00:51:35casainhopamaury: what that means? why is there a Brekpoint instrautcion?
00:51:51casainhopamaury: are you doing debug?
00:52:12pamauryno, I just find it weird that the fimware code has some breakpoint instructions in it
00:52:35casainhowhat firmware is that?
00:52:39pamauryfuze+
00:52:58CIA-7r28728 build result: 5 errors, 43831 warnings (kugel committed)
00:53:38casainhooriginal firmware?
00:53:47pamauryyes
00:54:03casainhoit's easy to access OF?
00:54:11casainhohow did you got it?
00:54:37casainhohaving break point instructions is very weird!
00:55:07pamauryyou can easily download the firmware and I spent quite a number of hours figuring out the format and encryption scheme with bertrik
00:55:15pamaurythe tool is in svn
00:56:26CIA-7New commit by 03kugel (r28729): Fix red by moving the difinition up.

00:58:01casainhoah, ok! :-)
00:58:25casainhomaybe format/encrytipon schme is worng ;-)
00:59:01CIA-7r28729 build result: 723 errors, 62215 warnings (kugel committed)
00:59:05casainhomsut be worng... I mean, there should no be breakpoint instructions, or the fimrware would not run,, right?
00:59:57pamaurythese are conditional
01:00
01:00:11pamauryI guess there are a cheap & low-level panic :)
01:00:21pamauryI assure you the format is right :)
01:00:42kugelperhaps they distributed a debug built, would also explain the zero key
01:01:33pamaurypossibly, that would explain some strange conditions in the code which seriously look like assertions
01:02:10casainhowhat SOC does it uses?
01:02:35pamaurystmp37xx == imx23
01:02:40casainhouaua!!!
01:02:51casainhopamaury: I am working also with imx233!
01:03:02 Quit Keripo (Quit: Leaving.)
01:03:16pamauryyes, I know. We weren't talking about imx23 by chance :)
01:03:47casainhohey, I think guys at Chumby don't know how to decrypt image file!! and you got it????
01:04:31pamauryI documented it on the wiki and I wrote the sbinfo tool in svn with bertrik
01:04:34casainhowhere is the tool on SVN?

01:06:11CIA-7New commit by 03kugel (r28730): That was a bit too far upwards :(
01:06:19casainhopamaury: thanks!!!!!
01:06:47pamaurykugel: you particulary good at generated lots of builds errors
01:06:51pamaury*generating
01:07:19casainhopamaury: so, will you create imx23 on Rockbox tree?
01:07:29kugelwell, I checked the sims before the first commit but not a real target. now I checked a real target but not the sims :'(
01:07:36casainhopamaury: do you have any working code?
01:07:36kugelbad luck
01:07:43pamauryhaha
01:07:58pamaurywell, first we need to disassmemble the firmware to figure out the pins
01:08:11pamaurybertrik is working on some part and I'm working on another one
01:08:26kugelI suspect we also don't know yet how to inject some code?
01:08:29pamauryIf we get sufficiently enough information, we'll try to port it I guess
01:08:30CIA-7r28730 build result: All green
01:08:57casainhohere is the code I have for imx233, for Propendous board I am using: http://lyre.svn.sourceforge.net/viewvc/lyre/propendous-imx233_board/firmware/
01:09:10casainhowe got a lot of help from Chumby devs!
01:09:19pamauryNone of us as a real target. It seems there a reset mode which puts a recovery version of the firmware and you can update the firmware by putting the file at the root in MSC mode
01:09:28pamaury*has
01:10:07pamauryIf we are lucky, we can just write the code, convert it to .sb using elftosb2 and update the firmware just like with the OF
01:10:08casainhothere is a USB mode recovery
01:10:16pamauryon fuze+ ?

01:10:34casainhoon imx233 there is a USB recovery mode....
01:11:12pamauryI think I read somewhere in the doc that the manufacturer can enable/disable boot modes, so we don't really know if it's enabled and how to trigger it
01:11:56casainhoyes, there are fuse bits, that manufacture can burn
01:12:23casainhothere is a windows application to communicate by USB with imx233 and we can see/configure that bits
01:12:31pamauryyeah, and we saw that they did a nice job at keeping the zero key ;)
01:13:02casainhoyeah... that's de default key of imx233... so maybe they are not changing nothing on the fuse bits...
01:13:05 Quit n1s (Quit: Lämnar)
01:13:18pamauryThere might be some difference between imx233 which is a board and imx23 which is on the fuze+
01:13:36casainhohmmm, ok
01:13:48kugelI think they regretted the USB recovery on the e200 (it made more trouble than it helped) and the non-existent usb recovery on the ams series worked pretty well so I assume they deactivated it again
01:14:03 Quit Stummi (Ping timeout: 260 seconds)
01:14:15pamaurywhy more trouble ?
01:14:20casainhohey, there is only imx233!

01:15:53JdGordon|kugel: I've had no rockbox time for ages, you don't want to take over the open() patch do you?
01:15:55pamaurywhen it comes to the chip, I think there is one which is imx23=imx233=stmp37xx, you can call it the way you want
01:17:55kugelJdGordon|: I can have a look...maybe
01:18:12pamaurykugel: actually, someone on the forum and on irc (if iirc) told us he tried the "reset function" (hold on/off for 20 seconds) and he said it acted like a firmware upgrade. So maybe there is a kind of recovery function
01:18:31JdGordon|kugel: I'd also ask about the dynamic screen size one but IIRC you wernt particularly keen on it?
01:18:42 Quit robin0800 (Remote host closed the connection)
01:19:56kugelI'm not overly keen on it because it doesn't really solve any problems because themes and many plugins are still resolution dependend, but I'm be in favor in generally

01:21:05 Join Keripo [0] (~Keripo@dhcp0101.kin.resnet.group.upenn.edu)
01:21:56kugelI thought the other day that we could possibly have themes resolution independent if we let %V (and friends) take % (e.g. x=10% of the width) as parameters and have bmp resize for the theme's images
01:22:50casainhopamaury, so you don't have a Sansa Fuze+?
01:23:07pamauryno
01:23:20pamaurynot yet ;)
01:23:20JdGordon|kugel: I dont tinhk that would solve it all that much
01:23:38JdGordon|and that is ony a bit scary
01:32:18casainhopamaury: so, what is your motivation?
01:32:48pamaurymake sure the fuze+ arise
01:33:12pamauryI just don't want to buy a fuze+ if I'm not sure we can port it
01:33:24pamauryAnd that wasn't clear until we decrypted the sb format
01:33:34pamaurys/until/before
01:34:51casainhod oyou know how many FLASH chips fuze+ have inside?
01:35:05pamaurythe wiki as some photos on the fuze+
01:35:08pamaury*has
01:35:11casainhowhere is stored firmware + user files?
01:35:11pamaury*of
01:35:36pamauryit is probably stored in a nand memory

12:20:54sampattuzziHello people of rockbox. I'm trying to debug some USB issues which I reckon are due to rockbox not handleing I/O errors correctly. Could somebody point me to the correct section of the usb stack and possibly relevant documentation for the USB spec?

12:27:46gevaertssampattuzzi: You're probably looking for SCSI specs here
12:28:06gevaertsAnd in the rockbox code, firmware/usbstack/usb_storage.c
12:28:38sampattuzzigevaerts, cool, I will take a look at that, see if it makes any sense.
12:28:45gevaertsWhat I would do is start with USB tracing (if you're on linux, wireshark can do that) of both the OF and the rockbox code
12:28:46Torneyou might get more by talking to us about what issues you've got, and why you think there's a problem with our handling
12:29:01gevaertsIf you manage to get such traces, please attach them to your flyspray task :)
12:29:49gevaertsThe main problem is that I've never been able to test these things due to a lack of suitably broken hardware
12:30:15sampattuzzigevaerts, out of interest, I noticed lots of logf() calls in the code but couldn't find a way of enabling them in the documentation.
12:30:47Tornelogf.h sort of explains it ;)
12:31:02gevaertssampattuzzi: enable the "#define LOGF_ENABLE" near the top of the source file, then pick "Advanced" when configure asks, and then enable logf there
12:31:59gevaertsTorne: context is FS #10873

14:14:05amee2khm... did anyone else ever have the idea of porting rockbox to PC style platforms?
14:14:45amee2ki recently got my hands on two really old laptops... a thinkpad that i modded into a serial terminal using linux
14:14:49amee2kand now i've got this old
14:15:31amee2kArmada 1700 here and kinda thought it would make a nice jukebox with rockbox on it
14:16:05amee2ktheres nothing on the wiki at least that suggests there is an x86 port
14:16:36tmztamee2k: there's a simulator
14:16:55gevaertsYou should be able to do something based on the SDL application port
14:17:06amee2kits like a P2 200 in it
14:17:07tmztwhich is a native build using libsdl, assumming you have a framebufer
14:17:25amee2kthe windows 98 on it takes ages to load
14:17:46amee2ki could try install linux on it and see if the simulator works
14:17:54amee2kbut a native port would be like
14:17:58amee2kinfinitely superior
14:18:32gevaertsWell, feel free to work on it
14:18:40n1sit would also take a lot of work whereas compiling the sdl app takes a few minutes tops
14:19:03amee2kgevaerts: yeah... if i ever get the hang of this i might just do it
14:19:36amee2kwhat i'd find kinda ugly about just using the simulator is that you'd end up with the emulation screen on an X display
14:19:41amee2kinstead of a real display
14:20:12amee2kand i'm not sure if i can get any useful performance out of a slow processor like that
14:20:15gevaertsYou can use SDL on a framebuffer
14:20:36amee2khmm...
14:20:43*amee2k ponders
14:22:34amee2kso i'd basically package an embedded linux as bootloader lol

15:07:56amee2kmmmh, i'll first see if i can fix the ipod and play around with the plugin api. if i can't even get that in my thick head, not much point in trying a port >_<
15:10:30Torneporting to native x86 is going to involve a *reasonable* amount of specialist x86 knowledge
15:10:37Torneto implement, say, context switching
15:11:14Tornei don't want to stop you but you may find it easier and more useful to just get the SDL version on an absolutely minimal linux distro
15:11:20gevaertsThe advantage is that such knowledge is reasonably widespread and things are well documented
15:11:26TorneWell, true
15:11:50n1sbut you'd still need to write drivers and stuff
15:11:52Tornea tiny linux distro consisting of basically just a kernel and a copy of rockbox with libsdl compiled to use the framebuffer, though
15:12:03Torneis going to boot in a comparable time to a native rockbox port
15:12:09Tornebut you have to do *way* less to get it running
15:12:30amee2kyeah, what gevaerts said. i don't need to reverse engineer the platform first
15:12:36Torneso, yeah. if you really want to do it, go for it; but x86 is *really weird*
15:12:50Torneeven though the docs exist, you may be underestimating just how weird it is
15:12:53Torne:)
15:12:55amee2kalso, i understand it that rockbox assumes a plain memory model so no need to deal with segmentation or paging
15:12:57gevaertsOf course you *can* reverse engineer it, and only look at documentation when you really get stuck :)
15:13:10Torneamee2k: you can't avoid dealing with segmentation on x86, at least in a minimal way
15:13:23Torneand you would probably want to write a pagetable anyway
15:13:36amee2kTorne: well, yeah. you set up three segments that span the entire available memory and leave it at that
15:13:49amee2ki did some real mode os deving when i was in school, maybe 6 or 7 years ago
15:14:07n1smake it a payload for coreboot and flash to the bios chip!
15:14:08amee2kit was kinda cool, but i didn't get too much into PM stiff
15:14:10Torneyou don't need to do anything *complicated* with the MMU but it's probably nicer to have it enabled and make a fixed virtual memory map
15:14:25Tornewe do that on the ARM platforms we support that have an MMU
15:14:27gevaertsn1s: does coreboot support such old laptops? :)
15:14:41amee2khmmm thats an interresting idea actually
15:14:51amee2kto deal with awkward physical memory mappings
15:15:04n1sgevaerts: it hardly supports anything so you will still have all the fun porting to do :)
15:15:27amee2kiirc, handling the memory stuff kinda was what got me stuck with protected mode stuff back then
15:15:54amee2kwell, i was about to put a multiboot header on the kernel thingy and use grub to load it
15:16:01Tornebut anyway; the advantages I can imagine of running rockbox natively on x86 versus running it under linux is virtually zero
15:16:16amee2kthat'd dump me right into protected mode with at least a half decent memory layout provided
15:16:16Tornefor a sufficiently small linux.
15:16:58amee2khehe
15:17:18amee2kthese days small and linux is sort of a contradiction unless you really want to start a distro from scratch
15:17:28Torneer, why?
15:17:36amee2kfor the serial terminal mod on the thinkpad i tried to fit linux on a 128M flash card
15:17:39amee2kforget it :P
15:17:51Tornei have several working linux systems that fit in 4MB
15:17:58Tornemaybe one or two that fit in 2MB
15:18:14amee2kyeah, but support for them is awkward, and they're usually specialized
15:18:23Torneyou would only need a kernel, busybox to handle boot/init, and rockbox and the libraries it uses (SDL)
15:18:28TorneI'd be surprised if that came to more than 16MB
15:18:29amee2kso you'd effeectively end up forking the distro and modifying it for your stiff
15:18:31amee2kstuff*
15:18:32Torneyou could make it a ramdisk image, even
15:18:56Torneno, this is not using some specialised system
15:18:58Bagderamee2k: for small embedded things you don't need to complicate things and use a "distro"
15:19:01amee2kyeah... thats kinda what i meant by making a distro from scratch
15:19:13TorneYou don't hvae to make it from scratch
15:19:16TorneOE builds it for you
15:19:24amee2k"OE" ?
15:19:24sampattuzzigevaerts, I'm looking at the wireshark traces right now and they appear completely different. OF shows only protocol USB and info URB_BULK whereas rockbox has a lot of USBMS and varied info.
15:19:33Torneopenembedded
15:19:42amee2kdoes that work?
15:19:45Torneof course
15:19:49Tornewhy wouldn't it work?
15:19:51Bagderbuildroot should also be decent
15:19:55amee2ki looked into emdebian but its a pile of wank
15:19:58sampattuzzigevaerts, would you like me send them to you in some format?
15:20:13gevaertssampattuzzi: can you attach them to the bug report?
15:20:16amee2kthey don't even have a precompiled 486 kernel lol
15:20:20Torneno it isn't.
15:20:27Torneand why would you have precompiled kernels for embedded systems?
15:20:29Tornethat would be mad
15:20:33sampattuzzigevaerts, which would be the best file format, they are very long.
15:20:36Torneanyway. this is kinda offtopic.
15:20:48Tornefeel free to try and port to native x86 if you want
15:20:55amee2klol
15:20:55sampattuzzigevaerts, flat text would seem a little inaccessible.
15:21:04Tornebut I seriously think there will be no real benefit over using linux/sdl
15:21:11gevaertssampattuzzi: native wireshark saves, compressed
15:21:15amee2kwell, i'll play around with it on the ipod and see how it goes
15:21:18Torneif you don't know how to make a sufficiently small linux then that's a different problem, unrelated to rockbox :)
15:21:27Tornei can show you, if you ask some other time ;)
15:22:16amee2kthat would be cool so i might just take you up on that sometime
15:22:18amee2k:)
15:23:59 Join evilnick_B [0] (0c140464@rockbox/staff/evilnick)
15:25:13Tornethe interesting and rockbox-relevant part, then, would be getting the RaaA-on-SDL done nicely
15:25:31Torne(rather than running the simulator)
15:25:51Torneyou could develop/debug/test that on a full linux for convenience
15:26:05amee2khehe yeah
15:26:20n1sthe sdl app already works although it's not much different from a touch sim
15:26:33amee2ki've been thinking about a convenient way to update the firmware without the device acting as usb device
15:26:40Tornen1s: yeah, i meant making it "nice"
15:26:50n1sah
15:27:01Tornei.e. keyboard shortcuts, proper filesystem scanning, etc
15:27:07Tornesome of the same issues we have on android, i guess
15:27:08amee2kwell, it should work in full screen mode, obviously
15:27:22amee2kand the configuration menu would probably need some way to configure the keymap
15:27:58Tornefor a PC booting off an intenral hard disk updating the firmware is easy.. just copy it over
15:28:04amee2kthough that can stay in a header file for the first try
15:28:06n1si think RaaA as it is would work *better* for a dedicated system's only UI than it works as a regular desktop app
15:28:13Tornen1s: yes, undoubtedly
15:28:29amee2kTorne: yeah, but you need to get the hard drive out and on a usb adapter
15:28:36amee2kevery time you update it
15:28:54amee2kuntil you got it working enough so you can upload updates via USB
15:29:28n1samee2k: can't you run a shell on your busybox thing to copy stuff via usb?
15:30:09Torneyou wouldn' tneed to do anything to make usb work if it was running the linux kernel
15:30:12amee2ki'm not sure if you can make a USB host controller act as a device end too
15:30:12Torneyou just plug in a usb stick
15:30:16Torneyou can't.
15:30:35amee2kyeah, i kinda expected it won't work
15:31:13amee2ki could make a USB to serial bridge with an avr controller, but the transfer rate would drag ass
15:31:35Torneyah. or if you used linux, then USB host would Just Work and you could use any usb storage device.
15:31:35n1salthough for early phase debugging you probably want to run it in a VM
15:31:39amee2kmost uarts top out at something like 115.2 kbaud
15:31:44Tornealso, you could have networking
15:31:47amee2kand thats a tough call for the AVR too
15:32:02Torneyou could just have a button that ran a script in the host OS which downloaded and installed hte latest build from the internet :)
15:32:08amee2krockbox does support a network stack?
15:32:23Torneno, but it wouldn't need to
15:32:32Tornelinux has one.
15:32:35amee2khmmm
15:32:37Torneand busybox implements wget and friends
15:32:38amee2ki see
15:32:48Torneso you just exit rockbox, run a shell script that downloads a new build and installs it, then run rockbox again
15:32:55Torneyou can automate that esaily :)
15:33:54amee2khmmm i'm kinda starting to like the idea of layering it on a linux kernel
15:34:18Tornethere are lots of advantages. the only real advantage to doing it natively is it *might* boot slightly faster
15:34:32Tornebut we're likely talking a difference measured in a single digit number of seconds here, if that
15:34:54amee2kfunctionality and using existing device drivers are certainly big + points
15:35:26n1sindeed
15:35:32amee2kespecially using the linux VFS layer. i kinda understand rb natively only mounts a single file system at a time
15:35:41Torneno, we support multiple mounts
15:35:52Tornesee devices with both internal storage and an SD slot
15:35:54Tornelike the fuze
15:36:08amee2kthe simulator intercepts the raw file system calls and redirects them to appropriate C library calls, right?
15:36:20Torneyou wouldn' tbe using the simulator
15:36:26Torneyou'd be using the SDL app port
15:36:34Tornethey're similar, but not the same thing
15:37:22n1sso you would use linux filesystem and harddrive functions
15:37:51Torneindeed. rather than simulating a single device filesystem, the port would just have access to the entire host's FS
15:38:00Torneso yeah, it would see whatever was mounted on the linux VFS.
15:38:26Tornethings like mounting USB devices and so on can just be don eby the host, with busybox udev scripts to automount inserted storage devices, etc
15:39:27Torneanyway, if you wanted to do something like this a good start would be experimenting with the sdl port on a regular linux system
15:39:42Tornejust fire it up and try using it and see what works well and what doesn't :)
15:39:59Tornecutting the host linux down to the bare minimum can be done seperately later

17:57:37pamauryI don't know how they choose yet

18:52:25pamauryerror handling in rockbox is a mess
18:52:50n1strue that
18:52:52gevaertsMaybe, but usually it's not because someone did weird things in a spec
18:53:40pamauryah, you mean the protocol error handing :)
18:53:52*gevaerts claims that a bad sector is *not* a protocol error and therefore an endpoint HALT is *not* an appropriate response
18:54:13tmztit's a sense error
18:54:57gevaertsWell no, it returns an error code in the sense data :)
18:55:08tmzterr, yeah
18:55:14tmztbut not in the transport
18:55:16gevaertsBut in USB it also involves stalling the endpoint, which messes everything up
18:56:09pamauryyeah, ums is really different from other usb protocols
18:56:17gevaertshm
18:56:24gevaertsMaybe there's an alternative solution
18:56:38pamauryto what ?
18:56:57gevaertsMy guess is that the stall is there because you send less data than expected, which would otherwise confuse the host
18:57:38gevaertsBut according to my reading of the UMS spec, that stall is optional
18:57:52pamauryI don't have the spec in mind
18:58:29gevaertsSo in theory, we could just send enough data (all zeroes or something, or just random junk) instead
18:58:47gevaertsThe host should know that this data is junk because we still return an error code
18:59:08gevaertsThe problem I have right now is that after a stall the CSW doesn't always get through
18:59:16gevaertsIt sometimes gets eaten by the stall itself
19:00
19:00:35gevaertsAnd that's not at all trivial to fix
19:01:54sampattuzzigevaerts, how does tho OF deal with it?
19:02:29gevaertsBy having a different usbstack design :)

22:32:57*n1s points to Torne
22:33:08pamaurywhat does this mean: MCR p15, 0, R0,c7,c10, 4
22:33:30pamauryI'm not really familliar with the arm internals, appart from basic instructions
22:33:31AlexPBagder: about?
22:33:54Bagderyeps
22:34:01AlexPPM :)
22:34:13Tornepamaury: that's a DSB
22:34:33Torneeverything on c7 is cache control
22:34:44pamaurywhat does DSB mean ?
22:34:50Tornec10, 4 is data sync barrier, or on older arms drain write buffer
22:35:30Torne(on older arms draining the write buffer was sufficient for a DSB)
22:36:05pamauryok thanks, I think I need to find a good doc on this or read the arm manual
22:36:34Torneit's all in teh ARM ARM
22:36:41Tornejust.. read an old version, if you have an old chip
22:36:44Torneit's less confusing that way
22:37:13*Torne recommends DDI0100E for ARM9 and DDI0100I for ARM11
22:37:28Tornethe ARMv7 arm is way harder to follow
22:37:39pamauryit's an arm9
22:37:51Tornerev E is easy to find on the internet, google for that number and pdf
22:37:52Torne:)
22:38:07 Quit stoffel (Remote host closed the connection)
22:38:07Torneand that version is a mere 811 pages, not too uch to take in ;)
22:39:59Torneanyway, you need DSB when you're writing something to ram that you want to be visible outside the core proper, unless the memory is unbuffered
22:40:03n1sor maybe i'm wrong, the install target in root.make does call buildzip with "zip -r0" as an arg but i now realized that someone made make install do target builds too now, right?
22:40:28Torneit's just a writecombining buffer basically, but it's written back lazily so unless you DSB then other bus masters, or the ARM's own MMU, won't see the writes
22:40:34pamauryok thanks
22:40:34Tornewell, aren't guaranteed to see the writes.
22:40:53Torneyou basically do it whenever you do a cache clean
22:41:10pamauryactually there are a bunch of these things in the code at the beginning so I need to figure out by myself :)
22:41:11Torneexcept it also applies to memory that's mapped uncached but buffered
22:41:24TorneHeh
22:41:29TorneWell, it's probably using hte MMU
22:41:40 Quit designate72 (Remote host closed the connection)
22:41:48pamauryI haven't seen any mmu code so far but that might change
22:42:34Tornewhich core is it specifically?
22:42:40Tornei.e. is it one with an MMU or an MPU?
22:43:06pamauryARM926EJ-S
22:43:19Torneright, so that's an MMU
22:43:26Torneso it will use it
22:43:32Tornebecause otherwise you can't set up caching/buffering.
22:43:45TorneARMs that have an MMU don't have the protection unit's cache/buffer range registers
22:43:56Torneyou have to write pagetables to configure which memory is cached or bufferd.
22:44:28pamaurysounds sensible, then I'll have to find the code to see how the mmu is configured
22:44:43Tornelook for it setting cp15 register c2
22:44:47Tornethat's the base address of the pagetables
22:45:09Tornealso bit 0 in c1 turns the MMU on
22:45:16Torneone or both of those should be easy to spot :)
22:45:32pamauryindeed
22:46:45Torneit's probably very near where you are :)
22:47:05Torneyou have to DSB after writing pagetables
22:47:23Tornethe MMU isn't hooked up to the write buffer so it doesn't see pending writes ;)
22:47:52n1ssaratoga: you are correct, the make install just sends in a zip command for fun but never uses it
22:48:36pamauryhum, I see lots of accesses to c7, c10
22:48:39pamaurybut none to c1
22:48:49pamauryor I missed one in the previous elf files

22:53:56Torneis there a seperate bootloader/
22:54:00Torneit's possible the MMU init was done there
22:54:08Torneand this code just relies on it already being in a known config

22:55:00pamaurywe don't really know. There is probably a bootloader loading the .sb file; but the .sb file also contains some init code
22:55:23Torneah
22:55:39pamauryperhaps there is something in the imx23 doc :)
22:55:47TheLemonManthe .sb is bootstrapped by the onboard rom
22:56:45bertrikI was wondering if maybe the bootloader was in the i2c eeprom on board the fuze+
22:56:49pamauryActually, I don't think the rom does more than reading the sb file and executing the instructions, so I must have missed it
23:00
23:00:10TheLemonMansearching for addresses in that doc is just awful :|
23:00:35pamauryTheSeven: I find it quite easy on the contrary
23:00:41saratogaamsv2 is ARM926EJ-S so you should be able to reuse it's MMU setup
23:00:48pamauryyou have a memory map at the end and a register list
23:01:15pamauryTheSeven: you are looking at the fuze+ firmware ?
23:01:19TheLemonManyeah, but i need to get the register name and search it in the rest of document to know what bit does what
23:01:39pamauryhow do you think people do ? :D

23:19:18AlexPI asked not long ago
23:19:49saratogahow large is large?
23:20:07bertrikpamaury, I'm seeing some difference in commands sent in sd-as3525.c and sd-as3525v2.c, do you know more about this?
23:20:31AlexPsaratoga: I can't remember
23:20:34pamaurynope, I haven't touch as3525 except for the usb core
23:20:40AlexPHVSC might have been involved
23:20:52bertrikfor example, for as3525, we try high speed mode only for v2 cards, while for as3525v2 it's done regardless of v1/v2
23:21:22tmztpamaury: ssp usually involves dma, especially for sound
23:21:30tmztpamaury: so it might just set it up early
23:21:46pamaurythat's at booting stage, I would be surprised
23:21:53pamauryfuck, that's fuze+ code doesn't make anysense, it's writing a reserved bit !

23:24:59Tornein which register?
23:25:10Tornevarious SoCs tend to extend ARM's CP15 stuff slightly
23:25:14saratogaAlexP: seems we agreed to enable it by default on the mailing list 6 months ago
23:25:43pamauryit's a clock register, not arm related as far as can tell
23:25:48Torneah
23:26:08AlexPsaratoga: I'm all for it; I just vaguely remember some counter reason last time I asked
23:26:14AlexPLt me check
23:26:23pamaurybut that's a shame, it set/clear a reserved bit from the start routine and I just can't tell what it's doing

23:34:54AlexPsaratoga: From my log searching, various people just said that as far as they know dirchache fails if you have too many small files
23:35:02AlexPBut I think this was all IIRC
23:35:20AlexPI *think* I tested with the HVSC with no issues
23:35:33AlexPBut someone should check then enable IMO
23:35:46gevaertsI think I unpacked HVSC three times on my clip
23:38:16AlexPgevaerts: With success, or did dircche fail?
23:38:39gevaertsI *think* it worked
23:38:45gevaertshm, this may not have been the clip
23:38:53*gevaerts can't remember any details
23:38:58AlexPYeah, I also think it did when I tried with one copy
23:40:50pamauryagain writing to a reserved bit, there is something strange there
23:40:51gevaertsIt must be in the logs somewhere
23:40:51AlexPThis is it, nobody has any concrete don't enable it, just a few "I think it might not have IIRC" type things
23:40:51AlexPI say we enable it personally
23:43:39Torneyeah, llet's just do it
23:43:40Torneif it breaks something horribly we'll, er, fix it.
23:43:40*gevaerts finds things
23:43:40AlexPTorne: Aye
23:43:40gevaertsOK, apparently when I unpacked four copies of HVSC, dircache didn't work
23:43:48gevaerts(on ipod video)
23:43:57gevaertsTwo worked
23:44:44gevaertshttp://www.rockbox.org/irc/log-20100828#22:35:29
23:44:44n1sgevaerts: does it fail gracefully?
23:44:44gevaertsn1s: well, I had to check if it was enabled
23:44:48gevaertsSo apparently, yes
23:45:38AlexPhow many files is 4 copies?
23:45:47n1swell, that sounds good
23:46:02AlexPyeah, 4 copies = stupid-amount-of-files
23:46:14AlexPand if it also failed gracefully, then just do it
