GPIO interrupt loss

[jimlin]

Hi I set one GPIO interrupt with low-to-high sense, but seems it did not triggle the interrupt when SD run. I want to confirm the SD would make the interrupt loss? If so, how to raise up the GPIO interrupt priority?

Thanks.

SD can delay app interrupt because SD interrupts have higher priority than app interrupts. i do not think that any interrupts are lost.

Thanks for reply. But, it seems lost in fact, for the GPIO has been set from low to high, but no interrupt triggle, for I added another GPIO toggle in the interrupt service while nothing happened. Any other possible?
