Hi Nvidia,

In NX ORIN, which GPIOs can be used by R5/SPE? Can all AON GPIOs be used by the SPE?
How is it configured for use in R5?

You are right, all GPIOs inside AON cluster can be accessed by SPE R5 core, unless they are occupied or unexported.

You can take a look at the file l4t-rt/rt-aux-cpu-demo-fsp/doc/gpio.md for more details.
