Hi Guys,

I just bought a new WesternDigital N900 wireless router, I think its very powerful according to the spec, but unfortrunately there is no OpenWRT ROM for this newer router, since WD published the source code for its firmware (http://support.wdc.com/product/download … mp;lang=en), Is it possible that someone make OpenWRT supports WD N900?

Thanks,

Read through the wiki again and found the following....
Given that support for the ubicom32 architecture has been removed from OpenWrt for being unmaintainable, it is unlikely that we will ever see OpenWrt for this router.

any news? nobody try to support? my wd n900c waiting for openwrt firmware;) i found on internet too many wd n900 users are unhappy with stock firmware, very unstable. we can make donations for a openwrt master..just do it:-)

Here is the boot output while connected to the serial header (JP4)
I'll gladly help in software development, maintenance and testing.
But I need help from a more experience user to get this project started.
It is my understanding that we should first try to get the toolchain for the architecture working.

Previous Ubicom processors were a bit odd & quirky since they didn't a have a Memory Management Unit (MMU) built in.
The IP8K changed this - we should be able to get some results if we patch the toolchain to enable the ubicom target once again.

A version of the Tool chain patch can be found here:
https://github.com/jameshilliard/ubicom … port.patch

Is there anyone that knows or wants to help to get this started?

any progress?((

I'm planning to attempt working on this, but waiting to hear from WD's legal team about some source code they are so far illegally refusing to provide me.
