Hi!

Last days I read a lot about embedded linux and flash devices:

Ipronto is working with jffs2 - a file system for devices with flash rom instead of hdd.

The memory is partitioned into 7 partitions:

0 - boot image
1- linux kernel
2 - filesystem (I think this is what is called "root file system")
3 - intent
4 - storage
5 - epg
6 - icf

what i found out while analysing the update script: Everything is ok as long as partition 0 is untouched. If you modify the kernel image or the file system the worst what can happen is ipronto will crash during boot sequence.

In case of crashing linux kernel just run the original update process and the firmware is restored. After that the ipronto should work fine again.

But NEVER touche partition 0!! If this partition is damaged, Ipronto will not boot and there is nearly nothing you can to by yourself to restore the system.

p.s.: Today i downloaded the vmware player and a suse machine where i will try to mount the jffs2 image. I hope it works.

Hi Mich,

thanks for the link. Funny ....

If you google for "java applets ..." you will find many on the web. It seems that even some of the 1.4 version apps are supported with the iPronto browser, I was surprised!

I didn't find anything with sound. Did you find a demo applet with sound? Just to see if java can access the speakers ....

Best regards,

Kalle

Hi!

I was also looking for an applet playing sound. I didn't finy any working on the ipronto.

I didn't recognize any system what java version is running and what is not. All applets made by myself have to be compiled with "-target 1.2 -source 1.1" and than you fine 1.4 version applets - i am a bit confused.

Actually I am trying to write into a file but after each write operation the file is complettly empty. I think it would be so helpful to have the capability to edit files.

Hi!

You can download the Source for RC9800 from the philips page.

Who we have to send flowers to get the source for the ipronto?

Hi!

This there good and bad news:

I updated my file editor and now it is able to write files, but

good:
I was not able to cut files - so you can not make files shorter than they are.
I display read and wright rights of files and directories, but it seams these java functions are not working correctly - so don't trust in "rw" :-)

bad:
Last time I talked about mounting a jffs2 image at alinux machine. It seams this dowsn't work or it is more difficult than I thought.

Hi,

semi newbie who has been using ipronto for a bit but would love to be able to get it to play streamed music from my nomad music streamer.

my pocketpc can do it, surely this can too?
Unfortunately without the source code I don't think we'll be able to modify what we have but may be able to start again. It shouldn't be that difficult to create a new linux image that will contain video player / mp3 player.

I have some linux friends who may be able to help out on this.

I have previoulsy converted my ipa3800 to running linux with the info at handhelds.org, I'll have a look in more detail at what is going on overe there. They have a linux distro for the X-Scale which should work

Does this work? I'll also try this when I get home

Fortunately the most games/graphic demos are working very nice :-)

However, it seems to me that the browser of the iPronto is not able to produce sound - or somehow this feature just turned off.

No sound at all :-((((

If you find the config file to enable it just let me know :-)

Best regards,

Kalle

It seems that the ipronto will never be able to play sound as all sound calls are made using 'hostjni' (I'm not sure excatly what it means) but the basics are that all sounds calls make a call to the local filesystem for the file.

i.e the beep is on the locl afilesystem and even if an applet asks for say 'bong.au' it will work if that bong.au is on the local filesystem but won't if it is a remote file.

So in otherword s.. no sound is possible at all

I have also found out how to get a bootloader prompt on a serial connection, this will allow you to boot any linux X-Scale image, if anybody thinks thay may have eeven the slightest bit of interest in how to get a different linux image on this device then ask

Hi!

The folder "/storage" is writeable for applets. So an applet could write he soundfile into this folder and play it from the local filesystem.

misch

Hi!

How did you get the bootloader prompt on a serial connection?

misch

Carry on guys ! I don't understand a word but it seems very interesting ... Anyway I hope you'll find what we are all looking for because I love this remote too !!

Interested ; I send you an MP with my E-mail
Thanks & Best regards

Your Photos were well received - Thanks -
(Are they shot with a mobile phone ?)

They are now on my "Ipronto web zone" ;)
