11:07 -!- tala is now known as tala2xlc
11:09 < tala2xlc> TheSeven: I would like to get the ipod accessory protocol up and running on the ipod classics - is there currently a way to get UART up and running at all?
11:31 < TheSeven> tala2xlc: back in the old days, someone did a few dumps through the UART, so I'd guess that it shouldn't be too hard to get it running
11:32 < TheSeven> i have a UART cable somewhere... but where?
11:32 < tala2xlc> TheSeven: Is there already some e.g. patch for rockbox to have some basic UART stuff running?
11:33 < tala2xlc> I got one around, but I think that won't help you... :-)
11:33 < TheSeven> no, the IAP and UART code is currently one huge mess, and heavily tied to the PortalPlayer platform
11:33  * TheSeven found his cable
11:33 < TheSeven> getting the UART going is probably the easiest part
11:34 < TheSeven> separating UART from autobauding and IAP probably the harder one
11:34 < tala2xlc> I looked through the current serial.c / iap.c implementation - can't we just reuse the existing code on top of it?
11:36 < TheSeven> the last time I looked at that, serial.c contained all kinds of things from several uart drivers to autobauding and even a GDB stub
11:36 < TheSeven> and there were PP register accesses all over the place
11:37 < tala2xlc> hm...I see...so basically a complete new implementation of serial.c is required for the classics then
11:39 < TheSeven> a few months ago, someone announced an attempt to clean that mess out and properly separate the UART driver from the rest
11:39 < TheSeven> i think it was bertrik
11:42 < tala2xlc> so that means that everything is basically "a big mess" with lots of work to do or a completely new "library" for serial / iap is required for the classics (in order to have a clean basis)
11:45 < TheSeven> yes, something like that
11:45 < tala2xlc> doh :-)
11:45 < TheSeven> one should separate the drivers out of serial.c and move them to the target tree with a standardized interface
11:45 < tala2xlc> yupp
11:46 < TheSeven> once that's done, implementing the ipod classic uart driver shouldn't be much work
11:46 < tala2xlc> yes, since that's just on top of the driver and basically the same for all ipods (current as well as previous models)
11:48 -!- nieuwbie [~user@ip4daa4a6f.direct-adsl.nl] has joined #freemyipod
11:49 < nieuwbie> Hello, I want to compile a GNU arm toolchain, so should I just configure it normally (./configure && make) or I have to specify a certain target as well?
11:50 < TheSeven> i'd suggest to use the rockboxdev.sh script
11:50 < nieuwbie> ok
11:50 < tala2xlc> TheSeven: Where can I get the code that was used to do the dumps over UART?
11:51 < TheSeven> svn co svn://svn.rockbox.org/rockbox/trunk/tools tools && tools/rockboxdev.sh
11:51 < TheSeven> choose the eabi ("e") toolchain
11:54 < nieuwbie> TheSeven: Is that command above execute a rockboxdev script? I'm asking because I've got a message 'ROCKBOXDEV: no write permission for /usr/local'.
11:54 < TheSeven> oh yes, you'll need to run rockboxdev.sh as root
11:54 < TheSeven> so probably sudo tools/rockboxdev.sh
11:55 < nieuwbie> TheSeven: So that means that will install the toolchain automaticlly?
11:56 < TheSeven> yes
11:56 < nieuwbie> TheSeven: Strange, I invoked the command as root via sudo and the same message occured.
11:57 < TheSeven> if you placed the sudo before the whole line, it will only be effective for the svn command, which doesn't need root privileges
11:57 < TheSeven> as you already have the checkout, just run "sudo tools/rockboxdev.sh" now
11:57 < TheSeven> tala2xlc: http://pastie.org/1511396
11:57 < TheSeven> that's a simple UART echo
11:57 < nieuwbie> TheSeven: That's what I thought, thank you.
11:58 < TheSeven> this was written for the nano2g, but IIRC it should run on the classic as well
11:58 < tala2xlc> ok, thanks :)

12:03 < TheSeven> yes

12:21 < TheSeven> need to divide&conquer the clock gate

12:29 < tala2xlc> man you're fast... :-)
12:31 < TheSeven> for 20 lines of code?
12:32 < tala2xlc> lol ;)
12:33 < TheSeven> now build a shell using that :)
12:34 < tala2xlc> I will try my best! Thanks!
12:36 < TheSeven> of course one should figure out how to make that interrupt-driven instead of polling it all the time
12:37 < tala2xlc> I just thought about that, too - sleeping / waking up cyclically is rather...CPU consuming..

12:54 < fmibot> r495 build result: emcore: All green!
12:54 < fmibot> r495 build result: embios: All green!
12:58 < tala2xlc> hrhr...at least with 10k cycles we won't miss a single bit...
12:58 < TheSeven> that's not true
12:59 < TheSeven> the scheduler will only wake up every 10ms, so if nothing else needs the CPU, the polling rate will effectively be 100Hz
13:02 < nieuwbie> TheSeven: Why UART is so important for you guys?
13:03 < tala2xlc> I would like to get the iPod Accessory protocol up and running
13:03 < tala2xlc> you're then able to control rockbox e.g. via your car (if you have a car integration) or remote control it via some other devies (home stereo etc.)
13:10 < TheSeven> hm, our UI lib needs a list chooser implementation
13:11  * TheSeven wonders how to do that as flexible as possible

14:23 < TheSeven> [Saint]: what kind of UI library functionality would you need?
14:23 < TheSeven> (especially regarding list-based choosers)
14:41 < tala2xlc> you mean like list selection e.g. browse through harddisk content?
14:43 < TheSeven> yes
14:44 < TheSeven> or boot menus, or configuration menus, or maybe just a bunch of icons that get highlighted and can be hit by a button :)
14:44 < tala2xlc> ok...
14:44 < tala2xlc> from my point of view (usability, abstraction) I seriously like the ipod list-based choosers
14:45 < tala2xlc> the abstraction is quiet nice -> press select -> you go into a menu, press backward you get out of the menu
14:45 < tala2xlc> similar to the rockbox style
14:46 < tala2xlc> holding select can lead to a menu that enables the user to configure something that has to do with this list entry (e.g. delete directory, rename or whatever)
14:48 < tala2xlc> I think even for other players (!= ipod) this is quiet okay - you'll always have some up / down / ff / fb and a play or select button
14:48 < TheSeven> at least unless it's a touchscreen device
14:49 < tala2xlc> well...touchscreen: cowon has some similar menu structure for the J3
14:49 < tala2xlc> you scroll upwards / downwards with your finger
14:49 < tala2xlc> selection: press the entry
14:49 < TheSeven> yes, that's rather intuitive :)
14:49 < tala2xlc> :-D
14:49 < TheSeven> but i'm more concerned about how to merge those into a unified interface, if that's possible at all
14:51 < tala2xlc> I think so
14:51 < tala2xlc> I did some research for a company on how to abstract different types of gadgets into a unified user interface
14:52 < tala2xlc> at the end the best abstraction for pretty much any information was a list like interface
14:53 < tala2xlc> you could have methods such as: SelectNextEntry(), SelectPreviousEntry() -> used e.g. by ipod's scrollwheel, but for touchinterface you would use SelectEntry(uint entry).
14:56 < nieuwbie> TheSeven: I used on extract2g on dump.img but I've got just one file.
14:57 < TheSeven> nieuwbie: context?
14:57 < nieuwbie> TheSeven: The file names cD?A.fw
14:59 < TheSeven> what are you doing?
14:59 < TheSeven> what kind of dump?
14:59 < TheSeven> what's cD?A.fw?
14:59 < TheSeven> what do you want to achieve?
14:59 < nieuwbie> TheSeven: I tried to extract firmware from my first generation ipod classic.
15:01 < nieuwbie> TheSeven: using instruction on the wiki. I tried to list files using extract -l command but it returned a message 'unknown header...'
15:01 < TheSeven> then you're apparently not using the right input file
15:04 < nieuwbie> TheSeven: hmm it has 80GiB...
15:04 < TheSeven> huh?
15:05 < nieuwbie> TheSeven: I dumped everything from my ipod ussing dd.
15:05 < TheSeven> apple firmware or rockbox?
15:06 < TheSeven> can you see the firmware partition on that particular ipod?
15:15 < nieuwbie> TheSeven: apple firmware
15:15 < nieuwbie> TheSeven: How to see it?
15:15 < TheSeven> with any partitioning utility
15:18 < nieuwbie> oh, stupid question
15:20 < nieuwbie> TheSeven: There is only one partition.
15:20 < TheSeven> then you can't extract it using extract2g
15:20 < TheSeven> you'll need to grab the firmware from phobos and use that
