Hi all,
I want to modify the DE2_115 SD_Card Audio Player demo project for my own project and add the audio recording function to it. Basically it is like combining the Audio Player demo and the DE2_115_Audio demo projects together. I tried opening the SD_Card Audio Player project using Quartus 2 but I see only a Verilog file in the project. Where can I find the Block/Schematic file? And how can I use the available C source code in a new NIOS 2 project? Can someone give me the step by step procedure? ThanksLink Copied

I have tried compiling the DE2_115_SD_Card_Audio_Player project in Quartus 2. Then clicked on File -> Create/Update -> Create Symbol Files for Current File. It said Symbol file created successfully but I can't find it in the project directory.
After compilation, it shows DE2_115_SOPC:DE2_115_SOPC_inst under the main project in the Project Navigator. Double clicking on it opens the SOPC builder for the project. I tried generating this system again in the SOPC builder but it gives the following errors: Warning: Entity "altpll" obtained from "altpll.v" instead of from Quartus II megafunction library Error: Node "c0" is missing source File: C:/Users/.../AppData/Local/Temp/alt5789_2303333993077008292.dir/0027_sopcqmap/altpll.v Line: 243 Error: Node "c1" is missing source File: C:/Users/.../AppData/Local/Temp/alt5789_2303333993077008292.dir/0027_sopcqmap/altpll.v Line: 244 Error: Node "c2" is missing source File: C:/Users/.../AppData/Local/Temp/alt5789_2303333993077008292.dir/0027_sopcqmap/altpll.v Line: 245 Error: Node "c3" is missing source File: C:/Users/.../AppData/Local/Temp/alt5789_2303333993077008292.dir/0027_sopcqmap/altpll.v Line: 246 Error: Node "locked" is missing source File: C:/Users/.../AppData/Local/Temp/alt5789_2303333993077008292.dir/0027_sopcqmap/altpll.v Line: 248 Error: Node "readdata[0]" is missing source File: C:/Users/.../AppData/Local/Temp/alt5789_2303333993077008292.dir/0027_sopcqmap/altpll.v Line: 251 Error: Node "readdata[1]" is missing source File: C:/Users/.../AppData/Local/Temp/alt5789_2303333993077008292.dir/0027_sopcqmap/altpll.v Line: 251 Warning: Quartus II 32-bit Analysis & Synthesis was unsuccessful. 7 errors, 2 warnings Error: Peak virtual memory: 313 megabytes Error: Processing ended: Mon Mar 25 14:45:39 2013 Error: Elapsed time: 00:00:01 Error: Total CPU time (on all processors): 00:00:01 I just want to be able to modify the main.c file in NIOS 2 - Eclipse and use it for my own project.- Mark as New

Another query, as soon as I download the sof file from Quartus 2, the program starts running and it plays the audio files from the SD card. Shouldn't it wait for me to download the NIOS 2 code before running it?
I mean, in Quartus we simply create the system, with all the components and peripherals and a NIOS 2 soft processor. And then we use the Eclipse to download a source code for the NIOS 2 soft processor in the FPGA. But what I see in this project is somewhat different. It seems like the source code for NIOS 2 is also included in the Quartus 2 itself. Is it so? If yes, then where can I find that code?- Mark as New

In the NIOS II - Eclipse, I create a new project by selecting file -> new -> nios ii application and bsp from template. Then I select the existing DE2_115_SOPC.sopcinfo file to create a blank project.
Then I import the existing source file by clicking on file -> import -> general -> file system and select the \software\de2_115_sd_card_audio_player directory. Now when I build the BSP and the project, and try to run this file on the NIOS II hardware by right clicking on the project and selecting run as, I see only one option there: 1 local c/c++ application. There's no option for running this program as nios ii hardware. Where am I going wrong?- Mark as New
