NIOS : IOWR works fine but writing through a pointer not

OK, I'll try this to check the burst transfer. There is appreciable cycle gap between two writes (IOWR) or reads (IORD) even if two write/read statements are placed next to each other with no other expression in between.

Regarding the pointer access, somehow, I have not been able to force a write or read transaction with pointers (not using the stio IOWR/IORD). As mentioned earlier the pointer expression below is not generating an write transaction on the slave port.

int *PtrToSlave = (int *) Avalon_MM_Slave_Base; // Slave base address

*PtrToSlave = (int) data;
