I want to use Interrupts on ISI controller, but I don`t know ISI IRQ? What is it?

Hi,

You can find this information in the SAM9263 datasheet.
In chapiter 10, the IRQ coresponding to the Peripheral ID.
In your case, for ISI is IRQ 25.

I find this ID. I use this ID in function KernelIoControl and Sysintr in InterruptInitialize. But I don`t view interrupt on ISI. Does evalution BSP work with ISI interrupt? If yes, can You post me example use this controller ISI.

The BSP does not contain ISI driver.
You must develop the driver by your own.

To use ISI interrupt, you need to request a sysintr by using KernelIoControl(HAL_REQUEST_SYSINTR, ....).
Then use the InterruptInitialize api to link the sysintr with a event.

I do KernelIoControl and InterruptInitialize. But then I see AIC->IECR for ISI (25), there is no set bit. Then I set this bit (eneble AIC to interrupt by ISI) and interrupt from ISI is appears, Windows is stopped and down.
