Introduction

It's a good candidate for a LibreCMC port:

  • It ships with u-boot 1.1.1, Linux 2.6.32 and some vendor nonfree GNU/Linux distribution.
  • It has support in upstream Linux (in arch/mips/boot/dts/cavium-octeon/dlink_dsr-500n.dts)
  • It seems to have 128M of RAM and 32M of flash, so it's probably enough to run the web interface.
  • It has an Atheros mPCI WiFi card (probably ath5k compatible)

Though someone needs to do the work of:

  • Finding the vendor source code for u-boot and adding support for it in u-boot
  • Adding support for it in OpenWRT
  • Convincing LibreCMC to build images for it

Boot log

There is a console connector that uses an RJ45, but I've no idea of the pinout.


So to get the boot log I've connected a SOIC-16 adapter to the ADM3202 chip, and connected GND, RX, TX to an USB serial adapter that uses the full RS232 voltages.

I connected it in this way:

ADM3202 RS232 Adapter
PIN 15 (GND) PIN 5 (GND)
PIN 14 (T1 OUT) PIN 2 (RX)
PIN 13 (R1 IN) PIN 3 (TX)

I could then have the logs:

We can then login with the following data

And this doesn't give us a shell but a configuration console.

Note that it is also possible to have a shell in u-boot so it might be possible to get a GNU/Linux shell by passing arguments to Linux though the u-boot shell.
