Hi,

I try to run OpenWrt on Buffalo WBRG54.
i successfully flashed the ap but i can't create the jffs filesystem.
When i run /bin/firstboot,  nothing occurs.

I suspect an mtd/partition problem.
I use CVS version of OpenWrt.
I try Sweasoft Firmware, it works normaly.

Here is my dmesg logs :

Check what the following output is:

mtd unlock OpenWrt
mtd erase OpenWrt
mount -t jffs2 /dev/mtdblock/4 /jffs

Here is a result of the cmd :

@(none)# mtd unlock OpenWrt
Unlocking OpenWrt
OpenWrt: No such file or directory

@(none)# mount -t jffs2 /dev/mtdblock/4 /jffs
mount: Mounting /dev/mtdblock/4 on /jffs failed: Invalid argument

Any clue???

Finaly i solved problem with my WBR-G54.

I just changed the kernel_args :

from :

kernel_args=noinitrd console=ttyS0,115200 root=/dev/mtdblock2 panic=1

to:

kernel_args=root=/dev/mtdblock2 rootfstype=squashfs init=/etc/preinit noinitrd console=ttyS0,115200 panic=1

I just had exactly the same problem, thanks a lot for the info! Also to help out any super n00bs (like myself), to change the kernel_args, you just need to change the setting in nvram like this:

nvram set kernel_args="root=/dev/mtdblock2 rootfstype=squashfs init=/etc/preinit noinitrd console=ttyS0,115200 panic=1"

Thanks a lot, this helped me too. For us super-newbies, don't forget to nvram commit and reboot as well... wink

The only other problem I encountered with my WBR-G54 was that wlconf isn't there anymore. I suppose this is documented somewhere, but after the wl0_* variables are set, wifi eth2 down && wifi eth2 up does the trick. Remember to enter wl0_key1 in hex (search google for a calculator if necessary). iwconfig behaved somewhat strangely, iwconfig eth2 enc s:key (passing key in ASCII) didn't seem to be acceptable.

Windows 2000's tftp command was enough to pass the TRX image to the AP. After plugging power, wait half a sec so that the diag led turns off before hitting enter on the put command. I used openwrt-brcm-2.4-squashfs.trx since White Russian's readme file recommends squashfs.

Should I be bold enough to update the Wiki page? http://openwrt.org/OpenWrtDocs/Hardware/Buffalo/WBR-G54

There really shouldn't be any need to set kernel_args since the defaults are compiled into the kernel. If you set kernel_args and we change them then it'll just use the old value from kernel_args, which is perhaps the problem in the first place.

mbm, not sure what you mean. After I had done the tftp transfer and some waiting, I logged on to the WBR-G54 and the log resembled Genoa's quite closely. Nothing seemed to be mounted and even /proc was at least partially missing. After setting the kernel parameters above, remembering to 'nvram commit' and rebooting the WBR-G54 was fine.

Just now, White Russian seems to have segfaulted. I was doing a backup via the WLAN interface and simultaneously downloading w2ksp4 on the LAN. The transfers are still on, but trying to log on to the device will result in multiple 'Aiee, segfault, perhaps you should report this to a developer' error messages. Unsure on how to report the exact problem though - I have ample time during the following few days and can gladly help in debugging, if necessary. I've got two WBR-G54's over here.

(After a bit of waiting while writing this post, the problem seems to have disappeared. The following SSH login still yielded a 'segmentation fault' message, but now everything seems to work fine again. Nothing about the incident in the log, and all processes seem to be running fine. Uptime normal.)

The discussion might have continued from here.
