jffs2 partition on a TQM860L???

jffs2 partition on a TQM860L???

[Steven Scholz]

Hi there,

I want to use JFFS2 as root fs on a TQM860L with 8MB flash.
This flash is seperated into two flash banks each 4MB.

(How) can I define one big jffs2 partition (in
./drivers/mtd/maps/tqm8xxl.c) that contains sectors from both flash banks?

Thanks a million,

Steven

Just use a more recent version  of  the  MTD  code,  for  example  as
contained  in our linuxppc_2_4_devel tree. It will automagically join
adjacent flash banks into one MTD device.

Oh! I see. Apparently while updating to a newer MTD version this file
was overwritten with an older version!

Thanks again!
