found some info about the processors

i'll try to find a wiki about all this stuff
mabe in the pxos website(has a wiki but it's hidden(in developement))

i was asking if someone knows the chips that are inside such as the cpu etc... in order to know if porting linux on them is easy or not

but on the other hand your iinfasis on the interest of porting linux to theses devices...
->the great screens...
->usb host(input and STANDART peripherical)
i say standart because using an usb slave in order to make a conection for send and recive is possible but there are a lot of restrictions such as power... there is a section in the linux kernel that is called usb-gadget that can do this (that must have been used to get the pma400 mass storage compilant but it can also be used to make a serial link,network... between 2 computers or for developement boards) but that seems very complicated...

Zaurus - pdaXrom / Archos

Sashz,
Can you recomend good arm dissasembler, I looked on net for one but can't find good free one. Using dumpobj is a pain.

Didn't discover much last night.
Just if you have USB host connected when on blue debug screen it will sit there until you disconnect, and you can access HD wfrom host when on blue screen.
Interestring strings in ROM as you say. Same that say "duddudu" etc though might be button press combos, but no luck trying them.
Do you think there might be a terminal open somewhere ?

Use IDA - commercial Interactive Disassembler (look in p2p  )

If Archos connected to host during power up , that will wait disconnect and work as storage.
So in this mode you can restore corrupted fs or system.

Dunno about terminal software , there inside messages about USB2 port, so maybe its possible:) Anyway need disassembly and learn rom. Official french office says they cannot give us signature generator because security issues  So archos unlike linux and opensources i guess even if they released pma400 )

you said USB2 port
in the normal linux kernel there is a section that is called usb-gadget

USB is a master/slave protocol, organized with one master
host (such as a PC) controlling up to 127 peripheral devices.
The USB hardware is asymmetric, which makes it easier to set up:
you can't connect a "to-the-host" connector to a peripheral.

Linux can run in the host, or in the peripheral. In both cases
you need a low level bus controller driver, and some software
talking to it. Peripheral controllers are often discrete silicon,
or are integrated with the CPU in a microcontroller. The more
familiar host side controllers have names like like "EHCI", "OHCI",
or "UHCI", and are usually integrated into southbridges on PC
motherboards.

Enable this configuration option if you want to run Linux inside
a USB peripheral device. Configure one hardware driver for your
peripheral/device side bus controller, and a "gadget driver" for
your peripheral protocol. (If you use modular gadget drivers,
you may configure more than one.)

so maybe there is some info to find about HOW connect to this periferical side usb
-There is Serial gadget
-there is Ethernet gadget
-there is also a gadget filesystem

so mabe it work very similar to theses kernel drivers...

there is linux for:
-av300 (the most up to date is linav , not avos)
http://linav.free.fr/index.php
http://avos.sourceforge.net/


http://avos.sourceforge.net/index.php?a=hw
http://linav.athensmultimedia.com/wiki/ind...Chips_in_the_AV

-pma400
Qtopia and some comunity developement that is trying to port opie,gentoo...

so...
what is the hardware difference between
-av300
-others (av400,av500,av700,gimini...)
-pma400

is there a chance to port linux to the others devices???
i don't plan to buy one but they have some avantages:
-usb host on the av 500 and av700 => less input problems
-a lot of others advantages (compact, a lot of space, good screen...)

OpenZaurus/Opie/Qtopia / Ipk Frontend With Scripts

« on: November 28, 2005, 02:41:50 pm »

CONTEXT:
i want to make a frontend to the ipk packadge management that is not perfect under my system because:
-it doesn;t work very well
-there is soo much locations and confusions between the programs that want to install the ipk into /dev/shm or /progfs or /dev/loop/...
-not enough user-friendly

so mabe i'll need to rewrite the ipk package management...
 
QUESTIONS:
-is there already good ipk manager/frontend under qtopia?
-is there any easely programable api such as Xdialog under qtopia?
