[En-Nut-Discussion] branches/devnut_m3n: Status of device support

Hi STM users,

I am looking at using a STM32F207 device in a new project and was 
wondering if below status update us still valid. Has anybody tackled the 
EMAC driver yet?

And which would be the recommended gcc toolchain to use? Yagarto version 
29.04.2011 I suppose?

I am also researching suitable development boards. Looked at ST's and 
the IAR so far. Very limited choice on the market at this stage. And 
what about JTAG adaptors? Could the Turtelizer be used?. Any 
recommendations here would be greatly appreciated.
