Rockbox

I was just told about it by zivan56, and my mi4 page was just updated: the SanDisk Sansa View uses the mi4 file format and it is clearly PortalPlayer based. mi4code can find the crypto key, so decrypting it for disassembly is easy. In fact, the zip contains two mi4 files and the second one [...]

Well, not really but at least the recent “jailbreak” for it opens up the possibility… The jailbreak seems to open up the ability to run apps on the target that are built for it, so I figure it can then theoretically be used to run whatever, and that’s why I say it is an opening for [...]

Enhancement, improvement or optimization: Metadata-on-Buffer committed; this involves a largely rewritten playback buffering engine.

A few guys are now discussing Rockbox for the D2 in the Rockbox forums. The D2 is a Telechips equipped 2/4GB flash based player with a 2.5″ 320×240 touch screen and an FM tuner. Recent progress are thanks to the tcctool that can upload code to a telechips MCU and execute it, thanks to the “usb-boot” mode.

Dave Chapman once considered a Rockbox port to this device, but has recently decided to skip that idea. So whoever were holding your breath: get another target model and start breathing again! Or possibly get someone else interested enough to get the porting back on track again!

Enhancement, improvement or optimization: Big speed increase in PluginMpegplayer for ColdFire based targets. (Iaudio x5 and m5, Iriver h100 and h300)

In Rockbox we’ve seen the gcc 4.2.x series introduce warnings on C code that really is perfectly fine, and also compiles warning-less on all other versions of gcc. (We use the 4.2.x series in Rockbox only for the simulator, built for running on host.) In the linux-mips project, they’ve found gcc 4.2.2 to not even be [...]

MrH updated his Semi-Independent DMA Interface docs for the PortalPlayer PP5024, now at 0.6.

Bugfix: The problems with the Sansa bootloader failing to start the OF should be fixed with the newly released sansapatcher 0.5

USB in Rockbox land was originally a matter of supporting the USB bridge chips in the first targets we supported (the Archos ones, the irivers and the iAudios). Since the USB stacks moved into pure software in the used soc chips, Rockbox has (unfortunately) relied on the original firmwares (the so called OF) to provide USB [...]
