Full On-Chip Memory

Hi, I'd like to know how to determine if the memory space of an on-chip memory is full. In my nios II system, I generated an on-chip M4K memory. It's size is 4096 bytes with a 32 bits data...

Hi Daixiwen and dsl,

Now I understand what happens when I write a string. Thank you.

By the way, if will write a continuous bit stream into the memory, if the 4byte space is full will the data automatically be stored in the next 4bytes?

Also when I do this:

IOWR_32DIRECT(mem1, 0x00, 0x54);

and try to read 0x00 until 0x03 i get:

0x00: 54

0x01: 54

0x02: 54

0x03: 54

Why is this so?

Thank you.
