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. > Has anyone started work on the SAM3's? > How can I help? 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. John Dallaway eCos maintainer http://www.dallaway.org.uk/john
