I have developed a hardware design with Nios II processor using the DE0 board with Quartus v12. I am using a cpu, a sys clk timer, an interval timer, jtag uart, system id, sdram and pios. . When I run the nios program in C with SDRAM, it gets reset periodically after every 3.64 s (approx). I do not encounter this problem without SDRAM. Is there any setting that I need to change in order to prevent this?
