Honored ContributorDownloading ELF Process failed of Project
Good night everybody , I have problem of QuartusII 10.1sp1 .
My user chip is CycloneII EP2C35FC8 , when my sopc builder use Pll、SDRAM、FLASH、MCU、JTAG , I can run as hardware of holld_world . (Eclipse - Application and BSP from Template) But , when I return sopc builder and add EnthModule、DMA(*2-RX、TX)、 onchip momery(4096bytes)、timer . And Auto-Assign Base Addres、IRQS. Compilation after , I run as web_server_socket(rgmii) (Eclipse - Application and BSP from Template) , but message tell me , downloading elf process failed .
So , I try again run as holld_world , but message still tell me downloading elf process failed . Would like to ask anyone encountered a similar problem : ( ?

Altera_ForumYou must create an sdc file that lists at least all your external clocks. Then when you compile your design, look for any critical warning saying the timing requirements haven't been met. Have also a look in Timequest for the clock report and check that all your clocks have been detected correctly and are at the right frequency.

Dear Daixiwen
sorry Daixiwen , I don't know your mean ... My timing requirements problem of your mean ? but my pll only fore clk clk_0(exteral 50MHZ) 、system_clk(100MHZ) 、 sdram_clk(100MHZ -65deg) 、 enth_clk(25MHZ). At my sopc builder , only pll use clk_0 , other every use system_clk. To Blcok Diagram/Schematic File , sdram_clk for sdram clk of pin Enth_clk for Enth clk of pin , I still don't know my problem from where... - Altera_Forum
Is your design properly constrain and does it meet all timing requirements? When a design stop workings after adding some components usually indicates a timing problem. Adding some components should not cause the processor not to respond on the JTAG interface.

Dear Daixiwen
I reference your support and read some datasheet . I found , my problem maybe come from my memory config . In my project , when I just use (sopc builder) pll、nios、sdram、flash、jtag haven't problem . But , when I add Enth Module、DMA、on-chip(ram or rom) the niosII will tell me downloading elf process failed of project Near, I read datasheet of page 6 http://www.altera.com/literature/manual/mnl_avalon_spec.pdf I think ,maybe I need use FIFO Buffer(on-chip) replace on-chip(ram or rom) but I still tree , because i first use this fifo buffer(on-chip) - Altera_Forum--- Quote Start --- pausing target processor : not responding . --- Quote End --- This usually means one of the following:[list][*]you are in opencore evaluation mode and you closed the window after programming the FPGA[*]bad clock and/or reset signals[*]design not meeting timing requirements[/list]

Dear Daixiwen
Thanks your answer , I found my sopc builder , haven't System id component , so I add this component , moreover move the top and Auto-Assign Base Addres、IRQS . when I finish compilation , I programmer project for my board . (still keep open the programmer window) Then I use Eclipse and creat Application and BSP from Template . When I run as web_server_socket(rgmii) , the message still tell me downloading elf process failedbut appear the message befor , have other message . The message tell me assertion "m_state==state_debug" failed : file
"nios2oci.cpp",line 158
using cable "usb-blaster [usb-0]", device 1 , instance 0x00
pausing target processor : not responding .
resetting and trying again : /cygdrive/c/altera/10.1sp1
/nios2eds/bin/nios2-download : line 601: 2380 hangup.

You should have another error message before this one that tells you why the download failed.
Do you have a system id component in your sopc project? If not then add it first. It will ensure that you are using the correct configuration. IF you don't have a license for the Nios CPU you are using, then there is an opencore evaluation window that will open after you configure the FPGA. Don't close this window or the CPU will stop working. Check also that the design is properly constrained and meet all timing requirements.
