|
I have a Buffalo WZR-600DHP2 with DD-WRT r43334 just installed.
I have activated the JFFS flash partition, and I see now:
Code: | root@WZR600DHP2:~# df -h
Filesystem Size Used Available Use% Mounted on
/dev/root 23.8M 23.8M 0 100% /
/dev/mtdblock/6 55.0M 1.5M 53.5M 3% /jffs
/dev/sda1 940.3M 27.2M 864.6M 3% /opt |
It seems strange to me a partition size of only , as long as this router is supposed to have 128MB Flash (and 256MB RAM), as researched: https://oldwiki.archive.openwrt.org/toh/buffalo/wzr-600dhp2 .
In order to compare, I am checking my Mikrotik RouterBoard RB951Ui-2HnD (128MB Flash ROM too) with OpenWRT v18 installed:
Code: | luis@OpenWrt:/$ df -h
Filesystem Size Used Available Use% Mounted on
/dev/root 2.5M 2.5M 0 100% /rom
tmpfs 61.1M 768.0K 60.3M 1% /tmp
/dev/ubi0_2 102.8M 55.1M 43.0M 56% /overlay
overlayfs:/overlay 102.8M 55.1M 43.0M 56% /
tmpfs 512.0K 0 512.0K 0% /dev |
As can be seen, it detects , much more close to the real 128MB real size.
Is there any error here? Why DD-WRT only sees about half of my ROM in the WZR-600DHP2? |

Here you have, for the Buffalo DD-WRT:
Code: |
~# cat /proc/mtd
dev: size erasesize name
mtd0: 00080000 00020000 "boot"
mtd1: 00160000 00020000 "nvram"
mtd2: 01f00000 00020000 "linux"
mtd3: 01d60000 00020000 "rootfs"
mtd4: 01f00000 00020000 "linux2"
mtd5: 01d60000 00020000 "rootfs2"
mtd6: 03700000 00020000 "ddwrt" |
It seems that 3700000hex equals to about 60MB .
And, in order to compare, the output of the Mikrotik RouterBoard:
Code: | $ cat /proc/mtd
dev: size erasesize name
mtd0: 00040000 00020000 "booter"
mtd1: 003c0000 00020000 "kernel"
mtd2: 07c00000 00020000 "ubi" |
This one shows, indeed, 7c00000hex , that is close to 120MB . |
