Hi Patricia,

please take a look at the following document:

My First Nios II Software Tutorial-DebuggingTheApplication

page 13 of the PDF, you can see the example code, similar to what you've done but the first argument of the function IOWR_ALTERA_AVALON_PIO_DATA () is no the same as the example design, which should be LED_PIO_BASE instead of PIO_LED_BASE.

These are macros and should match with the ones existing on the libraries used.

In section Debugging the Application , you will find a way to see if there is a mistake on connections or something else.

Please let me know if this worked for you.

Regards,
