Hello, I have read threads about this issue but none of the proposed solutions solved my problem.
I'm facing issues when I tried to download the sw to the NIOS processor, the error message says Downloading ELF Process failed. I thought it was some mistake I had when creating the fpga project but I double check the design and it's good. I'm using the On-chip memory RAM for the NIOS II. I'm using the evaluation kit Cyclone 10GX from Intel.
Did you install WSL?:
It may be due to WSL not being installed or with the design, can you try one of the design below:
I did a fresh Quartus and Nios II install, and install WSL and tried one of the design above, it is working fine.
