I found this site that takes development boards and makes them web accessible so you can download code to them like they were connected to your PC. They also give you access to software tools and a program that allows you to control the hardware such as cycle the power and reset the board. http://www.techonline.com/community/ed_resource/virtualab.

One of the labs they have is a Blackfin BF533 that you can load with the uClinux 2.6.8 Kernel. They also have embedded Linux on an i.MX21 but I havent checked that out yet.

I found out about this from another forum, has anyone else seen this stuff?
