I was reading the HL_GPI interrupt usage. 

https://www.altera.com/support/support-resources/knowledge-base/solutions/rd05162013_937.html 

 

Consider i have the factory version of the default fpga image on my kit. Any guide for what is the procedure i need to do to enable the interrupt usage , i 'm trying this in bare metal basis?  

 

Tsik.

Hi the usage is similar like normal gpio, you can get some guide in the trm interrupt section.

Hi, first thing to do is clear all the mask, then configure interrupt edge, then write the polarity setting. Finally enable the interrupt. you can find the register accordingly in the TRM. you can try to check the interrupt activation via a register called gpio_intstatus.

No no, you can still look at how the register are configured in the firmware perspective. as the procedure to use this GPI is same like normal gpio..
