#rockbox log for 2016-11-22

00:00:17[Saint]I'm fairly confident however that most things that can draw using x,y coordinates can have both positive and negative values though.
00:01:07gevaertsWell, maybe, but I can't find code that does that in any of the lcd stuff in firmware/
00:04:09 Quit devsnd (Quit: Leaving)
00:04:23gevaertsah, found it!
00:05:23gevaerts[Saint]: as far as I can see, the negative number handling is in apps/gui/skin_engine/skin_parser.c, lines 2139..2185, in the viewport parsing code
00:05:38gevaertsSo I'm 99% certain it's only for themes, and only for viewports
00:06:12gevaertsConvincing me otherwise will require working examples or specific line numbers in the source :)
00:06:44[Saint]Hmmmm, fair. I'll concede.
00:07:54gevaertsAnyway, I'm based on what I assume __builtin is working on, I'm fairly sure this is entirely academical anyway :)

00:28:10[Saint]Hmmmm, I would rather like to piss around with USb audio on the Classic 6G but this requires some work on top of the Designware driver.
00:29:18[Saint]Hello tuaim.
00:29:30[Saint]Are you looking to lurk, converse, or seeking specific support?
00:30:12[Saint]Judging by the *-community traffic I'm guessing the former two as opposed to the latter one.
00:30:32[Saint]Anyhoo - welcome.

00:47:22[Saint]A /little/ off-topic, but does anyone have any specific recommendations for a segmented or LCD/OLED display in a Raspberry Pi Zero form factor Pi HAT?
00:50:42[Saint]I have mated a Raspberry Pi Zero, an RTC daughterboard, a HiFiBerry DAC+ Zero, and an 800mAh LiPo together.
00:50:42[Saint]I'm using a JEOS based on Debian/busybox and Warble/librockbox.
00:51:12[Saint]I have a basic DPAD I have constructed from dome mombrane compression switches.
00:51:47[Saint]I'm waiting on settling on a display before I commit to designing a case for it all.
00:52:48[Saint]The whole thing so far, has cost me less than $50 USD including shipping.
00:53:37[Saint]I kinda want to provide a hardware recipe and a software image as in 'in your face!" type answer to an open DAP.

00:55:57[Saint]One could also build this out of a Raspberry Pi 1/2/3 Model A/B/B+ and the HifiBerry DAC+ or HifiBerry Digi+

00:56:41[Saint]This would allow more room for physical controls, a much larger battery, and a nicer display.
00:57:44[Saint]If I did it that way I would still consider the JEOS approach but I would drop Warble in favor of our SDL app and use a nicer LCD/OLED display.
00:59:26[Saint]With a Pi 3 things get a little bit more exciting by having onboard WiFi and BT/BTLE radios.
01:00:01[Saint]But it is hardly a pocketable form factor - but honestly it is a pretty silly form factor even with the Pi Zero.
01:00:20[Saint]...still smaller than a Gigabeat or Archos, though. :P
01:02:11 Quit ZincAlloy (Quit: Leaving.)
01:03:20[Saint]Once I have a solid hardware package for A/B and Zero form factors I would like to look at selling kits to build Pi-based Rockbox JOES DAPs.
01:04:16[Saint]One issue I'm facing at the moment is very difficult to overcome elegantly due to the fact that Rockbox must be compiled assuming a fixed resolution. So I am handling it in a fairly inelegant way.
01:06:28[Saint]Presently I am providing two Rockbox SDL application instances, and deciding which one to launch based on detecting an HDMI connection. But this is something I might end up dropping altogether.
01:08:24[Saint]Unfortunately this doesn't work for the case of composite out, because you can't detect whether or not there is a display connected to either the coaxial or 3.5mm combined composite ports.
01:11:11[Saint]Another downside I haven't overcome yet is that I don't have any system deployed to charge the battery from a USB connection so it must be disconnected and charged.
01:13:05[Saint]This isn't too much of an issue with the Pi Zero and HifiBerry DAC+ Zero solution as the 800mAh battery with a debian-base/busybox JEOS and librockbox gets about 60~70 hours of lossy playback.

02:35:41__builtin[Saint]: so... if I call set_viewport from inside a viewport it gives me another viewport inside that viewport?
02:37:43 Join krnlyng [0] (
02:38:03[Saint]Yes. But I would be willing to guess you're not thinking about it in the terms it applies to.
02:38:24[Saint]Technically speaking any viewport set is a child viewport of the main fullscreen viewport.
02:38:56__builtinso would that mean to switch viewports I first need to "escape" to the default viewport?
02:39:24[Saint]How do you mean 'switch viewports'?
02:40:36[Saint]I'm not positive of how conditional draw is handled outside of the theme engine.
02:47:17__builtinalright, I feel like I'm misunderstanding viewports completely
02:47:54__builtinif I have this: lcd_set_viewport({x = 10, y = 10, w = 10, h = 10}), and then draw a pixel at (0, 0), will it be offset to (10, 10)?
02:56:07__builtinalright then something's up
02:56:08***Saving seen data "./dancer.seen"
02:59:13__builtin <<< should this clip things properly?
03:03:51__builtinWOW, I figured it out
03:04:00__builtinI was using drawrect() instead of fillrect()
03:10:57__builtinwell that makes most of the games playable now
03:24:40[Saint]I thought of a way to handle the naming scheme of the development and release builds.
03:25:04[Saint]I think we should consider renaming the dev builds to 'release' builds, and keeping the release and renaming it as 'legacy'.
03:25:55__builtinor we could just do releases more often ;)
03:25:56[Saint]Might help to clear up some confusion, as the only reason to use the release at this point is if you have one of the ancient old targets where we need to give a shit about binsize.
03:26:19[Saint]__builtin: it's really hard to orchestrate that with the manpower available.
03:27:50[Saint]There's only like...two targets where I would actually advise someone to prefer the release over the development build.
03:28:13__builtinwhen someone hears "release" they generally expect something that's been well-tested or at least not broken
03:28:26__builtinthe dev builds are not always that way
03:28:40__builtinsee the "#error lol" incident ;)
03:50:30[Saint]The who in the what now?
03:52:30*__builtin broke a few builds with "#error lol" recently

05:04:26TorCBilgus: Just downloaded the new build, and will install.
05:04:56TorC[Saint]: For your open DAP, have you heard about the EOMA68 computer coming out soon?
05:06:18TorCAccording to the latest update a few days ago, the designer has seen a working model of something that says the EOMA50 is feasible, and may be designed and released sometime after the second (in process) more powerful EOMA68 computer.
05:07:42TorCThe latter, being a CF card physical format, would be about the right size for a DAP. Probably a little bulkier than some, but could be made much smaller than others, or have room for a great big battery in a 2.5" HDD format DAP.
05:11:03TorCBilgus: by "filter first button press", I assume you mean the mode where the first press only turns on BL - though IIUC, you fixed that bug already.
05:11:27[Saint]TorC: it would be useless for this requirement.
05:11:37TorCGood reminder to pay attention to settings I don't use, though.
05:11:53[Saint]I need accessible GPIO and i2s at least.
05:13:28 Join toli [0] (
05:15:03[Saint]At the least I need tx/rx, USB, and i2s accessible, and it would need a decent quality DAC or 8 additional general purpose IO pins in order to connect one.
05:15:11TorC[Saint]: Ah. Thought I'd make sure. I suppose without those, you'd have to cobble together something that imitates USB HID. Though IIRC, there's something about pins that can operate in one of those modes upon request, but that might make the player too specialized a piece of equipment.
05:15:23TorCAnd more, apparently.
05:15:59[Saint]The Pi Zero is pretty much perfect but foolishly hard to obtain.
05:17:03[Saint]Pi A/B or Pi 2/3 B are significantly larger, but it opens up the door to a more general purpose device that can be both a fixed position media center and a portable DAP.
05:17:19[Saint]For varying definitions of portable.
05:17:22TorCI guess maybe I've been out of the rPi loop too much for too long.
05:17:46 Quit toli (Ping timeout: 256 seconds)
05:17:59TorCTrue, there are quite a few definitions floating around. Pick whichever one you please... Just like standards :)
05:20:01[Saint]The Pi 3 B seems like the obvious candidate, as it is:
05:20:01[Saint] - available in bulk
05:20:01[Saint] - has onboard BT/BTLE and 2.4GHz WiFi
05:20:01DBUGEnqueued KICK [Saint]
05:20:01[Saint] - has 10/100 Ethernet
05:20:02[Saint] - can PXE boot and USB boot
05:20:02***Alert Mode level 1
05:20:02[Saint] - is big enough to provide a decent LCD/OLED static or touchscreen experience
05:20:04[Saint] - has plenty of room to kludge the RTC daughterboard and battery in there between the Pi itself and the digital/analog DAC/AMP daughterboard
05:22:06[Saint]I think I will just end up forgetting about the potential use case of a fixed position Rockbox JEOS media center as it makes the use case of the external display very fucky.
05:22:41[Saint]Unless I was to rip off the combined composite and 3.5mm unamplified stero jack off the board.
05:23:01[Saint]I can detect HDMI jack sensing, but not composite jack sensing.
05:24:18[Saint]So I can't tell the JEOS to conditionally boot either the the SDL app instance built to match the Rpi's Videocore framebuffer resolution, or the SDL app instance built to match the onboard LCD/OLED display resolution.
05:27:55BilgusTorC actually I re introduced it but fixed it again :)
05:29:24BilgusI'll be committing a more polished version shortly if you want to wait a few

05:43:07TorCBilgus: I'd already long installed it by the time I got your last note.
05:45:54TorCInitial test shows none of the problems I remember just now to test for, and has a nice, responsive backlight.
05:46:28TorCOne oddity, but not that big a deal: Volume no BL only works on WPS (of the screens I've tested so far).
05:46:53TorCIn file browser, etc. the backlight comes on anyway.
05:52:30Bilgusno its will only work in wps and fm
05:53:23Bilgusit could be expanded i suppose but i see no real need since you need to see what you are doing in those screens
05:53:43TorCMakes sense, on the whole. Arguably volume should work elsewhere, but the other keys need to come on in the other screens as you mention.
05:54:26TorCA case can be made both ways. It just surprised me when I saw the BL come on with volume in non-WPS.
05:55:07TorCThere is, of course, no play/pause/seek/skip elsewhere, so the question of those working elsewhere is moot.
06:00:02TorCOr if you prefer, they'd better trigger the BL anytime they don't have the WPS function, which the volume does in most cases - and probably the reason I was surprised by the current behaviour.
06:02:17Bilgusthe filtering only occurs in fm and wps not that it is hard to add more contexts I just don't see any value in it
06:03:13Bilguskind of like how softlock only works in those places where it is really useful
06:08:59TorCNP. Understandable. Might be worth adding a note to the manual, though the people most likely to ask here probably won't read it.
06:10:26 Join alexweissman [0] (
06:10:57TorC"It should be understandable without the manual," they say.
06:11:06Bilgusthat is assuming it even gets added to the builds so I guess when the time comes if it becomes a problem it can be addressed
06:12:13Bilguspersonally it would kind of piss me off if I was in the middle of a screen other than wps or fm and every button didn't enable the backlight
06:12:21TorCI'll write the first draft for the convenience of updating.
06:13:12TorCI suppose it's true. One advantage of the volume keys enabling BL outside of WPS/FM is they become a safe way to turn it on, just like down in WPS.
06:13:56TorCKind of like the "First press enables BL" in the dangerous mode for advanced users.
06:14:25Bilgusalso I added the disable on external power and save settings when turned off
06:14:40TorCI'd forgotten about that use case for volume turning on BL.

06:26:02[Saint]don't worry about translations, these are handled by volunteers.
06:26:29[Saint]you just need to handle english.lang

13:10:02pamaury_we could upgrade ct-ng in to 1.22 since ypr0 toolchain doesn't build anyway...

17:29:46devsndpamaury, I finished the lcd init code for the init_seq_0 yesterday as well, but didn't get around to try to draw something on the screen
17:31:22devsndand also I did not understand some parts of the init_seq_1 that reference some addresses; some if which seem to be constants, others not however. Do I have to read those locations from the device memory?
17:32:26pamauryno you can't, those are usually variable that the OF driver uses, typically screen size, orientation. I'll have a look. The datasheet can help.
17:32:36pamauryBut I'm not available until 21:00 tonight
17:33:02devsndsure, thanks
17:33:09pamaurylook at the other drivers as well, there are comments. And look at real drivers in rockbox (firmare/target/arm/imx233/sony-nwz/lcd-*.c)

22:19:16lebelliumyes, because it didn't work without
22:19:34pamauryah, what prefix did you choose?
22:19:41lebelliumwell, I did "rm -rf /tmp/rbdev-build"
22:19:44lebelliumwith tmp
22:19:50pamauryno I mean for
22:19:56pamauryRBDEV_PREFIX=~/arm-sony-linux-gnueabi ./
22:20:14lebelliumI didn't change the prefix
22:20:20lebelliumI just typed what you wrote
22:20:37pamauryok, so rm -rf ~/arm-sony-linux-gnueabi/
22:20:48pamaurysorry for the mess
22:21:06lebelliumNo, I'm sorry
22:21:17lebelliumsince I don't understand what I'm doing, that's not easy
22:22:19pamauryok, well the prefix specifies where the toolchain is installed
22:22:35pamaurythe first thing did is to download and install a tool called ct-ng
22:22:53pamaurybut the version was too old, so I changed it but you have to remove the old first
22:23:23pamauryas for /tmp/rbdev-dl/, that's the temporary build directory, the script won't let you run a new build in an existing directory, for safety reasons
22:26:23lebelliumso I did:
22:26:29lebelliumrm -rf ~/arm-sony-linux-gnueabi/
22:26:35lebelliumrm -rf /tmp/rbdev-build
22:26:39lebelliumRBDEV_PREFIX=~/arm-sony-linux-gnueabi ./

22:41:15pamaury__builtin: I think -W inhibits all warnings
22:41:35__builtinit's far too many to fix by hand
22:42:11pamaurylebellium: ok, we have a problem, apparently you have crosstool 1.13.2 installed in /usr/local/bin, I guess from the ypr0 toolchain
22:42:18pamaurywhich is why you have the error
22:42:25lebelliumI have a working toolchain for YP-R0
22:42:34lebelliumI'd like to keep it working if possible :P
22:42:58pamaurycrosstool is not used by the toolchain, it's only the tool to the build the toolchain
22:43:33pamaurylet me see if I can add some version check to
22:43:53pamauryhonestly I really recommend against installed toolchain in /usr/local but too late for you now :-p
22:44:35lebelliumI don't know how I got it but I have a working toolchain without pain while dozens people here complain all the time it doesn't build
22:44:41lebelliumso I don't really care where it is :P

22:51:49pamaurywodz: you might be right
22:52:20pamaurybut then it means I have to discover how one builds a toolchain with glibc and all its crazy complexity
22:54:21pamauryif I understand correctly, ct-ng builds gcc in two steps (twice ?)
22:55:12pamauryI'll look into it

22:58:50wodzpamaury: I know quite a few tools build compiler twice but I can't understand why in case of crosscompiler. On non crosscompiler you build twice to have 'pure' version - first compilation uses whatever compiler you have to build bootstrap compiler and then actual compiler is built using bootstrap.
22:59:23wodzpamaury: Maybe this is the same with the twist that final compiler targets other architecture
22:59:46 Join krabador [0] (~krabador@unaffiliated/krabador)
23:00:23pamaurywodz: I think it has to do with linking
23:00:33pamauryfirst you build a bare-metal toolchain, to build glibc
23:00:58pamauryand then you build a toolchain that targets glibc, but it needs the glibc library, header and linker file I guess
23:01:16wodzpamaury: you are right
23:01:25 Join [Saint] [0] (~sinner@rockbox/staff/saint)
23:01:26pamaurymaybe that can be done in one step, since those don't really need glibc to be built
