I did a port of eCos to the STR912FW a year or so ago. It took me about two weeks to get a basic system working. It was my first port, and I cut a few corners along the way, but it ended up working well. I didn't have a JTAG debugger so I was reduced to bringing up the startup code and serial console by using a combination of LEDs, coffee and late nights. I'm no longer involved with the company so I don't know the current status of the port, but I don't believe the source is available.
