01:48:20casainhohello again :-)
01:48:59casainhocan someon tell me if load_firmware() first clears the buffer to where it will put the data?
01:49:55kadobanhas anyone used tools/release/ recently? it seems to just be doing a dry-run and i can't tell why (if I turn on verbose it prints the messages saying that it's doing the right things, but nothing actually happens and it's going /way/ too quickly for it to be doing the actual builds)
01:50:08JdGordoncasainho: why does it make a difference?
01:50:46casainhoJdGordon: because I am always having bad checksums....
01:50:55casainhoand with random values...
01:51:07JdGordonare you sure you are reading the data from the disk correctly?
01:51:17JdGordonthats what was happening with the sansa v2's
01:51:33casainhoyes, because I implemensted the CRC16 check from the SD Card....
01:52:09casainhoso, how did the developers get arround that problem on sansa V2?
01:52:35JdGordonthe problem there was they wernt reading the data from the sd card correctly
01:53:15casainhook, but do you know if they are doing the CRC test?
01:53:26JdGordonthey are
01:53:36casainhobecause I think we can do it or just ignore
01:53:54kadobancasainho: if the CRC is failing, ignoring the problem seems like not the right answer
01:53:54casainhoso, they could know if they were getting it correctly or not, no?
01:54:14casainhokadoban: my CRC is not failing, is correct
01:54:26kadobancasainho: then there's no problem, right? :)

02:06:21 Part toffe82
02:06:37evilnickmotionman95: Hello
02:06:49casainhomy question is, the checksum is just of the size on the firmware size or of all that fixed beffer size?
02:06:56motionman95whoops, mis type...
02:08:09kugelcasainho: the crc is a simple checksum created by scramble. and it does only cover the binary
02:09:00motionman95Hello! Does anyone here have some free time and would help me fix some rockbox code?
02:10:00casainhokugel: linuxstb , I am getting a bad checksum, with random values... but not so random, for example, the first 3 numbers are equal to the original checksum

02:11:02casainhosince I am loading the data from the SD Card and I get a CRC16 from each 512 bytes block, I am verifying it and reading again for each fail,(and I think I am not geting any fail)
02:11:37linuxstbcasainho: As a test, you could try clearing the buffer. The checksum is just a simple sum, so if the first 3 numbers match, that may mean that the data is _almost_ correct, but you are missing some bytes.
02:11:59casainhoyes, is like that!!!
02:12:47casainhobut I don't know where I am missing it... I just know that the piece of memory where I am putting the buffer is not cleared... at least I am not doing it anywhere
02:13:14kugelcasainho: what's your buffer size?
02:13:20linuxstbThe checksum is only calculated on the bytes read from the SD card - not the spare space at the end of the buffer.

10:13:59B4gderthen read the front page
10:14:19ReconMarineI have a generic MP3 MP4 player from Orbit The ThunderX
10:14:29B4gderthere's no such thing as a "generic" player
10:14:49B4gderif the model isn't explicitly mentioned on the front page as supported, it isn't
10:15:38B4gderI've never even heard of that player before...
10:15:59ReconMarineI guess that prevents you from answering the questions then doesn't it
10:16:07B4gderno it doesn't
10:16:35ReconMarineIt looks like an Ipod Nano, the tall skinny one with the round dial in the center

10:19:41B4gderask in forums for that player
10:20:00ZagorReconMarine: we know because we write the software. and we haven't written any for that player.
10:20:08B4gderand NO players are working until we make SPECIFIC support for them

10:20:22B4gderand since we haven't for this, we KNOW rockbox doesn't work on it
10:20:52B4gderbut it probably be made to
10:20:56B4gdergiven enough effort and time
10:21:10Zagorthese are not generic pc-type machines. every single player has different hardware and needs custom code to be written.
10:22:17ReconMarine that is the company, never heard of it? and this is the specific player
10:22:24scorcheif you still dont believe us, feel free to try to install rockbox ;)
10:23:14ReconMarinehow about I keep asking relevent questions, instead of playing the part of an idiot and just "installing" the software there scorche
10:23:24*B4gder bets on one of the chinese hw setups
10:23:35scorchenot only do we have to program specifically for each individual piece of hardware in the device, but we have to figure out how to get our code to run as well..
10:24:00ZagorReconMarine: there are hundreds of different brands of players on the market. we tend to focus on the big names since they have a somewhat larger user base.
10:24:25B4gderand simply the ones devs care about
10:24:41B4gderstart working on this and we'
10:24:45B4gderll start caring ;-)

10:57:13Jaykayis there any commit in the last 500 ones that could increase battery runtime >1h? or is it normal that many commits do their part for a longer runtime?

11:02:04Jaykayi guess fining out of the reason is not worth the effort
11:02:25B4gdernot when the direction is fine methinks
11:04:22Jaykaybtw if someone has a idea how i could do a helpful battery bench (with some settings, codecs etc) just write me....
11:06:52***Saving seen data "./dancer.seen"
11:08:07Jaykaymaybe you could write the idea, maybe also in a way that helps me :)
11:09:28BigBambiSorry, you said just write me
11:09:39BigBambiJaykay: Generally you want to compare to the OF
11:10:02BigBambiJaykay: So that means chosing settings that are available in both, and generally turning everything off
11:10:20BigBambiThen you want to pick a codec that is playable in both
11:10:57BigBambiThen pick a playlist that is bigger than the music buffer, put it on repeat and wait :)
11:11:04*JdGordon thinks rasher to get to work on a distributed runtime bencher for every build...
11:11:23Jaykayoh yes that would be nice ;)
11:12:05Jaykayis there a nice way to find out the runtime of the OF? except connecting it with a microphone of a computer
11:12:10BigBambiI like to connect the output to a recorder so that I have a good record on both OF and rockbox exactly when the music output stopped
11:12:18BigBambiJaykay: That is the best way
11:12:29BigBambiJaykay: Otherwise you will end up having to stare at the player
11:12:44BigBambiAlso, if yoy record both in the same way, then you have the same load on both
11:13:42Jaykaynot a comfortable solution...
11:14:03Jaykaybut maybe illl try next time..

11:17:12bluefoxxso with the coming release [or planned release at least] of 'sdxc', will rockbox adapt to provide support for those cards as well, on applicable players?
11:18:00B4gdercare to name a few players on which we'd have the option on?
11:18:14B4gdervapor vapor vapor
11:18:48bluefoxxe200 perhaphs?
11:18:55bluefoxxsince rockbox does sdhc on them
11:19:17bluefoxxit would definately extend the life of the player a fair bit
11:19:29B4gderwell, when the spec comes and the card comes and they can in fact be bought by mortals, then we'll see
11:19:35kadobanis sdxc even a spec. yet? seems a little early...
11:19:45B4gdera _little_ yes
11:19:53B4gderit's little more than just words right now
11:20:10kadoban"pending release"
11:20:34B4gderyes, the spec
11:20:54bluefoxxjust me being curious as to if i will have to buy a new player if i want more than ~38 gigs of storage on a rockboxed player
11:21:06B4gderbluefoxx: but how can anyone tell?
11:21:20B4gderis your 32GB usd already full?
11:21:31bluefoxxno, but my 6 gig player and 8 gig card are
11:22:09bluefoxxand i could easily fill an additional 18 given chance

12:14:44gevaertsThey should be worked on until ready to commit, and then committed

21:04:35Toni1Hi there
21:05:07Toni1Anyone against committing the latest patch in FS #8663?
21:05:36 Quit tessarakt ("Client exiting")
21:06:03Toni1I hope, it will solve the '2bytes inserted' bug on the Sansa e200 and c200.
21:06:18*gevaerts is not against :)
21:07:03***Saving seen data "./dancer.seen"
21:07:03gevaertsdesowin_: do you still have your sansa and your printer?
21:08:00kugelToni1: No, commit please!
21:08:17kugelI've been using USB etc since the first stable patch, no problems at all
21:08:17Toni1gevaerts, do you think usb can enabled, if the writing is bugfree then?
21:08:31kugel(I know this isn't a quite USB issue)
21:08:50kugelToni1: I think there's still this resetting problem
21:08:57Toni1kugel, you have also an e200, right?
21:09:01gevaertsToni1: maybe as a setting. USB is still pretty much unusable on some setups
21:09:57kugelthe problem is imo, that even if file transfer is working, we cannot say USB is working.
21:10:31kugelsince there's still this resetting problem (which doesn't seem to cause corruption though), and that people with HUBs tend to have instable connections
21:10:35kugelcorrect me if I'm wrong
21:10:46*gevaerts corrects kugel :)
21:10:58pixelmait was pretty much unusable on my PC's USB front ports
21:11:19pixelmalast time I tried, need to update myself on this ;)
21:11:22gevaertskugel: it can cause corruption in extreme cases, as it can basically throw the sansa off the bus, which is equivalent to unplugging unsafely
21:11:54kugelhm, then linux handled it goodly when I had the 5 resets during transfering the 3.2GB image
21:12:03kugelas you already said, I was lucky
21:12:15kugelgoodly=well, no?
21:12:59gevaertskugel: if you get a few resets now and then, it won't throw it off the bus, but on some setups even basic enumeration is hit and miss. On those, anything can happen
21:13:22Toni1gevaerts, any idea what causes the resets?
21:13:33desowin_gevaerts: yes, and you're lucky enough, i'm home!
21:13:46kugelToni1: btw, I had 3.3+ MB/s (without serialize_writes, using the patch I uploaded), not any slower than the OF
21:14:01gevaertsdesowin_: great! If your setup survives with Toni1's patch, *any* setup will survive :)
21:14:08kugelok, I didn't messure it exactly, but 1 song/s is what I get using the OF too
21:14:30Toni1kugel, I am far from OF performance. Still I would like to get rid of the of.
21:14:41kugelso i do
21:15:06kugelyour patch works on my pc as well as on my notebook, I'm ready to wipe the OF
21:15:14gevaertsToni1: there has been a lot of speculation. It's almost certainly some portalplayer initialisation issue as the gigabeat S with the same controller on a different SoC works perfectly. Whether that means RAM setup, cache issue or clocking is much less clear
21:15:29kugelI already wiped the OFs bootloader many month ago (so I've basically only the system folder)
21:15:53desowin_ sd_write_sectors_diff_v2.diff - this one?
21:16:18Toni1desowin, yes
21:17:12kugelcommit commit commit :)
21:17:27*gevaerts still doesn't understand at all how this printer could make a difference
21:17:28Toni1ok,ok, I feel encouraged :)
21:17:43desowin_gevaerts: believe me, it does
21:17:55pixelmait would also need to pass amiconn's hub test ;)
21:18:09gevaertsdesowin_: I do believe it, but since I don't understand it it's purely faith :)

21:52:46gevaertskugel: SERIALIZE_WRITES can probably go soon, but usb is very different from iap in that we don't need testing to know that it's buggy
21:53:31kugelwell, but it would surely be intersting in how big the percentage of problematic setups is
21:53:32desowin_there aren't bug-free things anyway ;)
21:54:12gevaertskugel: not really. *all* setups are problematic, some are just less so than others
21:54:46kugelcould it be related to boosting? is rockbox boosting while in usb?

22:00:52bertrikthe LPC2148 microcontroller that I worked with, needs to run at least at 18 MHz in order for it to communicate properly with the built-in USB controller, it has something to do with the two clock domains (processor vs. USB peripheral clock). Perhaps PP has a similar problem.

23:32:23casainhoyes, to file.c and fat.c
23:32:52gevaertsIf you want examples of how to write a file, you need to look at places where files are written
23:34:02casainhocan you give an example? I am used to llok at bootloader files... but there is no need to write on bootloader
23:34:49gevaertsAnywhere. recording, playlists, settings, file browser,... There are lots of places in rockbox that write files...
23:35:05rasherMany plugins as well

23:37:56casainhook, thanks −− I am looking now to settings.c
23:38:57casainhoI have one question about pointers
23:39:04casainhofor example here:
23:39:05casainhostatic bool write_nvram_data(char* buf, int max_len)
23:39:29casainhochar* buf means that *buf is a pointer?
23:39:56casainhoI don't understand why char if address is a 32 bits value... ?

23:40:45gevaertscasainho: this channel really isn't for absolute beginner C questions
23:41:11casainhogevaerts: okok
