Re: AXI GPIO Interrupt Handler not triggered in kernel module

Thank You for the response.

The UIO option tried earlier and working fine. AXI GPIO interrupt is a very fast interrupt (every 125us).

Faced issues with UIO in handling fast interrupt.

So i don't want to use the UIO / Sysfs method for handling interrupt. So custom Kernel module was tried but interrupt was not getting fired in driver.

Please help.

Regards
