cd , ls , iwconfig etc. not working in OpenWRT

Did you take OpenWRT directly from the trunk; so you have not applied either the kernel patches on this site, or the enhancements to the build environment?

As far as I understand there is no support for building CHK images in the OpenWRT trunk. So I am guessing you did this yourself? Is the jff2s correctly aligned?

Yes I took it from the trunk and also I have applied the kernel patches ....
I build the chk image myself using the packet tool ....
How can I check if jff2s is correctly aligned .... ???
Moreover I would like to mention that hang happens if we press tab after giving some commands partially like "iwconfig" .... and for some commands like ls or chmod even if I give full command without using tab ...the hang happens ...

Ok well the correct magic for OpenWRT is in this download; I should point out I am in the process of a) updating that, and b) merging things into the OpenWRT trunk. So any test reports greatly received.

You need to align things ok a 64k boundry. The following snippit is how I use the TRX tool to achieve that (using the one from OpenWRT). This is from target/linux/brcm-2.4/image/Makefile.

trx -o $(BIN_DIR)/openwrt.trx -f loader.lzma \
    -f vmlinux.lzma -a 1024 \
    -f $(KDIR)/root.$(1) -a 0x10000

Thanx for the input .... OK let me try this .. meanwhile If I get any further observation I will let you know ... 

One thing I have observed with OpenWRT is that when I flash the board with openwrt for the first time and give an ifconfig command , I get the following output :

With ifconfig -a I am also able to see wl0 interface .
Now I want to configure my board as a client bridge and for that purpose I am changing some nvram variables as follows :

root@OpenWrt:/# nvram set lan_proto=static
root@OpenWrt:/# nvram set lan_ipaddr=192.168.1.1
root@OpenWrt:/# nvram set lan_netmask=255.255.255.0
root@OpenWrt:/# nvram unset lan_gateway
root@OpenWrt:/# nvram unset lan_dns

root@OpenWrt:/# nvram set wan_proto=static
root@OpenWrt:/# nvram set wan_ipaddr=192.168.10.133
root@OpenWrt:/# nvram set wan_netmask=255.255.255.0
root@OpenWrt:/# nvram unset wan_gateway
root@OpenWrt:/# nvram unset wan_dns

root@OpenWrt:/# nvram set wl0_mode=wet
root@OpenWrt:/# nvram set wl0_infra=1
root@OpenWrt:/# nvram set wl0_ssid=home_test
root@OpenWrt:/# nvram commit
root@OpenWrt:/# reboot

And after reboot if i give an ifconfig command it shows nothing and with ifconfig -a I get the following output :

root@(none):/#
root@(none):/# ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:1E:2A:07:AC:72

Could any body please tell me if I am doing anything wrong here or is it a problem with OpenWRT and also why do I see the command prompt as
root@none instead of root@OpenWrt .

Thnx in advance,

Ok well the first thing is that OpenWRT does not store its config in nvram. The root dir is mounted using mini_fo; basically a COW filing system. This means you can edit just about anything and it gets stored for next time. So the file you wanted to be editing was /etc/config/network!

Second the "root@(none)" is very telling. This could be a number of things but basically some bit of the filing system has not been mounted correctly. Here is the output from mount:

rootfs on / type rootfs (rw)
/dev/root on /rom type squashfs (ro)
none on /dev type devfs (rw)
proc on /proc type proc (rw)
tmpfs on /tmp type tmpfs (rw,nosuid,nodev)
devpts on /dev/pts type devpts (rw)
/dev/mtdblock/4 on /jffs type jffs2 (rw)
mini_fo:/jffs on / type mini_fo (rw)

I would recommend reading the OpenWRT Docs, they are not complete but will most defiantly help!
