I am using a small footprint EP4CE6 FPGA with NIOSII built using 20KB on chip memory. Using Eclipse IDE I built the "small hello world" example as a starting point. My problem is that when I add anything more than a simple alt_printf statement, the cpu continuously resets itself.I think it may be because I am not setting up the complier correctly. The instructions refer to the old NIOS IDE. I would like to know how to set these using the ECLIPSE IDE. - Define the preprocessor option ALT_NO_INSTRUCTION_EMULATION - Set Periodic system timer and Timestamp timer to none - Set Max file descriptors to 4 - Uncheck Clean exit (flush buffers) and any other settings you think is necessary to run NIOS CPU with on-chip memory only. Thanks, nathan
