i.MX8M Mini interrupt capable GPIOs

Hi,

I am using i.MX8M Mini processor (MIMX8MM4CVTKZAA) in one project having industrial surveillance application.

In datasheet, i am not able to find any information explicitly about which GPIO is interrupt capable and which is not. Can you please help me on this? I need details of GPIOs which are interrupt capable.

Thanks in advance,

Nikhil

Hi Nikhil

all gpios are interrupt capable, details can be found in Chapter 7 Interrupts and DMA,

sect.8.3 General Purpose Input/Output (GPIO)

i.MX 8M Mini Applications Processor Reference Manual

Best regards

Hi,

Another query regarding the same project.

In datasheet, i am not able to identify behavior of ENET0_TD2 pin in RMII and RGMII mode. There may be some typo error i think (not sure about this). Refer attachment.

For your information, we want to use RMII mode.

As per my understanding, for RMII mode, this pin has two options; one for generating 50MHz clock and second for receiving 50MHz clock. And these two options are software configurable. Please confirm if i am right. If not, please help me to understand this.

Thanks in advance,

Nikhil
