Problems when loading .sof file on to flash in DE2

[Altera_Forum]

Hi, 

  I created a .sof file using SOPC builder. I have added only standard components. .sof file is generated successfully. But when i tried to load it on to DE2 board I got following error:  Error: CONF_DONE pin failed to go high in device 1 Error: Operation failed  I did not specify Board in SOPC builder. Do I need to create a board description file? I am using quartus 5.0. I used mk_target_board. But I dont know how to proceed from there. Can anyone help me.   Regards, Mythri.

Hi, 

 You do not need to specify a board, so that is not the issue. You may have the RUN/PROG switch set to PROG, in which case you need to be loading a POF, not SOF; setting yo PROG uses the Active Serial mode to program the EPC chip for instead of programming the FPGA directly. See the DE2 User Manual for more instructions on using Active Serial programming. If this is the problem, you could also put the PROG/RUN switch back to RUN and then load the SOF into the FPGA.  There is a tutorial on Altera&#39;s University Program web pages for using the SOPC Builder with the DE2 board.  Regards,  --Steve    --- Quote Start ---  originally posted by mythri@Aug 28 2006, 11:01 AM hi,      i created a .sof file using sopc builder.  i have added only standard components.  .sof file is generated successfully. but when i tried to load it on to de2 board i got following error:  error: conf_done pin failed to go high in device 1 error: operation failed  i did not specify board in sopc builder. do i need to create a board description file? i am using quartus 5.0. i used mk_target_board.  but i dont know how to proceed from there. can anyone help me.   regards, mythri. <div align='right'><{post_snapback}> (index.php?act=findpost&pid=17907)  --- quote end ---    --- Quote End ---
