Hi,

I’m porting FreeRTOS using Rowley CrossStudio (GCC).

The RTOS works at 100% but i still have problems with uIP (i can’t “PING” to my board).

If are interested tell me where i can send the files.

Regards.

Fabrizio.

Are you using the same hardware platform used by the demo in the download?

Could be something to do with structure packing.&nbsp; In IAR there is an option in the project for packing.&nbsp; I think in GCC would have to uase \_\_attribute\_\_( packed ) or something like that.
