A few unanswered questions

I have a few questions which I couldn't seem to find the answers to on the Linux Wiki.

What is on the software CD that comes with the MP3 Kit. Is it really necessary?

Has anyone been able to convert videos into a format playable on Juicebox?

Can the Juicebox support any size SD card? Or is the maximum really 512MB as stated by the manufacturer.

What is on the software CD that comes with the MP3 Kit. Is it really necessary?

basically whats on the cd is a driver for the usb->sd/mmc card, which really isn't needed for most windows systems. it also includes an application to convert pictures into the juicebox format. there are several OSS applications which can do this conversion under linux. looking at the code, it should be easy enough to write one for winblows. basically its worthless for most people. i have about 20 cd's that i was considering making a lamp out of similiar to AOL cd lamps.


Has anyone been able to convert videos into a format playable on Juicebox?

this question is a little vague....

if you are asking if someone can use the juicebox to play videos, then yes, i have loaded uclinux with a small video player and can play mpg movies.

if you are asking if someone has been able to use the video player program that is available with each of the Juiceware Cartridges, then no. the emplayer is proprietary software from emsoft and their codec appears to be some non-standard format. each juiceware cartridge contains a copy of the emplayer program.


Can the Juicebox support any size SD card? Or is the maximum really 512MB as stated by the manufacturer.

emsoft didn't implement VFAT for their sd/mmc card support, only FAT16, which has a maximum limit of 512MB per partition. there have been different reports of using a 1GB card, but from my personal tests and from looking at the code, 512MB is the max size using FAT16. i use EXT2 on my sd/mmc cards and can use the full 1GB

Is the default uclinux already on the Juicebox capable of playing mpg files? Or would I have to load my own uclinux via xD/Smart Media.

Does Juicebox support the EXT2 filesystem?

Are there any sites or pictures of Juicebox with someone who has loaded their version of uclinux on it?

the version of uclinux that is in the onboard OTP flash does not contain an MPG player, so you'd have to do a custom version of uclinux and load it via NAND flash.

no the version of uclinux that is in the onboard OTP flash does not support EXT2

But are there any pictures of Juicebox with a ucLinux kernel running?

Also, how's the quality in mpg playback on the Juicebox? Should I expect it to be the same as the demo on the ROM?

no i never posted any "pictures" of uClinux running. what would be the purpose of that?

once you scale the mpg to the lcd resolution the video playback is very good.

Well I was more curious as to the look and feel of it? I'm not that familiar with linux in general. But I was hoping to see something similar to a shell.

thats the beauty of uClinux/Linux once its up and running, there are limitless possibilities for what you can do. you can run microwindows or numberous other GUI's in the FB.

i don't recal the quality of the demo video, but its certainly better than any of the juiceware carts i viewed. i've watched several movies on mine while traveling, and found it totally acceptable for the screen size.

I have a question - where did you get this "small video player" from? Was this something you wrote yourself or obtained as freeware? I'd be in interested in locating it.

Thanks a lot.

Hi,
Can the newer Juice boxes with only 2mb ram be hacked to run your own version of uClinux ?
