Hi,

Recently I've bought a Asus RT-G32 (H/W B1) and I followed all the steps of wiki to upgrade it to DD-WRT but with no result.
I've been in Asus website and in the firmware page for this router I've noticed a specific and different firmware for the version RT-G32 (B1) (they write there that RT-G32 is different from RT-G32 B1).

After post in the Atheros WiSOC based Hardware sub-forum, a friend told me that the new Asus RT-G32 B1 comes now with Ralink hardware.

Does anyone know how can I install DD-WRT in this new RT-G32 B1 hardware version?


Thanks a lot

Since you are one of the first owners of this model you should start with uploading a high res photo of the internals.

The FCC photo is a bit blurred, the cpu seems to be an RT3052 but can also be the new RT3350.
What RAM chip is used, what flash chip?

A serial log telling what kind of bootloader is used (redboot, U-Boot ?) and the routers software id is also very helpful in order to get support for it.

Hi again,

First of all thanks a lot for your reply.

I will open the router and make a high res photo.

Regarding bootloader I think it's not redboot because I used putty to try to access it but always without result. But if you would give me some help to make a serial log I can do it (I just need some help because I'm not an expert on this).

About software ID it's in the Asus website (in RT-G32 firmware page). They have already there a specific firmware file for this version (B1).

If anything else is needed just ask that I try to put here.


Thanks

I downloaded the Asus GPL source code(RT-G32 Rev B1 GPL v2.0.0.5).

The SDK history is
Code:

Ralink AP SDK - History
Version 3.3.0.0


and the autoconf.h
Code:

#define CONFIG_USER_LLTD 1
#define CONFIG_VENDOR "Ralink"
#define CONFIG_PRODUCT "RT3052"
#define CONFIG_LINUXDIR "linux-2.6.21.x"
#define CONFIG_LIBCDIR ""
#define CONFIG_LANGUAGE ""
#define VENDORS_AUTOCONF_INCLUDED
#undef AUTOCONF_INCLUDED


I guess this hardware version B1 is RT3052 board.

Yes it is an RT3052.
The board has 4 holes for a pin header and it looks very much like a serial port connection.
3.3V on one of the outer pins, GND on the other sides outer pin and RX and TX signals on the 2 middle pins.
From the FCC photo it looks like there is silkscreen marking of the pin functions.

http://www.dd-wrt.com/wiki/index.php/WHR-G300N

Does it look like that?

If so, it may be very close to the WHR-G300N hardware.

Quite a few manufacturers are using a similar reference board design.

Finaly here they are the photos. They are not yet in high res but soon as I have again my camera I will make high res photos. But I think that this photos already give an idea of the new hardware.
If someone need more information, just ask.

Thanks a lot.

Still a bit blurred (or is it my old eyes?), the ram looks like Winbond 16MByte. W9812G6IH-6 ?

The flash chip is on the other side of the PCB, is it a 4MByte MX29LV320 ?

Your 4 pads for a serial terminal connection are clearly visible and marked, now you'll only have to connect a serial terminal there in order to log the boot sequence.

The voltage level is 3.3V so you can not connect it directly to a PC serial port, it needs level conversion.
I suggest you get a USB to TLL converter from Ebay or your nearest mobile phone shop, they convert from TTL 3.3V to USB and will appear as a serial port in your computer.

Known as Nokia DKU-5 (original type) but the clone CA-42 also works well, they are around $3-4 on Ebay.

Only 1 antenna?

Is this a Wireless-N 150mbps router?

Looks like it.

Does it have gigabit ports?

Hi again,

Yes only one antenna and I think no gigabit ports.

Regarding serial logs I think I can do it with a converter made by me based in a max232 (used to unlock an old ericsson mobile phone long time ago:) ). The connection to computer is serial but I have a usb/serial converter.
I just need some more help about the pinout of this router and the best software to make the log.

But current DD-WRT for Ralink RT3052 are support 32MB RAM with 4MB Flash. Is it possible to have a 16MB RAM version?

By the way..
Cool! This board PCB seems to reserve USB pinout. It may be able to mount a USB connector and some compoent to have usb functions.

I forgot to confirm that the RAM is Winbond W9812G6IH-6 (0948W).
On the other side of the board there is a (MX) 12G 25L32050M21. The photos are from back part of the board.

About router pinout to connect interface I was looking in wrong zone of the board. The pinout labels are there (gnd, Rx, Tx and Vcc).
I still need the other information I asked in previous post.

Thanks

Yea, I do NOT think you can flash the WHR-G300N build on this.

The WHR-G300N has 32MB of RAM, and with the non-vpn build, it still only has about 15MB free RAM left.

Brainslayer probably has to make a modified build to use less memory for this device.

I will try to make a serial log now. I have a RS232/TTL converter based in a MAX232 (used to unluck old mobile phones). Does anyone know if I can make the logs using this converter based in a MAX232 and and not in MAX3232?
One more thing. What's the best software to make the logs (for Windows Vista)?

Thanks a lot once more
