Blogging, cURL and libcurl, Rockbox

Vacation days are slow days

I just wanted to drop a note saying that the biggest explanation for the silence and slowness of my blog the last couple of weeks have been my ongoing vacation, which is still going on for another two weeks.

Of course things are happening still, but due to my lack of computer time right now I tend to prioritize actually working with those things rather than posting here writing about the stuff I do/read/fix.

The Rockbox Steering Board vote is over, results will be published soon (spoiler: I’m voted in as one of the members). There’s a curl release coming up for August and we still have a few outstanding issues to fix. More on these topics later!

Rockbox on the Onda VX747

7 Comments

Maurus Cuelenaere has been very busy lately with his work on porting Rockbox to the Onda VX747 player. This 3″ LCD 4GB/8GB flash player isn’t just touch screen and very ipod touch-looking, it is also equipped with the Ingenic Jz4732 chipset. This is particularly interesting because this baby boasts an XBurst processor, which has a MIPS core clocked at 240 to 400MHz.

In other words: this is the first MIPS-based target Rockbox is being made for. Maurus has custom code running on it, we have rockboxdev.sh adjusted to build a MIPS toolchain and there seem to be a handful of other Chinese PMP players using this chip family so this is a good chance to get a whole bunch of new targets at once. Just join the fun!

Get all the latests news on development for this target and chipset family in this forum thread.

Normally I would link to the company’s official page about a player but this image will take you to a gadget blog site, simply because I cannot find any official site or page for this device!

24 different targets and 8 beers

This evening we collected all the different targets we have represented here at the Rockbox devcon and made little picture of them. We managed to pull together 24 different models for it. All these devices run Rockbox, although some of them are not really mature ports. 9 different models didn’t make it to the picture since they failed the runs-Rockbox test! 😉

The beers happen to show some the liquids we’ve been enjoying here!

See all Petur’s Devcon 2008 pictures here.

You just have to go there to watch the biggest Tower of Rockbox yet. I’m sure it’ll pop up in the tower of rockbox wiki page on the rockbox site soonish.

Topics: release 3.0 about 55 minutes

Some little about gsoc2008

GPLv2 discussions about 1h:00 in

Rockbox Devcon kind of starts today

In just a few hours I’ll take off to Berlin to go visit The Rockbox International European Developers Conference 2008. This year is hopefully going to become the biggest devcon so far. If you’re in Berlin this weekend, show up and say hello!

For you people living on a continent more to the west, keep your eyes open for DevconWest2008, probably taking place August 22nd to the 23rd somewhere in the US.

Portably Yours

Archos PlayerOne day in late 2001 I had a talk with my brother Björn and our mutual friend Linus about how their portable MP3 player was very cool but the software/firmware on it was rather limited and lame in many ways. (Correct, I didn’t own any portable music player at that time). As usual, we brought up the idea about being able to hack it yourself and oh how good couldn’t you make it then? Not very long afterwards, we had a mailing list setup for discussing how to reverse engineer and improve the Archos Player firmware. Personally, I had no device yet but it sounded like good fun so I subscribed and participated from the start. After a few months, I got myself an Archos Recorder to be able to get down on the metal too, and the Recorder was also slightly different and thus brought some more challenges to the team.

Archos Recorder

Archos RecorderThe Recorder was a step forwards since it provided better sound and a (gasp!) graphical LCD. Some of the first work I did in the Rockbox project was to work on the code for the LCD, to bring text to it using fonts and to provide line drawing routines etc. Keeping the entire screen in a separate “frame buffer” that is updated to the screen with a lcd_update() call was an early design decision that has stuck ever since.

We took the Rockbox a long way supporting more and more of the early SH-based Archos targets, including the V2s, the FM and the Ondio series. But eventually of course the models started to get hard to get and out of production. It was time to start looking into moving to other targets, and other targets would more or less force us into a world with software audio codecs!

I got my original Recorder stolen, but I had it replaced and put in a 80GB disk and it was much rejoicing.

iriver h140

iriver h140We did scan the market for targets that used somewhat standard components for which we could get specs and docs and we found the iriver h1x0 series and the work began. As usual we got plenty of help from everywhere and it didn’t take too long to show the nay-sayers that we could indeed transition Rockbox into the future with software codecs. We also took it to the h3x0 series with its color screen not that long after and my golly, didn’t an entirely new world of opportunities open? 40GB of disk was just about enough to hold most of my music collection.

iAudio X5

iAudio X5What’s the fun of Rockbox if I couldn’t follow along? I got the iAudio X5 early on in the porting effort and joined in and got my first color-screen target. Of course I didn’t like how the mere 20GB disk narrowed what music I was bringing with me, but hey some sacrifices had to be made for the greater good of advancing Rockbox! 😉

Rockbox was now booming and flourishing, coming to new targets all over and getting more and more developers involved.

Sansa E260

Sandisk Sansa e260A guy from SanDisk contacted us asking about a Rockbox port to their Sansa E200 series, and even though they sent me a bunch of targets etc they never provided any docs or actual help on the effort of porting Rockbox to these babies. Not even the figuring out the firmware format, as that was instead made by our own secret super-hero MrH.

Meizu M6

Time flies and soon enough (like in the late 2007) none of the targets Rockbox ran fine on were no longer being manufactured and started to get hard to get in shops all over the world. The eternal race to get Rockbox ported to a currently manufactured model of course just got more important.

It was almost two years since I got the Sansa e200 series from SanDisk and it was time to join in the efforts of bringing Rockbox to some Meizus. The amount of interested people and the existence of a (leaked) data sheet for the main SoC helped me settle for buying this.

Cowon D2

As I’ve already explained, I bought a D2 too at the same time I got the Meizu so that I could do comparison for people and just play around some extra.

Of course, my timing is dubious as I got my two new targets exactly at the same period in my life when I went back to work (almost) full-time from having been on paternity leave for six months. Together with my extra “admin duties” such as the euro devcon and gsoc 2008 happening, I really haven’t had much time to actually dive into low-level fiddling with the ports yet. Hopefully I soon get adjusted and get some time to really help out.
