19:44:25TheSeventhis ldo2 problem is driving me nuts
19:44:43TheSeveni'd really like to know what is connected to this one
19:44:51TheSevenmaybe the USB oscillator?
19:45:01TheSevenand what could cause that insane current draw?

20:04:14BuschelTheSeven: do you know how the current consumptions scales with CPU clock on the nano 2g?
20:05:06TheSevena few milliamps... depends on how much time the cpu is active
20:05:36TheSevenforcing it to 100/200MHz increased the average current by 2/4mA
20:06:00BuschelTheSeven: ok, how much can we save when lowering the lower limit to 24 MHz?
20:06:11Buschelso, 24 MHz vs. 48 MHz?
20:06:26TheSevenwe'll get trouble with the APB if we do that, because the tick timer etc. is based on that
20:06:48TheSevenand i don't think it's worth it, as most codec are occasionally boosting at 48mhz
20:07:29Buschelreally? I didn't test mp3 at 48 MHz, but mI would expect it to run w/o boost
20:07:44TheSevenit doesn't
20:07:55TheSevenit needs ~50-60Mhz
20:08:11Buschelyou got the numbers from test_codec?
20:08:14TheSevenon the other hand, embios is always running at 192mhz and needs less current than rockbox, probably because it's in irqwait mode most of the time
20:08:28TheSevenno, from the buffering debug screen and boosting experiments (forcing to 48mhz)
20:08:39Buschelok
20:08:48TheSeventhere were a few tracks that played without glitches, but the pcmbuf never held more than 50KB
20:09:06TheSevenand the UI was very, very sluggish
20:09:56Buschelthe lcd updates might also have taken some cpu as well...
20:09:57TheSeventhat's another reason I wouldn't want to use 24Mhz: the UI will be laggy
20:10:10TheSeveneven if it's idle
20:12:20Buschelok. another question: is there any reason to use a 48/96/192 instead of 50/100/200 scheme?

22:18:45mrkikoHi all!!!
22:19:15mrkikoFinally I'm about to run rockbox again! And now I'm here for a simple question (I know I can read the buyer's guide, but I would like a more personal perspective)
22:19:43mrkikoI would need a device which: - can run rockbox; - has a very long battery; - offers lots of space. Don't mind if it's flash or disk-based.
22:19:57mrkikoWhat do you recommend?
22:20:10TheSevenwhat is "lots of space"? more than 32GB?
22:20:19n1sdefine "long battery" too please
22:20:47mrkikoeven 32 GB can sufficie. Long battery? Long as possible - no particular requirements ...
22:20:57mrkikoI need to use it with speech aniway
22:21:01mrkiko*anyway*
22:21:14mrkikoI'm blind so the display size is not important
22:22:35mrkikoAnd definitely - it would be better for the device to be very resistant to any kind of hostile environment :)

22:22:40n1siaudio m5l and x5l models have very long battery times but I think they are not available in sizes over 30GB
22:23:09mrkikook... I'm taking down the names to analyse them later
22:23:49n1sone of the sansas with SD slot with a 32GB card could work too

22:27:06mrkiko... ok! I'm looking the two specified here, trying to understand differences between m5l and x5l
22:27:37n1sthe main difference is that the x5 has a color display
22:28:11pixelmaand usually a radio
22:28:18mrkikoah ok
22:28:23mrkikothe m5 is out of production right?
22:29:03pixelmaI think both aren't produced anymore
22:29:35 Part lixxus99
22:30:03mrkikoinfact
22:30:09mrkikoand they sai m5 has a color display aniway
22:30:12mrkiko*anyway*
22:30:21pixelmait doesn't

22:30:44pixelmamrkiko: it has a greyscale display, I know as I have one :)
22:31:00TheSevengevaerts: who can fix it?
22:31:13gevaertsZagor or Bagder
22:31:32TheSevenah
22:31:57gammymrkiko: I have an iRiver iHP 120 and an iAudio x5l here and I've been fiddling with both today.
22:32:58gammymrkiko: I uh, also purchased a 2GB Sansa Fuze today on ebay, the plan being to test it (if it isn't a revision 4?) and if it's nice puchase a 16Gb microSD card for it.
22:34:54gammymrkiko: The iRiver is the only one I have extensive experience using. It worked for almost ten years, and I modded it for a 32Gb CF card as well. Unfortunately I blew up the audio output stage some time ago, and now I'm experimenting with the iAudio
22:34:59gammy(which a friend gave me) which has a faulty "secondary" battery (the iAudio annoyingly having two)
22:35:14gammyPhew. A lot of typing and probably off-topic, I thought this was #rockbox-community.
22:37:17pixelmagammy: only the "L" models have two and unfortunately the Iaudio batteries don't seem to be the best ones (saw it with two "normal" X5s in the family and my M5L also lost quite a lot but still has quite nice runtime overall
22:37:32pixelma)
22:38:57gammypixelma: Ah I see. Yeah the one I have was given to me by a friend as it wouldn't start up at all. Disconnected the large battery and it started up. I'd like to know if the iRiver battery is compatible. Then again it could be the charger that's
22:39:01gammyfaulty.

22:40:28gammyI also tried my iRiver CF mod with the iAudio. It can boot up and put me in a menu. but then panics when I try to list files. I assume it's due to the timings on the CF card, but it's a shame since it works so well in the iRiver.
22:40:45CIA-7r28601 build result: All green
22:41:38S_a_i_n_tTheSeven: You should only need FS #8961
22:41:39Zagorgevaerts, TheSeven: it's a network triggered issue. the server gets confused when all clients disconnect during a round.
22:42:21pixelmagammy: my M5 works well with an SSD, guess there are enough small differences though
22:42:28 Part Zagor
22:42:30pixelmato CF I mean
22:42:30TheSevenso it was actually the server that went offline briefly?
22:42:51***Saving seen data "./dancer.seen"
22:43:01liarTheSeven: i see you are changing the cpus voltage when switching the cpu frequency. you could also reduce the memorys voltage while the cpu is running at the lower frequency
22:43:27TheSevenwe could generally reduce the memory's voltage
22:43:37TheSevenbut is its frequency dependent on HCLK?
