hi all,
i m novice to this rabbit world still i have worked on some sample codes. but I m facing problem with sample code in TCP/IP on RCM 4300 target board with Dynamic C10 version.
in the sample code itself, they have declared as
1. " if CPU\_ID\_MASK(_CPU\_ID_) \>= R4000 "
2. fatal “This sample is not currently supported by Rabbit 4000 based products.”
#endif
so does it implies that tcp/ip will not work for processor id \> 4000?
please help me. thank you !!!
