Anyone working on Sig3 Linux?

that would be... me

YES!

so can you write up a letter please?

post it here and we will modify it if needed

then you send it

Okay, I can write, but I would much rather translate from English to Japanese.

So what do we need to know?

Does anyone have a list of the specs required to make linux work?

John

Don't know how useful this is, but from a translated Korean webpgage:

I think it's safe to say it may be a Imageon 4200....

the 4200 is the same as 3200 but has ability to use 8mb external ram (3200 doesn't IIRC)

John

PS I also wonder if the flash info will help us make this useable?

what do you mean, putting programs in there?

we've known the address for it, but the model (STMicro M29W320DT) is new to me.. try to find datasheets on it.

http://www.datasheetcatalog.com/datasheets_pdf/M/2/9/W/M29W320DT.shtml

Click on link

This may be the stupid question of the day... but here goes anyway....

That spec sheet makes it sound like the bootloader for the Sig3 may be on the Flash portion...

If this is true, and we can find a way to flash a new bootloader, is there any CE bootloader or way to tweak bootloader, so that it can load/run a CE os from a CF (or SD card)?

Now bear with me and my silly question. If we can does this mean we could store a version of CE on a storage card and have the sig3 run it's OS from there as if it was internal rom? would this open up the possability of psudo custom roms for the Sig3 and not limited to 32Mb? It would also mean we can change versions of files to make things run or replace programs with the english version rather than just the MUI (I think the problem with the HPC2000 office was a dll that required changed had to be in rom)

Silly question over....


Sorry... Silly question mode back on.

My other thought... Which is a bit more extreme.... Could we replace the std rom chips with flash rom or just a rom socket and std rom replacements same as original but with pins designed to go in the socket? For the 2nd option it isn't as good but we could at least use an external rom programmer to write custom roms onto the chips before popping in the socket.

If someone is experienced with external rom programmers and rom chips in general can they let me know if this seems like a workable idea as I have a Sig3 without screen I was going to keep for spares but would happily sacrifice it (if it all went wrong) to try this out...

All done now....

See! I told you it'd be a silly question

no, sorry, where did you get the impression the bootloader is in the flash rom? it is not.


no idea on replacing the chips, wait for Jax with that one depends if we can find a flash rom chip with the right specs

I though the words "BOOT BLOCK" in the data sheet ment it was designed to hold boot information.

As I say I am happy to get some chips and sockets soldered in place of the std roms. Either flash, or if there is some reason flash won't work (or fit) then a replacement part that is the same as original but socketed as opposed to surface mount.

Hopefully Jax can point us in the right direction.

If I can get parts I will do this... Of course I'll then be bugging you about how to build custom roms (after using your tutorials though)

John

well, i didn't look at the datasheet yet, can you quote that part ...?
anyway this flash is at 0x0c000000 for the sig3 so definitely not a "boot block". and i've seen the dumped contents of it already.. no bootloader, sorry

this rom replacing would be utterly cool
yes custom roms definitely and maybe updating to cenet 4.2 etc

Or maybe even CE5 or 6 (does the XDA not use same GRFX chip and CPU? so at least some of the drivers must exist). But then maybe we need more than 32Mb for that. Are there enough address lines on Sig's chips to put in more rom while we are at it?

4.2 would be great as at the very least we get WPA, Hidden SSID and HPC2000 office back

It's not even as far as the datasheet. If you follow the link the bit of text that describes the product mentions it.

"32 MBIT (4MB X8 OR 2MB X16 BOOT BLOCK) 3V SUPPLY FLASH MEMORY"

I had realised you had already dumped it as I had found the memory address in the registry. Just wondered if we had managed to get all 4Mb or if there may have been somthing else we didn't get.

The address's I supplied were "CE Update" entries in the registry, so concivebly, I had thought it possible it may not have been 100% of the flash between the two values we used.

Still it makes no odds if I can solder in flash or chips with a programmer.

I take it Monica is thinking if this can be made to happen and works "I'm 2nd in the que"

CE6, noo, would need to rewrite all drivers. CE6 isn't even out for WM either (WM6 is *not* CE6, it is based on CE5).

we got all 4MB yes, sorry, don't dream. i also dumped the nonflashable rom and the bootloader is there.

i don't even remember what addresses you supplied other than the start address which is the only one i used to dump it (giving 4MB as the size).
