Dear Sirs:
I am developing an ethernet driver on omap3530 evm.
As this soc has no mac built-in, so I program gpio-99 to handle the interrupt.
But the test results show a long latency about 500ms after ISR starts to process the incoming interrupt, though the interrupt interval only is set to 1 ms.
BTW, I have set this gpio irq to the highest priority, however it seems not to work.
Could you experts kindly tell me how to solve this issue?
Thank you very much for help.
