Hello liuqimin,
What you are trying there will not work since the stdint.h is not included in the right file when the code is generated. You can replace the gpi_s32k_isr.tlc file attached in the toolbox under "src\mbdtbx_s32k\blocks\gpio" folder to make it work.
But, I don't recommend to build the blocks like this due to the following reasons:
Another issue is that the GPI ISR Control, must be placed in a part of the code not to be executed at each step time. Basically, like this the program will enable the interrupt to be triggered "when logic 1" so basically it will not do anything.
Our toolbox comes with the gpio_isr_control_s32k144 examples that shows how to enable and disable the interrupt.
Hope this helps,
Marius
