Hi everyone!
In imx6sx, I need to use gpio6_io01 for interrupt input in Linux and gpio6_io02 for interrupt input in M4.
However, during the test, it is found that only the last configured IO can respond to the interrupt. If gpio6_IO1 is configured first, and then gpio6_io02 is configured, only the A9 can respond to the interrupt. How to solve this problem?
Solved! Go to Solution.
Hi long
since this is combined interrupt, I am afraid it is not possible
to serve it simultaneously by both cores. May be useful to check
GPIO1 interrupts, they provide much more flexibility.
Best regards

Thank you very much for your reply. I try to replace IO in the test
