Welcome back!

The information you quote above is still current and I will try to find
some time to push forward with the review of Evgeniy Dushitov's
contribution soon.

I am not aware of anyone working with eCos on AT91SAM3 hardware. There
are existing Cortex-M variant ports for eCos on LM3S8xx, LPC17xx and
STM32 processor families so I would expect variant support for AT91SAM3
to be fairly straightforward. Hopefully some of the existing AT91
drivers can be reused for AT91SAM3.

I am sure that others within the eCos community will be interested in
variant support for AT91SAM3. Be sure to let us all know if/when you
start work on this.
