Okay, then I will try to post the NVRAM settings tonight. But I must admit, that I already changed a couple of things and was playing around with the network devices :? So the settings might be not the same like right after installing OpenWRT, hope that does not confuse you. Or should I better reflash the image, reboot and dump the original stuff? I wonder what the post-install of OpenWRT does with the original content of the NVRAM...

Cheers,
BratMaxxe

OpenWrt itself won't change any variables. But sure, a factory clean one would be better usable.

There we are...

The settings posted yesterday are slightly modified by me 8) In case I messed something up, here comes the original image of the NVRAM area extracted from the latest firmware image by siemens...

Cheers,
BratMaxxe

This isn't enough for real (as these aren't all the variables). Please reflash the factory firmware, click on "restore defaults", flash openwrt without the diag module, and paste the nvram show again. I'm almost sure, what are the problems, but want to be sure, that the fixes will work on the new units out-of-the-box (with the factory variables).

Okay now here is what I did, because the original fw did'nt like my mess either... 

1. Under OpenWRT erased the NVRAM settings first:
# mtd erase nvram
# reboot

2. Flashed the siemens fw and accessed the router via http. No reset to defaults option available, but since I erased the NVRAM with the previous OpenWRT I was able to access the device via eth again. -> dump NVRAM settings to file 'NVRAM Siemens.txt'

3. Reflashed OpenWRT without diag module. reboot. No eth available. -> dump NVRAM settings to file 'NVRAM OpenWRT.txt'

Hope this helps,
BratMaxxe

I'm interested in a solution, since I have exactely the same model as BratMaxxe.

Okay, IMHO I know the problem. I make an image for You to try it out. BTW, if You have a higher resolution internal photo of the unit, it would be really helpful.

BratMaxxe: please post a dump of mtd0, too.
Thanks.

Hi Kaloz, Hi BratMaaxe, I directly joint the openwrt forum after I read this nice thing about the SE505 router and surprise, surprise I am an owner of this very popular dsl router in Germany. I bought them via ebay as a cheaper unit then the linksys ones. My model is the same like BratMaaxes with the nice rebooting loop.
Kaloz did you need still the high resolution photos from the siemens unit? If so please give me a short reply and it would be a pleasure to provide them.
Many Thanks to all

I'm just compiling the image for You to play with, I will post it later tonight/tomorrow
For the pictures, I'm not in need of them, but they won't hurt. (maybe someone will need them)

O.K. I will make the pictures tomorrow at work, because I have no stand for my digicam at home.

Here we are, maybe the SE505 MK2 PCB images are helpful for the hardware modding fraction. I called my version of the SE505  “MK2” and you will find attached the so called LowRes Images (<= 2MB each) of the routers PCB. If any one need the HiRes versions (< 47MB each), then we have to find a suitable distribution way.

Something is going wrong, I am not allowed to upload the files… :?

Kaloz, were you able to build the image. I am in need of this image also. thanks for your efforts.

Just to keep the topic warm...

Yeap! Did'nt hear anything from Kaloz since ages. He's probably busy or on vacation  8) I have'nt had a minute to spend on my unit either. So there are still a few issues to solve:

1. Get the diag.o module working with the siemens LED's (uncommenting it out in your own build is a fix).
2. Get the NVRAM sorted so that ethernet works out-of-the-box.

BTW: I got ethernet running on my unit after erasing the original NVRAM content (OpenWRT is just using the settings as they are and I assume that Siemens FW is using some of the variables in a different way).

:?

I think we are pretty close, but somebody needs to put all the required patches and work-arounds to main trunk...

Regards,
BratMaxxe

I've checked your cfe image and it appears, the real MAC address is not stored anywhere. Have you tried putting Siemens firmware back to check that it restores correct MAC?
From the nvram dupms above it appears, that it does not...

Sorry, I'm quite busy due to my work nowadays.. Anyway, stay tuned, I will post a test image this weekend for sure..

There is no reset to defaults option available in the siemens fw, at least I could'nt find any

So I decided to erase the NVRAM under OpenWRT first, then put back the siemens fw (no clue whether the siemens stuff is writing the MAC address to the right spot) BTW: Why is there a need to store this MAC in CFE? Does OpenWRT rely on this?

Made the dumps and put back OpenWRT. Right now my unit is accessable via eth and it looks pretty good, altough I have'nt had time to configure it for use in my environment properly...

I'd just like to run in Access Point or Bridge mode and don't need the router stuff. Anyway I think there is to less memory for that use, just 3Meg's left in opertion 

Any firmware requires unique MAC address. It should be stored somewhere. It's also possible, that it was stored in the nvram only, which you've erased. Other units have correct mac address either in the embedded nvram (fallback in case nvram is invalid) or special dedicated area inside the bootloader.

Flash Siemens firmware and check MAC address by examining arp cache after pinging your unit. I'm wonder if it would be able to restore it.

After erasing the NVRAM with the following command:

#mtd erase nvram

the mac adress of the router is set to 00:90:96:00:00:00 in OpenWRT and after flashing the original FW to....

seem's that the number from the sticker on the back is gone and replaced. anyway it's just a f.... number and I don't get the point 

Don't get me wrong, but I'm a bit sick and tired of all those boring tests without any progress or support/supply from your side....

Is there something that someone without access to the serial console could do?

What's going on now? Is there hope that we'll get OpenWRT on this router or can we forget it?
