Hi @Allen_2020,

Thank you for posting in Intel community forum and hope you are doing well.
Further clarification, do you mind explaining more on what do you mean by normal?
Also do you see any error or warning upon compiling?

There are some design example that you can refer to which is using the interrupt request here.
More details for the HAL Api function can also be found here.

Warm regards.

Hi Warm,
The normal return I said refers to the program running down after the interrupt registration is successful. The current phenomenon is that the program can't run out of the interrupt registration function. Debug locates to the following code:

static ALT_INLINE void ALT_ALWAYS_INLINE
alt_irq_enable_all (alt_irq_context context)
{
#if (NIOS2_NUM_OF_SHADOW_REG_SETS > 0) || (defined NIOS2_EIC_PRESENT) || \
(defined NIOS2_MMU_PRESENT) || (defined NIOS2_MPU_PRESENT)
alt_irq_context status;

NIOS2_READ_STATUS (status);

status &= ~NIOS2_STATUS_PIE_MSK;
status |= (context & NIOS2_STATUS_PIE_MSK);

NIOS2_WRITE_STATUS (status);
#else
NIOS2_WRITE_STATUS (context); // The debug program stops here
#endif
}
The code is compiled with no errors and more warnings, as shown below:
allen regards !

    Hi @Allen_2020,

    Looking on the code that you have, I am suspecting there might be something off with the way the alt_irq_register are invoked, maybe the parameters.
    Possible for you to share your quartus project for us to look into further more?

    Note: for the time being here is a different design example which make use of HAL api reference here and you can have a look at it. (download the example 'an459-design-files.zip', it is based on the following guideline)

    Warm regards.
