I am looking at the STR912FW44:
It is a pretty nice part:
96 MHz ARM 9
All integrated on a single chip. Pricing looks reasonable with DigiKey showing about $17 and my disty promising < $10 in quantity.
I have been looking at the Atmel AT91SAM7X, but since the project got delayed and the STR912FW44 is now available, I am considering using it.
Are there plans to port FreeRTOS to the STR912FW44 ?
I may be able to arrange a development system if you need one.
