hi,

are you sure your component generate interupt?is your uart working well?you could try to set a variable, checking it in the main loop, and printf through uart-jtag or uart, using the hal library instead of writing register...

Hi Soin,

> are you sure your component generate interupt?# ## Yes , I am. I checked intr pin. It does go high whenever the counter reaches 7.

> is your uart working well?You could try to set a variable, checking it in the main loop, and printf through uart-jtag or uart, using the HAL library instead of writing register...# ## Yes , my UART is working well. I tested it in a seperate project by using this function in HAL library :

IOWR_ALTERA_AVALON_UART_TXDATA( UART1_BASE , &#39;Y&#39; );

After testing these stuff , I assign intr pin to irq in component editor , signal tab ; then recompile the System , Quartus project and NIOS IDE program but things are not better.

Have I got some steps missed ?

Thank you ,

Quan
