Unable to execute Hello World in Quartus Web edition

Hi,

.cdf stores Altera device programming information. You can use a Chain Description Files (.cdf) to program or configure a single device or one or more devices in a JTAG chain.

You can save it with different name or replace with existing one.

For more information refer below link.

Are you getting ELF error during build project or run as nios ll hardware? can you attach clear image or error text.

or delete the software folder and recreate it.

Best Regards,

Anand Raj Shankar
