How to boot board from EPCS with NIOSII code running from SDRAM?

Hi Hareesh,

Thanks for your advice.

My first demo which the nios ii code runs on on-chip memoy: I followed the steps in the video, combined the .elf into .sof, convert it to .jic, and run successfully without problem.

However, the second demo(DE0_NANO_SDRAM_Nios_Test provided by Intel) which the nios ii code runs on external SDRAM memory: I tried to follow the steps, in the SDRAM contoller of the qsys system, I can't find the two options to check in the "Memory Initialization", as shown in this screenshot, do you have any idea?

Thanks again.
