Hello, 

 I have an altera cyclone (1c20) Nios-II dev board, and am attempting to get uclinux up and running. However, I&#39;m running into an odd problem when trying to upload...  I always get either <div class='quotetop'>QUOTE </div>  --- Quote Start ---  ------------------------------------------------ Microtronix Linux Extensions Version 1.3, Built December 30th, 2004 ------------------------------------------------ Feb 20, 2005 9:09:37 PM - (INFO) nios2-flash-programmer: Launching Quartus Progr ammer to download:   c:/altera/kits/nios2/components/altera_nios_dev_board_cyclone_1c20/system/a ltera_nios_dev_board_cyclone_1c20.sof Pre-Reading 1726KBytes of data from U5:     |----.----+----.----|     ******Read failed @00080000 Feb 20, 2005 9:10:20 PM - (SEVERE) nios2-flash-programmer: Error copying data to  the flash target[/b]  --- Quote End ---    The progress bar and "Read failed" address are inconsistent, but I have yet to get past this step.  OR I get something along the lines of...  <div class='quotetop'>QUOTE </div>  --- Quote Start ---  ------------------------------------------------ Microtronix Linux Extensions Version 1.3, Built December 30th, 2004 ------------------------------------------------ Feb 20, 2005 9:04:09 PM - (INFO) nios2-flash-programmer: Launching Quartus Progr ammer to download:   c:/altera/kits/nios2/components/altera_nios_dev_board_cyclone_1c20/system/a ltera_nios_dev_board_cyclone_1c20.sof Feb 20, 2005 9:04:19 PM - (SEVERE) nios2-flash-programmer: Error opening target  hardware Failed to get header for variable-payload packet. Feb 20, 2005 9:04:19 PM - (SEVERE) nios2-flash-programmer:    Unable to open fla sh-device after successfully communicating  with target. It is likely that you are using a flash-programming FPGA design which was not created for your target board.    In order to program flash, you must first create a purpose-built   flash-programming design (i.e. FPGA configuration) and associate it with   your particular board.  The Nios development kit is delivered with purpose-bui lt   flash-programming designs pre-built for several development boards.  If you wi sh   to program flash on your own board, you must first create a flash-programming   design.    The process of creating a flash-programming design for your board is mostly   automated.  From a bash-shell, execute this script:          mk_target_board --help    The help-message includes references to other documentation on programming   flash and targeting Nios systems to custom board designs.  - exiting.[/b]  --- Quote End ---    With inconsistant "SEVERE" messages, but generally along the lines of what&#39;s above.  The odd thing is that I can program this .sof just fine using the Quartus programmer, and, unfortunatly, when I do so, nios2-flash-programmer attempts to reprogram it.  Any thoughts? Could this be a hardware issue? Any help would be greatly appreciated, as I&#39;m at a bit of a loss at this point.  Thanks, --Nate

After several hours of repetedly attempting to flash various files different ways, finally some progress, but still not quite there.

I&#39;ve also encountered the: 

  Feb 20, 2005 9:04:19 PM - (SEVERE) nios2-flash-programmer: Unable to open flash-device after successfully communicating with target.   error. This problem went away after I upgraded to Quartus 4.2  Hope this helps.  Terry G.
