the example 2c35 is nios2 dev board, not dsp board.

Thanks for your answer.

But, how about the error:

error: node instance "ddr_control" instantiates undefined entity "auk_ddr_controller"

Because as far as I know, the 2C35 Nios II development board doesn&#39;t used DDR.

Thanks,

Viet.

The CycloneII Developement Board does use DDR sdram. See the manual http://www.altera.com/literature/manual/mn...loneii_2c35.pdf (http://www.altera.com/literature/manual/mnl_nios2_board_cycloneii_2c35.pdf)

I found out that you have to inclued some vhdl files of the ddr sdram megacore component.

You can find them under <Your megacore directory>/ddr_ddr2_sdram-v3.3.0/lib.

Just add the .vhdl files to your QuartusII project.

Thanks every body for helping me!

I have another question, please help me.

Does any one have examples (or know any documents) about read/write on CF card using file IO functions instead of using read/write byte.

Thanks,

Viet.

You need OS support. There uCOS/2, eCos, and uClinux.

I prefer uClinux.

Thank you very much!

That problem was solved as your instruction.

But there are two errors that I don&#39;t know:

1) Error: Tcl error: can&#39;t find package ::ddr::settings

2) Error: Evaluation of Tcl script auto_verify_ddr_timing.tcl unsuccessful

How can I solve these errors?

Viet.

1. install ddr core 3.4.0

2. remove old ddr 3.3.0 lib path and ddr files in quartus II project files.

3. enter sopc build , there will be warning for unassigned pin of ddr, and set them to "assgined in quartus II".

4. regenerate sopc builder

5. compile in quartus again.

I did as your instructions, but when I ran SOPC Builder to regenerate, it issued an error:

error: in f:/altera/mywork/cf/cf_examples_for_niosforum/std_cf_2c35/std_2c35.ptf, can&#39;t read clock_source setting for ddr_sdram instance of ddr_sdram_component v3.2.0.

How can I fix this bug?

Thanks,

Viet.

Hi hippo,

Thank you very much for your help. I am just a beginner.

I have fixed that problem.

But I have another question.

As your instruction:

I downloaded zImage for 2C35 board: zimage_std_2c35. And then I downloaded this image to 2C35 board (ofcourse, after download .sof for it). This process finished successfully. But when I ran nios2-terminal there&#39;s no response from the board, the Nios II Command Shell only displayed:

[sopc builder]$ nios2-terminal --cable usb-blaster

nios2-terminal: connected to hardware target using jtag uart on cable

nios2-terminal: "usb-blaster [usb-0]", device 1, instance 0

nios2-terminal: (use the ide stop button or ctrl-c to terminate)

and did not return.

What is this error? How can I solve it?

Thanks.

Hi,

Anyone could help me?

I have the same problem when I try on EP2S60ES with zimage_std_2s60.

I don&#39;t know why.

Thanks a lot.

Viet.
