Downloading ELF Process failed in Quartus II 10.1sp1

If you just want to download the ELF to the FPGA, try creating a batch file using notepad with the lines between the start and end comments. Do not include the start and end comments. Then using notepad create a elf_downloader file with no extension using the lines between the start and end comments. Do not include the start and end comments.

Put all files in a temporary folder:

YOUR_BATCH_FILE.BAT

YOUR_ELF_FILENAME.ELF,

YOUR_SOF_FILENAME.SOF,

elf_downloader

You probably will also have to create the system variable:

Step1: Go to Control Panel

Step2: Go to System

Step3: Go to the Advanced System Properties

Step4: Go to the Advanced Tab

Step5: Go to Environment Variables

Step6: Press the "New" button

Step7: Enter the Variable Name and Value below:

Variable Name: SOPC_KIT_NIOS2

Variable Value: C:\Altera\10.1sp1\nios2eds (your path may be different)

Lastly, Double click the batch file.
