How can i run program in sdram?

I generate a CPU with Onchipram and sdram, and i new a project in NIOS II IDE with template hello_led,

when i build this project in onchipram, it works good,and i can access sdram correct, and then i build in sdram,when i run as hardware in NIOS IDE II, it also can works, but when i complilation in quartusII and download with jtag, it can not work,

i change the program`s memory options in hellow_led_syslib properties, set all three part to onchipram or sdram.

reset location is in onchipram!

anyone can tell me what`s wrong?

    Run as hardware is download by jtag,too.

    So what&#39;s your real problem? Is it after you recompiling in Quartus, that the system works not properly?

    when i use quartusii->tools->programer->JTAG to download&run, it did not works, atfer do that,nothing happened.

    so you say the run as hardware is run with jtag, i do not know the difference with the two ways.

    Hey dude

    You just download the Hardware Image using the Quartus .

    You need to download the Code using NIOS.

    Programming using Quartus & Nios are two completely different things. Both need to be done!!!

    Please go through the Getting started Guide.

    Thanks ppk031000.

    i`m new to NIOS, bought a board, then according the document with the board build my first CPU, i only use the board not more than 24 hours in my free times. You are right,i should first read the Guide, even my jod`s so busy and most of my sleep time of a day is less than 5 hours recently. so sorry for a dude` question! but i`m not a dude :-)

    i thought the sof or pof file is include the Code which i wrote in NIOD IDE, now i know it is not, maybe the code store in onchipram is in the sof ot pof file. but sdram not. Thanks!

    hey,friends

    I have a question to ask.

    When NiosII IDE run code,I know it downloads file via the JTAG cable,but which file?

    -------------Is it in hex format or bin format or something else?

    -------------Is it located in the code project (where my original code is)or

    ----------------------------in the hardware project (where *.sof *.pof is)?

    thanks

    Hi,

    here are some of the basics:

    usually IDE creates a folder in your project directory, called software\software_project_name.

    the source code is stored there. the file for download can be found under software\software_project_name\debug\ and

    it has the file extension .elf.
