regarding the interrupt-capability of GPIOs I have the following question: Is every GPIO able to trigger a hardware interrupt including the “native” GPIOs (GPIO00 to GPIO14) as well as the “secondary function” (customer usage) GPIOs (GPIO3_PA.xx to GPIO3_PZ.xx according to the Pinmux Config Template)?
We require more than the 15 “native” GPIOs for our custom carrier board design, so we are reliant on using the alternative GPIO function of several interfaces (as CAN_TX/CAN_RX, …).
I’m not sure if I understood your answer…
“Actually those GPIOs are same to Jetson.” → I understood that the GPIOs are the same at all members of the Jetson family?
“Does not have native or 2nd function diff.” What do you mean with this? diff = difference?
So, does every GPIO have an interrupt capability?
I’m sorry, I’m not a native speaker and even a beginner in issues of the Jetson family. So it is difficult for me to understand such thin answers.
“We don’t have anything called native or 2nd GPIO” → Yes, thats the reason why I put “native” and “secondary function” in quotes.
What i mean is: There are pins at the Jetson SoMs which are explicitly declared as “native” use as GPIOs (see in the column “Jetson Orin NX and Nano Function” from the Pinmux Config Template) as GPIO00 to GPIO14. And then there are pins with another native function which obviously may be used as GPIO as well (see column “Custommer Usage” in the Pinmux table) which I named as “secondary function”.
And I need to know if all of them (or only some specific or none) have the capability to release an hardware interrupt?
