Hi All, In PacketRxReady(struct i82559* p_i82559) of i82559.c the code says that the unless some thing appears on the Network card and the rxstatus bit get changed the control/execution will be in while(1). But to my surprise when i am debugging the code inside while(1) , i saw it is jumping out of it for some reasons even no packet was entering into the wire or out of the wire. Is it something that the timeout was set anywhere or else any seperate thread running for input packets processing and output packet processing. thanks in advance . Sorry for the trivial doubt but being new to RTOS concepts, i am eager to know the operation. ..for easy reference, below given is part of the code inside PacketRxReady(struct i82559* p_i82559) while ( 1 ) { cyg_uint32 rxstatus; cyg_uint16 rxstatus_hi; READMEM32(p_rfd + RFD_STATUS, rxstatus); if (0 == (rxstatus & RFD_STATUS_C)) break; .......... } regards srinivas
