Try to check what is the interrupt number you are trying to catch.

To make story short, this is the code:

alt_int_dist_target_set(ALT_INT_INTERRUPT_F2S_FPGA_IRQ3, 0x1);

alt_int_dist_trigger_set(ALT_INT_INTERRUPT_F2S_FPGA_IRQ3, ALT_INT_TRIGGER_EDGE);

alt_int_dist_priority_set(ALT_INT_INTERRUPT_F2S_FPGA_IRQ3, 1);

alt_int_dist_enable(ALT_INT_INTERRUPT_F2S_FPGA_IRQ3);

alt_int_isr_register(ALT_INT_INTERRUPT_F2S_FPGA_IRQ3, my_isr_callback, NULL);
