DIDJ Hacking

6 - Not sure what you mean by "The usb storage is being used now" : I may boot from the SD but not use it with available kernels?
7 - I don't know much about making a linux distro, doesanybody know of someone who might take on this task?

6 - Yes currently there is only SD Card support in bootloader 1.4 and the accompanying uboot, but not in the didj kernel, so for getting files onto the didj, transferring them over usb is the only way currently.
7 - Yes, I know of at least one person who is. He's upgrading the kernel to a newer more standardized version.

6 - Ouch! Will LF's linux - the one that normally runs the DIDJ - allow us to add files to the main storage? Or do we have to carry all exepriments with the DIDJ wired to the computer through USB?
7 - That is brilliant news to me, as I think it can attract more people who can then enrich this version

For now you'll need to transfer any files over usb to the didj

Can SDL get the keypresses from the didj's buttons yet? The demo NeHe app didn't seem to react to anything. I'm trying to get some SDL apps (GNUBOY) to compile for the didj, and everything seems to go fine so far except compilation blows up when it cant find the proper keymaps. Errors look like this:

  Code:

sys/sdl/keymap.c:38: error: 'SDLK_NUMLOCK' undeclared here (not in a function)

Any Ideas?

sys/sdl/keymap.c:38: error: 'SDLK_NUMLOCK' undeclared here (not in a function)

What happens if you comment out the line in keymap.c that SDLK_NUMLOCK is normaly declared?

ex: { "capslock", K_CAPS }, /* dup */
/* { "numlock", K_NUMLOCK }, */
{ "scroll", K_SCROLL },

Hi All, I was wondering how you go about recovering from a misconfigured 'make menuconfig' using the leapfrog 2009 linux?

Somehow I managed to bork mine, it had gotten set to arm9 but not lf1000, so all the leapfrog specific stuff was missing, I set it myself in 'system type' but of course, none of the leapfrog specific options were set. At this point I thought it would be a bad idea to compile the kernel

no idea how it happened, would having the wrong paths/environment variables set in a terminal then doing make menuconfig have caused this?

I had a look round the leapfrog distribution to see if I could find anything to recover the settings, I found 3 files in Didj-Linux-4222-20090422-1236/linux-2.6.20-lf1000/arch/arm/configs

lf1000_defconfig
lf1000_ff_defconfig
lf1000_ff_eth_defconfig

these files will pull in didj specific settings, although I'm not sure which of them I should use? Would someone that knows what they're doing mind taking a look at those files? or better yet post me a known working default ./configure file?

Could all those hacks for the DIDJ work with this? http://www.dealextreme.com/details.dx/sku.21968

Here (Argentina) we don’t even know the didj, but those “pmp mp5 players” are everywere and they are very cheap.

According google, those things have an ARM926EJ inside (Sunplus 8000), the same as the DIDJ.
And, they come with tv-out, sd card slot (2gb built-in), and a cheap camera out of the box.

I would be interesting to put an eye on those things!

Some of the Didj hacks may or may not work on this. ARM926EJ is just the CPU core used by Didj. The SoC (MagicEyes Pollux) has many more features than just the CPU.

That said, this looks like a pretty nifty little device. However we'd need a databook on the Sunplus 8000 to know what it can really do. I'd check for a community already working on it.

Hi, this mp4 player from DX is spmp305x based I think. Compared to the Pollux its just lame. Here are some links:

BUT ... DX has a Pollux:

I think this could very well serve as a stationary gaming console using a usb joypad.

I'm surprised no one has posted here about the gba emulator yet. I'm dusting mine off and soldering in a microSD slot tonight. It looks like there is work being done on using the updated explorer kernel and there appears to be a patch that makes it able to mount the SD card! I hope that sega & snes emulators come soon and thanks to everyone for the hard work that has gone into this!
