Topic: D-Link DSL-504T HW A1 ( old adsl router ) : 12 free GPIO PIN

The content of this topic has been archived on 4 May 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

I flashed it without adsl support because it's an adsl V1 routeur and i only want lan support.

Here are GPIO pins i've found :

Console Serial port :

Connector name on board : JP5

if you have the leds at right ( so the switch at left ) here is the order :
TX
NA ( not connected ? )
3V3
GND
RX

settings : 38400,n,8,1

OpenWRT info :

I've used trunk version ( Backfire should work also ) : openwrt-ar7-generic-squashfs.bin

I've used the tutorial from DSL-524T :  http://wiki.openwrt.org/toh/d-link/dsl-524t with this partition layout :

D-Link DSL-524T and OpenWrt

partition     Name          start                     end                     Description
mtd2     loader           0x90000000     0x90010000     Bootloader (ADAM2)
mtd1     linux              0x90010000     0x90086b80     Linux kernel
mtd0     rootfs            0x90086b80     0x903f0000     Read-only squashfs + jffs2 filesystem
mtd3     config            0x903f0000     0x90400000     Original firmware configuration
mtd4     rootfs_data   0x90010000     0x903f0000    

In tutorial you have to send this command :
quote "SETENV mtd0,0x90086B80,0x903f0000"
quote "SETENV mtd1,0x90010000,0x90086B80"

You must add this to avoid error 550 when flashing :
quote "SETENV mtd4,0x90010000,0x903f0000"

You have RX labelled twice and no TX. Also not clear which pads the serial labels apply to.
Otherwise great work!

Ah, just for clarity, the serial pads are under the label, with wires soldered on?

I reedited my first post with new pictures so that it's more easy to identify where is the serial port smile

I've ASUS AAM6030BI ADSL modem which is based on TI AR7 as well.
I gonna try to install.
Much appreciated.

Edit: It has only 2mb flash sad

Dear Flopstop,

when you said :
I flashed it without adsl support because it's an adsl V1 routeur and i only want lan support.

If I well understood you just use it as a switch. Is not it ?

If well how did you just set it to be used as a switch in place of a router ?
I ask this because I also have an old Philips Blue Model SNA6600/18 : http://wp.bioss.net/technical/philips-a … -pstn-blue

Then I though to use it as a switch in place as a modem/router

Sincerely thanks.

Hi,

I use it not as a switch but you can do it, I think all that you have to do is to set a fixed ip adress on the router, disable dhcp if there is one, and it will work as a switch.

The discussion might have continued from here.
