As IMX6DQRM_revC says that GPIO peripheral can produce core interrupt. Does this mean all the GPIO pins support by i.mx6q are edge senstive and able to generate interuput to arm core?
Hello Jie Zou,
You can find the ARM Cortex A9 domain interrupt summary on Table 3-1 of the i.MX6 Reference Manual. You can use the GPIO signals to generate a Core Interrupt, and you can setup the interrupt trigger to low/high level or falling/rising edge on the GPIO interrupt configuration register.
I hope this helps,
