Supported in OpenWRT version: BARRIER BREAKER (Bleeding Edge, r38181) onwards.
Device Specific Terminology
On at least some WD N600 devices the ART-partition is named "radiocfg" in /proc/mtd. (knowing this could save you some time and/or allow proper pre-configuration backup.)
There are 3 methods. With newer versions of OpenWRT, it's likely only method 3 will work.
1) Download the file openwrt-ar71xx-generic-mynet-n600-squashfs-factory.bin
2) Configure your computers IP address to 192.168.1.10 and connect to a LAN port in the router.
3) Turn the router off.
4) Using a paperclip, press and hold the reset button on the bottom of the router and turn it on. Hold the reset button for at least 15 seconds. Wait until the power light on the front is slowly flashing on and off.
5) On your computer, visit http://192.168.1.1 NOTE: You will not be able to ping this address.
6) Upload the file openwrt-ar71xx-generic-mynet-n600-squashfs-factory.bin as downloaded earlier.
7) The router will now flash OpenWRT. This will take a couple of minutes to achieve. You can ping 192.168.1.1 and watch for ping replies to see when your router has rebooted into OpenWRT.
1) Visit the administration page on the router (http://192.168.x.x) and login.
2) Enter the following URL: http://192.168.x.x/telnet.php
3) Enable telnetd, click save.
4) Log in with username "Alphanetworks", password "wrgnd16_wd_db600"
5) Use wget to copy in the *factory.bin file
6) Call fwupdater -i *factory.bin
7) Ignore the failure message at the end of the upgrade, just reboot
1) Follow method 1, but instead of uploading OpenWRT use Gargoyle. Download
gargoyle_1.9.0-ar71xx-generic-mynet-n600-squashfs-factory.bin from the Gargoyle downloads page.
2) Once Gargoyle is flashed and the router is rebooted, go to 192.168.1.1 and update the firmware with
openwrt-15.05.1-ar71xx-generic-mynet-n600-squashfs-sysupgrade.bin from OpenWRT downloads.
3) After OpenWRT is finished flashing, log into the router by SSHing into email@example.com

Looking under the main 'can', the CPU is:
Next to that, there's what looks to be 2 x RAM chips:
Under the second smaller 'can', I see another Atheros Chip:
The UART is accessable via JP1 (which already has a header connected!). You will need a TTL to RS232 (ie a MAX232 circuit) to utilise this. See picture further down. The pinout is:
[TxD] [GND] [3.3v] [RxD]
