Thank you for your understanding.


Back to your issue, it seems like a size problem with the SDRAM. The nios application could not fit in the SDRAM.

Could you try enabling the Small C library to further reduce the application size:

    Hi Jingyang,

    thanks for your Reply. I have actually two different Designs, one with Onchip Memory (SRAM) and another with SDRAM Controller. Both of them have issues. The issue you mentioned was with the SRAM not with SDRAM and also i am using NiosV. I didnt see any Option to enable the small C library in bsp editor, plus the small c doesnt support %f, while using printf, so i dont think thats gonna help me, as i need to use floating points in my Program.

    Regards,
