Hi,
I have added new partitions to nand, named "filesystem2" and "data2", I need a reliable way to perform filesystem updates and don't want to update a mounted filesystem.
<5>[ 0.190000] Creating 7 MTD partitions on "nand_davinci.0":
<5>[ 0.190000] 0x00000000-0x00300000 : "bootloader"
<5>[ 0.190000] 0x00300000-0x00500000 : "params"
<5>[ 0.190000] 0x00500000-0x00900000 : "kernel"
<5>[ 0.200000] 0x00900000-0x02100000 : "filesystem"
<5>[ 0.200000] 0x02100000-0x02300000 : "data1"
<5>[ 0.200000] 0x02300000-0x03b00000 : "filesystem2"
<5>[ 0.200000] 0x03b00000-0x10000000 : "data2"
in the /dev folder I can see /dev/mtd0 to /dev/mtd4, but can not work out how to get mtd5! and mtd6!

Can someone please point me in the right direction, I just need to be able to write to the new partition /dev/mtd5 and copy my new filesystem (ipnc_*.squashfs)
Thanks for any help
Nick
