Help on MTD Partitions.

["Ramgopal Kota" <rkota@broadcom.com>]

Hi,

 

I am facing a problem with MTD partitions with linux 2.6.

I have a Spansion Flash of 8MB. where the number of erase regions are 2 ,

 

1st erase region has 127 64KB sectors

2nd erase region has 8 8KB sectors.   ( This is at the end of the flash)

 

I want to create 4 partitions.

NAME  --  SIZE

BOOT  --  128KB.

OS      --  2MB

JFFS    --  (8MB - 8KB)

DUMP   --  8KB

 

Kernel prints a error message that "JFFS Partition is read-only".

Can a partition span across 2 various erase regions ?

(I see that there is a check for the same in the mtdpart.c while adding a partition.)

 

Is there any work-around using MTDPART_OFS_APPEND & MTDPART_OFS_NXTBLK flags ??

Any help is highly appreciable ??
