Hi.

How can I backup WRT54GL with 2.6 kernel to flash other WRT54GL?

Should I use /dev/mtdblock1 ? Is it necessary to remount any file system in read only mode (like this: http://forum.openwrt.org/viewtopic.php?id=11573)?

Regards.

Just curious,

Why are you using 2.6 with a WRT54GL?

Does it not work the same way as WR?

dd if=/dev/mtdblock/1 of=/tmp/backup.trx to backup
mtd -r write backup.trx linux to write

I just wanted to have 2.6 kernel. I use this boxes as OpenVPN clients and don't need wifi.

There is no /dev/mtdblok/1 device file:

# ls -1 /dev/mtd*
/dev/mtd0
/dev/mtd0ro
/dev/mtd1
/dev/mtd1ro
/dev/mtd2
/dev/mtd2ro
/dev/mtd3
/dev/mtd3ro
/dev/mtd4
/dev/mtd4ro
/dev/mtdblock0
/dev/mtdblock1
/dev/mtdblock2
/dev/mtdblock3
/dev/mtdblock4

Is /dev/mtdblock1 the same as /dev/mtdblock/1 ?
