Create remove resize MTD partitions at runtime...is it possible?

[Ravi Vasarla]

Hi,

What do you mean the system up? does it means the MTD driver is loaded, then you want to change the mtd partition? in that case it is not possible to change the mtd partitions details.
 As the entire partition is mapped by the respective MTD driver only once, so once it is configured as read only then it will only change by MTD driver modification.

Regards,
Ravi

Subject: Create remove resize MTD partitions at runtime...is it possible?

Hello,

I'm trying to find out whether I can create and MTD partition after
the system is loaded. I'm running custom embedded linux on arm9 custom
board, the four MTD partitions are defined in cmdlinepart and the
first one is marked as read-only. The concrete question is whether
it's possilbe and what should I do to create mtd4 that overlaps mtd0
and mtd1 dynamically while the system is up and running (in ramdisk) ?

I've researched the topic and mtd source tree and the best I could do
is create new MTD within the boudries of existing one (this also could
solve my problem, but does not overrides the read-only attribute on
mtd0). Any help would be greatly appreciated.

Best regards,
Hristo Yankov
