Bekijk de volledige versie : Trying to replace Busybox
The original WL700gE Busybox is v1.0.0-pre2. I replaced it with v1.0.0.
HDD is mountig as expected in shares/MYVOLUME1/MYSHARE1, but USB flash-drive causes an error:
# Disk (8, 64) added.
Failed trying to read the Disk Header for /dev/scsi/host1/bus0/target0/lun0/disc: No such device or address

Error on disk (8, 64).
Notifying user: Error: Disk `Foreign Disk 1' is Broken.
when replaced with v1.1.3, the HDD also does not mounts. Mount command responds with error Invalid argument
could it be that Broadcom has modified busybox? could it be old glibc? any other ideas?
Are you sure you want to mount the whole usb flash drive not a partition on it?
Does it have partitions on it?
Then you should use (e.g.) mount /dev/scsi/host1/bus0/target0/lun0/part1 ..... instead.

Thanks for pointing out this, but then there is a bug somewhere because often when I plug my USB flash-drive, it is not mounted. On the serial console there is an error message:
~ # Disk (8, 0) added.

it is often for busybox v.1.00, but not for v.1.00-pre2 (original for asus)
What does this mean?:

What does the mount command is trying to read from Disk Header ?
When you try to mount the whole device ....../disc and the drive contains partitions, it will not read the partition header but the master boot record of the disk.
What does "fdisk -l /dev/scsi/host1/bus0/target0/lun0/disc" say?
If you don't have fdisk on the router, you can connect it to a desktop pc...
I think, the problems are because some USB sticks are formatted without the use of a partition, and others do use partitions.
If you don't have data on the stick, you could format it (without partitions) with "mkfs.vfat /dev/scsi/host1/bus0/target0/lun0/disc" on a linux pc.

fdisk output is the following

from what you are saying I assume that it is actually a not correctly cretaed feature from asus and it could be fixed? there is a function hotplug_usb_mass(char *product) in file rc.asus/services_ex.c
Busybox has a lot of options to configure :-)
Are you sure, you did everything right?
I'm not familiar with the WL-700gE, I use OpenWrt Kamikaze on my WL-500gx :-)
Are you able to mount the usb stick manually, with part1 instead of disc?

Yes, I can mount USB disk manually. I can say that with busybox form asus source tree everuthing works greate, but there are problems with Busybox v1.00 - USB not always mounts. And with newer Busybox releases HDD also does not mounts.
I'm pretty sure I configured Busybox the same as Asus did. The only thing is that Asus build options has "bogus-config-error-" as cross compiler prefix whereas I have "mipsel-linux-". otherwise it wont compile
there is another copy of busybox in /apps/bin if you try to launch it, there is an error:
# /apps/bin/busybox
/apps/bin/busybox: error while loading shared libraries: /apps/bin/busybox: symbol vprintf, version GLIBC_2.0 not defined in file libc.so.6 with link time reference
HDD is mounted inside rc binary by calling /sbin/init (witch is symlink to rc) and there is no source code for it.
when you attach or remove USB disk, hotdiskadd or hotdiskremove code is launched. They are symlinks to the same rc binary:
# ls /sbin/hotdisk* -l
lrwxrwxrwx 1 root root 2 Nov 27 16:38 /sbin/hotdiskadd -> rc
lrwxrwxrwx 1 root root 2 Jan 1 1970 /sbin/hotdiskremove -> rc
It seems that Broadcom, not ASUS has not released rc source :(. Why it is even worse, is that the original ASUS code has bugs and my USB disk is not always recognized:(:

There are actually two versions of rc in the source tree. The first one, witch is used by default, is in apps/mipsel/install/rc/sbin, another - newer is in apps/mipsel/install.rc3/rc/sbin and is never used. Why is it here?:(
If Busyboxis replaced, something strange happens, and HDD is not mounted by issuing command:
mount /dev/se/2 /shares/MYVOLUME1
Could it be that glibc or any other librariy is old and therefore mount command does not work properly?
More reasons to switch to OpenWrt ;-)
People should not try to enhance/bugfix the original Asus firmware, but try to get OpenWrt running on this device...
Then you could really do what YOU want.

I completely agree with you but it will take some time. OpenWRT is working on it: http://forum.openwrt.org/viewtopic.php?id=4883&p=2
I' more programmer than reverse engineer.
