Consumer electronics, portables, whatever
In the most recent Lugradio podcast Episode 19 Season 5 at roughly 1h30 into the show, we got to hear a user’s write-in explain to the hosts about the benefits of using Rockbox on your ipods. Although the hosts aren’t very impressed… They also later on mention that they did get “a lot of mail about Rockbox” so obviously it is getting quite known out there.
Back at FSCONS ’07, I asked the guy doing the Openmoko presentation about whether they are going GTK or Qt, as his talk mentioned both and he didn’t really spell it out on what horse they were putting their money on. He then thought it was a really funny question and went on to explain how the Openmoko is like a small computer that can run anything you want. A bit like he was educating us that embedded devices do have CPUs that can run actual software. As if they wouldn’t have a main branch and a main development selecting one of these particular toolkits…
Many moon laps later, I discussed Openmoko with a friend over a few stouts at Snaxx 18, and he explained how he’d got one of the dev boards a long time ago and had kept up and tried a lot of versions of it and that it basically never worked to even make simple phone calls. He gave me the impression that perhaps the project wasn’t really that well run if it after this long still don’t have even the most basic functionality present and running stable.
Therefor I was happy to listen to TWIT 143 about the Dash Express and them telling me about it being based on the Openmoko platform. It felt like solid proof they are moving in the right direction then, so at least parts of the project must be functioning!
Then, to round it up it was with a big grin I read about the recent news that they are abandoning GTK and are now going to use E17 and Qt instead. Not a trace of any “this is like a small computer it can run anything” talk now (although I do understand that the statement was just something from this person and not any public endorsement from the project or so). This very same Ars Technica article says the first Openmoko based phone called Freerunner is going into “mass production stage next month” (that would be June 2008).
Personally, I can still see how making Rockbox run as an application on an Openmoko device would be a very cool thing.
I got the latest Linux Journal issue (#170, June 2008) the other day and while reading through it I fell over the article about a guy who found a GPL license agreement among the papers for his brand new Sony TV.
… and there he also mentioned that they use curl! Fun! Apparently in their “Bravia Internet Video Link” product. Whatever that is… “Stream, browse and watch internet video and much more on your compatible BRAVIA® HDTV with the BRAVIA® Internet Video Link. It’s like extra channels for your new HDTV.“
Robert Menes uploaded some photos of an early Rockbox port running on his SanDisk Sansa m240 (v1), and this much thanks to Dave Chapman’s early work. This port still lacks NAND driver and various important things so you still need tcctool to get code onto the target, but at least there’s evidence of progress now!
I have one of them mp3 capable mobile phones and I have a 4GB NAND flash inserted in it that is packed with music I like. Yet I never end up using it as a music player.
I see people everywhere use their phones for music and I repeatedly read and hear the soon coming death of the portable music player being predicted not far away by opinion-expressing know-it-allers.
My phone plays mp3 files just fine, but there are several reasons why I don’t use it for that. The primary one being that it gets a lousy battery run-time if I do that, and if I’d run down the battery all the way when listening to music then how would I be able to use the phone for regular voice? With a separate (Rockbox) device I can listen to music until the last drop of power goes out without hampering my communication abilities.
In my particular case, my phone’s lack of a proper standard USB port and it’s lack of anything but “full speed” (and yes full speed is less than high speed and is a lot slower than it sounds) when connecting it using the custom cable to my Linux box are two more reasons. Not to mention that it has this “database-only” approach to the music which I really don’t like – but yeah, I can learn to live with it.
Besides, it’ll be a while longer until I can hack my phone to run Rockbox and thus work the way I want it. Let’s hope Android or OpenMoko or similar efforts actually make it possible one day.
As I suspected and guessed in my blog post yesterday, Jason Kridner of Texas Instruments responded to the mailing list and confirmed that the “open platform” currently doesn’t even have a free-to-use assembler for the DSP in the DaVinci (which thus has less free tools available than the DM320 series!) and the gcc port seem to be mostly an idea so far:
I’m not aware of any solid plans on a gcc port yet, but I can confirm that TI plans to offer C64x+ C compiler and assembler tools similar to the way we provide the C54x tools for the current OSD. The restrictions and registration might not be exactly the same, but my view is that the important thing is to get something out there that any hobbyist can use for free. It doesn’t make a lot of sense for someone doing coding for use in their own living room to need to pay $3000+ for a full set of development tools when all they need is a C compiler they can run on their Linux box.
I acknowledge that Neuros really seem to make efforts to make things truly open and free, but TI’s ways are often far from straight-forward and obvious. Jason refers to his presentation from Lugradio live, but I don’t see how that clarifies anything on the openness front.
Neuros put out a press release yesterday saying that
“Neuros and Texas Instruments create new bounty program for next-gen Open Internet Television Platform“, and Joe Born of Neuros said on their mailing list that “it will be a complete open platform that will allow developers of all levels to contribute and port applications.”. You can also read some additional thoughts and ideas in the ARS Technica article called “TI and Neuros team up to build open source media platform“. It is basically a hardware platform based on TI’s TMS320DM644x DSP system-on-a-chip line, also called DaVinci. There’s no coincidence of course that the Neuros OSD 2.0 will feature that.
Personally, I’m not convinced when I see TI speak of Open Source since I’m fully aware of their history and I even believe that this brand new “open” platform still requires TI’s restricted-but-free compiler for the DSP. Of course it is more open than many other platforms, but I dislike when someone tries to sound all fine and dandy while at the same time they’re trying to hide some of their better cards behind their back.
A truly open platform would not give TI an advantage. It would offer anyone wanting to do anything with it the same chance. This platform does not. After all, having it built around one of SoC flagships should be enough for them and should be a motivator for them to make this as successful (and thus as open) as possible.
I think it is sad that Neuros repeatedly does this kind of statements. Their original “open source” player was never open source (to any degree). Their OSD player is largely open source but huge chunks of it is not. Now they try to announce even more openness for an entire platform and yet again they fail to actually deliver a truly open product. Neuros shall forever be known as the company who seems to want to do right, but always fails to in the end nonetheless.
Update: Joe replied on the list to my question about the DSP tool(s) and it certainly sounds as if TI may in fact release a more open tool and/or even a gcc port!? If that turns out true it will of course squash most of my complaints here!
A lot of people have asked me about my opinions on and comparisons between these babies, the Cowon D2 and the Meizu M6, and here’s my take. Of course a lot of this involves the original firmwares’ functionalities as that’s what I’ve been using on them so far. The Rockbox port for the D2 is progressing at great speed but isn’t yet capable of producing sound, and the Meizu port still has a long way to go (since it’s still in its infancy with research and reverse engineering being the primary doings atm).
Cowon D2
Touch screen isn’t really the best idea for a portable media player I’d say, but I must confess that the UI with “pop-up” buttons is rather nifty. See this little video for a grasp on how it works:
I haven’t used it a lot but the UI is working nicely and is fairly easy to use. I haven’t yet got myself an SD card to insert and try out, but I should soon! It does have visible tiny little screws that shows it could be disassembled quite possibly without too much efforts. Some of my other Rockbox friends are interested in the D2 quite a lot because it comes in a DAB model too, but my version is limited to FM radio only and even
Meizu M6
Next to the D2 this baby feels extremely small. It also has no visible screws or anything that reveals how it could be disassembled! The bootup procedure is first a bit silly since you need to hold down the PLAY key for a while but it doesn’t actually start until you release it, and you don’t know exactly how long you need to hold it. But then I think it proceeds nicely with the screen not even showing that it started, apart from a little “Loading…” text.
The M6 doesn’t use a touch screen but instead they have a “weirdo” slider pad with four button areas. Most of everything in the UI that goes up and down, like moving in menus, changing values, changing volume etc is done by letting a finger slide on the pad. This could’ve been a nice way of input if it wasn’t far too sensitive and thus I always seem to miss my goal menu item and have to go up and down several times before I manage to “hit” my target. Quite annoying!
Of course one downside with this player that isn’t a surprise at all but can be stressed, is the lack of any expansion slot so the original 8GB I got is all this unit is ever gonna see.
Conclusion
I think I end up liking the D2 somewhat more, mostly because of the slider on the M6 being annoying and that the D2 is expandable. The D2 also has a nicer OF (original firmware), but that’s not really what I care about since I plan to run Rockbox on both. Unfortunately I’ve not had a lot of spare time for actually getting into the hacking recently so right now I can’t comment on that much. I’ve seen interesting progress done by others in the mean time though!
I cannot say that the D2 is twice as good as the M6 so I’d actually say that M6 is a better value purchase.
Ok, that’s it for now. These are my first impressions, I’ll try to come up with some further ones later on after some more usage and hopefully some real rockboxing on them
I hadn’t gotten myself a new DAP in ages, and the last time I got one I had it donated to me from SanDisk. So it was 
really due time to get back into low-level fighting with Rockbox ports again. I ordered myself an 8GB Meizu M6 (SL) and a 8GB Cowon D2 (DAB-less), since both are very interesting flash-based targets with two very promising early Rockbox-porting efforts and we have data sheets for the SoCs used in both of them ( Samsung SA58700 and Telechips TCC7801).
I decided I should dive right in and also be able to do some nice comparisons of both these targets as they are quite similar spec-wise. Both units arrived at my place at the same time, so I got the chance to get a feel for them at once without any discrimination against either one.
Some first impressions without even having switched any of them on:
The M6 comes in a much smaller box indicating it’s “mini player” style already there. It was also much cheaper, almost half the price of the D2.
The D2 comes with a wall-charger but otherwise both boxes include earplugs, a driver-cd (windows stuff I presume) and a USB cable.
Comparing their physical appearances next to each other, there’s no doubt that the M6 is much smaller (even perhaps amazingly small – but yet with a screen that is considerably larger then for instance my Sansa e200) and I can’t help think that the D2 design is a bit weird has it looks as if it has something that can slide out but it doesn’t. I assume some of the D2’s extra size (thickness) is due to its SD slot (yes that’s full size SD not microSD) which is something the M6 doesn’t feature, not even a micro version. Both have USB mini-B slots and charges over that. The D2 has a small protective cover over the slot.
I’ll provide more fluff like photos comparing them against each other and against other targets soon as well, and perhaps something about how their firmware compares, the status of Rockbox on them etc. Stay tuned!
Update: M6 next to D2 pictures
It is with interest we in the Rockbox camp checked out the recent battle in Creative land where they shot down a firmware (driver really) hack by the hacker Daniel_K as seen in this forum thread.
We’re of course interested since we do a lot of custom firmwares for all sorts of targets by all sorts of companies, and recently there are efforts in progress on the Creative series of players so could this take-down move possibly be a threat to us?
But no.
In the Rockbox community we have already since day one struggled to never ever release anything, not code nor images or anything else, that originates from a company or other property owner. We don’t distribute other’s firmwares, not even parts of them.
For several music players the install process involves patching the original firmware file and flashing that onto the target. But then we made tools that get the file from the source, or let the user himself get the file from the right place, and then our tool does the necessary magic.
I’m not the only one that think Daniel Kawakami should’ve done something similar. If he would just have released tools and documentation written entirely by himself, that would do the necessary patching and poking on the drivers that the users could’ve downloaded from Creative themselves, then big bad Creative wouldn’t have much of legal arguments to throw at Daniel. It would’ve saved Daniel from this attack and it would’ve taken away the ammunition from Creative.
I’m not really defending Creative’s actions, although I must admit it wasn’t really a surprising action seeing that Daniel did ask for money (donations) for patching and distributing derivates of Creative’s software.
So far in our 6+ years of history, the Rockbox project has been target of legal C&D letter threats multiple times, but never from one of the companies for which targets we develop firmwares for. It has been other software vendors: two game companies (Tetris Company and PopCap games) fighting to prevent us from using their trademarked names (and we could even possibly agree that our name selections were a bit too similar to the original ones) and AT&T banning us from distributing sound files generated with their speech engine software. Both PopCap and Tetris of course also waved with laywers saying that we infringed on their copyrights on “game play” and “look” and what not, but they really have nothing on us there so we just blanked-faced them on those silly demands.
The AT&T case is more of a proof of greedy software companies having very strict user licenses and we really thought we had a legitimate license that we could use to produce output and distribute for users – sound files that are to a large extent used by blind or visually impaired users to get the UI spelled out. We pleaded that we’re an open source, no-profit, no-money really organization and asked for permission, but were given offers to get good deals on “proper” licenses for multiple thousands of dollars per year.
Ok, so the originating people of the Rockbox project is based in Sweden which may also be a factor as we’re not as vulnerable to scary US company tactics where it seems they can sue companies/people who then will have to spend a fortune of their own money just to defend themselves and then you have to counter-sue to get any money back even if you were found not guilty in the first case. Neither is Rockbox an attempt to circumvent any copy protections, as if it were it would have violated laws in multiple countries and regions. Also, reverse engineering is perfectly legal in many regions of the world contrary to what many people seem to believe.
If this isn’t sticking your chin out, then what is? 😉
