    GP32 Upper Memory Workaround ?

    No it's just saying that they dont start allocating virtual memory until 8mb after the physical memory to catch any out-of-bounds access in the kernel code. ie. any code that accesses this region is broken.

    Here's what I've managed to ascertain. I might try and get some code happening later, but I'll be leaving it alone for now. http://wiki.gp2x.org/wiki/Devdualcpu

    sorry, http://www.bootchart.org/ Thought I included it in the original post :)

    Gp2x Bootchart

    I'd say you can remove everything from 11s to 16s on that chart without trying too hard, but I'd rather someone with a serial cable and debricking skills tried it :). From what I can tell, init could be replaced with a small shell script that: mount -a # mount extra filesystems automount & #...

    The mmsp2 has some specialized video decoding hardware that is mostly secret and undocumented. The code that runs on the 940t offloads most of the work to it. There's no way a single 200mhz arm is decoding 720x576 videos on its own. (or even 2x200mhz).

    Initial Load And Splash Screens

    jffs2 is specifically designed for use on raw flash devices and embedded systems. It's a log structured file system designed to level to wear on these devices. It's not like the journalling has just been bolted on (ext3) If anyone has a better idea I'm sure lots of people would be interested...

    Gp2x Bootchart

    It's replacing init, the kernel is decompressed when the green screen comes up, and theres usually a few seconds of initialization before init is run. The menu is loaded at 16 seconds on this chart.

    Lan On Gp2x

    This is the g_ether driver, it makes the gp2x look like a network adaptor to the host pc. You still need a kernel with networking support.

    Gp2x Bootchart

    I risked bricking my unit for this rather boring chart. Seems most of the boot is spent doing sfa, but we don't have disk usage stats available in this kernel version, so it's likely that its reading from nand for a lot of the boot time. Clicky for the full chart, but I've pasted the...

    Muncher666, the 2nd core code is a bunch of binary junk at the moment. I'm not even sure if it's sure will be included in the "release" that is supposedly happening soon. The above code is the interface to talk to it, which is as much information as we have right now.

    If you look at the /dev/dualcpu stuff in the released sources it not hard to take advantage of, just very restricted in terms of formats. I'll give ffmpeg a bash later and see if I can get iPod vids working at all. Heres the video stuff...

    Lan On Gp2x

    wrong forum mate, this is for the GP32. gp2x has been met with limited success g_ether is working but only with a custom kernel. all of the "official" ones have networking support disabled.

    Any Ideas On Resource Files?

    plenty of "bin2c" or equivalent apps around.

    Ffmpeg

    Yeah the story is the same with software mplayer, since (surprise) it uses ffmpeg for most of it's decoding. For aac and flac you'll need extra libraries over standard ffmpeg.

    Run A Program At Startup?

    use /etc/profile for running stuff at boot. sucks i know. also, edit /etc/fstab and make / mount with rw,noatime to save on nand writes. I also added: tmpfs /tmp tmpfs size=4M 0 0 to /etc/fstab since screen creates stuff in /tmp, again to save on nand writes. I also: rm /var/log/wtmp...

    GP2X Python/pygame List Restrictions?

    Just load your png and blit it on after you draw the jpg. You might not be able to convert it do the display format without loosing the alpha channel.

    GP2X Python/pygame List Restrictions?

    Yeah this is exactly what I've been doing with PDFView. I keep previous, current and next images ready to go, and the next few pages are rendered and compressed in memory with zlib. Since most pdfs are fairly empty, the memory savings are huge. When you skip to the next page, the oldest is...

    GP2X Free Art ?

    Does anyone know of any free art or sounds that homebrew devs can use? Anything would be nice, but tilesets, units, explosions would be great. My projects are suffering from a bad case of programmer art.
