Topic: Installing OpenWRT micro on WRT54GS v5.1

For installing OpenWRT on Linksys WRT54GS v5.1, documentation says to follow these instructions:
http://www.bitsum.com/openwiking/owbase … RT54G5_CFE

but those instructions are for instaling DD-WRT micro.
Should I follow the same procedure also for installing OpenWRT micro?

Re: Installing OpenWRT micro on WRT54GS v5.1

I wouldn't.  OpenWRT, as far as I know right now, isn't supported on anything G 5 and above.  There's a chance you could brick your router, and the DD-WRT micro has been tested for those routers.  I don't know of anyone successful in installing OpenWRT micro on them.

Maybe someone who is reading here has done it, though.

Re: Installing OpenWRT micro on WRT54GS v5.1

too late... I did it... I flashed OpenWRT micro...

This is the firmware I flashed:
http://downloads.openwrt.org/whiterussi … uashfs.bin

results:
the "power" led blinks continuously, if I ping 192.168.1.1 it answers correctly, but I can't login via telnet nor via ssh.

What can I do? Throw the router out of the window?

Please somebody help me....

1.5 hours between your post and me replying.  You should have waited.  Probably the only way to recover now is follow the instructions on reloading the VX Works firmware and hope.  You'll have to do it with tftp, and I'm not even sure that will work if boot_wait was set to off.

Past that, a JTAG would probably be your best bet.  I'm not even sure if that will work.

Re: Installing OpenWRT micro on WRT54GS v5.1

Openwrt  can be installed on it - if you use the imagebuilder and are very selective about what you do and do not include. You have less than 64k on the squashfs with the micro image. dnsmasq can be removed and replaced with nas (if you just want to use it as a bridge)

ok, so if it can be installed, and considering that I installed the squashfs version, the question is:

Why It doesn't work? Maybe I used the wrong procedure? How can I login on 1st bootup when installing OpenWRT micro?

Re: Installing OpenWRT micro on WRT54GS v5.1

Your router isn't bricked. You don't need JTAG.

You tftp'd the wrong image. You must tftp the generic TRX image, not the specific wrt54gs one. Otherwise your router rejects it and just sits there at boot waiting for you to transfer a valid firmware. Which is what your router is doing.

You will be without a webif in openwrt micro by default. Like previously said, you need to build your own image for it to be moderately useful.

It doesn't sound like you are prepared to deal with what you'll encounter even if it was flashed.

To flash back dd-wrt micro, just tftp dd-wrt micro generic.

Re: Installing OpenWRT micro on WRT54GS v5.1

I don't know...
Actually at home I use an old Pentium 2 box as firewall, with Debian installed on it, NO web interface, configured "manually" with iptables and dnsmasq.

The packages that I need to do the same things on the WRT are included in the OpenWRT micro distribution... so I think it will be ok for me...

If the WRT is just waiting for a new firmware, I just ask which image do I have to reflash on it...

This trx:
http://downloads.openwrt.org/whiterussi … uashfs.trx
Is the image you are talking about?

So chances are:
- install the generic OpenWRT micro trx
- install DD-WRT
- install custom builded OpenWRT

right?

You gotted right, I advice you to follow http://wiki.openwrt.org/ImageBuilderHowTo and remove anything that you aren't gonna use. I also advice you as you do this, to include any new configuration file or even a modify one, cause using the WAP54G, more o less same specs, even when I got a read/write filesystem, the space got out very quickly.

Re: Installing OpenWRT micro on WRT54GS v5.1

thanks for the answer.
Actually I have installed the standard openwrt-brcm-2.4-squashfs.trx, just to be sure that the router wasn't bricked, and it works.
I can login via telnet.

Now I'll see which packages do I need and build a new custom image, then I'll reflash it...
OpenWRT is rock 'n' roll...

Re: Installing OpenWRT micro on WRT54GS v5.1

Cool, glad you got it booting. The TRX vs. BIN is an easy mistake, as DD-WRT's firmware images are not named in the same manner (it's generic is named .bin).

There is a lot of interest in OpenWrt for micro devices. I would like to work on this, but already have too many projects in this community I'm working on. I would like to see there be a concerted effort to develop a good micro OpenWrt firmware (please, we need not hear from those who don't like the idea ;p).

Re: Installing OpenWRT micro on WRT54GS v5.1

Excellent...in this case, I'm glad I was wrong, that's for sure.  I hate to hear of anyone bricking a router, even if it's the crappy v5.0 and up of the G/GS

Re: Installing OpenWRT micro on WRT54GS v5.1

In case someone needs it: just made a nano-image for use e.g. with 2Mb-Flash devices. Be warned: this is really _very_ barebone. It's generated with the freifunk-KIT (similar to OW image-builder) which has a new switch for this. Flashable image is here:

http://styx.commando.de/sven-ola/freifunk-nano.trx

Some techno babble:

- 10 flash pages free on wrt54g-v5 for JFFS2
- Which means: 512 kb compressible r/w space
- mini_fo is used, ipkg's can be installed via "ipkg update..."
- all config via nvram, no iwconfig (use "wifi up")
- no firewalling, no dropbear, no dnsmasq (only udhcpd)
- Freifunk uses iproute2, so no "route" nor "ifconfig". Use "ip"
- No web ui, only telnet. Failsafe and autoformat supported.
- Freifunk does not support WEP nor WPA
- Same kernel, uclibc is compat to Whiterussian/RC5
- Which means: You can install RC5 ipkgs.

Kernel: 465k, RootFS: 588k, Jffs2: 2688k/0x2a0000, TRX: 0x107000

Be warned: This is nothing for beginners. If you don't know how to TFTP do not use it. Here's a live snapshot (that device has 4Mb/16Mb):

Re: Installing OpenWRT micro on WRT54GS v5.1

If I download the Image Builder and start using it and selecting packages to make my own firmware, how can I assure that the firmware I am making is micro and not standard?
Are there any mechanisms to set this?

And another question: what's the difference between Image Builder, Buildroot and Buildroot-ng?

Re: Installing OpenWRT micro on WRT54GS v5.1

The Image Builder is generated out of the buildroot and generates images from package lists without actually compiling anything. 'micro' is one of the lists of it, so running an image builder make will give you the micro image.
Buildroot is the name for our build system, which downloads, patches and compiles the packages.
Buildroot-ng is the build system rewrite for the upcoming 'kamikaze' version (currently a developer tree in svn only).

See warning about fix today, else your router will brick.

yeah thanks I've red it, and I was wondering if I can obtain a fixed image using Image Builder or if I can obtain it only by using Buildroot...

Or maybe can I "manually fix" by canging that line in the file /etc/init.d/S05nvram ??

Re: Installing OpenWRT micro on WRT54GS v5.1

I have almost the same device: WRT54GS v5.0

ALL:

Could you pls take a look at http://www.dd-wrt.com/phpBB2/viewtopic. … 4398#74398.

Main brief summary of my questions:

1) Is anywhere custom builds repository for openwrt MICRO?
2) Is it possible to get from openvrt the same as dd-wrt MICRO by functionality but with nfs mounting in addition or with samba client in addition? purpose - get network mounting. It will resolve problem with storage. and it is reasonable in case of home using, because when u r using Internet t least 1 PC is used also, so add space will be always available
By my opinion, for simple home using it culd be achieved with removing upnp, wep but leaving wpa,  if still no space - then also dnsmasq, local dns

WRTOpener

Hey Bud.  I am glad that you got your router running, I too have a WRT54GS-V6 I manage to put DD-WRT on it, now I would like to re_flash with Openwrt.

did you build your image?
is it running?

I am little checkin; I don't like to see my power led ding dong.

Re: Installing OpenWRT micro on WRT54GS v5.1

I would like someones input on this. I built a small version of Openwrt for the 5.1. It flashed
correctly. But it seems it doesn't get me all the (limited...) memory this device has on board?!
My image size is just 1052672 bytes. Here's what I get though:

Creating 5 MTD partitions on "Physically mapped flash":
0x00000000-0x00040000 : "cfe"

mtd: partition "rootfs" doesn't start on an erase block boundary -- force read-y
0x001f0000-0x00200000 : "nvram"

This differs quite a bit from the output from sven-ola above. Seems I get only half the rom?
I you know what could be causing this I'd like to know!

Re: Installing OpenWRT micro on WRT54GS v5.1

Hi,

I try to install DD-WRT or OpenXRT on WRT54GS v5.1 and i found this links :

http://www.bitsum.com/openwiking/owbase … 54G5%5FCFE
http://www.scorpiontek.org/portal/content/view/27/36

But I can't flash the firmware vxworks_prep_v03.bin. I've got a "Upgrade are failed!" message.
The router have the Firmware Version: v1.50.5, Jan. 20, 2006.

Can you help me ?

Doude.
