Title: Repartitioning 5600
Post by: Yasen on November 08, 2004, 09:34:54 am
Here (https://www.oesf.org/forums/index.php?showtopic=8199#) I found this:

Analysis of the previous message showed that the kernel seems to partition the MTD
If this is true can 5600 be repartitioned so all flash memory is mounted to "/"?

So far as I can tell, no.  The partitioning in the 5600 is reflective of the hardware I think.

This might be true but when starting oz there is line
Code: [Select]
Creating 3 MTD partititions on "Toshiba TH58512FT" so I think it isn't inposible. If I'm wrong please explain me why.
Edit:
According to Mr.Google "Toshiba TH58512FT" is 64MB NAND flash chip.

without grabbing my z, it seems to me that there are  2 chips in there. I guess you could make more small partititions. I think, though that the 64m can't be used for running programs, and the 32 can. That would mean either splitting up the storage in the 64 or using part of the 32 as storage.  Is that what you meant? I was thinking along the lines of 5500 style repartitioning to one big useable partitiion.
AF.

Sory byt my English is not very good.

I can't understand why it is so.

That is almoust what I was thinking about. As far as I know "/home" partitition is infact part of the RAM and so repartitition of 5500 is infact "increasing" the ram. This "increasing" is not real because this RAM is not used as RAM but as temporary srorage. Or atleast this is what I've understand from things readed here. My idea is to have all 64MB of NAND Flash as one partitition.

Hmmmm.. I think there are some hard limits on access to the 64m chip.  The fact that /home can't be used as swap might be a clue.

/home is the second paritition of the single nand chip.  To answer your question, yes, it can most certainly be repartitioned.

I dont think that it is inposible. I think it's not good idea to have swap on any type of flash.

Have you made any research on this. Can you give me some ideas where to look. Would be very greatful.

Do you mean repartitioning for data strage? or for program execution space?
You won't get more "ram" by repartitioning.if that is what you meant.

I can't understand why are you thinking that programs can be executed only from "program execution space". They can be executed from any type of Flash ram on Z. Data can be stored whereever you have write permicions not only in "data strage"

I've never said something like this. May be my English is very bad or maybe you don't like to read what is writen. After all I was asking someone who knows something on this topick. From all your post I can say you know less than me so please stop fluding this topick.

Marvellous. Let me know when you succeed.
My guess is that you will get a 64 meg partition and a 32 meg partition. I do not see a straight 96 meg partition (like somekinda flash lvm?). Certainly you will find a way to store programs on the 64 meg partition.
was that what you meant?

If so, wouldn't it be easier on your os (conf files and scripts that expect somepartitions to exist for example)  to use the second partition storage and just make symlinks to the first partition?

or do you mean that flash rom and ram are the same because of some special zaurus magic?
 
but enough of "flooding" your thread.
good luck

oops the ram isn't a partition. sorry.
